The first area is up in the Upper Midwest, where we have a mesoscale convective system (a line of thunderstorms) producing damaging winds and large hail. There are embedded supercells within the line of storms, which accounts for the unusual amount of large hail reports coming from the area. It will continue to move east through the afternoon as it impacts areas of southern Minnesota and northern Iowa.

The second area of severe storms is expected to fire up across the southeast later this afternoon. The storms will form in groups and lines, bringing the threat of 70+ MPH winds and hail up to golf ball size in the strongest storms. The SPC has already issued a severe thunderstorm watch for this afternoon and evening across parts of the eastern Carolinas, with a slight risk for severe weather extending west from the Atlantic coast through central Alabama.
|Counties under a severe t'storm watch until 10PM EDT Saturday May 5 2012|
