Multiple storm systems brought several rounds of accumulating snow to Central Illinois between February 4th and February 11th. Snowfall amounts were highest along I-80 while less snow fell across southern portions of the region.
From February 2nd to February 11th, at least a trace of snow was reported in Peoria while measurable snow fell on six of those days. The bulk of the snow came with two separate storm systems, one that brought a quick 4-10 inches of snow to the region on Monday, February 5th and another that brought heavy snow to northern portions of the region on Friday, February 9th.
February 4th - February 7th
The first round of accumulating snow came with a quick, but powerful storm system that produced heavy snow over much of Central Illinois. The storm produced snowfall rates exceeding 1 inch per hour along and north of I-74 during the evening commute. Snow began in the afternoon and had stopped falling by midnight, at which point parts of Knox, Stark and Marshall counties had received 8-10 inches of snow. Peoria received 4.2 inches of snow, most of which came in a four hour period. This set a new daily snowfall record for February 5th. Another period light snow would move through the night of February 6th which left areas west of the Illinois River with another 1-2 inches of snow.
February 8th - February 9th
The second round of heavy snow came Thursday night and continued through the day on Friday. This storm mainly impacted areas north of I-74 with the heaviest snow falling along I-80 where 6-10 inches of snow had fallen. Snowfall amounts were expected to taper off quickly towards I-74 which is exactly what happened. A narrow band of snow brought 3 inches of snow to Princeville and Chillicothe while Peoria only saw a dusting. The storm prompted Winter Storm Warnings and Winter Weather Advisories across northern portions of the region.
Saturday, February 10th - Sunday, February 11th
A third and final storm system would then bring a round of lighter but more widespread snow to Central Illinois on the night of February 10th. The storm system was expected to produce a widespread 2-4 inches of snow across Central Illinois, impacting many areas who hadn't received much snow since the beginning of the week. By Saturday morning, snowfall amounts were adjusted down to 1-3 inches with locally higher amounts possible across northern portions of the region as the storm track had shifted a little further north. The storm would go on to produce 1-3 inches with higher amounts seen north of a Galesburg to Odell Line. The storm also produced periods of freezing rain and sleet across southern McLean and Tazewell Counties.
