open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
310 am cdt sun apr 28 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 29.7 inches drifts northeastward through quebec 
early this morning. its cold front has already crossed two thirds of 
the lake, and will stall near the southern end of the lake today as 
the warm front of an approaching low pressure system collides with 
it. thus, north to northeast winds are expected across the majority 
of lake michigan today, with the fastest winds (up to 30 kts) in 
central lake michigan. expecting light and variable winds over the 
southern third of the lake (near the stalled front) and south winds 
at the far southern tip of the lake. 

modest east to southeast winds will then develop over all of the 
lake tonight 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 tonight into monday morning. breezy 
south winds will develop over the remainder of the lake on monday. 

areas of fog may form over the lake today, especially the southern
half. several rounds of showers and thunderstorms are expected 
between now and monday.
