open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
240 pm cst sat jan 24 2026

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 30.7 inches will remain over the western great
lakes through today, with a convergent zone bringing lake effect 
snow potential to the southern half of lake michigan from this 
afternoon into sunday. high pressure slides eastward tonight as
low pressure of 29.6 inches develops in the lower mississippi
valley. expect the convergent zone to strengthen tonight, with 
lake effect snow continuing. northeasterly winds are expected east
of the band, with northerly winds west of the band. the band will
transition westward toward wisconsin sunday morning, then back 
eastward sunday afternoon and evening. all winds shift to 
northwesterly sunday evening as low pressure moves into the mid- 
atlantic. high pressure centered over the southern plains then 
dominates the pattern through midweek, leading to generally 
westerly winds. a few clipper systems are possible early to 
midweek, bringing periods of 25 to 30 kt gusts. gusty winds 
combined with frigid temperatures will lead to moderate / heavy 
freezing spray sunday night through tuesday. a heavy freezing 
spray warning is in effect.

30.7 inch high pressure centered over the lower great lakes 
maintains 30.6 inch ridging over lake superior this evening. ridging 
over the lake weakens to 30.3 inches into sunday, then further to 
around 30.1 inches into monday, as a 29.6 inch low moves northeast 
along the atlantic coast. a 29.8 inch clipper low crosses the lake 
monday night into tuesday. another clipper low, much weaker at 30.1 
inches, grazes the northeast portion of the lake on wednesday. a 
strong high pressure descending from the canadian prairie around 
30.7 inches late next week brings ridging back to lake superior, 
likely persisting into next weekend.
