.SYNOPSIS...

Light and variable winds continue over Lake Michigan this evening.
More organized south to southeast winds will develop over the south
half overnight into Friday morning, with east northeasterly winds
over the north half as low pressure around 29.7 inches moves from MN
across central WI. This low pressure area will gradually track
eastward across the middle of Lake Michigan early Friday afternoon.
Modest southwest winds will prevail over central and southern Lake
MI at this time with northeasterly winds to the north. The winds
will then trend to north northwest Friday night into Saturday
morning as the low moves away across Lake Huron and southern
Ontario. The winds will then back to southwest during the afternoon
and evening, and southerly for Sunday as high pressure around 30.0
inches moves across Lake MI and tracks to the eastern Great Lakes.
