What the National Weather Service calls “life-threatening wind chills” are expected to make a return appearance early next week.
The NWS La Crosse office issued a statement Friday afternoon that wind chills of 35 to 50 below zero are expected from Sunday night to Monday morning and again from Monday night to Tuesday morning.
The Weather Service is forecasting lows of 15 to 25 below zero and northwest winds of 15 to 25 mph, with frostbite possible in as little as 10 minutes.
A winter weather advisory is in effect for Lafayette and Iowa counties Friday until midnight, for 1 to 2 inches of snow and blowing snow driven by winds of up to 40 mph.
A winter storm watch is in effect for Grant County Sunday from 6 a.m. to midnight. The NWS predicts 3 to 4 inches of new snow Saturday night with winds to 30 mph by Sunday afternoon.
Predicted lows as of Friday afternoon are 13 below zero Sunday night, 20 below zero Monday night, and 13 below zero Tuesday night.
One school district has already canceled classes for Monday. However, the Platteville School District's professional day was part of the 2013–14 school district schedule at the start of the school year.
Schools were closed statewide Jan. 6–7 as a result of similar weather. Temperatures dropped as low as 21 below zero in Platteville Jan. 6.
