.SYNOPSIS...High pressure, 30.50 inches, builds into the western Great Lakes
today while flurries linger over the central waterways until this
evening. The ridge briefly centers over southern Lower Michigan
tonight, but then gets forced out on Tuesday by an Ontario low
pressure system and its cold front. The trough feature crosses the
northern Great Lakes Tuesday, clipping the northern waters of Lake
Huron which results in a few additional light snow showers. A warm
front lifts across the Great Lakes region Wednesday offering milder
and wetter conditions midweek.
