Overview
Preliminary observed snowfall map from the morning of February 1 through the morning of February 4
A long-duration winter storm brought a mixed bag of rain, freezing rain, sleet, and heavy snow to central and southeast Illinois between February 1-3. This paired with winds gusting up to 30-35 mph created blowing/drifting snow, which resulted in dangerous travel conditions. The highest snowfall totals ranged from 8-15" within a swath situated between the Illinois River and I-70. Daily snowfall records were broken at our climate sites in Peoria, Springfield, and Lincoln on February 2. Lesser yet still significant snowfall amounts were reported elsewhere. Ice amounts were brief for most, with the largest accumulations situated south of I-72 where one to three tenths of an inch were reported prior to the heavy snowfall.

| Radar imagery showing the transition from rain to wintry mix and then finally snow across northwest portions of the forecast area on the evening of Tuesday February 1. | Correlation coefficient from the KILX radar showing the distinctive line between snow, mixed wintry precipitation, and rain during the late evening of Feb 1. | February 2, 6 AM CST KILX weather balloon sounding from our office here in Lincoln, IL. This sounding reveals a deeply saturated layer all the way up to nearly 200 mb with all levels below 0 degrees Celsius. A good portion of this layer is situated in the dendritic growth zone, which supported snowflake development that morning. Strong winds in the upper levels of the atmosphere were signs of a strong jet, which assisted in synoptic scale lift for widespread precipitation. |
A strong cold front moved through the area on Tuesday February 1, stalling out near the I-70 corridor by the evening hours. Rain started falling ahead of the front Tuesday morning and continued into the early evening hours as the front moved toward I-70. An upper wave lifting north along the front Tuesday night into Wednesday morning paired with a coupled upper-level jet created plentiful lift and steep mid-level lapse rates. This resulted in a ripe environment for efficient snow production. Cold air filtered in on the backside of the cold front on Tuesday night and transitioned rain to a wintry mix, and then eventually snow from northwest to southeast. By the morning hours of Wednesday, February 2 several inches of snow had fallen mainly along and north of I-72, with light ice accumulations along and south of I-72. Precipitation remained mostly rain south of I-70. Additional snow fell through the morning and afternoon hours on Wednesday, February 2 before a brief lull in precipitation occurred by evening. By 6 PM CST on Wednesday, February 2, 10.6” had been observed in Peoria with 8.7” in Lincoln and 7.9” in Springfield.
The front remained stalled out near I-70 Wednesday night as a second upper wave tracked northward along it, bringing our next round of precipitation late in the night. Additional snow fell mainly along and east of I-55 going into Thursday, February 3, with a wintry mix well south of I-70 to start. Areas south of I-70 finally switched to snow by mid-morning on Thursday, continuing into the evening hours. Snow totals when all said and done at our 3 climate sites were as follows: 10.6" in Peoria, 12" in Springfield, and 11" in Lincoln.
Records set at our 3 climate sites (Peoria, Springfield, & Lincoln):
