Quiet weather through thursday under high pressure with the next chance for rain coming on friday into the weekend. A shortwave trough rounds the top of the western conus ridge and closes off across or just south of the great lakes.

An associated 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 on saturday. Afternoon showers could linger into sunday and even monday before the upper low gets kicked out.
