A cold front across the Deep South will continue its slow push east. An upper wave moving across the central Gulf Coast will allow an area of showers and thunderstorms to persist, especially closer to the coastline. A low pressure system is moving through the upper Midwest. Enough Gulf moisture has worked its way northward to produce a cluster of light to moderate rain showers over the north-central U.S.

The latest guidance affords only isolated areas of 4+ inches, primarily in northeast Wisconsin and northern lower Michigan.
