national weather service milwaukee/sullivan wi
221 pm cdt wed apr 22 2026

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

.synopsis...

high pressure will shift from the northern great lakes to the

occur over the northern tip of the lake thursday night and friday. 

the low will pull a cold front across lake michigan friday

is not anticipated at this time.

northerly winds will continue through the weekend across lake
