DISCUSSION

Surface cold front is settling southward across the southern lakes. Shower coverage in northern lower MI is gradually decreasing, though low clouds are expanding in northern lower MI. Cooler/ drier air is making inroads into the northern lakes, with dew points already in the 40s in much of upper MI.
Relatively tranquil over the next couple of days, as upstream cool/dry air overspreads the region. Some opportunity for early morning fog/low clouds in the rain-cooled and -moistened airmass in northern MI. Once any of that erodes, mostly sunny skies expected. Abundant sunshine today and Thursday will largely counter the cooler incoming airmass, leaving us with seasonable max temps. However, a cool night is forecast tonight, with most of the interior dipping well into the 40s.
Upper low over Hudson Bay will make slow eastward progress this week. However, as it departs, it gets replaced by energy diving southward out of central Canada. This carves out an upper low in the Great Lakes region by late in the weekend. Warm advection in advance of the digging system will start to increase cloud cover and eventually pops, beginning Thu night. Chance for showers arrives in western/northern areas Thu night. Showers/storms are then likely at times Friday into Saturday.
Cooler but still moist air will enter by the close of the weekend. Some showers chances will continue, especially downwind of the Great Lakes. (Yup, its about to be /that/ time of the year...for a day or two.) Moderating temps early next week, with for now only small precip chances, until system timing becomes more certain.
