A Pacific storm is bringing areas of low elevation rain, moderate to heavy mountain snow, and high winds to the Northwest. Strong Santa Ana winds and very dry conditions are producing elevated to critical fire weather conditions in southern California. Isolated strong to severe thunderstorms are possible through early Wednesday morning across parts of northeast Texas into western Tennessee. Read More >
The snow was not the only problem with this storm as strong northwest winds buffeted the region producing blowing and drifting snow that closed most roads for a time across southeast Minnesota and northeast Iowa. Near white-out conditions also occurred for short periods in the open rural areas.
Snow continued to fall into Friday, March 2nd as the storm moved into eastern Wisconsin and eventually across Lake Michigan. Drifting snow continued to be a problem but the blowing snow and near white-out conditions subsided as the winds slowly decreased. The storm finally released its grip on the region Friday night.
This snowfall combined with the snow that fell from February 23-26 created a blanket of snow ranging in depth from around a foot up to two and a half feet. These two storms also put La Crosse into the record books with the most snow ever recorded over a 7 day period. The top three snowiest 7 day periods for La Crosse are:

The second major winter storm in less than a week took aim at the upper Midwest and delivered two rounds of winter precipitation to the area as the calendar turned to March. The storm took shape over the southern Plains states Wednesday February 28th and then started to move northeast toward the area. As it did, the first round of precipitation moved into the region that afternoon. Light to at times moderate snow fell through Wednesday night with totals ranging from just a trace to around 3 inches. As the storm moved into Missouri Thursday March 1st, dry air began to wrap into the system and the precipitation become more scattered across the immediate region while a heavy snow band set up from eastern Nebraska and western Iowa into southwest and south central Minnesota. Along with the dry air, warm air aloft also spread over the area which created a mixed bag of winter precipitation. Light rain was common across parts of northeast Iowa into southwest Wisconsin where temperatures warmed above freezing. Farther north, temperatures remained below freezing setting the stage for snow, sleet and freezing rain to fall. Ice accumulations of 1/8 to 1/4 of an inch were reported from Wabasha and Winona counties in Minnesota and across parts of Trempealeau, Clark, Monroe and Adams counties in western and central Wisconsin. Temperatures once again fell below freezing across the entire Thursday night as the low slowly moved northeast into southern Wisconsin. This allowed all the precipitation to change back over to snow and some of this was quite heavy from southeast Minnesota into north central Wisconsin. Storm totals in excess of 10 inches were common in these areas.
