- Next chance for rain Friday and Saturday

Quiet weather this week under high pressure with the next chance for rain coming at the end of the week into the weekend. A shortwave tough rounds the top of the western CONUS ridge and closes off across or just south of the Great Lakes.

A surface low meandering across the Ohio Valley brings a moist easterly flow into Lower Michigan where mid level f-gen forcing and instability should bring rain and embedded thunderstorms with some diurnal enhancement over the weekend. Although the current forecast does not have POPs early next week, some showers could linger into Monday and even Tuesday before he upper low gets kicked out.
