MIDDAY UPDATE:  Look for the snow to continue this afternoon, mainly in the form of snow showers.  The wind will stay strong, causing more blowing and drifting.  Visibility will be reduced to less than a mile.  Please use extreme caution if you have to travel.  So far from this storm, some spots have seen close to a foot of snow.

A few more inches can't be ruled out this afternoon. The Winter Storm Warning wraps up around dinner time.  Then we sit and wait for dangerously cold weather by Wednesday.

7 AM UPDATE: Drier air starting to move in around the low.  This could bring down the totals around southeastern Wisconsin, however, expect still at least 6" for the region.  The scattered snow shower threat continues for the rest of the day. 

A major winter storm will continue to hammer southeastern Wisconsin today, beginning to diminish slowly during the day. The heaviest of the snowfall will take place during the morning hours while the bulk of the moisture and energy clips the Great Lakes. Snowfall rates at times could be between 1”-2”. Gusty winds will reduce visibilities and create blowing and drifting. Many schools are canceled today. Snowfall totals could get over a foot in some parts. The majority of the area will see between 7”-14” of fresh snowfall when all said and done. A Winter Storm Warning will run until 6 pm today.

Once the snow moves out, the coldest air in nearly 23 years could hit Wisconsin. These temperatures will be brutal. In fact, the temperatures could stay below zero from Tuesday through Friday. Wind chills could fall as far as -50!
