Very cold weather gives way to a weekend warm-up; winter storm potential Tuesday/Wednesday of next week

NextWednesday

MADISON, Wis. — After several inches of accumulating snow on Monday, clear skies and a Canadian air mass will bring another round of cold weather to southern Wisconsin from Tuesday night through Thursday night. Temperatures will rebound quickly back to around 40 degrees for the weekend. Another winter storm system will be possible from later Tuesday through Wednesday of next week.

Temperatures will be well below normal for Wednesday and Thursday. Low temperatures will fall to the middle single digits above zero for Wednesday morning with wind chills as cold as ten below zero early in the day. Thursday morning will be even colder as low temperatures fall to the middle single digits below zero and wind chills approaching fifteen below zero at times. High temperatures will only reach the upper teens for both Wednesday and Thursday.

Milder weather will return by the weekend. Temperatures will begin to climb on Thursday night, reaching high temperatures around 30 degrees on Friday and around 40 degrees for the weekend.

The longer-range computer models show a winter storm system developing around the middle of next week. Temperatures may be warm enough initially to have precipitation begin as rain or a mix of rain and snow on Tuesday afternoon, but as colder air arrives, the precipitation should change to snow for Tuesday night and Wednesday.

However, while the models are in agreement with a storm system in this part of the country at that time, a small shift in the path of the storm could bring in slightly higher temperatures that would lessen the chances for accumulating snow.

A small shift in the storm to the south could bring the potential for a major winter storm with over a foot of snow somewhere near southern Wisconsin. The models are also showing some differences in the timing of the storm, with the potential to delay it by almost a day.

Colder weather will arrive after the storm for the end of next week through the following weekend. The Climate Prediction Center’s 8-14 Day Temperature Outlook shows below-normal temperatures for almost the entire country.
