Thunderstorms moved across northeast
Wisconsin as a cold front pushed through the
area. Several large storms produced hail of 2
inches to 4 inches in diameter during the
afternoon and evening. Four inch diameter hail
was reported in Suring (Oconto co.) and
hailstones of just over 3 inches in diameter
were measured east of Oconto Falls (Oconto co.)
and near Branch (Manitowoc co.). An observer
found tennis ball size hail near Hayes (Oconto
co.) half an hour after the storms ended there.
Damage amounts listed in this report are
estimates. Gaint hail caused damage to more
than 700 vehicles, denting them and smashing
their windows. The hail damaged at least 800
homes, breaking windows, denting siding and
knocking chunks out of vinyl siding. Business
signs were smashed and foliage was stripped
from trees by the hail.
High winds from the storms downed trees from
Two Rivers (Manitowoc co.) to Manitowoc
(Manitowoc co.).

Below normal rainfall in most areas, along with
temperatures that averaged more than 3 degrees
above normal, resulted in the formation of
severe drought conditions in parts of north
central Wisconsin. The June 1st through July
31st precipitation deficit was 3.18 inches at
Wausau and 3.01 inches at Rhinelander.
The U.S. Drought Monitor indicated severe
drought (D2) in the western parts of Vilas,
Oneida and Lincoln counties for the last three
weeks of the month. Otherwise most of northeast
Wisconsin was in either the moderate drought
(D1) or abnormally dry (DO) category.

broken line of severe storms developed during
the evening hours of July 1st as a cold front
headed southeast through south-central and
southeast Wisconsin. The atmosphere became very
unstable during the afternoon as temperatures
reached the lower 90s with dew points in the
upper 60s. These storms produced large hail
(golf ball size near Marquette in Green Lake
Co.) and areas of wind damage as they headed
across Sauk, Marquette, Green Lake, Columbia,
and Fond du Lac counties. Primarily tree damage
was reported across these counties in addition
to a destroyed barn at a location 1 mile north

dissipating. No damage was reported from this
FO tornado. This tornado was most likely of the
landspout variety and the result of vertical
stretching of a low-level circulation into the
updraft of a towering cumulus cloud that formed
on a weak atmospheric boundary that was
moving south through Fond du Lac County. No
precipitation was observed on the WSR-88D
Doppler radar, and only very weak rotation was
noted on only one volume scan with a 6 ktl-6
kt speed differential in the 0.5 degree scan.

About 300 trees were damaged or detroyed by the
hail at a tree nusury 3 miles east of Ripon. A
broken line of severe storms developed during
the evening hours of July 1st as a cold front
headed southeast through south-central and
southeast Wisconsin. The atmosphere became very
unstable during the afternoon as temperatures
reached the lower 90s with dew points in the
upper 60s. These storms produced large hail
(golf ball size near Marquette in Green Lake
Co.) and areas of wind damage as they headed
across Sauk, Marquette, Green Lake, Columbia,
and Fond du Lac counties. Primarily tree damage
was reported across these counties in addition
to a destroyed barn at a location 1 mile north
of Rosendale (Fond du Lac Co.). Two reports of
funnel clouds were also noted; one being in
Berlin (Green Lake Co.) at 1820CST and the
other in Dundee (Fond du Lac Co.) at 1950CST.

dissipating. No damage was reported from this
FO tornado. This tornado was most likely of the
landspout variety and the result of vertical
stretching of a low-level circulation into the
updraft of a towering cumulus cloud that formed
on a weak atmospheric boundary that was
moving south through Fond du Lac County. No
precipitation was observed on the WSR-88D
Doppler radar, and only very weak rotation was
noted on only one volume scan with a 6 ktl-6
kt speed differential in the 0.5 degree scan.

A complicated weather scenario
developed during the late afternoon
and early evening of July 9th. A cold
front pushing east into southwestern
Wisconsin produced slow moving
scattered thunderstorms across
south-central Wisconsin as a lake
breeze pushed west into the counties
of Washington, eastern Waukesha and
Racine. This resulted in more slow
moving thunderstorms. Some of the
across south-central Wisconsin pulsed
to severe levels producing up to
half-dollar sized hail (1.25" in
diameter) and wind gusts to 52 knots
(60 mph). The storms over southeast
Wisconsin were just as strong.
however, those storms aligned
themselves along the northwest to
southeast oriented lake breeze as
they tracked very slowly southeast.
Additional storms continuously
developed on the northwest edge of
the line. This resulted in a prolonged
period of training storms and
torrential rain. Around 5 inches of
rain was estimated by WSR-88D Doppler
radar across northeast Waukesha County
and central Milwaukee County. Flash
flooding resulted near the cities of
Brookfield (Waukesha Co.), downtown
Milwaukee (Milwaukee Co.), West Allis
(Milwaukee Co.), and Kenosha (Kenosha
Co.)--mainly in the form of several
feet of water over roadways and soil
erosion.
Two days earlier, on July 7th, in
Milwaukee, a female, age 32, died from
high temperatures in her residence.
The maximum and minimum temperatures
for Milwaukee on July 7th were 81 and
61, respectively. Afternoon heat index
values on July 7th were in the lower
to mid 80s. These values are well
below threshold values of 105 needed to
generate a StormData event. Therefore,
this heat-related death will be
considered indirectly-related to heat.

