****All counties in northern Illinois and southern Wisconsin are under a Winter Storm Watch effective Monday night through Tuesday night.****
An area of low pressure will begin to develop in the southwest Monday and move into the Ohio River Valley by Tuesday evening. As it does, it will draw in moisture from the Gulf of Mexico and combine with an upper level disturbance currently moving south out of Canada through the northern Plains. Because temperatures will be somewhere in the mid to upper 20s, forecast snow/water ratios will be a little higher than the typical 10:1 - closer to 15:1. This will allow the snow to fluff a little more. Current precipitation amounts coming out of some of the models are suggesting over a half an inch of precipitation. That would yield us over 6 inches of snow. Some of the National Weather Service offices are suggesting close to 10 inches by Wednesday morning. As the low pulls off to the east Tuesday night and Wednesday, winds will become very gusty in its wake so blowing and drifting will then become the concern.
Eric will have an update on the forecast during the newscasts this evening and Candice will have an update Monday morning. It looks like the heaviest of the snow will fall Monday night into Tuesday. Be sure to keep checking back for the latest.
