Weather Underground midday recap for Thursday, May 02, 2013.
A late season winter storm brought record breaking snowfall to Minnesota, Wisconsin, Iowa, and Missouri on Thursday. The system developed as a strong trough of low pressure moved off the Rockies and through the Plains, which pushed a cold front through the center of the nation. Cold air poured in behind this cold front, with overnight low temperatures dropping into the teens and single digits across the Northern Plains. Daytime highs slowly recovered into the mid-40s for the Northern Plains and Upper Midwest. Heavy snowfall developed along the cold front from northern Wisconsin, thorugh southern Minnesota, and across Iowa. A wintry combination of freezing rain and snow developed across Kansas and northwestern Missouri. As the system slowly moved eastward throughout the day, precipitation spread into the Great Lakes and Mississippi River Valley. Record breaking May snowfall totals were reported with this system. In Dodge Center, Minnesota saw 15.4 inches of snow early on Thursday, while Rice Lake Wisconsin saw 17.0 inches of new snow.
Meanwhile, the southern side of this system pulled warm and moist air in from the Gulf of Mexico, which allowed for showers and thunderstorms to develop across the Southern Plains and Lower Mississippi River Valley. Just east of this activity, another system over the eastern Gulf of Mexico brought severe showers and thunderstorms to Florida. Rainfall totals surpassed 4 inches across southern Florida, with many reports of strong and damaging wind gusts from Palm Beach to Key West.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of 3 degrees at Monarch Pass, Colo. to a midday high of 90 degrees at Camarillo, Calif.