Two rounds of severe storms affected
parts of south-central and southeast
Wisconsin on July 17th. The first
round occurred during the early
afternoon hours over the counties of
Dodge, Fond du Lac, Washington, and
Sheboygan. By 1250CST the storms had
organized into a bow echo line
extending from Lake Winnebago south to
near West Bend and Hartford in
Washington County and then west to
the Columbus area in southeastern
Columbia County. This bow echo then
moved east to out over Lake Michigan.
Dime-size hail and thunderstorm wind
gusts up to 65 knots (75 mph) resulted
with some of these storms. Tree and
power-line damage was reported in
addition to some structural damage in
Dodge and Sheboygan counties. A
semi-truck was also blown off
InterState 43. After a brief lull from
thunderstorms, more storms developed
during the evening hours across the
remainder of south-central and southest
Wisconsin. These storms produced dime
to quarter-sized hail and wind gusts
to around 52 knots (60 mph). Mainly
tree damage was reported with these
storms.
Interestingly, the cluster of severe
storms that affected the southern
parts of Lafayette and Green Counties
moved east-southeast to McHenry County
in northeastern Illinois. A strong
thunderstorm gust front (outflow
boundary), associated with the McHenry
County thunderstorms, pushed north
into southeastern Wisconsin. The gust
front winds knocked down some trees in
the Twin Lakes-Trevor area of western
Kenosha County, and the Eagle Lake
area northwest of Kansasville in
south-central Racine County.
No precipitation was associated with
these outflow winds in Kenosha and
Racine County. Eventually this gust
front merged with another south-moving
frontal boundary over the central
portions of Racine County. Severe
thunderstorms quickly popped up in this
merger zone over central Racine
County, and eventually they moved
southeast through the remainder of
Racine and Kenosha Counties (round #2
of severe weather for July 17th).
Synoptically, a strong, mid-level
short wave trough traveled east through
Wisconsin during the afternoon and
evening hours. Hot temperatures in the
mid-90s with dew points in the low to
mid-70s, and cooler air aloft, caused
extreme instability to increase
through the day which allowed for rapid
thunderstorm development.

Lightning struck a rural home and the
resultant fire burned the house to the
ground. During the pre-dawn early
morning hours of July 20th, a severe
squall line pushed into south-central
and southeast Wisconsin from southern
Minnesota. This squall line produced
mainly damaging winds, some reports
being "significant" (>65 knots or
hurricane-force), and only a couple
hail reports. One of the significant
reports was at a location 4 miles
northeast of Monona at 0140CST where a
gust of 71 knots (82 mph) was measured,
before the power went out. Hundreds of
trees were knocked down in the Madison
area, and there were dozens power-line
damage reports. Up to 40,000 customers
lost electrical power across southern
Wisconsin, with 13,000 alone in the
Madison area. The squall line weakened
as it approached the corner of
southeast Wisconsin due to weakening
instability, despite still favorable
deep layer shear. Toward dawn, more
scattered thunderstorms developed
across south-central Wisconsin as a
northwest to southeast axis of
instability redeveloped. A few of
these storms pulsed up to produce
only marginal severe hail and wind.

Widely scattered thunderstorms developed across
south-central and southeast Wisconsin during the
afternoon of July 22nd as convective inhibition
diminished. Cold air aloft and low freezing
levels made it easy for storms to produce large
hail and a few reports of damaging, straight-
line winds. Up to golf-ball sized hail was
noted. The storms diminished quickly as
instability subsided toward evening.
On July 22nd, a female, age 94, died due to
elevated temperatures in her residence in Monroe
(Green Co.). She was not using her air-
conditioner, Outside maximum and minimum air
temperatures on July 22nd in the Monroe area
were about 80 and 58, respectively. Afternoon
heat index values maxed out in the lower 80s,
well below official threshold values of 105
needed to generate a heat event in StormData.
Therefore, this heat-related death will be
considered as an indirectly-related heat death.
It is possible that the three hot days of July
15-17, with maximum air temperatures in the mid
90s and overnight lows of 70-75, may have
weakened the 94-year-old female
(pre-conditioned). Heat index values reached 95
to 100 on July 15th in the Monroe area.

