national weather service milwaukee/sullivan wi
918 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
average height of the highest 10% of the waves which will
occasionally be encountered.

.synopsis...

winds will veer southeast tonight and accelerate thursday

pressure develops over the northern great plains. this low 
pressure system will slowly track east toward the central portion 
of the lake friday night. some 30 kt easterly winds may occur over
the northern tip of the lake thursday night and friday.

the low will pull a cold front across lake michigan friday

shift. showers and thunderstorms are expected late thursday night
through friday, both ahead of and along the front. severe weather
is not anticipated at this time.

northerly winds will continue through the weekend across lake 
michigan. 29.4 inch low pressure is forecast to track 
northeastward from the central great plains (sunday night) near or
over lake michigan (monday night), with gusty east to southeast 
winds ahead of its arrival and gusty west or northwest winds 
behind it (into tuesday). not seeing widespread gale potential 
with this system, though trends will be monitored.
