Thunderstorms Monday from the Ozarks through the Midwest
An area of low pressure currently over southwest Minnesota will intensify as it moves northeastward into Lake Superior by this evening. To the south of the low, a strong trailing cold front will surge southeastward into portions of the Midwest and South. Increasing moisture and strong winds aloft will set the stage for the development of scattered thunderstorms along the front this afternoon. Initially, storms may form in a semi broken line but by early this evening, storms will congeal into an eastward moving squall line. The primary threat with some of the better organized thunderstorms within the line will be damaging winds in excess of 50 mph. A brief tornado cannot be ruled out. The severe potential is low overall, but a few severe storms are anticipated. The severe weather threat will end as the front passes.

A Look Ahead
The area of low pressure and cold front described above will continue to progress eastward on Tuesday, bringing the potential for rainfall from the Great Lakes southwestward into Texas. Rain will transition to snow across the Northeast Tuesday evening. On Wednesday, some light snow may develop across the Dakotas. This activity may expand across the Northern Plains on Thursday. Some moderate rainfall may develop along the East Coast on Friday in response to an area of low pressure off the East Coast.