Heavy rains of 4 to 5 inches fell over the area
just southwest and south of Paoli within 90
minutes, based on WSR-88D Doppler radar
estimates. There were no reports of flash
flooding that would result in property or crop
damage. However, some small streams in the area
probably flooded for a an hour or so, and then
receded. In addition, some low-lying roads
probably had some water on them. Refer to the
Madison flash flood event write-up to see a
rainfall graphic of Dane County for July
27th.

A composite of official rainfall amounts from
gage sites as well as WSR-88D Doppler radar
rainfall estimates. A 1-in-a-100-year flash
flood occurred from the west side of Madison
to around the Capitol Square after 3 to 5
inches of rain fell within a 90 minute
timeframe. There were no reports of injuries or
deaths. The heavy rain resulted from slow-moving
and back-building thunderstorms that essentially
remained nearly stationary over the city of
Madison. The hilly terrain and a typical urban
setting of a lot of concrete and asphalt enable
the runoff water to quickly overwhelm the storm
sewers and concentrate water in low-lying areas
of the city. Water depths reach to the top of
small vehicles--4 to 5 feet deep in spots. Many
roads became impassable due to the flood waters,
and many residential homes and businesses on or
near the UW-Madison campus had flooded basement
and first-floor flooding. Some basement
apartment units had water depths of 6 to 8 feet.
Nearly all campus buildings had flooding of
varying degrees of intensity, and the Camp
Randall football field sustained damage. Some
campus buildings had flat roofs that quickly
flooded as storm drains became plugged--which
allowed water to run thru the walls and ceilings
of buildings. The buildings that sustained the
most damage were the Memorial Union,
Computer Sciences, and Veterinary Medicine.
Numerous vehicles on or near the campus were
damaged or totaled by the flood waters, and some
were reported to be floating away. Unofficial
rain gages measured 4.5 to 5 inches from just
west of West High School up to the Capitol
Square. WSR-88D Doppler rainfall estimates were
in the 3 to 5 inch rain, therefore it appears
the unofficial rain gages were very accurate.
Rainfall amounts quickly fell off to 1 to 1.5
inches near the south Beltline (STH14/18/151).
It is nearly impossible to assess the monetary
value of the flash flood damage, therefore, the
amount posted in the header strip
of this event is only a ballpark estimate.

Composite rainfall graphic based on rainfall
amounts from official gage sites and WSR-88D
Doppler radar estimates. A 1-in-a-100-year
flood occurred in and around the city of
Waukesha after a heavy rain of 3 to 5 inches
within a 2-hr period. The heavy rains were
the result of slow-moving or back-building
thunderstorms that essentially sat over the
same area. There were no reports of injuries or
deaths. Numerous roads and yards were flooded
with water depths of 1 to 5 feet. Many vehicles
were stalled in the deep waters or were damaged.
There were numerous reports of flooded basements
comment of the downtown Waukesha Fire Department
flooded to the depth of 5 feet. This flooding
was the result of a collapsed trench outside
the building where a new addition was under
construction. At one point, Waukesha city
officials warned motorists to stay away from
the city, and some officials thought the July
27th flooding was the worst they could remember.
WSR-88D Doppler radar rainfall estimates
indicated that up to 5 inches fell over the
northwest portion of the city of Waukesha,
tapering off to 2 inches on the far south side
of the city where STH 59 is located. One
unofficial rain gage catch was 4.25 inches on
the north side of the city, which matched the
radar estimate. It is nearly impossible to
assess the monetary amount of the flash flood
damage, therefore, the amount posted in the
header strip of this event is only a rough
estimate.

A similar scenario to that of July 9, 2006
occurred again on the afternoon of July 27th.
Very slow moving scattered thunderstorms
developed across portions of south-central
and southeast Wisconsin. A lake breeze fired
additional storms across Waukesha County. With
propagation speeds often less than 15 mph,
torrential rains resulted underneath these
storms. Nearly stationary storms over the
Madison and Waukesha areas produced 4 to 5
inches of rain within about 90 minutes. Flash
flooding resulted in these locales with many
buildings and vehicles sustaining varying
degrees of damage. The UW-Madison campus was
especially hit hard. See the specific write-ups
as flash flood entries above. Other smaller
cities in Dane and Waukesha counties also
experienced some minor urban flooding, but
these reports did not warrant a separate
line-item entry above. Other storms across the
area pulsed to severe limits to produce damaging
winds to about 61 knots (70 mph) and one funnel
cloud report at 1228CST at a location 2 miles
northwest of Stoughton (Dane Co.). The major
electrical companies estimated that about 10,000
customers were without electrical power at one
time or another on July 27th, due to tree debris
or lightning striking power-lines.

