winds, and hail are possible with these storms. storms will move 
north to south across the lake late tonight. monday, expecting a 
cold front to progress north to south across the lake in the

deepens to 29.5 inches over the eastern great lakes tuesday. winds

.synopsis...

no major changes to the going forecast this evening.

patchy dense fog is expected in portions of the central to
northern lake michigan through tonight and potentially monday as 
warm moist air moves northward. 

severe storms are possible during the early morning hours within 
that warm air mass across lake michigan. waterspouts, very strong 
winds, and hail are possible with these storms. storms will move 
north to south across the lake late tonight. monday, expecting a 
cold front to progress north to south across the lake in the 
afternoon hours. this will bring the next chances for severe 
weather, with strong winds and hail the main threats. northerly 
winds are expected behind the front, with gusts around 30 kt 
expected. gusts to gale force cannot be ruled out as low pressure 
deepens to 29.5 inches over the eastern great lakes tuesday. winds
will remain northerly through wednesday as high pressure around 
30.0 inches builds into the northern great lakes, then will become
lighter and more variable into thursday and friday as high 
pressure builds overhead.
