.MARINE...
A surface low tracks northeast across southern Lake Michigan this
afternoon and up across the northern half of Lake Huron tonight,
bringing an uptick in winds and chances for thunderstorms through
tonight. As this surface low lifts northeast across Michigan the
easterly winds will increase, especially across northern portions of
Lake Huron and into the Straits into the evening hours, with gusts
up to around 25 kt. Winds become southwesterly overnight as the
surface low exits Lake Huron and moves north into Ontario. The
latest guidance is now showing southwest winds increasing a bit more
than previously forecast, thus have increased southwest winds to
around 25 kt for tonight across the Saginaw Bay area and out across
central portions of the Lake Huron open waters. The main window for
these enhanced wind gusts looks to be fairly brief, between
approximately 11pm tonight and 6am Friday morning. Further south,
winds will not be as strong.
As the surface low continues to exit the region into Friday, winds
become westerly and weaken. A cold front then drops south across the
region on Friday, bringing north to northeast winds of 15-25kt. We
then get locked into this pattern with persistent north to northeast
flow through the weekend.
