JANUARY:

** Low pressure tracked from the southern Plains to southern Missouri and
then to the Ohio Valley on January 9-10. A frontal boundary draped across
eastern Iowa and northern Illinois focused a band of moderate to heavy snow.
Widespread accumulations of 5 to 9 inches were common in northeast Iowa and
northwest Illinois north of Interstate 80.

** A strong clipper storm system moved southeast from the Dakotas to southeast
Iowa and then into Illinois on January 13-14. The path of this area of low
pressure brought accumulating snow to portions of eastern Iowa and northwest
Illinois. Widespread snow amounts of 6 to 8 inches were noted along and north
of the Interstate 80 corridor.

** After the two heavy snow events of January 9-10 and January 13-14, snow
depths ranged from 4 inches at Burlington to 15 inches at Cedar Rapids. Widespread
snow depths of 6 to 12 inches were measured across eastern Iowa and northwest
Illinois. The deep snow cover set the stage for a strong surge of arctic air that
brought record minimum temperatures to the region on January 14-16. In fact, an
all-time record low temperature was established at Cedar Rapids, Iowa on January
15 when the mercury dropped to 29 below. All of eastern Iowa, northwest and west
central Illinois and extreme northeast Missouri experienced extreme cold. Actual
temperatures were as low as 20 to 40 below north of Highway 34 with 10 to 20 below
south of Highway 34, with wind chills to 30 to 50 below.



FEBRUARY:


** A strengthening low pressure system tracked from northern Kansas to central
Missouri and then into Illinois. Meanwhile, a strong upper level trough dove
southeast out of the northern Plains. The combination of these two features
produced areas of light to moderate snow, with brief heavy snow, across the region
on February 20-21. Three to six inches of snow was common in southeast Iowa, western
Illinois and extreme northeast Missouri, along and south of the Highway 34 corridor.
Another area of 3 to 5 inches fell in extreme northeast Iowa and northwest Illinois.
In addition to the snow, strong northwest winds gusting to 35 to 40 mph produced
areas of blowing and drifting. A 5-car pileup occurred on February 21 on snowy U.S.
Highway 61 north of Burlington that caused four indirect injuries.

** A few severe thunderstorms developed in the early afternoon hours across portions
of northeast Iowa and extreme northwest Illinois on February 26. A strong upper
level disturbance rotating across the region and an approaching cold front triggered
the storms. A few locations reported nickel to quarter size hail. In northeast Iowa,
near Keystone in Benton county, the hail completely covered the ground.



MARCH:

** An intense low pressure system in southwest Missouri tracked to northern Indiana
on March 28-29. This produced a band of heavy snow in portions of eastern Iowa, with
4 to 7 inches of accumulation common. The most snow observed was 7 inches in the Cedar
Rapids area.



APRIL:

** High level clouds were common across the area April 26, as a warm front lifted northward
to between Highways 30 and 20. Some heavy rain-producing showers and thunderstorms
developed during the late afternoon northwest of Highway 151. One produced large hail
and a tornado as it tracked from northern Linn County into southern Delaware County.



MAY:



JUNE:

** A stalled frontal boundary draped from the Iowa-Missouri border into Illinois resulted
in the development of showers and thunderstorms on June 1. After some peeks of sunshine
during the early afternoon, severe thunderstorms erupted mainly along and south of Highway
34, producing large hail and wind gusts over 58 mph. One lone storm in northern Stephenson
County produced some damaging winds and a tornado near Orangeville, IL. Heavy rains also
produced some flash flooding in Hancock County Illinois.



JULY:

** A cold front from Lake Superior across northwest Iowa coupled with an upper level
low over southwest Ontario with an associated short wave dropping across southern
Minnesota sparked the development of thunderstorms during the afternoon and evening
of July 24. Severe storms producing copious amounts of large hail up to the size of
a tennis ball and damaging wind gusts between 60 and 90 mph were common. An isolated
tornado touched down near Princeton, IL around 950 pm.


