open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
239 pm cdt tue jun 22 2021

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 of 30.1 inches will slide eastward through the
overnight hours and settle into middle appalachia by wednesday
morning. as this happens, westerly winds will become southerly
tonight. they'll remain modestly gusty, however as there will be a
low-level wind speed max above a shallow inversion. going into the
daytime hours tomorrow, low pressure of 29.3 inches will approach
the hudson bay region in canada. this will steepen the pressure 
gradient between the low pressure north and the high pressure to
the southeast. as a result winds will strengthen through the day
on wednesday and into the overnight hours on thursday. winds to
gale force look possible for the northern end of the lake for a
brief period early thursday morning. 

showers and a rumble of thunder or two will be possible over
northern end of the lake late this afternoon, and then over the
southern half of the lake tonight into wednesday morning. better
chances for widespread, stronger storms look possible on thursday.
