open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
258 pm cdt sat apr 27 2024

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...

low pressure around 29.5 inches over lake superior will continue 
to gradually weaken as it moves into ontario this evening. gusty 
south winds are expected across lake michigan this afternoon, 
with a few gusts approaching or reaching gale force, especially in
the northeast portion of the lake. areas of dense fog may
redevelop this evening over the northern portion of the lake as
the winds become lighter, while dense fog may form over the 
southern portion of the lake late tonight into sunday.  

winds will then gradually shift from southwest to northerly 
tonight as a cold front tracks south, but southerly winds will 
continue over far southern lake michigan as the front stalls. 
brisk northeast winds will then prevail over central lake michigan
on sunday with lighter winds in the north, and variable winds in 
the south where the stalled front remains. modest east to
southeast winds will then develop over all of the lake sunday
night as the stalled front moves north as a warm front. brisk east
winds, possibly reaching gale force, are expected over the
northern tip of the lake late sunday night into monday morning.
breezy south winds will develop over the remainder of the lake on
monday. 

rounds of showers and thunderstorms are expected tonight into
monday morning. a few of these storms could produce locally gusty
winds and hail.
