Elkhart County
Countywide 12 OOOOEST
0700EST
Thunderstorms continued to develop and move
from west to east for several hours across
mainly the southern part of Elkhart County.
While many locations saw 2 to 4 inches of
rain, which did cause some localized urban
issues, a narrow band of much heavier rain set
up from Wakarusa east into Millersburg. By the
end of the event an off duty NWS employee
reported 8.17 inches in his gauge with another
employee only a few miles south of him
reporting 4.50 inches and spotters
reporting 6.65 inches west of Goshen. The
heavy rainfall resulted in many roads in this
narrow band being closed as water flowed over
them for several hours. Some roads had minor
washouts with extensive erosion along many of
the ditch banks. At least 24 businesses in
Elkhart suffered damage with a few of these
having to suspend operations until the water
could recede and clean up commence. Damage
was reported approaching 1.5 million dollars,
assessed from a combination of actual property
loss, as well as loss production and
income. Luckily, no evacuations were needed,
but there were some rescues of people from
vehicles that became stranded in the flood
waters. This included a police car along State
Route 119.

county moved across parts of southern
Lagrange county, from Topeka to Oliver
Lake. Topaka was the hardest hit area with at
least 22 homes reporting some sort of damage
from the flash flood. Numerous roads were
flooded and closed in and around Topeka. 9
inches of rain was recorded in the Oliver
Lake area before tapering off after 3 am
EDT. Numerous streams that feed into the lake
and rainfall over the lake itself resulted in
the lake level rising 0.70 inches over the
normal stage at the DNR dam. Water covered
many of the piers with some boats floating on
shore or into other craft. Also several
roads around the lake had water flowing over
them. One structure sustained water damage on
the lake. Damage is estimated at $400.000.

A cold front dropped southeast across the
state during the day on the 1st into the
evening hours. By midnight...the front
extended east-northeast to west-southwest
across southern Iowa. The soundings
indicated a considerable amount of dry air
in the low levels, thus preventing the
formation of tornadoes. The LCL was in the
5500 to 6000 foot range during the event.
High temperatures warmed into the upper
80s over far northwest Iowa, to the 95 to
100 degree range over the south. Dew points
were generally in the upper 50s to mid 60s
except along the frontal boundary. Moisture
pooled along the boundary with dew points
rising into the low 70s. The atmosphere
became quiet unstable with lifted indices
around -9 C. and CAPE values in the 3500
to 4500 J/kg range. There was some shear
available, but it wasn't all that strong.
Generally shear in the zero to 3 km layer
was in the 25 to 30 kt range. The freezing
level was quite high, being in the 14,500
to 15,000 foot range. Thunderstorms fired
initially just to the north of the boundary
in northwest and north central Iowa, along
the north edge of the mid level cap. The
storm development was enhanced as a jet
speed max raced across southern North Dakota
into Wisconsin during the late afternoon,
putting Iowa in the 3rd quadrant, or right
entrance region, of the jet. These storms
produced three quarter to one inch diameter
hail in a few areas. The largest hail
occurred in the Clear Lake area and was the
size of half dollars. Gusty winds were also
reported, however most were in the 35 to 50
MPH range. One wind gust to around 60 MPH
downed tree limbs in Humboldt County at
Bradgate. As the evening progressed, an
outflow boundary from the convection in the
north pushed south into central Iowa.
Scattered thunderstorms developed along the
boundary, but most were not severe. One storm
produced a 62 MPH wind gust as it passed over
Grimes in Polk County. The storm had formed
along the outflow boundary, but weakened
quickly as the outflow boundary undercut the
storm. Thunderstorms continued to fire during
the night to the north of the actual frontal
boundary. These were quite elevated. One of
the storms became severe briefly and dropped
one inch diameter hail southeast of Boxholm
in Boone County.

A nearly stationary front extended northeast
to southwest across the state. An outflow
boundary was in place from previous
convection and extended from low pressure in
Kansas, across northern Missouri, into
northern Illinois. The airmass remained
fairly unstable with temperatures north of
the outflow boundary in the 80s and dew
points near 70. Sufficient heating took place
over Missouri south of the outflow boundary
to erode the CIN that was in place. CAPE
values reached 2000 to 4000 J/kg by the late
afternoon with lifted indices around -6 C.
Thunderstorms formed in the vicinity of the
outflow boundary and drifted northeast. There
was some shear in place with zero to 3 km
shear in the 25 to 35 kt range. The storms
became severe with several reports of three
quarter to one inch diameter hail received.
One of the storms produced high winds west of
Blockton in Taylor County. The freezing level
was quite high, limiting the hail size
somewhat as it was in the 13,500 to 14,100
foot range. As was the case the previous day,
there was considerable dry air in the lower
levels. As a result, the LCL was in the 1200
to 1400 meter range and limited the potential
for tornadic development.