** Record Cold July



AUGUST:

** A heat burst struck parts of Cedar Rapids, IA between 528 am and 532 am August 3. A
61 mph wind gust was measured in downtown Cedar Rapids, while estimated wind gusts
ranged from 60 mph to over 70 mph. The temperature spiked up to 84 degrees at the KCRG
Studios while just south southeast of Cedar Rapids the temperature was observed to
have shot up to 77 degrees. Temperatures were in the upper 60s to around 70 prior to
the heat burst. Numerous trees and branches were blown down in the vicinity with power
outages observed on the northwest and southwest sides of the city.

** A cold front stretching across the upper Midwest, coupled with warm moist air streaming
northward across the area, brought scattered showers and isolated thunderstorms to
portions of east central Iowa and northern Illinois during the midday hours August 9.
Some locations along the Highway 20 corridor saw rainfall amounts ranging from 1 to 2
inches from these storms. Afternoon high temperatures were in the upper 80s to lower 90s.


By late afternoon, showers and thunderstorms began to redevelop along the cold front in
western Iowa and spread eastward into the Mid-Mississippi Valley.


During the evening hours, these storms brought widespread rain to the Mid-Mississippi
Valley. In addition, several of these storms became severe over eastern Iowa producing
winds gusts from 50 to 80 mph around the Cedar Rapids Area.

** Late morning and early afternoon sunshine was the fuel for a couple rounds of showers
and thunderstorms across the region August 19. The storms brought heavy rain to most areas,
with rainfall amounts between a half inch and an inch and a half common. In addition,
tornadoes were reported from central Illinois all the way up to the Twin Cities. This
included touchdowns near Stanley and Martelle, IA. With all of the cloud cover during
the afternoon, high temperatures only topped out in the upper 70s to lower 80s.

** A stationary front draped across the region continued to bring cloudy skies, along
with scattered showers and isolated thunderstorms to the Mid-Mississippi Valley
August 26. Rainfall totals ranged from three quarters of an inch up to 5 inches or more
in some locations. The torrential rainfall totals lead to some flash flooding across
parts of the area.
Cloudy skies along with scattered showers and thunderstorms continued across much of the 
area August 27. While most locations saw rainfall amounts ranging from a few tenths of
an inch up to 2 to 3 inches, a heavier band or rain fell from Cedar Rapids to Dubuque.
Amounts in this area ranged from 3 to 6 inches, causing many area roads to be closed
during the afternoon and evening due to flash flooding.

The 3-day rainfall totals for August 25-28 ranged from just under 2 1/2 inches to just
over 9 inches.

DECEMBER:

** A very intense storm system tracked from the Oklahoma Panhandle to western Illinois
and then to Lake Huron. This produced very heavy snowfall, blizzard conditions and bitterly
cold temperatures on December 8-9.  At least 10 inches of snow was reported north of a
Fairfield, Iowa to Sterling, Illinois line. The largest amount was a whopping 17.7 inches
at Orangeville, Illinois in Stephenson county.  Other amounts included 15 inches at Brighton,
Iowa (Washington county), Mt. Vernon, Iowa (Linn county) and at Freeport, Illinois
(Stephenson county).  Snowfall amounts were lighter in southeast Iowa, extreme northeast
Missouri and west central Illinois. Here snow accumulations were less than 3 inches as
rain and sleet mixed with the snow. A band of freezing rain from Burlington, Iowa to
Sterling, Illinois coated trees and power lines with up to 3 tenths of an inch of ice.

In addition, winds gusting over 50 mph produced widespread blizzard conditions across much
of eastern Iowa and northwest Illinois, reducing visibilities to near zero.

**  An ice storm occurred on December 23 in portions of eastern Iowa and northwest Illinois.
Ice accumulations of 1/4 to 1/2 inch coated trees and power lines but temperatures in the lower
30s kept most roads wet.  Scattered power outages and some broken tree branches were reported.

** A slow moving upper level low pressure system over the region produced a prolonged period
of light to moderate snow during the weekend of December 26-27.  Over the 2-day period snow
accumulations of 4 to 8 inches were common.
