High pressure across the St. Lawrence
Valley locked in cold air across
southern New England and combined with
low pressure south of the coast to
produce a significant snowfall. Snow
fell at rates of up to two inches per
hour for an eight to ten hour period
resulting in nearly a foot of snow in
most locations. Many motorists were
affected as early dismissals from
work and school just before snow
began created rush hour like
conditions which limited the
snowplows' ability to plow.

The latter half of December saw a
transition to a wetter pattern across
the southeast. Most observing stations
in the Upstate and northwest Piedmont
of South Carolina reported above normal
monthly rainfall for the first time
since January 2007. However, this was
not enough to put much of a dent in the
long-term drought as extreme to
exceptional drought conditions
persisted into the New Year. Despite
the wet end to the year, portions of
Upstate South Carolina experienced the
driest year on record. Although the
increase in rainfall did allow for some
recharge of area streams, most were
still running at less than 25 percent
of normal flow at the end of the month.
Lake Hartwell recorded the 3rd lowest
December average pool level on record.

Low pressure developed off the coast of
South Carolina and Georgia as a potent
upper level disturbance moved across
the region. Moderate to heavy rains
fell across the area, bringing much
needed rainfall to some drought
stricken areas. The pressure gradient
between the area of low pressure and
a wedge of high pressure across the
piedmont of South Carolina and Georgia,
associated with strong cold air
damming, produced strong winds along
the coast.

Drought conditions continued in
December over the eastern part
of Middle Tennessee. The City of
Crossville continued water
restrictions despite recent rains.
TVA projected that during the next
30 years, water demand will grow
more than 16 percent.
Mr. Doug Murphy, executive director
of the Duck River Agency that
represents Maury, Hickman, Marshall,
Bedford and Coffee Counties and
provides water for about 250,000
customers, said Normandy Lake will
have enough water to supply customers
until about July in 2008, unless the
weather conditions improve to
alleviate the drought.
The USDA's National Agricultural
Statistics Service, Tennessee Field
Office, stated that all crops showed
significant declines in yields from
the previous year. Corn yields were
down 19 bushels from last year, and
21 bushels below the 5-year average.
Soybean yields were less than half
of the 2006 crop yield, and was the
lowest yield since 1983. Burley tobacco
acreage was down to near record low
levels. Hay production was at 2.44
million tons, which was down 43
percent from 2006 crop. Alfalfa
production was down 43 percent
from 2006.

reported.
A very dynamic storm system brought a
variety of severe weather impacts to
the South Plains of west Texas late on
the 27th.
Moist and sub-freezing upslope
northeasterly flow behind a cold front
resulted in persistent ice fog through
much of the day over the extreme
southeastern Texas Panhandle,
particularly along the Caprock
Escarpment. Although ice accumulated
on most exposed surfaces, no adverse
impacts were reported.
By late afternoon, weather impacts
became much more intense and diverse.
An area of heavy snow developed over
the extreme southwestern Texas
Panhandle and the northwestern South
Plains. The area of wintry
precipitation quickly moved
northeastward, but not before
accumulating snows occurred over the
area and resulted in treacherous
travel conditions. Roadways,
including major interstate highways,
became snowpacked--and remained
dangerous through much of the morning
hours on the 28th.
Reported snow accumulations follow: 4
inches at Happy (Swisher County), 3
inches at Lazbuddie (farmer County),
3 inches at Tulia (Swisher County),
2 inches at Nazareth (Castro County),
1 inch at Dimmitt (Castro County), 1
inch at Plainview (Hale County), and
1 inch at Silverton (Briscoe County).
South of the snow band, strong winds
advected eastward behind a dryline-
like feature that moved over the
western and central South Plains.
Wind gusts in excess of 40 mph were
recorded at a number of Texas Tech
University West Texas Mesonet sites
over the western South Plains. Wind
contributed to the failure of a metal
shed building in northwest Lubbock.
In addition, two non-mesocyclonic
tornadoes were observed and
photographed in the Lubbock vicinity.
These tornadoes developed near a
deepening surface low and its
associated surface boundaries, and
beneath towering cumulus clouds within
a strongly unstable low-level airmass.
No measurable precipitation occurred
in association with the tornadic
cumuliform clouds.

A powerful ice storm affected parts of
western north Texas beginning on the
9th and continuing through the 10th.
A cold front with below freezing
temperatures moved through area during
the morning hours of the 9th. At the
same time, showers and thunderstorms
were developing as a strong upper level
storm system moved toward the area. The
thunderstorms moving over sub-freezing
air resulted in slick spots on bridges
and other elevated surfaces. Also, tree
limbs were downed as they could not
support the weight of the ice
accumulation. The freezing line pushed
north into southern Oklahoma late in
the day on the 10th. No accidents were
reported on area roadways.