The frontal boundary that had been across
Iowa the past few days remained stationary
across the state during the afternoon. Two
other weather features interacted with the
airmass during the late afternoon hours.
One was a mesoscale convective vorticity
maximum that moved from southern Nebraska,
east toward Iowa. A strong upper level trough
of low pressure dropped southeast out of
Canada, along with its associated cold
frontal boundary, into Iowa late in the day.
The airmass became very unstable by late
afternoon with high temperatures in the mid
to upper 80s and dew point temperatures in
low 70s. Lifted indices dropped to the -7 to
-12 C. range with CAPE values in the 3500 to
5500 J/kg range. The freezing level was quite
high int he 13,800 to 14,600 foot range,
limiting the hail size in spite of the CAPE
of 300 to 500 J/kg in the -10 C. to -30 C.
layer. The tornado theat was limited by the
LCL height being in the 800 to 1600 meter
range. Thunderstorms developed in western
Iowa initially with a few severe storms
reported. Some of the initial thunderstorms
produced high winds with 20 inch diameter
tree branches broken off in Humboldt County
at Livermore. As the late afternoon and
evening progressed, a line of thunderstorms
formed along the cold frontal boundary. Shear
in the 30 to 40 kt range helped maintain the
storms. There were reports of quarter size
hail from some of the cells. Wind became more
of an issue later in the event. Along the
line that formed along the northern cold
front, winds gusted to 61 MPH in the Fort
Dodge area and winds near 60 MPH west of
town. The winds caused an accident on U.S.
Highway 20 near Moorland. As the storms
progressed southeast, strong winds moved
through the Des Moines metro area.
Railroad crossing arms were broken by the
high wind in Des Moines. Farther southeast,
near Hartford, wind gusts were estimated
around 65 MPH by an off duty NWS employee.
Franklin County
2 SE Popejoy 11 0530CST
11000ST
An upper level low pressure system lifted
northeast into the central U.S. out of the
Monsoonal flow in the southwest U.S. The low
was slow moving as it advanced across the
area. A considerable amount of moisture was
drawn north ahead of the system with
precipitable water values in the 1.75 to 2.25
inch range. As the low advanced northeast,
a large area of rain and embedded
thunderstorms developed. The system took on
characteristics of a cool season system with
a large deformation zone forming along the
north edge of the system. With the deep
moisture in place, copious amounts of rain
fell in a narrow band, about 30 miles wide,
extended east of Omaha to north of Waterloo.
Rainfall amounts of 2 to 5 inches were common
in this area. The heaviest rain fell north of
Des Moines at Popejoy in Franklin County.
Official rainfall totals from the area were
around 8 inches, with some unofficial amounts
as high as a little over 9.5 inches. Radar
estimates show that between 3 and 5 inches of
the rain fell in the hour between 0500 and
0600 CST. The heavy rain caused flash
flooding southeast of Popejoy with several
county roads being closed by high water
flowing over the road.

A weak frontal boundary extending from
northwest Minnesota into southwest Kansas
advanced toward Iowa. The flow was very week,
but the airmass was very moist. Precipitable
water values were above 2 inches with a deep
warm layer in place. The freezing level was
between 14,500 and 15,500 feet. The CAPE in
the -10 to -30 layer was significant at
800 J/kg, but in spite of that there was
little hail due to the very high freezing
level. Afternoon temperatures warmed in to
the upper 80s to low 90s with dew points in
the mid 70s. This pushed the most unstable
CAPE to around 5500 J/kg. Lifted indices were
in the -9 to -11 range by late afternoon.
Tornadoes did not occur with a weak
shear environment (under 20 kts) and with an
LCL of 1000 to 1200 meters. There was a fair
amount of DCAPE available, about 1500 J/kg.
Thunderstorms formed in three areas as the
afternoon progressed. One area was in
northwest Iowa, with the second over eastern
Nebraska moving into west central and
southwest Iowa. The third area was
smaller with development over the southeast
counties of the state. Initially the storms
produced some marginally severe half of three
quarter to one inch in diameter. As the
afternoon progressed, the two clusters in
northwest and southwest Iowa merged, and the
systems over the west took on more of a
storms over the southeast weakened. The
linear structure and the event transitioned
into a wind event. There were several reports
and power lines downed by the high winds. The
strongest winds was of trees measured at 75
MPH in Adair.

A very unstable airmass was in place over
Iowa during the afternoon of the 17th, though
it was also quite capped. The 700 mb
temperature was in the 14 to 15 C. range,
making it difficult for thunderstorm
activity to initiate. Plenty of moisture was
values in the 6000 to 8000 J/kg range based
on the surface, and near 5000 J/kg in the
mixed layer. Lifted indices fell to near -14
C. by the late afternoon as well. With the
exception of the surface, the lower levels
were fairly dry. The LCL was in excess of 2
100 meters by late afternoon. There was
plenty of potential for hail with -10 to -30
C layer CAPE in excess of 1000 J/kg, though
the freezing level was in excess of 15,500
feet. Low level lapse rates were in the 8 to
9 C. range in the zero to 3 km layer. The
shear environment was fairly favorable by
late afternoon with 30 to 40 kts of effective
shear. A cold front moved southeast across
the state during the afternoon. Ahead of it,
a hot and very moist airmass was in place.
Afternoon highs were in the mid 90s to around
100 with dew points in the mid to upper 70s.
Thunderstorms were not able to fire until the
late afternoon hours and only over the far
the storms did form, the mode of severe
weather was hail. Hail of golf ball, upwards
of 3 inch diameter fell in Black Hawk County
at Waterloo. The hail path began near the
airport and then tracked southeast through
downtown Waterloo, causing extensive damage.
Tama, Wapello, and Davis Counties were also
hit with large hail. Hail of nearly baseball
size pelted the countryside south of
Bloomfield. One brief tornado touched down
in Tama County near Tama. It touched down
in an open area just west of town and caused
little damage. During the afternoon hours,
temperatures in Des Moines reached 100
degrees for the first time since August of
2003. An 83 year old woman was overcome by
heat and found dead in her back yard around
1530 in the afternoon.

