Wintry mix returns Monday night

 

A wintry mix of rain and snow will return to northern Illinois and southern Wisconsin late Monday night, posing *some impacts to the commute Tuesday morning. The Stateline saw plenty of dense fog early Monday morning as temperatures fell into the low 30s. This did create a few slick and icy patches, mostly on elevated and untreated surfaces. The dense fog did dissipate but left skies mostly cloudy in its wake. Temperatures, while still above the average high of 31 degrees, were a bit cooler than the last several days. Areas of fog are possible again tonight.

Radar is beginning to look a bit more active as low pressure moves into Missouri. With plenty of dry air near the surface across northern Illinois and southern Wisconsin it'll take some time before we begin to see what is showing up on radar, actually reach the surface. But by late this evening a mix of rain and snow can be expected. For some, the precipitation will begin as light rain but will soon mix in with snow during the night. A transition over to all snow may occur, with some accumulations possible south of the state line, mainly on grassy and elevated surfaces.

Winds turn to the northwest Tuesday gusting 25-30 mph during the afternoon. High temperatures will warm into the mid-30s. A few weaker disturbances will move across the Midwest Tuesday afternoon and evening keeping the chance for scattered snow flurries, or light snow showers, through the evening.

As the ball drops to end 2024 and begin 2025 temperatures will be brisk in the mid-20s. If we do see scattered snow flurries/showers through the night, there may be some slick conditions for the drive home from your New Year's celebrations.
