Highs today ran 32-37 with a brisk south to south-southeast wind & gradual increase in high/mid clouds.
Snow should arrive in our western counties early Thursday morning by 6 a.m.
It should then overspread the area through morning before changing to rain from south to north.
The far northwestern areas will be the last to change to rain.
Temperatures will warm from 31-32 to 34-36.
Less than 1" is likely for much of the area before the change-over to rain.
However, 1" to perhaps a bit more than 1" could occur along & northwest of an Ambia to Earl Park to Rensselaer to Francesville line.
We will monitor for any slight deviations in projections snow.
Looks like all rain Thursday night through Friday with brisk southeast to east-southeast wind as deepening low tracks through southeastern Illinois.
It will be miserable outside with cold, icy rain, temperatures steady at 35-36 & wind chills in the 20s with those breezes at 10-25 mph.
Accumulating snowfall will continue from southern Wisconsin through northwestern & western Illinois to Missouri.
Rain should transition back to snow Friday late afternoon-evening as winds diminish.
Temperatures should cool from 35-36 to 32-33.
Snow is likely Friday night into part of Saturday with winds picking up from the northwest with time.
Totals Friday evening-Saturday still look to end up at around 1" to as much as 2" for much of the area with potential of some +2" amounts in our far northwest.
It will be a wet, gloppy snow with temperatures 31-32 Friday night.
Saturday's highs of 34-36 will melt snow.
It system would track just a bit more to the southeast, we would see much more.
We are going to pump out 0.60-1.30" of liquid from this system.
If it were all snow, it would be up to 13", given a 10:1 ratio.
Sunday just looks to feature a few flurries/sprinkles & highs 34-37, followed by a few spotty rain/snow showers Monday with highs 35-40 (after morning lows at 29-32).
Rain is likely late Tuesday through Wednesday with 40-45, followed by a change-over to snow Thursday as temperatures fall into the 20s.
Much colder air will surge in after that with lows dropping to the single digits.