An extremely unstable and hot airmass was in
place over Iowa during the day on the 19th.
The weather situation was complicated with a
warm front extending from northwest into
central, into southeast Iowa during the mid
afternoon. Earlier in the day, and MCS moved
across north central into east central and
southeast Iowa. This MCS laid down an outflow
boundary that pushed southwest into the
state, and eventually met up with the warm
front. Along and southwest of the
boundary, considerable dew point pooling took
place. Afternoon temperatures reached the
upper 90s to near 105 with dew points in the
upper 70s to mid 80s. CAPE values soared to
the 8000 to 10,000 J/kg range by early
evening as the lifted index fell to the -10
to -15 C. range. A very strong cap was in
place with 700 mb temperatures warming
to between 14 and 17 C. The freezing level
was unusually high, in the 16,500 to 17,000
foot range. Thunderstorms tried to develop by
the early evening, but as additional warmer
and drier air pushed into the area the
dissipated. After sunset a cluster of
thunderstorms developed over southern
Minnesota and northern Iowa along the north
edge of the cap as a cold front pushed into
the state from the northwest. The shear
environment was quite favorable with shear in
the 55 to 70 kt range in the zero to 6 km
layer. The storms eventually developed into
an MCC and skirted the northern edge of IOWA,
Central Iowa. They produced strong winds and
some hail. The hail was limited by the very
warm airmass with reports of hail in the
penny to nickle size range. High winds caused
damage to trees and power lines with wind
speeds in the 60 to 70 MPH range with the
stronger storms in the Winnebago, Worth, and
Bremer County areas of north central and
northeast Iowa.

Iowa was between a quasi-stationary frontal
boundary to the north and a developing warm
front to the south. The airmass became quite
unstable as afternoon highs reached the upper
80s to mid 90s with dew point readings in the
low 70s. The lifted index fell to -7 C. by
late afternoon with CAPE of 3000 to 3500
J/kg. The LCL was fairly high in the 1000 to
2000 meter range. The airmass was very warm
with the freezing level around 15,300 feet.
Thunderstorms developed over central and
southeast Iowa during the late afternoon
hours and continued into the evening. The
shear environment was reasonably favorable
with 30 to 40 kts of shear in the zero to 3
km layer. The storms produced spotty high
winds and hail of up to an inch in diameter.
Trees were downed as well as 2 power poles in
Poweshiek County. In addition, a machine shed
was also lifted a foot off of the ground. In
Mahaska County, high winds ripped the siding
off of a house west of Leighton. The storms
produced heavy rainfall with precipitable
water values around 2 inches. Rainfall of 1
to 3 inches occurred with the heavier storms
in a period of an hour or so.

The airmass remained quite unstable across
Iowa as the night progressed. Thunderstorms
developed north of the southern boundary
mentioned above, as the low level jet
increased. Though most of the storms were not
severe, a small area of severe storms
developed in Union County. Four farmsteads
suffered wind damage as the storms moved
through. Trees were downed by the high winds
with damage at one house placed at $10,000,
and $5,000 at another due to trees falling on
the houses. Crop damage occurred as a result
of half inch diameter hail that fell along
with the winds.

An upper level disturbance initiated two
supercell thunderstorms in a moist to near
tropical atmosphere that was ahead of a cold
front in eastern Iowa. Outflow from the
supercells developed a broken line of of
storms that moved through Iowa and into
Illinois and Missouri. The line produced
sporatic pulse severe storms from east
central Iowa into northwest Illinois. The
more solid part of the line produced a
considerable amount of severe weather from
east central Iowa into northern Missouri.

From July 16-20, a deadly heat wave gripped
much of central, south-central and southeast
Kansas. Broad high pressure in the mid and
upper levels of the atmosphere caused
temperatures to soar into the 105-110 degree
range, with afternoon heat indices about the
same. The cover of darkness provided little
in the way of relief, as overnight
temperatures were slow to fall off, reaching
only the upper 70s by sunrise for some
locations. Unfortunately, the prolonged heat
claimed five lives across south-central
and southeast Kansas, most of them elderly
men. Three occurred in Wichita, one in Iola,
and another in Coffeyville. The heat
unofficially claimed three other lives, two
in Wichita and one in Coffeyville.
Additionally, dozens of individuals across
central, south-central and southeast Kansas
were treated for heat-related illnesses.

Two large wildfires burned out of control for
several hours across portions of Ellsworth
and Lincoln Counties on Sunday, July 30th.
The first blaze started late Sunday afternoon
in Ellsworth County, just north 1-70 between
mile markers 207 and 208. Southerly winds
of 35 mph rapidly spread the fire north into
southwest Lincoln County, where it raged out
of control and did the majority of its
damage. One family had to be evacuated from
their home. As this fire continued to spread,
a second blaze ignited a few hours later
just north of Sylvan Grove, near the junction
of highways 181 and 18. Both blazes were
eventually brought under control, and were
finally extinguished by early Monday morning,
but not before consuming over 1,000 acres of
grassland. Utility poles, trees and fence
lines were destroyed, but no major
structures were lost. Fortunately,
no injuries or deaths occurred.

Thunderstorms continued to develop and move
from west to east for several hours across
mainly the southern part of Elkhart County.
While many locations saw 2 to 4 inches of
rain, which did cause some localized urban
issues, a narrow band of much heavier rain set
up from Wakarusa east into Millersburg. By the
end of the event an off duty NWS employee
reported 8.17 inches in his gauge with another
employee only a few miles south of him
reporting 4.50 inches and spotters
reporting 6.65 inches west of Goshen. The
heavy rainfall resulted in many roads in this
narrow band being closed as water flowed over
them for several hours. Some roads had minor
washouts with extensive erosion along many of
the ditch banks. At least 24 businesses in
Elkhart suffered damage with a few of these
having to suspend operations until the water
could recede and clean up commence. Damage
was reported approaching 1.5 million dollars,
assessed from a combination of actual property
loss, as well as loss production and
income. Luckily, no evacuations were needed,
but there were some rescues of people from
vehicles that became stranded in the flood
waters. This included a police car along State

