Flash Freeze main weather issue Thursday night
WINTER WEATHER ADVISORY is in effect until 6am Friday for Champaign, Christian, Clark, Coles, Cumberland, De Witt, Douglas, Edgar, Effingham, Fayette, Ford, Greene, Iroquois, Logan, Macon, Macoupin, Montgomery, Moultrie, Piatt, Sangamon, Shelby, and Vermilion counties.
A very strong cold front which passed through this afternoon is causing temperatures to free fall this evening. After highs in the 60s, temperatures are approaching the teens tonight. Rainfall as well as a wintry mix of precipitation will primarily cause either a light glaze of ice or a flash freeze from the rain that fell earlier today. With this being said, icy roads will be the main concern tonight especially for all surfaces that have been left untreated.
FLASH FREEZE: Thursday's rainfall hasn't dried up and with temperatures well below freezing tonight, into the teens, excess water will freeze over into black ice on untreated surfaces. Even some major highways and interstates may have slick spots tonight, particularly on bridges and overpasses.
SNOW: Locations in east central Illinois, near Champaign, Charleston, Danville, and Paris could see 1-2" of snow overnight tonight and early Friday morning. All other central Illinois locations will be much less than 1" if anything at all.
FREEZING RAIN: Most central Illinois communities may see a quick freezing rain shower or freezing drizzle tonight amounting to around .01-.03" of ice accumulations, but this will likely be overlooked by the flash freezing water which will add more to the overall icy conditions.
TRAVEL: Untreated roads, like most side streets and county roads will be slippery or icy tonight. Bridges and overpasses may have icy spots as well. We're expecting conditions to improve slightly during the morning hours Friday.
