We'll see increasing cloud cover overnight with lows tomorrow near 20. Cloudy skies will continue throughout the day tomorrow, but gusty winds out of the south will help our temperatures climb into the mid to upper 30s by tomorrow afternoon.
A few light snow showers may be possible late tomorrow evening, especially west of the Illinois River, and then snow will become more widespread as we head into Wednesday night and Thursday morning. Temperatures will hover near freezing throughout the day on Thursday and Friday, which makes this forecast a tricky one. A few degrees will mean the difference between all snow and rain/sleet/freezing rain mixing in. So while snowfall amounts are still a little uncertain, accumulations of at least a few inches look like a good bet between Wednesday night and Friday night/Saturday morning.
All snow would mean higher amounts, possibly more than just a few inches, and mixing would lead to lower totals.
Dry weather returns early next week with highs rebounding to near 40 next Tuesday.
Tonight: Increasing clouds. Lows near 20.
Tomorrow: Mostly cloudy with a few late evening snow showers. Highs in the upper 30s.
Thursday: Snow, with possibly a wintry mix at times. Highs in the mid 30s.