Thunderstorms moved across northeast
Wisconsin as a cold front pushed through the
area. Several large storms produced hail of 2
inches to 4 inches in diameter during the
afternoon and evening. Four inch diameter hail
was reported in Suring (Oconto co.) and
hailstones of just over 3 inches in diameter
were measured east of Oconto Falls (Oconto co.)
and near Branch (Manitowoc co.). An observer
found tennis ball size hail near Hayes (Oconto
co.) half an hour after the storms ended there.
Damage amounts listed in this report are
estimates. Gaint hail caused damage to more
than 700 vehicles, denting them and smashing
their windows. The hail damaged at least 800
homes, breaking windows, denting siding and
knocking chunks out of vinyl siding. Business
signs were smashed and foliage was stripped
from trees by the hail.

Below normal rainfall in most areas, along with
temperatures that averaged more than 3 degrees
above normal, resulted in the formation of
severe drought conditions in parts of north
central Wisconsin. The June 1st through July
31st precipitation deficit was 3.18 inches at
Wausau and 3.01 inches at Rhinelander.
The U.S. Drought Monitor indicated severe
drought (D2) in the western parts of Vilas,

weeks of the month. Otherwise most of northeast
Wisconsin was in either the moderate drought
(D1) or abnormally dry (DO) category.

to severe levels producing up to
half-dollar sized hail (1.25" in
diameter) and wind gusts to 52 knots
(60 mph). The storms over southeast
Wisconsin were just as strong.
however, those storms aligned
themselves along the northwest to
southeast oriented lake breeze as
they tracked very slowly southeast.
Additional storms continuously
developed on the northwest edge of
the line. This resulted in a prolonged
period of training storms and
torrential rain. Around 5 inches of
rain was estimated by WSR-88D Doppler
radar across northeast Waukesha County
and central Milwaukee County. Flash
flooding resulted near the cities of
Brookfield (Waukesha Co.), downtown
Milwaukee (Milwaukee Co.), West Allis
(Milwaukee Co.), and Kenosha (Kenosha
Co.)--mainly in the form of several
feet of water over roadways and soil
erosion.
Two days earlier, on July 7th, in
Milwaukee, a female, age 32, died from
high temperatures in her residence.
The maximum and minimum temperatures
for Milwaukee on July 7th were 81 and
61, respectively. Afternoon heat index
values on July 7th were in the lower
to mid 80s. These values are well
below threshold values of 105 needed to
generate a StormData event. Therefore,
this heat-related death will be
considered indirectly-related to heat.

Two rounds of severe storms affected
parts of south-central and southeast
Wisconsin on July 17th. The first
round occurred during the early
afternoon hours over the counties of
Dodge, Fond du Lac, Washington, and
Sheboygan. By 1250CST the storms had
organized into a bow echo line
extending from Lake Winnebago south to
near West Bend and Hartford in
Washington County and then west to
the Columbus area in southeastern
Columbia County. This bow echo then
moved east to out over Lake Michigan.
Dime-size hail and thunderstorm wind
gusts up to 65 knots (75 mph) resulted
with some of these storms. Tree and
power-line damage was reported in
addition to some structural damage in
Dodge and Sheboygan counties. A
semi-truck was also blown off
InterState 43. After a brief lull from
thunderstorms, more storms developed
during the evening hours across the
remainder of south-central and southest
Wisconsin. These storms produced dime
to quarter-sized hail and wind gusts
to around 52 knots (60 mph). Mainly
tree damage was reported with these
storms.
Interestingly, the cluster of severe
storms that affected the southern
parts of Lafayette and Green Counties
moved east-southeast to McHenry County
in northeastern Illinois. A strong
thunderstorm gust front (outflow
boundary), associated with the McHenry
County thunderstorms, pushed north
into southeastern Wisconsin. The gust
front winds knocked down some trees in
the Twin Lakes-Trevor area of western
Kenosha County, and the Eagle Lake
area northwest of Kansasville in
south-central Racine County.
No precipitation was associated with
these outflow winds in Kenosha and
Racine County. Eventually this gust
front merged with another south-moving
frontal boundary over the central
portions of Racine County. Severe
thunderstorms quickly popped up in this
merger zone over central Racine
County, and eventually they moved
southeast through the remainder of
Racine and Kenosha Counties (round #2
of severe weather for July 17th).
Synoptically, a strong, mid-level
short wave trough traveled east through
Wisconsin during the afternoon and
evening hours. Hot temperatures in the
mid-90s with dew points in the low to
mid-70s, and cooler air aloft, caused
extreme instability to increase
through the day which allowed for rapid
thunderstorm development.

Lightning struck a rural home and the

ground. During the pre-dawn early
morning hours of July 20th, a severe
squall line pushed into south-central
and southeast Wisconsin from southern
Minnesota. This squall line produced
mainly damaging winds, some reports
being "significant" (>65 knots or
hurricane-force), and only a couple
hail reports. One of the significant
reports was at a location 4 miles
northeast of Monona at 0140CST where a
gust of 71 knots (82 mph) was measured,
before the power went out. Hundreds of
trees were knocked down in the Madison
area, and there were dozens power-line
damage reports. Up to 40,000 customers
lost electrical power across southern
Wisconsin, with 13,000 alone in the
Madison area. The squall line weakened
as it approached the corner of
southeast Wisconsin due to weakening
instability, despite still favorable
deep layer shear. Toward dawn, more
scattered thunderstorms developed
across south-central Wisconsin as a
northwest to southeast axis of
instability redeveloped. A few of
these storms pulsed up to produce
only marginal severe hail and wind.