A cold front dropped southeast across the
state during the day on the 1st into the
evening hours. By midnight...the front
extended east-northeast to west-southwest
across southern Iowa. The soundings
indicated a considerable amount of dry air
in the low levels, thus preventing the
formation of tornadoes. The LCL was in the
5500 to 6000 foot range during the event.
High temperatures warmed into the upper
80s over far northwest Iowa, to the 95 to
100 degree range over the south. Dew points
were generally in the upper 50s to mid 60s
except along the frontal boundary. Moisture
pooled along the boundary with dew points
rising into the low 70s. The atmosphere
became quiet unstable with lifted indices
around -9 C. and CAPE values in the 3500
to 4500 J/kg range. There was some shear
available, but it wasn't all that strong.
Generally shear in the zero to 3 km layer
was in the 25 to 30 kt range. The freezing
level was quite high, being in the 14,500
to 15,000 foot range. Thunderstorms fired
initially just to the north of the boundary
in northwest and north central Iowa, along
the north edge of the mid level cap. The
storm development was enhanced as a jet
speed max raced across southern North Dakota
into Wisconsin during the late afternoon,
putting Iowa in the 3rd quadrant, or right
entrance region, of the jet. These storms
produced three quarter to one inch diameter
hail in a few areas. The largest hail
occurred in the Clear Lake area and was the
size of half dollars. Gusty winds were also
reported, however most were in the 35 to 50
MPH range. One wind gust to around 60 MPH
downed tree limbs in Humboldt County at
Bradgate. As the evening progressed, an
outflow boundary from the convection in the
north pushed south into central Iowa.
Scattered thunderstorms developed along the
boundary, but most were not severe. One storm
produced a 62 MPH wind gust as it passed over
Grimes in Polk County. The storm had formed
along the outflow boundary, but weakened
quickly as the outflow boundary undercut the
storm. Thunderstorms continued to fire during
the night to the north of the actual frontal
boundary. These were quite elevated. One of
the storms became severe briefly and dropped
one inch diameter hail southeast of Boxholm
in Boone County.

A nearly stationary front extended northeast
to southwest across the state. An outflow
boundary was in place from previous
convection and extended from low pressure in
Kansas, across northern Missouri, into
northern Illinois. The airmass remained
fairly unstable with temperatures north of
the outflow boundary in the 80s and dew
points near 70. Sufficient heating took place
over Missouri south of the outflow boundary
to erode the CIN that was in place. CAPE
values reached 2000 to 4000 J/kg by the late
afternoon with lifted indices around -6 C.
Thunderstorms formed in the vicinity of the
outflow boundary and drifted northeast. There
was some shear in place with zero to 3 km
shear in the 25 to 35 kt range. The storms
became severe with several reports of three
quarter to one inch diameter hail received.
One of the storms produced high winds west of
Blockton in Taylor County. The freezing level
was quite high, limiting the hail size
somewhat as it was in the 13,500 to 14,100
foot range. As was the case the previous day,
there was considerable dry air in the lower
levels. As a result, the LCL was in the 1200
to 1400 meter range and limited the potential
for tornadic development.

The frontal boundary that had been across
Iowa the past few days remained stationary
across the state during the afternoon. Two
other weather features interacted with the
airmass during the late afternoon hours.
One was a mesoscale convective vorticity
maximum that moved from southern Nebraska,
east toward Iowa. A strong upper level trough
of low pressure dropped southeast out of
Canada, along with its associated cold
frontal boundary, into Iowa late in the day.
The airmass became very unstable by late
afternoon with high temperatures in the mid
to upper 80s and dew point temperatures in
low 70s. Lifted indices dropped to the -7 to
-12 C. range with CAPE values in the 3500 to
5500 J/kg range. The freezing level was quite
high int he 13,800 to 14,600 foot range,
limiting the hail size in spite of the CAPE
of 300 to 500 J/kg in the -10 C. to -30 C.
layer. The tornado theat was limited by the
LCL height being in the 800 to 1600 meter
range. Thunderstorms developed in western
Iowa initially with a few severe storms
reported. Some of the initial thunderstorms
produced high winds with 20 inch diameter
tree branches broken off in Humboldt County
at Livermore. As the late afternoon and
evening progressed, a line of thunderstorms
formed along the cold frontal boundary. Shear
in the 30 to 40 kt range helped maintain the
storms. There were reports of quarter size
hail from some of the cells. Wind became more
of an issue later in the event. Along the
line that formed along the northern cold
front, winds gusted to 61 MPH in the Fort
Dodge area and winds near 60 MPH west of
town. The winds caused an accident on U.S.
Highway 20 near Moorland. As the storms
progressed southeast, strong winds moved
through the Des Moines metro area.
Railroad crossing arms were broken by the
high wind in Des Moines. Farther southeast,
near Hartford, wind gusts were estimated
around 65 MPH by an off duty NWS employee.
Franklin County
2 SE Popejoy 0 0 10K
An upper level low pressure system lifted
northeast into the central U.S. out of the
Monsoonal flow in the southwest U.S. The low
was slow moving as it advanced across the
area. A considerable amount of moisture was
drawn north ahead of the system with
precipitable water values in the 1.75 to 2.25
inch range. As the low advanced northeast,
a large area of rain and embedded
thunderstorms developed. The system took on
characteristics of a cool season system with
a large deformation zone forming along the
north edge of the system. With the deep
moisture in place, copious amounts of rain
fell in a narrow band, about 30 miles wide,
extended east of Omaha to north of Waterloo.
Rainfall amounts of 2 to 5 inches were common
in this area. The heaviest rain fell north of
Des Moines at Popejoy in Franklin County.
Official rainfall totals from the area were
around 8 inches, with some unofficial amounts
as high as a little over 9.5 inches. Radar
estimates show that between 3 and 5 inches of
the rain fell in the hour between 0500 and
0600 CST. The heavy rain caused flash
flooding southeast of Popejoy with several
county roads being closed by high water
flowing over the road.

