The NWS warned in a Wednesday update that the Great Lakes are "most at risk" for more severe storms with an enhanced risk for severe weather over western Michigan and a slight risk over the state and portions of the Midwest. 

The agency cautioned that damaging winds, large hail, tornadoes and flash flooding could threaten communities as scattered thunderstorms impact the Midwest to the East Coast, Gulf Coast and Florida over the next couple of days.
