1) Weather Related Emergency Events: February 1, 2011 – February 26, 2011
· 2/1-2/11: A major winter storm impacted almost the entire state of Illinois. Record or near record snowfall accumulations ranging from 10 to 18 inches…with isolated 20 inch totals were reported from Calhoun County through Springfield to Iroquois County and points to the north. Wind gusts of 50 to 70 mph created snow drifts more than 7 feet high. Hundreds of motorists were stranded and several interstates, state highways and county roads were closed. The powerful storm also produced 1 to 4 inches of sleet in parts of east central Illinois and ¼ to ¾ inch of ice and widespread power outages – roughly between I-70 and I-64. The Governor issued a disaster declaration nearly 24 hours prior to the onset of the storm.
NWS offices from Lincoln, Romeoville, Quad Cities and St. Louis – along with the Illinois State Climatologist have worked with IEMA and FEMA regarding official snow amounts and the establishment of new record snowfalls. The snowstorm/blizzard was the biggest snowstorm since January 1-3, 1999.
· 2/5/11: A weather disturbance tracked across southern Illinois, which produced 3 to 7 inches of snow south of I-70. The highest totals were around Breese and Mascoutah where 6 to 7 inches was reported.
· 2/24-25/11: A storm system tracking along the Ohio Valley produced moderate amounts of snow in west central Illinois – and heavy rain in southern Illinois. Snowfall totals ranged from 3 to 6 inches in much of central Illinois…with the highest amounts near 7 inches around Quincy. Rainfall totals ranged from 0.75” along I-70 to 2.50” in extreme southern Illinois near I-24.
· February 2011 weather (Courtesy of the Illinois State Climatologist and the Midwest Regional Climate Center):
Temperature: Temperatures through February 26th averaged near normal in most of central and southern Illinois, and 1 to 2 degrees below normal in northern Illinois. The coldest stretch of weather was from the 2nd to the 4th, and the 8th to the 10th when low temperatures dipped into the single digits and below zero in many locations. This was followed by record or near record warmth in the middle of the month.
Precipitation: Liquid precipitation averaged around 0.50” to 1.25” above normal in much of Illinois.
The heavy snow/blizzard of February 1-2 resulted in above normal snowfall for northern and central Illinois. This ranged from 16” above normal in extreme northeast Illinois…to 4-6” above normal in central Illinois. Only extreme southeast Illinois averaged normal to slightly below normal snowfall for the month.

The February 1-2, 2011, blizzard crossed through much of central and northern Illinois. By overlaying the snowfall map over the 2000 Census data using GIS software, we can estimate the number of people in Illinois affected by the storm. A rule of thumb in winter storms is that economic impacts become significant in areas with 6 inches or more of snow.
About 10.9 million Illinois residents were in areas with 6 inches or more of snow in the February 1-2 storm. Furthermore, about 9.8 million Illinois residents were in areas with 12 inches or more of snow. And about 1.5 million Illinois residents were in areas with 18 inches or more of snow.
Monday February 14th, the largest solar flare since December 2006 occurred. This event disrupted High Frequency (HF) radio communications and prompted a rerouting of air traffic near the poles. According to the NWS Space Weather Prediction Center (SWPC), three waves of energy merged into a single G1, or minor, geomagnetic storm.
