Snow showers are possible in our far southern areas this late afternoon-evening. Otherwise, just some lake effect snow showers & flurries will occur this evening-tonight for the rest of the area.
Winds will be strong from the north at 15-30 mph.
Local dusting to coating is possible with 0.5" or less, but up to 1" may occur in northern Jasper to Pulaski counties. 1.5" is possible along the Kankakee River in Jasper County.
Watch for a few slick spots as low tonight drop into the 20-25 range after highs today at 28-34.
Strong surface high will calm conditions & inversion will result in a cold early Friday morning with heavy frost & some freezing fog possible.
We could really tank temperature-wise as long as lake effect cloudiness is not trapped under surface high & we can put down a coating of snow in places.
Single digits to teens are possible.
My thoughts turn to the coldest nights of the winter centering in mid-February now.
System over the weekend continue to show a tendency to track farther south.
Precipitation will likely begin as snow Saturday, transition to mix, then go to all rain Saturday night & into Sunday. It may end as a bit of snow Sunday afternoon as temperatures fall.
It does appear that accumulation of snow will occur at the onset, especially in our northeastern & northern counties with much less & sharp cut-off with southwestward extent.
It is a closer call for Greater Lafayette for accumulation, but a couple to a few inches could occur in our northeastern counties before changing to rain.
Stay tuned for further updates.
