A slow-moving storm system will continue to lift out of the Mid-Mississippi River Valley and generate mainly spotty, light showers this morning into this afternoon. As the heart of the low pressure moves closer to Northwest Ohio and Southeastern Michigan, rain coverage and intensity will increase this evening and overnight and could generate some thunderstorms into Tuesday morning.
Once the low moves off to the east with it's trailing cool-front, we will see big improvements with gradual clearing occuring as soon as Tuesday afternoon. Until then, keep your umbrella handy as it will be needed from time to time.
Midweek, high pressure moves into the region and will deliver plenty of sunshine for Wednesday and Thursday. High temps will swing from the upper 70s into the mid 80s by Thursday afternoon.
Look out for some strong storms moving in Thursday night into Friday as a dynamic cold-front rumbles through. That front will deliver a cooler airmass in it's wake with highs on Saturday struggling to reach the lower 70s, very unusual for the middle of August.