A weak frontal boundary extending from
northwest Minnesota into southwest Kansas
advanced toward Iowa. The flow was very week,
but the airmass was very moist. Precipitable
water values were above 2 inches with a deep
warm layer in place. The freezing level was
between 14,500 and 15,500 feet. The CAPE in
the -10 to -30 layer was significant at
800 J/kg, but in spite of that there was
little hail due to the very high freezing
level. Afternoon temperatures warmed in to
the upper 80s to low 90s with dew points in
the mid 70s. This pushed the most unstable
CAPE to around 5500 J/kg. Lifted indices were
in the -9 to -11 range by late afternoon.
Tornadoes did not occur with a weak
shear environment (under 20 kts) and with an
LCL of 1000 to 1200 meters. There was a fair
amount of DCAPE available, about 1500 J/kg.
Thunderstorms formed in three areas as the
afternoon progressed. One area was in
northwest Iowa, with the second over eastern
Nebraska moving into west central and
southwest Iowa. The third area was
smaller with development over the southeast
counties of the state. Initially the storms
produced some marginally severe half of three
quarter to one inch in diameter. As the
afternoon progressed, the two clusters in
northwest and southwest Iowa merged, and the
systems over the west took on more of a
storms over the southeast weakened. The
linear structure and the event transitioned
into a wind event. There were several reports
and power lines downed by the high winds. The
strongest winds was of trees measured at 75
MPH in Adair.

A very unstable airmass was in place over
Iowa during the afternoon of the 17th, though
it was also quite capped. The 700 mb
temperature was in the 14 to 15 C. range,
making it difficult for thunderstorm
activity to initiate. Plenty of moisture was
values in the 6000 to 8000 J/kg range based
on the surface, and near 5000 J/kg in the
mixed layer. Lifted indices fell to near -14
C. by the late afternoon as well. With the
exception of the surface, the lower levels
were fairly dry. The LCL was in excess of 2
100 meters by late afternoon. There was
plenty of potential for hail with -10 to -30
C layer CAPE in excess of 1000 J/kg, though
the freezing level was in excess of 15,500
feet. Low level lapse rates were in the 8 to
9 C. range in the zero to 3 km layer. The
shear environment was fairly favorable by
late afternoon with 30 to 40 kts of effective
shear. A cold front moved southeast across
the state during the afternoon. Ahead of it,
a hot and very moist airmass was in place.
Afternoon highs were in the mid 90s to around
100 with dew points in the mid to upper 70s.
Thunderstorms were not able to fire until the
late afternoon hours and only over the far
the storms did form, the mode of severe
weather was hail. Hail of golf ball, upwards
of 3 inch diameter fell in Black Hawk County
at Waterloo. The hail path began near the
airport and then tracked southeast through
downtown Waterloo, causing extensive damage.
Tama, Wapello, and Davis Counties were also
hit with large hail. Hail of nearly baseball
size pelted the countryside south of
Bloomfield. One brief tornado touched down
in Tama County near Tama. It touched down
in an open area just west of town and caused
little damage. During the afternoon hours,
temperatures in Des Moines reached 100
degrees for the first time since August of
2003. An 83 year old woman was overcome by
heat and found dead in her back yard around
1530 in the afternoon.

An extremely unstable and hot airmass was in
place over Iowa during the day on the 19th.
The weather situation was complicated with a
warm front extending from northwest into
central, into southeast Iowa during the mid
afternoon. Earlier in the day, and MCS moved
across north central into east central and
southeast Iowa. This MCS laid down an outflow
boundary that pushed southwest into the
state, and eventually met up with the warm
front. Along and southwest of the
boundary, considerable dew point pooling took
place. Afternoon temperatures reached the
upper 90s to near 105 with dew points in the
upper 70s to mid 80s. CAPE values soared to
the 8000 to 10,000 J/kg range by early
evening as the lifted index fell to the -10
to -15 C. range. A very strong cap was in
place with 700 mb temperatures warming
to between 14 and 17 C. The freezing level
was unusually high, in the 16,500 to 17,000
foot range. Thunderstorms tried to develop by
the early evening, but as additional warmer
and drier air pushed into the area the
dissipated. After sunset a cluster of
thunderstorms developed over southern
Minnesota and northern Iowa along the north
edge of the cap as a cold front pushed into
the state from the northwest. The shear
environment was quite favorable with shear in
the 55 to 70 kt range in the zero to 6 km
layer. The storms eventually developed into
an MCC and skirted the northern edge of IOWA,
Central Iowa. They produced strong winds and
some hail. The hail was limited by the very
warm airmass with reports of hail in the
penny to nickle size range. High winds caused
damage to trees and power lines with wind
speeds in the 60 to 70 MPH range with the
stronger storms in the Winnebago, Worth, and
Bremer County areas of north central and
northeast Iowa.

Iowa was between a quasi-stationary frontal
boundary to the north and a developing warm
front to the south. The airmass became quite
unstable as afternoon highs reached the upper
80s to mid 90s with dew point readings in the
low 70s. The lifted index fell to -7 C. by
late afternoon with CAPE of 3000 to 3500
J/kg. The LCL was fairly high in the 1000 to
2000 meter range. The airmass was very warm
with the freezing level around 15,300 feet.
Thunderstorms developed over central and
southeast Iowa during the late afternoon
hours and continued into the evening. The
shear environment was reasonably favorable
with 30 to 40 kts of shear in the zero to 3
km layer. The storms produced spotty high
winds and hail of up to an inch in diameter.
Trees were downed as well as 2 power poles in
Poweshiek County. In addition, a machine shed
was also lifted a foot off of the ground. In
Mahaska County, high winds ripped the siding
off of a house west of Leighton. The storms
produced heavy rainfall with precipitable
water values around 2 inches. Rainfall of 1
to 3 inches occurred with the heavier storms
in a period of an hour or so.

The airmass remained quite unstable across
Iowa as the night progressed. Thunderstorms
developed north of the southern boundary
mentioned above, as the low level jet
increased. Though most of the storms were not
severe, a small area of severe storms
developed in Union County. Four farmsteads
suffered wind damage as the storms moved
through. Trees were downed by the high winds
with damage at one house placed at $10,000,
and $5,000 at another due to trees falling on
the houses. Crop damage occurred as a result
of half inch diameter hail that fell along
with the winds.