Widely scattered thunderstorms developed across
south-central and southeast Wisconsin during the
afternoon of July 22nd as convective inhibition
diminished. Cold air aloft and low freezing
levels made it easy for storms to produce large
hail and a few reports of damaging, straight-
line winds. Up to golf-ball sized hail was
noted. The storms diminished quickly as
instability subsided toward evening.
On July 22nd, a female, age 94, died due to
elevated temperatures in her residence in Monroe
(Green Co.). She was not using her air-
conditioner, Outside maximum and minimum air
temperatures on July 22nd in the Monroe area
were about 80 and 58, respectively. Afternoon
heat index values maxed out in the lower 80s,
well below official threshold values of 105
needed to generate a heat event in StormData.
Therefore, this heat-related death will be
considered as an indirectly-related heat death.
It is possible that the three hot days of July
15-17, with maximum air temperatures in the mid
90s and overnight lows of 70-75, may have
weakened the 94-year-old female (pre-
conditioned). Heat index values reached 95 to
100 on July 15th in the Monroe area.

A composite of official rainfall amounts from
gage sites as well as WSR-88D Doppler radar
rainfall estimates.
A 1-in-a-100-year flash flood occurred from the
west side of Madison to around the Capitol
Square after 3 to 5 inches of rain fell within a
90 minute timeframe. There were no reports of
injuries or deaths. The heavy rain resulted from
slow-moving and back-building thunderstorms that
essentially remained nearly stationary over the
city of Madison. The hilly terrain and a typical
urban setting of a lot of concrete and asphalt
enable the runoff water to quickly overwhelm the
storm sewers and concentrate water in low-lying
areas of the city. Water depths reach to the top
of small vehicles--4 to 5 feet deep in spots.
Many roads became impassable due to the flood
waters, and many residential homes and
businesses on or near the UW-Madison campus had
flooded basement and first-floor flooding. Some
basement apartment units had water depths of 6
to 8 feet. Nearly all campus buildings had
flooding of varying degrees of intensity, and
the Camp Randall football field sustained
damage. Some campus buildings had flat
roofs that quickly flooded as storm drains
became plugged--which allowed water to run thru
the walls and ceilings of buildings. The
buildings that sustained the most damage were
the Memorial Union, Computer Sciences, and
Veterinary Medicine. Numerous vehicles on or
near the campus were damaged or totaled by the
flood waters, and some were reported to be
floating away. Unofficial rain gages measured
4.5 to 5 inches from just west of West High
School up to the Capitol Square. WSR-88D
Doppler rainfall estimates were in the 3 to 5
inch rain, therefore it appears the unofficial
rain gages were very accurate. Rainfall amounts
quickly fell off to 1 to 1.5 inches near the
south Beltline (STH14/18/151). It is nearly
impossible to assess the monetary value of the
flash flood damage, therefore, the amount posted
in the header strip of this event is only a
ballpark estimate.

Composite rainfall graphic based on rainfall
amounts from official gage sites and WSR-88D
Doppler radar estimates. A 1-in-a-100-year
flood occurred in and around the city of
Waukesha after a heavy rain of 3 to 5 inches
within a 2-hr period. The heavy rains were
the result of slow-moving or back-building
thunderstorms that essentially sat over the
same area. There were no reports of injuries or
deaths. Numerous roads and yards were flooded
with water depths of 1 to 5 feet. Many vehicles
were stalled in the deep waters or were damaged.
There were numerous reports of flooded basements
comment of the downtown Waukesha Fire Department
flooded to the depth of 5 feet. This flooding
was the result of a collapsed trench outside
the building where a new addition was under
construction. At one point, Waukesha city
officials warned motorists to stay away from
the city, and some officials thought the July
27th flooding was the worst they could remember.
WSR-88D Doppler radar rainfall estimates
indicated that up to 5 inches fell over the
northwest portion of the city of Waukesha,
tapering off to 2 inches on the far south side
of the city where STH 59 is located. One
unofficial rain gage catch was 4.25 inches on
the north side of the city, which matched the
radar estimate. It is nearly impossible to
assess the monetary amount of the flash flood
damage, therefore, the amount posted in the

