Tonight will be mostly clear and bitterly cold. Temperatures will fall to the middle single digits above zero by late evening; overnight low temperatures will fall to between 5 and 10 degrees below zero with wind chills from -10 to -20 by morning.

Friday will be mostly sunny and very cold with high temperatures only reaching the middle teens. Friday night will be bitterly cold once again with low temperatures falling into the middle single digits below zero, but with light winds, wind chills should not be much of a factor.

Temperatures should moderate a little this weekend, but should still stay well below normal. Saturday will be partly sunny and not quite as cold with high temperatures near 20 degrees. Low pressure will develop in the southern Plains on Saturday and move toward the Midwest, bringing light snow or flurries to southern Wisconsin from late Saturday night through Sunday with minor accumulations possible. Highs will reach the middle 20s on Sunday.

Monday will be partly sunny and cold with high temperatures near 30 degrees. A strong area of low pressure will develop to our southwest, and move through or just north of southern Wisconsin on Tuesday. Skies will turn mostly cloudy on Monday night, and a mix of light snow, sleet, and freezing rain will develop, but will change to rain and isolated thunderstorms on Tuesday as temperatures climb above freezing early in the day, rising to near 40 degrees in the afternoon. A cold front will sweep through Wisconsin late in the day, causing temperatures fall again Tuesday evening, changing rain to a period of freezing rain and eventually back to snow before tapering to flurries overnight into early Wednesday morning. 

Much colder air will continue to sweep through Wisconsin on Wednesday. It will be variably cloudy and windy with a chance for flurries. High temperatures will be near 20 degrees early Wednesday morning, but temperatures will fall through the teens during the day. Skies will turn mostly clear and it will turn bitterly cold on Wednesday night, with low temperatures falling to the middle single digits below zero and wind chills from -10 to -20. Thursday will be mostly sunny, but very cold with high temperatures in the middle teens. Temperatures will begin to moderate on Friday, with partly sunny skies and breezy conditions. High temperatures will climb back to the upper 20s.
