Saturday was a pleasantly cool day as temperatures finally cracked the 20-degree mark for the first time in over a week. Sunshine dominated the sky, making it feel warmer than the afternoon high of 24° would suggest. A continued clear sky overnight will drop out temperature back to the single digits before clouds slowly build in for Sunday morning.
Sunday will start on a cloudy note with temperatures back into the mid-20s by the afternoon. We will remain dry through at least the late morning, but a stray flurry may be possible as early as the afternoon. The evening will bring the best chance for some light but steady snow showers, finally working through the drier air above the surface.
Best coverage of any light snow will be centered between 6PM Sunday evening and 3AM Monday morning. Visibility may be limited down to a mile or less in the steadiest snow. A coating of snow may develop on roadways, causing some slick spots.
All told, most in the Stateline may be able to pick up around a half inch through Monday morning. A few locations in far NW Illinois may get slightly more than that, but 0.5" looks to be the cap for most of the area. This will be enough to coat untreated surfaces, so be cautious of slick spots beginning late Sunday evening!
