Scattered light showers on the backside of the departing low pressure will move into our area this afternoon, slowly ending from the west later this evening/overnight.

The associated occluded front (purple) swings north and then east across portions of Wisconsin and Michigan before bending south and becoming a cold front (blue) in Pennsylvania – from that point running through the Atlantic coast states and the Florida panhandle into the Gulf of Mexico. In addition to the extensive rainfall pattern surrounding the low center, a band of showers and t-storms will accompany and precede the frontal boundaries with potential severe storms across Florida (see Enhanced and Slight-risk severe areas on the severe weather outlook map below.