A similar scenario to that of July 9, 2006
occurred again on the afternoon of July 27th.
Very slow moving scattered thunderstorms
developed across portions of south-central
and southeast Wisconsin. A lake breeze fired
additional storms across Waukesha County. With
propagation speeds often less than 15 mph,
torrential rains resulted underneath these
storms. Nearly stationary storms over the
Madison and Waukesha areas produced 4 to 5
inches of rain within about 90 minutes. Flash
flooding resulted in these locales with many
buildings and vehicles sustaining varying
degrees of damage. The UW-Madison campus was
especially hit hard. See the specific write-ups
as flash flood entries above. Other smaller
cities in Dane and Waukesha counties also
experienced some minor urban flooding, but
these reports did not warrant a separate
line-item entry above. Other storms across the
area pulsed to severe limits to produce damaging
winds to about 61 knots (70 mph) and one funnel
cloud report at 1228CST at a location 2 miles
northwest of Stoughton (Dane Co.). The major
electrical companies estimated that about 10,000
customers were without electrical power at one
time or another on July 27th, due to tree debris
or lightning striking power-lines.

the evening hours of July 1st as a cold front
headed southeast through south-central and
southeast Wisconsin. The atmosphere became very
unstable during the afternoon as temperatures
reached the lower 90s with dew points in the
upper 60s. These storms produced large hail
(golf ball size near Marquette in Green Lake
Co.) and areas of wind damage as they headed
across Sauk, Marquette, Green Lake, Columbia,
and Fond du Lac counties. Primarily tree damage
was reported across these counties in addition
to a destroyed barn at a location 1 mile north
of Rosendale (Fond du Lac Co.). Two reports of
funnel clouds were also noted; one being in

landspout variety and the result of vertical
stretching of a low-level circulation into the
updraft of a towering cumulus cloud that formed
on a weak atmospheric boundary that was
moving south through Fond du Lac County. No
precipitation was observed on the WSR-88D
Doppler radar, and only very weak rotation was
noted on only one volume scan with a 6 ktl-6

broken line of severe storms developed during
the evening hours of July 1st as a cold front
headed southeast through south-central and
southeast Wisconsin. The atmosphere became very
unstable during the afternoon as temperatures
reached the lower 90s with dew points in the
upper 60s. These storms produced large hail
(golf ball size near Marquette in Green Lake
Co.) and areas of wind damage as they headed
across Sauk, Marquette, Green Lake, Columbia,
and Fond du Lac counties. Primarily tree damage
was reported across these counties in addition
to a destroyed barn at a location 1 mile north
of Rosendale (Fond du Lac Co.). Two reports of
funnel clouds were also noted; one being in
Berlin (Green Lake Co.) at 1820CST and the
other in Dundee (Fond du Lac Co.) at 1950CST.

updraft of a towering cumulus cloud that formed
on a weak atmospheric boundary that was
moving south through Fond du Lac County. No
precipitation was observed on the WSR-88D
Doppler radar, and only very weak rotation was
noted on only one volume scan with a 6 ktl-6

A complicated weather scenario
developed during the late afternoon
and early evening of July 9th. A cold
front pushing east into southwestern
Wisconsin produced slow moving
scattered thunderstorms across
south-central Wisconsin as a lake
breeze pushed west into the counties
of Washington, eastern Waukesha and
Racine. This resulted in more slow
moving thunderstorms. Some of the
across south-central Wisconsin pulsed
to severe levels producing up to
half-dollar sized hail (1.25" in
diameter) and wind gusts to 52 knots
(60 mph). The storms over southeast
Wisconsin were just as strong.
however, those storms aligned
themselves along the northwest to
southeast oriented lake breeze as
they tracked very slowly southeast.
Additional storms continuously
developed on the northwest edge of
the line. This resulted in a prolonged
period of training storms and
torrential rain. Around 5 inches of
rain was estimated by WSR-88D Doppler
radar across northeast Waukesha County
and central Milwaukee County. Flash
flooding resulted near the cities of
Brookfield (Waukesha Co.), downtown
Milwaukee (Milwaukee Co.), West Allis
(Milwaukee Co.), and Kenosha (Kenosha
Co.)--mainly in the form of several
feet of water over roadways and soil
erosion.
Two days earlier, on July 7th, in
Milwaukee, a female, age 32, died from
high temperatures in her residence.
The maximum and minimum temperatures
for Milwaukee on July 7th were 81 and
61, respectively. Afternoon heat index
values on July 7th were in the lower
to mid 80s. These values are well
below threshold values of 105 needed to
generate a StormData event. Therefore,
this heat-related death will be
considered indirectly-related to heat.

