Springfield, IL – Roads across central Illinois could turn slick late Sunday night as rain rapidly changes to snow behind a powerful cold front, followed by dangerously cold wind chills dropping below zero by Monday night.
According to the National Weather Service in Lincoln, a strengthening low-pressure system will push a cold front across Illinois Sunday night. Rain during the day Sunday will transition to snow during the evening and overnight hours as temperatures quickly fall.
Cities including Peoria, Bloomington, Decatur, Champaign, and Springfield have a 50–80 percent chance of seeing at least 2 inches of snow by Monday morning, with the highest probabilities across western and northwestern portions of central Illinois.
The bigger impact may arrive after the snow ends. Strong northwest winds behind the system will push wind chills down into the -5°F to -10°F range Monday night, especially across Galesburg, Peoria, and Bloomington.
Wind chills near or below zero can develop quickly on exposed skin, and icy roads may linger into the Monday morning commute along Interstate 55, Interstate 72, and Interstate 74.
Residents should prepare for rapidly changing temperatures, dress in layers, and limit time outdoors Monday night as the coldest air of the system settles across the region. Additional advisories may be issued as the cold front approaches.
