With lots of sun today & not much wind, highs will run 36-42 today, followed by 20s, then rising into the 30s tonight with southerly wind.
A significant snowstorm will occur Iowa to northern Indiana tomorrow with intense frontagenetical forcing with Alberta Clipper there. We will be on the warm side of the clipper with sun, some clouds, windy conditions and highs 53-60.
It will turn cloudy tomorrow night & that will continue into Saturday. A dry cold front will pass, keeping us largely in the 40s for much of the day. Very cold air over the +12″ snow pack over Iowa and northern Illinois will bleed into our northwestern counties Saturday and then over a good 2/3 of the area Saturday night-Sunday morning. This said, some cold rain will overspread the area behind the front. As temperatures fall to 29-38 over the area Saturday-Saturday night, some freezing rain will occur with potential of some minor icing over about northwestern 2/3 of the Tri-State.
This will be short-lived as 50s return next week. Rain, some t’storms & 50s, 60s are possible late next week.
Latter February looks to return to a colder-than-normal pattern with the potential of some wintry precip before we rebound nicely as we end the month.