Two rounds of severe storms affected
parts of south-central and southeast
Wisconsin on July 17th. The first
round occurred during the early
afternoon hours over the counties of
Dodge, Fond du Lac, Washington, and
Sheboygan. By 1250CST the storms had
organized into a bow echo line
extending from Lake Winnebago south to
near West Bend and Hartford in
Washington County and then west to
the Columbus area in southeastern
Columbia County. This bow echo then
moved east to out over Lake Michigan.
Dime-size hail and thunderstorm wind
gusts up to 65 knots (75 mph) resulted
with some of these storms. Tree and
power-line damage was reported in
addition to some structural damage in
Dodge and Sheboygan counties. A
semi-truck was also blown off
InterState 43. After a brief lull from
thunderstorms, more storms developed
during the evening hours across the
remainder of south-central and southest
Wisconsin. These storms produced dime
to quarter-sized hail and wind gusts
to around 52 knots (60 mph). Mainly
tree damage was reported with these
storms.
Interestingly, the cluster of severe
storms that affected the southern
parts of Lafayette and Green Counties
moved east-southeast to McHenry County
in northeastern Illinois. A strong
thunderstorm gust front (outflow
boundary), associated with the McHenry
County thunderstorms, pushed north
into southeastern Wisconsin. The gust
front winds knocked down some trees in
the Twin Lakes-Trevor area of western
Kenosha County, and the Eagle Lake
area northwest of Kansasville in
south-central Racine County.
No precipitation was associated with
these outflow winds in Kenosha and
Racine County. Eventually this gust
front merged with another south-moving
frontal boundary over the central
portions of Racine County. Severe
thunderstorms quickly popped up in this
merger zone over central Racine
County, and eventually they moved
southeast through the remainder of
Racine and Kenosha Counties (round #2
of severe weather for July 17th).
Synoptically, a strong, mid-level
short wave trough traveled east through
Wisconsin during the afternoon and
evening hours. Hot temperatures in the
mid-90s with dew points in the low to
mid-70s, and cooler air aloft, caused
extreme instability to increase
through the day which allowed for rapid
thunderstorm development.

l W Elmore Lightning
Lightning struck a rural home and the
resultant fire burned the house to the
ground. During the pre-dawn early
morning hours of July 20th, a severe
squall line pushed into south-central
and southeast Wisconsin from southern
Minnesota. This squall line produced
mainly damaging winds, some reports
being "significant" (>65 knots or
hurricane-force), and only a couple
hail reports. One of the significant
reports was at a location 4 miles
northeast of Monona at 0140CST where a
gust of 71 knots (82 mph) was measured,
before the power went out. Hundreds of
trees were knocked down in the Madison
area, and there were dozens power-line
damage reports. Up to 40,000 customers
lost electrical power across southern
Wisconsin, with 13,000 alone in the
Madison area. The squall line weakened
as it approached the corner of
southeast Wisconsin due to weakening
instability, despite still favorable
deep layer shear. Toward dawn, more
scattered thunderstorms developed
across south-central Wisconsin as a
northwest to southeast axis of
instability redeveloped. A few of
these storms pulsed up to produce
only marginal severe hail and wind.

2 SSE Milwaukee
Widely scattered thunderstorms developed across
south-central and southeast Wisconsin during the
afternoon of July 22nd as convective inhibition
diminished. Cold air aloft and low freezing
levels made it easy for storms to produce large
hail and a few reports of damaging, straight-
line winds. Up to golf-ball sized hail was
noted. The storms diminished quickly as
instability subsided toward
evening.
On July 22nd, a female, age 94, died due to
elevated temperatures in her residence in Monroe
(Green Co.). She was not using her air-
conditioner, Outside maximum and minimum air
temperatures on July 22nd in the Monroe area were
about 80 and 58, respectively. Afternoon heat
index values maxed out in the lower 80s, well
below official threshold values of 105 needed to
generate a heat event in StormData. Therefore,
this heat-related death will be considered as an
indirectly-related heat death. It is possible
that the three hot days of July 15-17, with
maximum air temperatures in the mid 90s and
overnight lows of 70-75, may have weakened the
94-year-old female (pre-conditioned). Heat
index values reached 95 to 100 on July 15th
in the Monroe area.
Racine County
Racine Lightning
Lightning struck the chimney of a home in the

only an estimate--all that is known is that the
lightning strike occurred during the morning
hours.

2 SW Paoli Heavy Rain
Heavy rains of 4 to 5 inches fell over the area
just southwest and south of Paoli within 90
minutes, based on WSR-88D Doppler radar
estimates. There were no reports of flash
flooding that would result in property or crop
damage. However, some small streams in the area
probably flooded for a an hour or so, and then
receded. In addition, some low-lying roads
probably had some water on them. Refer to the
Madison flash flood event write-up to see a
rainfall graphic of Dane County for July
27th.

