Temperatures will continue to warm into mid-week, bringing a more normal range back to the Midwest. However, wintry weather returns during the second half of the work week. Expecting snow to begin Wednesday evening, overspreading the area throughout the night. With warming temps Thursday, a mix of precipitation will slide overhead through the morning before changing to rain in the afternoon. Cooler temps Thursday night will allow for snow to redevelop across the region, also bringing the chance for hazardous road conditions overnight. This pattern continues into Friday before the system finally slides out of the Midwest on Saturday.
Snow is expected to move into central Illinois Wednesday evening. Two primary rounds of snow are expected over the next few days, one from Wednesday night into Thursday morning, and the other Thursday night and Friday morning. Each of these may produce 1-2" in some areas, with locally higher amounts. During the afternoon hours Thursday and Friday, temperatures should warm enough to switch the precipitation to rain. Thus, the main impacts are expected during the morning drive times both days.
