for waters beyond five nautical miles of shore on lake michigan.

waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.

.synopsis...

elevated waves and cold temperatures will support moderate to 
heavy freezing spray through tuesday afternoon. a heavy freezing 
spray warning is in effect until 6 pm cst tuesday.

a 29.6 inch trough of low pressure will cross lake superior
tonight. gusty southwest winds this evening will veer to the west
overnight, and to the northwest tuesday morning. a 3 to 6 hour 
period of gale force gusts up to 35 kt is expected between 9 pm 
and 3 am cst, mainly over the south half of the lake. we held off
issuing a gale warning due to the marginal and brief nature of 
this event. 

diminishing winds will trend west-northwesterly tuesday afternoon
and night as 30.4 inch high pressure builds into the northern 
great plains. winds will gradually taper wednesday through 
thursday as said area of high pressure moves into the upper 
mississippi river valley. strong high pressure around 30.9 inches 
will set up over the northern plains on friday and expand across 
the upper great lakes at 30.7 inches over the weekend.
