.SYNOPSIS...The central Great Lakes are positioned between
approaching low pressure from Wisconsin and stalled high pressure
over Quebec. A warm front associated with the low has been slow
to lift into the southern waterways. The warm front precedes the
track of the low late tonight as it heads toward The Straits.
Some strong thunderstorms are still possible overnight. Drier
conditions expected Friday, after the system`s cold front clears
through. However, unsettled weather returns Friday night and
Saturday with a similarly tracking warm front and surface low.
