THE FIRST ROUND OF ARCTIC AIR HAS ARRIVED.
SPRINGFIELD (WICS) - By far, the air mass that has settled into central Illinois today will be the coldest we've experienced so far this season. Wind chills have dipped into the single digits while air temperatures are at or just below 20 degrees. Although skies will be sunny, winds will continue to be brisk, gusting up to 25mph at times. Thus wind chills during the day will be no better than 12° which air temps sit in the mid 20s. Friday remains cold as well, although wind will die down a bit. morning lows will be in the mid teens with wind chills in the single digits, and highs in the mid 20s with wind chills in the upper teens.
This weekend has a lot of question marks and uncertainties regarding the potential for active weather and snowfall. A developing weather system in the central plains tracking into the Great Lakes area by Saturday, pushing snowfall north of a warm front. Models have trended further north with this as of late meaning that the heaviest snows will either be in northern Illinois or even Wisconsin. I'll keep a chance for light snow in the forecast late Saturday and in the evening hours, but it's possible this could miss us. Models have depicted a secondary wave trailing in the first's wake, but further south along the trailing cold front. This feature was a bit more aggressive with widespread snowfall across much of the state. So far, I won't put too much weight on higher snow totals, but between this two features, a little snow is likely at some point this weekend. It's also possible a little rain could mix in Sunday as temperatures rise to the mid 30s.
... Again a lot of question marks exist, but it's fair to assume that more accumulating snow will fall upstate, and that we'll see some kind of precipitation this weekend as a whole.
As for next week, yet another and even more powerful arctic wave is forecasted. The cold front passage Tuesday could bring light snow showers and flurries to the area, and temps as of now are forecasted in the teens for highs, and single digit low temps.
