high pressure of 30.7 inches will remain over the western great

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 potential for 
moderate to heavy freezing spray sunday night through tuesday. a 
heavy freezing spray watch is in effect.

open lake forecast for lake superior
national weather service marquette mi
1000 am est sat jan 24 2026

for waters beyond 5 nautical miles of shore on lake superior.

waves are the significant wave height - the average of the
highest 1/3 of the wave spectrum. occasional wave height is the
average of the highest 1/10 of the wave spectrum.

.synopsis...

30.8 inch high pressure centered over wisconsin this morning is 
maintaining 30.7 inch ridging over lake superior today. ridging over 
the lake weakens to 30.3 inches on sunday 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.