An upper level disturbance initiated two
supercell thunderstorms in a moist to near
tropical atmosphere that was ahead of a cold
front in eastern Iowa. Outflow from the
supercells developed a broken line of of
storms that moved through Iowa and into
Illinois and Missouri. The line produced
sporatic pulse severe storms from east
central Iowa into northwest Illinois. The
more solid part of the line produced a
considerable amount of severe weather from
east central Iowa into northern Missouri.

From July 16-20, a deadly heat wave gripped
much of central, south-central and southeast
Kansas. Broad high pressure in the mid and
upper levels of the atmosphere caused
temperatures to soar into the 105-110 degree
range, with afternoon heat indices about the
same. The cover of darkness provided little
in the way of relief, as overnight
temperatures were slow to fall off, reaching
only the upper 70s by sunrise for some
locations. Unfortunately, the prolonged heat
claimed five lives across south-central
and southeast Kansas, most of them elderly
men. Three occurred in Wichita, one in Iola,
and another in Coffeyville. The heat
unofficially claimed three other lives, two
in Wichita and one in Coffeyville.
Additionally, dozens of individuals across
central, south-central and southeast Kansas
were treated for heat-related illnesses.

Two large wildfires burned out of control for
several hours across portions of Ellsworth
and Lincoln Counties on Sunday, July 30th.
The first blaze started late Sunday afternoon
in Ellsworth County, just north 1-70 between
mile markers 207 and 208. Southerly winds
of 35 mph rapidly spread the fire north into
southwest Lincoln County, where it raged out
of control and did the majority of its
damage. One family had to be evacuated from
their home. As this fire continued to spread,
a second blaze ignited a few hours later
just north of Sylvan Grove, near the junction
of highways 181 and 18. Both blazes were
eventually brought under control, and were
finally extinguished by early Monday morning,
but not before consuming over 1,000 acres of
grassland. Utility poles, trees and fence
lines were destroyed, but no major
structures were lost. Fortunately,
no injuries or deaths occurred.

Elkhart County
Countywide Flash Flood
Thunderstorms continued to develop and move
from west to east for several hours across
mainly the southern part of Elkhart County.
While many locations saw 2 to 4 inches of
rain, which did cause some localized urban
issues, a narrow band of much heavier rain set
up from Wakarusa east into Millersburg. By the
end of the event an off duty NWS employee
reported 8.17 inches in his gauge with another
employee only a few miles south of him
reporting 4.50 inches and spotters
reporting 6.65 inches west of Goshen. The
heavy rainfall resulted in many roads in this
narrow band being closed as water flowed over
them for several hours. Some roads had minor
washouts with extensive erosion along many of
the ditch banks. At least 24 businesses in
Elkhart suffered damage with a few of these
having to suspend operations until the water
could recede and clean up commence. Damage
was reported approaching 1.5 million dollars,
assessed from a combination of actual property
loss, as well as loss production and
income. Luckily, no evacuations were needed,
but there were some rescues of people from
vehicles that became stranded in the flood
waters. This included a police car along State
Route 119.

Lagrange County
Countywide Flash Flood
The same storms that affected southern Elkhart
county moved across parts of southern
Lagrange county, from Topeka to Oliver
Lake. Topaka was the hardest hit area with at
least 22 homes reporting some sort of damage
from the flash flood. Numerous roads were
flooded and closed in and around Topeka. 9
inches of rain was recorded in the Oliver
Lake area before tapering off after 3 am
EDT. Numerous streams that feed into the lake
and rainfall over the lake itself resulted in
the lake level rising 0.70 inches over the
normal stage at the DNR dam. Water covered
many of the piers with some boats floating on
shore or into other craft. Also several
roads around the lake had water flowing over
them. One structure sustained water damage on
the lake. Damage is estimated at $400.000.

A cold front dropped southeast across the
state during the day on the 1st into the
evening hours. By midnight...the front
extended east-northeast to west-southwest
across southern Iowa. The soundings
indicated a considerable amount of dry air
in the low levels, thus preventing the
formation of tornadoes. The LCL was in the
5500 to 6000 foot range during the event.
High temperatures warmed into the upper
80s over far northwest Iowa, to the 95 to
100 degree range over the south. Dew points
were generally in the upper 50s to mid 60s
except along the frontal boundary. Moisture
pooled along the boundary with dew points
rising into the low 70s. The atmosphere
became quiet unstable with lifted indices
around -9 C. and CAPE values in the 3500
to 4500 J/kg range. There was some shear
available, but it wasn't all that strong.
Generally shear in the zero to 3 km layer
was in the 25 to 30 kt range. The freezing
level was quite high, being in the 14,500
to 15,000 foot range. Thunderstorms fired
initially just to the north of the boundary
in northwest and north central Iowa, along
the north edge of the mid level cap. The
storm development was enhanced as a jet
speed max raced across southern North Dakota
into Wisconsin during the late afternoon,
putting Iowa in the 3rd quadrant, or right
entrance region, of the jet. These storms
produced three quarter to one inch diameter
hail in a few areas. The largest hail
occurred in the Clear Lake area and was the
size of half dollars. Gusty winds were also
reported, however most were in the 35 to 50
MPH range. One wind gust to around 60 MPH
downed tree limbs in Humboldt County at
Bradgate. As the evening progressed, an
outflow boundary from the convection in the
north pushed south into central Iowa.
Scattered thunderstorms developed along the
boundary, but most were not severe. One storm
produced a 62 MPH wind gust as it passed over
Grimes in Polk County. The storm had formed
along the outflow boundary, but weakened
quickly as the outflow boundary undercut the
storm. Thunderstorms continued to fire during
the night to the north of the actual frontal
boundary. These were quite elevated. One of
the storms became severe briefly and dropped
one inch diameter hail southeast of Boxholm
in Boone County.

