There is a thin layer of ice & some snow that has occurred in the area this morning to midday. We have a thin glaze & trace of sleet here at our WLFI observation site. I currently have freezing drizzle & 31 at our WLFI site. The Purdue Airport has 31 with freezing drizzle & visibility of 1.25 miles.

I am surprised we have not seen Newton, Jasper. Pulaski counties go under Winter Storm Watch yet.
Spotty to patchy light freezing rain, sleet, rain & snow are possible at times this afternoon-tonight. Highs will run 32-36 with lows 29-32.
Snow, sleet to sleet & freezing rain will overspread the area Monday morning after 8 a.m. It will reach the entire viewing area by afternoon.
A changeover to rain is still possible south of Indiana 18, but it may remain largely freezing rain, sleet & snow north of 18.
Winds will increase from the east Monday with gusts to 35 mph by late afternoon-evening.
Highs will run 31-37 northwest to southeast.
Blue is snow, pink/purple is freezing rain, rust color is sleet & green is rain with this loop around 8 a.m. Monday to 1 a.m. Tuesday:
By 1 a.m. early Tuesday morning, note the up to 4" snow in northern Newton, Jasper & Pulaski counties.
South of 18, 1" or less of snow is expected. Between 18 & 14, totals will gradually taper.
Note the band of heavier snow in southern Indiana expected tonight, which I don't doubt. We saw a similar situation south of us this morning. If that shifts northward, then totals will be higher in our southern counties.
There are a lot of moving parts with this system with multiple of waves of different types of precipitation, so there is a degree of some uncertainty given the fact any small shift in the track will result in a different duration of certain precipitation types or a certain band of heavier precipitation type.
Some of the moving parts include: 1) exact track which could mean a big different with just 30-40 miles difference 2) degree & timing of warm air begin lofted aloft 3) thickness of warm layer coming in aloft 4) degree & timing of the cold air aloft coming in
By Tuesday 1 a.m., up to 0.10" of glaze is expected with up to 0.1" of sleet, especially between Indiana 18 & US 24.
Although there is a trend to decrease glaze amounts a bit in the north, I would still like to keep mention of a couple isolated power outages & few limbs down given the windy weather & still even up to 0.10" of glaze.
Overnight Monday night-Tuesday AM may have some east to northeast wind gusts as high as 42 mph. Icy mix over the area will change to snow as temperatures drop into the 20s.
Total snow fall should run up to 6" along the Kankakee River & 0.7-2" south of 18. North of 18, 1.5-3" seems more likely (& again highest totals along the Kankakee River).
The strong winds will blow this snow around with the +40 mph gusts, so it will be very difficult to measure.
Any snow will exit late Tuesday morning.
Highs Tuesday should run 27-32 with north-northeast winds decreasing to 15-25 mph.
Heaviest snowfall with Wednesday night-Thursday AM system is showing a trend to set-up more south of our area.
However, we are still looking at accumulation with heavier amounts in our southern counties. Again, heaviest accumulations with the storm are showing a trend to set up south of our area.
We will monitor.
Big warmth is ahead in early February with taste of spring. Near/record warmth is still possible with showers & storms possible & even some severe weather risk.
Cold & ice risk will arrive in mid-February after the warmth & stormy weather. It looks to return in late February, however.
