It is rough out there tonight with wind chills already as low as -13 with gusts to 37 mph. Snow showers & flurries are exiting after dusting/coating of snow.
Wind chills as low as -25 to -20 will occur tomorrow morning with lows near -3.
Highs will reach 7-12 in the afternoon with lots of sun early, followed by increasing clouds. Wind chills will remain below zero all day.
We should hit our high temperature for tomorrow after dusk in the teens & should peak 19-24 tomorrow night. We will then fall back to the teens by Saturday morning.
Saturday looks mostly cloudy & breezy with temperatures slowly falling to 14 by later in the day with winds chills near 0.
Wave of snow pass later tomorrow evening-night to very early Saturday morning. Timing is 5 p.m. to 6 a.m.
1" or less is expected for a good chunk of the area. However, it does appear that there is the potential for a band of 1-2" to occur. It is a bit unclear where that is going to occur.
At this juncture, it looks like that 1-2" band may occur From Fowler & Pine Village to Greater Lafayette area to Frankfort. Some +2" amounts will occur in central Illinois.
Watch for slick roads Saturday morning & the powdery snow being blown & drifted about.
A wave of snow should pass Saturday evening-night to early Sunday morning.
At this point, it looks as if the 1-2" totals will run southwest & south of the viewing area with less than 1" here. However, we need to watch & make sure the higher totals do not move northward. They still could.
After teens Saturday, highs will run in the 20s.
Another wave of snow is possible Sunday evening-night with a quick 1" or less.
Monday-Monday night is the time when a much stronger clipper will pass. A band of intense frontagenetical forcing will occur with this system. It is unclear where this band will set up. Where this sets up, significant snowfall could occur. Whether that band is over our area or just over part of it (north or south or middle) or well north & northeast of us toward northern Illinois to Michigan is unclear.
Some snowfall accumulation snowfall is likely, with potential of a changeover to some ice in part of the area. If it gets warm enough, a brief spurt of some rain could occur in the southwestern part of the area. More questions than answers with this system, but know that the potential is there for that accumulating snow & mix, rain & strong, gusty winds to 40 mph.
Brutal, record cold is expected Wednesday-Thursday of next week with actual air temperatures as low as -23 in the viewing area & wind chills as low as -45 to -40.
Temperatures will rapidly moderate to teens by Friday with snowfall from another clipper system with gusty winds.