A nearly stationary front extended northeast
to southwest across the state. An outflow
boundary was in place from previous
convection and extended from low pressure in
Kansas, across northern Missouri, into
northern Illinois. The airmass remained
fairly unstable with temperatures north of
the outflow boundary in the 80s and dew
points near 70. Sufficient heating took place
over Missouri south of the outflow boundary
to erode the CIN that was in place. CAPE
values reached 2000 to 4000 J/kg by the late
afternoon with lifted indices around -6 C.
Thunderstorms formed in the vicinity of the
outflow boundary and drifted northeast. There
was some shear in place with zero to 3 km
shear in the 25 to 35 kt range. The storms
became severe with several reports of three
quarter to one inch diameter hail received.
One of the storms produced high winds west of
Blockton in Taylor County. The freezing level
was quite high, limiting the hail size
somewhat as it was in the 13,500 to 14,100
foot range. As was the case the previous day,
there was considerable dry air in the lower
levels. As a result, the LCL was in the 1200
to 1400 meter range and limited the potential
for tornadic development.

The frontal boundary that had been across
Iowa the past few days remained stationary
across the state during the afternoon. Two
other weather features interacted with the
airmass during the late afternoon hours.
One was a mesoscale convective vorticity
maximum that moved from southern Nebraska,
east toward Iowa. A strong upper level trough
of low pressure dropped southeast out of
Canada, along with its associated cold
frontal boundary, into Iowa late in the day.
The airmass became very unstable by late
afternoon with high temperatures in the mid
to upper 80s and dew point temperatures in
low 70s. Lifted indices dropped to the -7 to
-12 C. range with CAPE values in the 3500 to
5500 J/kg range. The freezing level was quite
high int he 13,800 to 14,600 foot range,
limiting the hail size in spite of the CAPE
of 300 to 500 J/kg in the -10 C. to -30 C.
layer. The tornado theat was limited by the
LCL height being in the 800 to 1600 meter
range. Thunderstorms developed in western
Iowa initially with a few severe storms
reported. Some of the initial thunderstorms
produced high winds with 20 inch diameter
tree branches broken off in Humboldt County
at Livermore. As the late afternoon and
evening progressed, a line of thunderstorms
formed along the cold frontal boundary. Shear
in the 30 to 40 kt range helped maintain the
storms. There were reports of quarter size
hail from some of the cells. Wind became more
of an issue later in the event. Along the
line that formed along the northern cold
front, winds gusted to 61 MPH in the Fort
Dodge area and winds near 60 MPH west of
town. The winds caused an accident on U.S.
Highway 20 near Moorland. As the storms
progressed southeast, strong winds moved
through the Des Moines metro area.
Railroad crossing arms were broken by the
high wind in Des Moines. Farther southeast,
near Hartford, wind gusts were estimated
around 65 MPH by an off duty NWS employee.
Franklin County
2 SE Popejoy Flash Flood
An upper level low pressure system lifted
northeast into the central U.S. out of the
Monsoonal flow in the southwest U.S. The low
was slow moving as it advanced across the
area. A considerable amount of moisture was
drawn north ahead of the system with
precipitable water values in the 1.75 to 2.25
inch range. As the low advanced northeast,
a large area of rain and embedded
thunderstorms developed. The system took on
characteristics of a cool season system with
a large deformation zone forming along the
north edge of the system. With the deep
moisture in place, copious amounts of rain
fell in a narrow band, about 30 miles wide,
extended east of Omaha to north of Waterloo.
Rainfall amounts of 2 to 5 inches were common
in this area. The heaviest rain fell north of
Des Moines at Popejoy in Franklin County.
Official rainfall totals from the area were
around 8 inches, with some unofficial amounts
as high as a little over 9.5 inches. Radar
estimates show that between 3 and 5 inches of
the rain fell in the hour between 0500 and
0600 CST. The heavy rain caused flash
flooding southeast of Popejoy with several
county roads being closed by high water
flowing over the road.

A weak frontal boundary extending from
northwest Minnesota into southwest Kansas
advanced toward Iowa. The flow was very week,
but the airmass was very moist. Precipitable
water values were above 2 inches with a deep
warm layer in place. The freezing level was
between 14,500 and 15,500 feet. The CAPE in
the -10 to -30 layer was significant at
800 J/kg, but in spite of that there was
little hail due to the very high freezing
level. Afternoon temperatures warmed in to
the upper 80s to low 90s with dew points in
the mid 70s. This pushed the most unstable
CAPE to around 5500 J/kg. Lifted indices were
in the -9 to -11 range by late afternoon.
Tornadoes did not occur with a weak
shear environment (under 20 kts) and with an
LCL of 1000 to 1200 meters. There was a fair
amount of DCAPE available, about 1500 J/kg.
Thunderstorms formed in three areas as the
afternoon progressed. One area was in
northwest Iowa, with the second over eastern
Nebraska moving into west central and
southwest Iowa. The third area was
smaller with development over the southeast
counties of the state. Initially the storms
produced some marginally severe half of three
quarter to one inch in diameter. As the
afternoon progressed, the two clusters in
northwest and southwest Iowa merged, and the
systems over the west took on more of a
storms over the southeast weakened. The
linear structure and the event transitioned
into a wind event. There were several reports
and power lines downed by the high winds. The
strongest winds was of trees measured at 75
MPH in Adair.

