With Tuesday system getting in slightly earlier, we may light freezing rain & sleet make it into our northwestern counties by noon. This, after gusty winds to 32 mph in the morning from the southeast with blowing & drifting snow largely on east-west roadways.
This light icy mix will gradually progress south & eastward.
The best potential of brief minor icing from freezing rain, sleet & even a few flakes would be along & north of a Covington to Attica to Lafayette to Peru line. Even with temperatures rising to 35 by 5 p.m. in the evening, there will still be some pavement at 30-32, so some patchy ice could still be on some roadways & elevated surfaces even then.
As the heavier precipitation overspreads the entire viewing area with time in the evening, it should turn to completely all rain Any brief icing prior should melt away. We should warm to 37-42 over the area just after midnight for our high temperature.
Rain may end as some snow Wednesday morning with some flurries & snow showers at times perhaps Wednesday afternoon-night.
Whether we see a quick inch or possible two or just a dusting will be determined by how quickly the cold air catches up with the deepest moisture Wednesday morning.
This is pretty significant rainfall atop frozen, snow- & ice-covered ground. We are looking at a good 0.50-1" Tuesday evening-night. This will create much ponding on roads & in lawns, etc. There will be a lot of water on secondary roads to freeze up Wednesday as temperatures fall from 20s to lower 30s in the morning to 18-25 by late afternoon. This, with some snow, will make for some slick spots/areas on some roadways.
Gusts tomorrow from the south-southeast to the south, then south-southwest will run up to 40 mph. Highs gusts look to arrive a hair later than first throught. Looks more like overnight than tomorrow evening. Gusts 40-50 mph are likely. A few gusts may reach 50-55 mph.
Gusts 40-45 mph at times may continue into Wednesday morning. Winds will diminish pretty quickly to gusts of 20-25 mph in the afternoon.
Three clippers may bring some accumulating snowfall Thursday, Saturday & Sunday night-Monday.
Bitterly cold weather with wind chills -25 to -20 are possible Friday morning.
