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...

high pressure around 30.1 inches will remain parked over the 
southern appalachian mountains into the weekend. meanwhile, a low 
pressure system around 29.5 inches will track across ontario and
reach toward james bay by thursday night. breezy south to 
southwest winds will persist through thursday. southwest winds 
will weaken becoming light thursday night through friday. heading 
into the weekend, high pressure in the appalachian range will 
gradually shift east. as the high pressure pulls away, there is a 
potential for low pressure around 29.7 inches to move into the 
great lakes region for the weekend. 

chances for storms (30-60%) will persist from this afternoon 
through friday evening across the southern two thirds of the lake.
additional chances for rain/storms remains across the entire lake
saturday and sunday. strong to severe storms may occur at times, 
though confidence remains low in timing of stronger storms.

patchy marine fog will be possible at times, primarily over the 
northern half of the lake as the warm and moist airmass moves
overhead.
