national weather service milwaukee/sullivan wi
232 am 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...

winds will continue to taper across lake michigan today as 30.7
inch high pressure moves in from the west. wave heights will 
likewise decrease with wind speeds, resulting in rapidly 
diminishing heavy freezing spray potential through sunrise. the 
heavy freezing spray warning will thus expire as scheduled at 3 am
cst this morning. low pressure of 30.5 inches remains forecast to
form over the southern waters today, bringing lake effect snow 
potential to the southern half of lake michigan from this 
afternoon into sunday. the low's development will bring 
increasing northeast winds tonight through sunday. winds are 
expected to remain below gale thresholds.

winds will trend northwesterly to westerly sunday night into monday 
as 29.6 inch low pressure moves into the northeastern united 
states and 30.7 inch high pressure builds into the central great 
plains. a brief period of southwest winds is forecast monday 
evening/night as 30.6 inch high pressure builds into the ohio 
river valley. winds will then shift back to west-northwesterly 
tuesday morning as 30.5 inch high pressure builds into the 
northern great plains. periods of 25- 30 knot gusts are 
anticipated from sunday night through tuesday morning, with a few 
gusts approaching gale force possible over southern lake michigan 
monday night. will continue to monitor trends for possible 
headlines in coming forecasts. the breezier conditions will be 
accompanied by areas of moderate to heavy freezing spray sunday 
night into tuesday. a heavy freezing spray watch has been issued 
between 6 pm cst sunday and 6 pm cst tuesday given this potential.
