Rain in the early afternoon before a quick transition to snow tonight
Rain has started to move in to western Wisconsin as our low slowly tracks to the northeast. We are expecting to see rain transition to snow fairly quickly to the far norther portion of the state where winter storm warnings are in effect, with a slower transition to snow for most of the viewing area. That being said, accumulations are expected to remain fairly light for most of us. Temperatures started out in the mid 40s this morning, but will drop fairly quickly once we get on the backside of the low. A tightening pressure gradient will bring some blustery northerly winds, funneling in colder temperatures. In the wake of this rain/snow that is expected to taper off around midnight, some untreated roads may have a few slick spots in the morning as we dip to the upper teens by daybreak.
As our surface storm system pulls away on St. Patrick’s Day Friday, a large upper low will settle into the region with more cloud cover and a few snow showers or flurries possible. It will be a rather windy finish to the work week with gusts up to 30 mph and highs below average in the mid-20s. Isolated flurries carry into the start of this weekend as the upper low exits to the east, while our next high pressure system drops into the Great Plains. Breezy winds will continue from the northwest, leading to more cold air as temperatures hang out in the 20s once again. By Sunday, abundant sunshine returns with temperatures pushing closer to average in the lower 30s as our high dominates to the southwest. More sun is expected as we welcome astronomical Spring on Monday with winds turning out of the southwest as we start to get behind high pressure. This will usher in a warming trend with seasonable temperatures to kick off the new week, followed by a climb through the 40s into the middle of next week with some spots further south nearing 50 degrees for the first time this year by Wednesday!
