The system that brought a few inches of snowfall Monday has led to a deep freeze across the upper Midwest Tuesday morning. Wind chill values were in the -10 to -25 degree range early on and we won't see them break out of the negatives at all Tuesday.
The National Weather Service has issued a Wind Chill Advisory from 9 pm Tuesday through 12 pm Wednesday. Wind chills exceeding -25 degrees will be possible by Wednesday morning as air temperatures fall into the negative teens.
Once wind chill temperatures fall below -18 degrees, frostbite is possible within 30 minutes on exposed skin, so layer up.
It's possible that temperatures won't climb out of the negatives at all through Wednesday afternoon, before we see them slowly climb above zero overnight into Thursday.
Another clipper low pressure system will bring relief from the bitter blast, but it will replace the cold with a few fresh inches of snow. This system will be similar to Monday with reduced visibility, snow covered roadways, and delayed travel times during Thursday commutes.
As of now, snowfall totals look to be in the 1 to 3 inch range with models suggesting higher totals to the north and east of Eau Claire. This system has not developed yet so watch for changes into Wednesday.