6 W Madison to Flash Flood
2 NE Madison
A composite of official rainfall amounts from
gage sites as well as WSR-88D Doppler radar
rainfall estimates.
A 1-in-a-100-year flash flood occurred from the
west side of Madison to around the Capitol
Square after 3 to 5 inches of rain fell within a
90 minute timeframe. There were no reports of
injuries or deaths. The heavy rain resulted from
slow-moving and back-building thunderstorms that
essentially remained nearly stationary over the
city of Madison. The hilly terrain and a typical
urban setting of a lot of concrete and asphalt
enable the runoff water to quickly overwhelm the
storm sewers and concentrate water in low-lying
areas of the city. Water depths reach to the top
of small vehicles--4 to 5 feet deep in spots.
Many roads became impassable due to the flood
waters, and many residential homes and
businesses on or near the UW-Madison campus had
flooded basement and first-floor flooding. Some
basement apartment units had water depths of 6
to 8 feet. Nearly all campus buildings had
flooding of varying degrees of intensity, and
the Camp Randall football field sustained
damage. Some campus buildings had flat
roofs that quickly flooded as storm drains
became plugged--which allowed water to run thru
the walls and ceilings of buildings. The
buildings that sustained the most damage were
the Memorial Union, Computer Sciences, and
Veterinary Medicine. Numerous vehicles on or
near the campus were damaged or totaled by the
flood waters, and some were reported to be
floating away. Unofficial rain gages measured
4.5 to 5 inches from just west of West High
School up to the Capitol Square. WSR-88D
Doppler rainfall estimates were in the 3 to 5
inch rain, therefore it appears the unofficial
rain gages were very accurate. Rainfall amounts
quickly fell off to 1 to 1.5 inches near the
south Beltline (STH14/18/151). It is nearly
impossible to assess the monetary value of the
flash flood damage, therefore, the amount posted
in the header strip of this event is only a
ballpark estimate.

2 NW Waukesha to Flash Flood
6 SSE Waukesha
Composite rainfall graphic based on rainfall
amounts from official gage sites and WSR-88D
Doppler radar estimates. A 1-in-a-100-year
flood occurred in and around the city of
Waukesha after a heavy rain of 3 to 5 inches
within a 2-hr period. The heavy rains were
the result of slow-moving or back-building
thunderstorms that essentially sat over the
same area. There were no reports of injuries or
deaths. Numerous roads and yards were flooded
with water depths of 1 to 5 feet. Many vehicles
were stalled in the deep waters or were damaged.
There were numerous reports of flooded basements
comment of the downtown Waukesha Fire Department
flooded to the depth of 5 feet. This flooding
was the result of a collapsed trench outside
the building where a new addition was under
construction. At one point, Waukesha city
officials warned motorists to stay away from
the city, and some officials thought the July
27th flooding was the worst they could remember.
WSR-88D Doppler radar rainfall estimates
indicated that up to 5 inches fell over the
northwest portion of the city of Waukesha,
tapering off to 2 inches on the far south side
of the city where STH 59 is located. One
unofficial rain gage catch was 4.25 inches on
the north side of the city, which matched the
radar estimate. It is nearly impossible to
assess the monetary amount of the flash flood
damage, therefore, the amount posted in the
header strip of this event is only a rough
estimate.

A similar scenario to that of July 9, 2006
occurred again on the afternoon of July 27th.
Very slow moving scattered thunderstorms
developed across portions of south-central
and southeast Wisconsin. A lake breeze fired
additional storms across Waukesha County. With
propagation speeds often less than 15 mph,
torrential rains resulted underneath these
storms. Nearly stationary storms over the
Madison and Waukesha areas produced 4 to 5
inches of rain within about 90 minutes. Flash
flooding resulted in these locales with many
buildings and vehicles sustaining varying
degrees of damage. The UW-Madison campus was
especially hit hard. See the specific write-ups
as flash flood entries above. Other smaller
cities in Dane and Waukesha counties also
experienced some minor urban flooding, but
these reports did not warrant a separate
line-item entry above. Other storms across the
area pulsed to severe limits to produce damaging
winds to about 61 knots (70 mph) and one funnel
cloud report at 1228CST at a location 2 miles
northwest of Stoughton (Dane Co.). The major
electrical companies estimated that about 10,000
customers were without electrical power at one
time or another on July 27th, due to tree debris
or lightning striking power-lines.

time. These storms produced mainly damaging
winds up to 61 knots (70 mph), and some
isolated large hail. Vivid lightning was also
noted. Lightninghit a tree in Racine around
0910CST causing it to fall onto and lightly
damage a car. About 15,000 customers were
without electrical power due to tree damage
to power-lines.

Heat
A period of very hot and humid weather began
on the evening of July 30th and continued into
August 2nd. Overnight temperatures only fell to
70 to 75 on the 30th, and soared into the 95 to
100 degree range during the afternoon of July
31st. With dew points in the low to mid-70s,
heat index values only dropped to about 75
overnight on July 30th, and peaked in the 105
to 110 degree range across south-central and
southeast Wisconsin during the afternoon of
July 31st. An estimated 40 people in Milwaukee
County were hospitalized due to heat-related
symptoms. For information about the August
