Short Term
Today
Tonight...and Thursday
An upper trough and weak surface front will drop south across Wisconsin this afternoon and evening. As they do, low level winds may become favorable enough for some light snow or flurries in the far north and across the Door Peninsula and perhaps Fox Valley.
Any snow accumulations would be a tenth of an inch or so. Highs today should be 5 to 10 degrees higher than yesterday, even with increasing clouds in the afternoon.
Snow showers or flurries should end overnight. Cloudy skies will keep temperatures from falling below zero in most places, with wind chills above advisory criteria.
Thursday will be even warmer than today, with some sunshine as well. Highs will be in the 20s with wind chills in the teens.
Long Term...Thursday Night Through Tuesday
The return of above normal temperatures as well as a few chances for light snow this weekend into early next week are the main highlights of the extended forecast.
Precip Chances...Long range ensembles show a few shortwaves moving through upper-level northwest flow this weekend into early next week. The first shortwave is progged to arrive Saturday, however, forecast soundings struggle to become deeply saturated which may inhibit any snow from reaching the ground. A second short-wave with a more moist air mass then looks to arrive late Sunday into Monday.
With warmer surface temperatures there is a chance for precip to fall as rain across the Fox Valley, while forecast thermal profiles suggest mainly snow across northern WI. NBM probs for 1" of snow across northern WI have increased to around 20% for this time period.
Temperatures...Warmer temperatures are on the way for this weekend as return flow develops over the region. 805mb temps are forecast to warm above 0C by Sunday which should allow surface temperatures to warm above freezing. NBM probs show a 20-40% for highs above 40 degrees in the Fox Valley and central WI Sunday with higher probs of 50-70% on Monday for all areas except the Northwoods.
