- Rain Mid-Week then Cooler

Tropical moisture will graze southeast Lower Michigan tonight with low chance POPs there, then fair and warm weather expected into Monday before a shortwave trough rides over the top of upper ridging across the SE CONUS with a low pressure center tracking across the central Great Lakes on Tuesday. This is followed by a full latitude upper trough developing across the eastern CONUS by next weekend and the potential for a stronger low on Wed-Thu although ensemble spread remains considerable on the details.

At this point it seems possible rain will be around for Wednesday and Thursday with sharply cooler weather for Friday and beyond.
