Thunderstorms Monday across the Midwest
As an area of low pressure continues to move slowly to the northeast, thunderstorms will continue along the warm front. This activity will be scattered as it moves northeastward throughout the day and into the evening. If these storms remain organized, ample moisture and strong wind shear will aid in the development of discrete cells. Strong winds, heavy rainfall, and small hail will be the primary hazards with these storms.

A second round of thunderstorms may move over this same region on Saturday. The risk for thunderstorms will move into the Great Lakes and Midwest on Sunday as the system over the Northern Plains continues to move eastward.
