.SYNOPSIS...

Breezy south winds across Lake Michigan this afternoon will
diminish and become westerly overnight as weak high pressure of
29.9 inches moves east across the lower Great Lakes region. Light
westerly winds will be in place to start the day on Thursday, but
are expected to turn easterly and accelerate by Thursday afternoon
as low pressure deepens to 29.5 inches over Wisconsin Thursday
night into Friday. As the low pressure system moves across
Wisconsin on Friday, winds across the southern half of the lake
will generally be from a south to southwesterly direction whereas
winds across the northern half of the lake will be from an
east to northeasterly direction. Gusts across the lake will be
around 20 KT on Friday. Showers and thunderstorms are also
possible across the lake on Friday associated with the low.
As the low moves across central Lake Michigan Friday night, winds
will become more variable, but will become northwesterly for the
start of the weekend as the low lifts northeastward into eastern
Canada.
