The final day of astronomical winter is here and our weather will turn out quite nice across Western Wisconsin as high pressure dominates to the southwest. This will give way to plenty of sunshine as we close out the weekend, though breezy winds are expected out of the west and southwest at 10-15 mph. Temperatures later this afternoon are forecast to run much closer to average in the upper 30s and lower 40s. Clouds will then begin to increase tonight, out ahead of a weak low pressure system that will become situated along the Minnesota/Iowa state line tomorrow with its associated cold front stalling out over South-Central Wisconsin. There won’t be much forcing and moisture available to generate precipitation, so the start of spring looks to stay dry with even some intervals of sunshine as temperatures climb to right around normal in the low 40s.

On Tuesday, the boundary will still be stalled to our south while another storm system comes together in Eastern Colorado as it begins to track northeast during the day. Mostly cloudy skies will stick around with scattered rain and snow showers possible as the low draws closer. More in the way of widespread rain and snow looks to overspread Western Wisconsin Tuesday night as our weather-maker builds into the Upper Midwest. Temperatures are forecast to hover near and above freezing at night, so minimal snow accumulations are currently anticipated. As the low works through and to the northeast Wednesday, more showers are possible with breezy winds and highs back in the 40s. Looking ahead to later this week, forecast guidance continues to show a large upper trough digging out across the Western United States with a couple storm systems developing to our south. There is still uncertainty on what happens to the trough as it slides further east. A few more rain and snow showers can’t be ruled out Wednesday night into Thursday, but any appreciable precipitation currently looks to stay south of our area with dry weather now expected Friday. Seasonable temperatures will carry through the entire week as highs consistently stay in the low to mid-40s.
