Some areas are going to go from 60 today to single digits with wind chill near -10 tomorrow night with iced-up roadways.
Again......very much like last year when we saw 8 days with at least a trace of snow in November at WLFI with a total of 2.9" for the month.
The Purdue Ag Farm had a monthly total of 3.4".
This, followed by much warmer weather & MARGINAL RISK of severe weather at the very end of November 2018!
BIG CHANGE is ahead.....................
Temperatures are mild with not too much wind as of noon with 46-56 from northwest to south over the area.
However, old front will move southward & temperatures will fall to 30-37 north to south tonight with some light rain/drizzle, rain/snow to snow moving in from north to south late tonight & into tomorrow morning.
Precipitation should move into the north by 6 a.m. & overspread the area through tomorrow morning.
Main snowfall time frame is around noon & through afternoon.
It should become more scattered lake effect snow showers & flurries in the evening & into the early overnight.
Temperatures should fall into the 20s with time tomorrow with north to northwest winds gusting 30-40 mph at times with sustained winds at 15-25 mph. So, wind chills will tank well down into the teens.
Tomorrow night, with some clearing (through lake effect cloudiness with some flurries possible east & northeast), lows will drop to 8-17 with wind chills -10 to 1.
Highs Tuesday will only run 20-25 (more clouds in east & northeast with a few lake effect snow showers & flurries). Winds will be rather strong in the morning, then diminish.
The trend tonight to tomorrow evening:
Worst of the road conditions correspond with the heavier snow & lower temperatures with the strong winds.
This overlapping of all of these factors would be 1-8 p.m.
However, with the cold & wind tomorrow night, blowing & drifting snow will still be an issue & roads will still be pretty slippery (especially bridges & overpasses & lesser-traveled roadways).
Looks like around 1" to as much as 2" of snowfall for much of the viewing area.
Some isolated areas in the far north & also the far east/southeast may see more than 2" of snowfall.
A couple of waves of some snow showers are possible Wednesday-Wednesday night with 1" or less of accumulation possible.
It will be windy with temperatures in the 30s falling into the 20s, then teens Wednesday night.
After decreasing wind & 30s Thursday, it should turn windy & much warmer Friday through Sunday with 40s Friday & 50s by next weekend.
