Weather Underground midday recap for Monday, March 11, 2013.
Another winter storm continued across the Midwest on Monday and became centered over the Upper Great Lakes by the afternoon. Cooler temperatures to the north and west of this system supported a mix of light to moderate scattered rain and snow showers in the Upper Great Lakes. Generally light snow totals of 1 to 3 inches were possible across areas from Iowa through Wisconsin into Michigan by Monday night. At the same time, an associated cold front moving pushing across the Eastern Valleys toward the Appalachians met with ample moisture from the Gulf of Mexico and allowed for more showers, periods of heavy rain, and thunderstorms to develop ahead of the front from the southern Great Lakes to the Central Gulf Coast. Areas of southern Alabama and the Florida Panhandle saw the greatest potential for thunderstorm development through the afternoon.
Meanwhile, out West, a few scattered snow showers developed along and near a frontal boundary dropping across the Northern and Central Rockies.
Temperatures in the Lower 48 states Monday have ranged from a morning low of -7 degrees at Baudette, Minn. to a midday high of 80 degrees at Plant City, Fla.
