A chilly day but not as cold as previous arctic blasts that we’ve had this winter. Highs today were in the single digits and teens. Skies were mostly sunny today with some passing mid to high level clouds dropping south across parts of the area. We got rid of the wind today, and this combined with copious amounts of sunshine really made for a nice winter day around here despite the cooler than average temperatures.
Tonight: Some clouds at times as warm air advection spreads south into the upper Midwest. Lows will be in the single digits below to single digits above zero but a few locations could slip into the teens below.
Wednesday: Partly cloudy skies are expected during the day with more clouds tomorrow night thanks to a potent vort max which moves through the Northland late tomorrow night. There will also be a surface low and warm front moving through the area tomorrow night. Not a lot of moisture with these features so only expecting a few flurries or snow showers at best in parts of our area tomorrow night. Highs Wednesday will be in the 20s to lower 30s with lows Wednesday night in the teens and 20s.
Note: My 4 eyes continue to monitor a potential storm system (could be a whopper) for late this weekend. The track of this storm will likely shift around from model run to model run but this will be a storm to watch as it could bring a combination of heavy snow and strong winds to portions of the upper Midwest and western Great Lakes from late Sunday into Monday. The computer models will continue to fine tune the track, timing and area at greatest risk for significant snowfall in the days ahead.
