Wednesday Forecast Update

It's been a dry and chilly morning across northern Illinois and southern Wisconsin, as a low pressure system slows down over Iowa. We still have wintry weather in the forecast, but the timing has slowed down.


Most of northern Illinois and southern Wisconsin are included in a Winter Weather Advisory that goes into effect this morning and lasts through this evening. It will go into effect for the Rockford area at 10am, but goes into effect for the Freeport area around 8am. A Winter Storm Warning will go into effect for Jo Daviess county with more sleet and snow accumulations expected, especially north of 20.

With the later arrival of the system, the window for freezing rain is getting smaller. This is due to warming temperatures ahead of the system, with most of the area noticing temperatures above the freezing mark. We will still have the threat for rain, sleet, thunder, and maybe even snow through the first half of the day. Rain will then begin to mix in with snow around 3pm this afternoon, turning to all snow around dinner time.

With less freezing rain, we do have a little more snow to deal with today.

Snow totals look to climb between one to two inches for the Rockford area, but three or more are possible across southern Wisconsin and far northwest Illinois (Jo Daviess Co.). Snow will wind down around midnight tonight and sunshine returns Thursday. Spring like weather sticks around into next week!