A surface low moved across northern New
York and Vermont during the morning of
December 3rd. Snow overspread Vermont
during the late afternoon and early
evening hours of December 2nd and
changed to a mixture of snow, sleet and
freezing rain during the morning hours
of the 3rd before tapering to snow
showers by midday. However, a secondary
area of low pressure developed across
southeast Massachusetts during the
morning of the 3rd and moved into the
Gulf of Maine during the afternoon and
evening. This allowed the redevelopment
of accumulating snow across Vermont by
mid to late afternoon and continued
until just after midnight on December
4th.
Widespread snowfall accumulations were
6 to 12 inches across Vermont with
localized higher amounts in favored
upslope regions of the western slopes
of the Green Mountains and higher
elevations of northern Vermont. Some
of the higher snowfall totals included;
16 inches in Jerusalem (eastern Addison
county), 14 inches in South Lincoln
(eastern Addison county), Jay (Orleans

A powerful primary upper level and
surface low across the Ohio River
Valley on the morning of December
16th spawned a secondary coastal
low in the Delmarva Peninsula. Both
systems merged across southern New
England during the afternoon of the
16th and then moved into the Gulf

Snow overspread Vermont just after
midnight on the 16th and briefly
mixed with sleet during the late
morning and early afternoon hours
before steadier and heavier snow
returned during the late afternoon
hours and continued until just after
midnight on the 17th. Brisk northwest
winds of 15 to 25 mph with stronger
gusts accompanied the steadier
snowfall in the evening hours and
that resulted in considerable blowing
and drifting of the snow with greatly
reduced visibilities.
Storm total snowfall accumulations
across Vermont were 8 to 18 inches.
Some of the higher snowfall totals
included; 18 inches in Vergennes
(Addison county), Brookfield (Orange

A powerful upper level and surface
storm system across the Great Lakes
on December 23rd moved across Ontario
and Quebec during the 24th.
Accompanying this system were strong
winds in excess of 70 to 80 mph
between 3000 and 6000 feet above the
surface. Meanwhile, at the surface, a
strong warm and cold front associated
with this powerful storm moved across
Vermont during the evening hours of
the 23rd. The development of rain
showers along the cold front during
the evening hours allowed for some of
these strong winds to reach the surface
which caused localized wind damage in
the form of downed branches, trees and
scattered power outages as well as
damaged loose holiday lawn ornaments
in Cambridge (Lamoille county),
Montgomery (eastern Franklin county)
as well as Jay, Irasburg and Coventry
(Orleans county). In addition, there
was an unofficial anenometer reading

The latter half of December saw a
transition to a wetter pattern across

in the Upstate and northwest Piedmont
of South Carolina reported above normal
monthly rainfall for the first time
since January 2007. However, this was
not enough to put much of a dent in the
long-term drought as extreme to
exceptional drought conditions
persisted into the New Year. Despite
the wet end to the year, portions of
Upstate South Carolina experienced the
driest year on record. Although the
increase in rainfall did allow for some
recharge of area streams, most were
still running at less than 25 percent
of normal flow at the end of the month.

evening hours of December 2nd and
changed to a mixture of snow, sleet and
freezing rain during the morning hours
of the 3rd before tapering to snow
showers by midday. However, a secondary
area of low pressure developed across
southeast Massachusetts during the
morning of the 3rd and moved into the
Gulf of Maine during the afternoon and
evening. This allowed the redevelopment
of accumulating snow across Vermont by
mid to late afternoon and continued
until just after midnight on December
4th.
Widespread snowfall accumulations were
6 to 12 inches across Vermont with
localized higher amounts in favored
upslope regions of the western slopes
of the Green Mountains and higher
elevations of northern Vermont. Some
of the higher snowfall totals included;
16 inches in Jerusalem (eastern Addison
county), 14 inches in South Lincoln
(eastern Addison county), Jay (Orleans

Winter Storm
A powerful primary upper level and
surface low across the Ohio River
Valley on the morning of December
16th spawned a secondary coastal
low in the Delmarva Peninsula. Both
systems merged across southern New
England during the afternoon of the
16th and then moved into the Gulf
of Maine at night.
Snow overspread Vermont just after
midnight on the 16th and briefly
mixed with sleet during the late
morning and early afternoon hours
before steadier and heavier snow
returned during the late afternoon
hours and continued until just after
midnight on the 17th. Brisk northwest
winds of 15 to 25 mph with stronger
gusts accompanied the steadier
snowfall in the evening hours and
that resulted in considerable blowing
and drifting of the snow with greatly
reduced visibilities.
Storm total snowfall accumulations
across Vermont were 8 to 18 inches.
Some of the higher snowfall totals
included; 18 inches in Vergennes
(Addison county), Brookfield (Orange

strong warm and cold front associated
with this powerful storm moved across
Vermont during the evening hours of
the 23rd. The development of rain
showers along the cold front during
the evening hours allowed for some of
these strong winds to reach the surface
which caused localized wind damage in
the form of downed branches, trees and
scattered power outages as well as
damaged loose holiday lawn ornaments
in Cambridge (Lamoille county),
Montgomery (eastern Franklin county)
as well as Jay, Irasburg and Coventry
(Orleans county). In addition, there
