Snow will continue throughout the evening hours and overnight. Snowfall accumulations will be about 3-5" for most areas, although some slightly higher totals are possible near the I-55 corridor and some slightly lower totals are possible northwest of the Illinois River.
Travel conditions will be hazardous this evening due to slick roads and reduced visibility, and then blowing/drifting snow will create additional hazards tomorrow morning as winds pick up overnight.
We'll see temperatures tomorrow morning in the 20s, but they'll drop into the teens by the afternoon. With gusty winds continuing, wind chills tomorrow afternoon may be close to 0. Friday will likely be the coldest day so far this winter with lows near -5 and highs in the low to mid teens. Wind chill values Friday morning will be -10 to -20, or possibly even lower at times.
Thankfully our cold snap is short and we'll be back closer to 40 this weekend. A few light snow showers are possible late Saturday, but otherwise expect quiet weather this weekend. Additional rain and snow showers are possible early next week, and then expect more cold air to return by the middle of the week.
Tonight: Snow likely. Total accumulations near 3-5".
Tomorrow: A few lingering snow showers, mainly early. Turning colder and breezy.
Friday: Sunny and cold.