A very unstable airmass was in place over
Iowa during the afternoon of the 17th, though
it was also quite capped. The 700 mb
temperature was in the 14 to 15 C. range,
making it difficult for thunderstorm
activity to initiate. Plenty of moisture was
values in the 6000 to 8000 J/kg range based
on the surface, and near 5000 J/kg in the
mixed layer. Lifted indices fell to near -14
C. by the late afternoon as well. With the
exception of the surface, the lower levels
were fairly dry. The LCL was in excess of 2
100 meters by late afternoon. There was
plenty of potential for hail with -10 to -30
C layer CAPE in excess of 1000 J/kg, though
the freezing level was in excess of 15,500
feet. Low level lapse rates were in the 8 to
9 C. range in the zero to 3 km layer. The
shear environment was fairly favorable by
late afternoon with 30 to 40 kts of effective
shear. A cold front moved southeast across
the state during the afternoon. Ahead of it,
a hot and very moist airmass was in place.
Afternoon highs were in the mid 90s to around
100 with dew points in the mid to upper 70s.
Thunderstorms were not able to fire until the
late afternoon hours and only over the far
the storms did form, the mode of severe
weather was hail. Hail of golf ball, upwards
of 3 inch diameter fell in Black Hawk County
at Waterloo. The hail path began near the
airport and then tracked southeast through
downtown Waterloo, causing extensive damage.
Tama, Wapello, and Davis Counties were also
hit with large hail. Hail of nearly baseball
size pelted the countryside south of
Bloomfield. One brief tornado touched down
in Tama County near Tama. It touched down
in an open area just west of town and caused
little damage. During the afternoon hours,
temperatures in Des Moines reached 100
degrees for the first time since August of
2003. An 83 year old woman was overcome by
heat and found dead in her back yard around
1530 in the afternoon.

An extremely unstable and hot airmass was in
place over Iowa during the day on the 19th.
The weather situation was complicated with a
warm front extending from northwest into
central, into southeast Iowa during the mid
afternoon. Earlier in the day, and MCS moved
across north central into east central and
southeast Iowa. This MCS laid down an outflow
boundary that pushed southwest into the
state, and eventually met up with the warm
front. Along and southwest of the
boundary, considerable dew point pooling took
place. Afternoon temperatures reached the
upper 90s to near 105 with dew points in the
upper 70s to mid 80s. CAPE values soared to
the 8000 to 10,000 J/kg range by early
evening as the lifted index fell to the -10
to -15 C. range. A very strong cap was in
place with 700 mb temperatures warming
to between 14 and 17 C. The freezing level
was unusually high, in the 16,500 to 17,000
foot range. Thunderstorms tried to develop by
the early evening, but as additional warmer
and drier air pushed into the area the
dissipated. After sunset a cluster of
thunderstorms developed over southern
Minnesota and northern Iowa along the north
edge of the cap as a cold front pushed into
the state from the northwest. The shear
environment was quite favorable with shear in
the 55 to 70 kt range in the zero to 6 km
layer. The storms eventually developed into
an MCC and skirted the northern edge of IOWA,
Central Iowa. They produced strong winds and
some hail. The hail was limited by the very
warm airmass with reports of hail in the
penny to nickle size range. High winds caused
damage to trees and power lines with wind
speeds in the 60 to 70 MPH range with the
stronger storms in the Winnebago, Worth, and
Bremer County areas of north central and
northeast Iowa.

Iowa was between a quasi-stationary frontal
boundary to the north and a developing warm
front to the south. The airmass became quite
unstable as afternoon highs reached the upper
80s to mid 90s with dew point readings in the
low 70s. The lifted index fell to -7 C. by
late afternoon with CAPE of 3000 to 3500
J/kg. The LCL was fairly high in the 1000 to
2000 meter range. The airmass was very warm
with the freezing level around 15,300 feet.
Thunderstorms developed over central and
southeast Iowa during the late afternoon
hours and continued into the evening. The
shear environment was reasonably favorable
with 30 to 40 kts of shear in the zero to 3
km layer. The storms produced spotty high
winds and hail of up to an inch in diameter.
Trees were downed as well as 2 power poles in
Poweshiek County. In addition, a machine shed
was also lifted a foot off of the ground. In
Mahaska County, high winds ripped the siding
off of a house west of Leighton. The storms
produced heavy rainfall with precipitable
water values around 2 inches. Rainfall of 1
to 3 inches occurred with the heavier storms
in a period of an hour or so.
Union County
2 NE Creston Thunderstorm Wind (G61)
The airmass remained quite unstable across
Iowa as the night progressed. Thunderstorms
developed north of the southern boundary
mentioned above, as the low level jet
increased. Though most of the storms were not
severe, a small area of severe storms
developed in Union County. Four farmsteads
suffered wind damage as the storms moved
through. Trees were downed by the high winds
with damage at one house placed at $10,000,
and $5,000 at another due to trees falling on
the houses. Crop damage occurred as a result
of half inch diameter hail that fell along
with the winds.

Heat
From July 16-20, a deadly heat wave gripped
much of central, south-central and southeast
Kansas. Broad high pressure in the mid and
upper levels of the atmosphere caused
temperatures to soar into the 105-110 degree
range, with afternoon heat indices about the
same. The cover of darkness provided little
in the way of relief, as overnight
temperatures were slow to fall off, reaching
only the upper 70s by sunrise for some
locations. Unfortunately, the prolonged heat
claimed five lives across south-central
and southeast Kansas, most of them elderly
men. Three occurred in Wichita, one in Iola,
and another in Coffeyville. The heat

Wildfire
Two large wildfires burned out of control for
several hours across portions of Ellsworth
and Lincoln Counties on Sunday, July 30th.
The first blaze started late Sunday afternoon
in Ellsworth County, just north 1-70 between
mile markers 207 and 208. Southerly winds
of 35 mph rapidly spread the fire north into
southwest Lincoln County, where it raged out
of control and did the majority of its
damage. One family had to be evacuated from
their home. As this fire continued to spread,
a second blaze ignited a few hours later
just north of Sylvan Grove, near the junction
of highways 181 and 18. Both blazes were
eventually brought under control, and were
finally extinguished by early Monday morning,
but not before consuming over 1,000 acres of
grassland. Utility poles, trees and fence
lines were destroyed, but no major
structures were lost. Fortunately,
no injuries or deaths occurred.
