national weather service milwaukee/sullivan wi
203 pm cst tue feb 3 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...

30.4 inch high pressure is centered over the upper mississippi 
river valley this afternoon, with 30.1 inch low pressure along 
the ontario-quebec border. placement of the two features is 
resulting in generally light northerly winds across the open 
waters. winds will weaken further tonight, becoming light and 
variable wednesday morning as the aforementioned area of high 
pressure moves across lake michigan. lake effect snow is possible 
over the southern half of the open waters late tonight through 
wednesday afternoon. winds will trend west-southwesterly 
wednesday night into thursday as 29.5 inch low pressure moves from
the canadian great plains to the western hudson bay. areas of 
snow are possible during the day on thursday ahead of the 
developing low.

low pressure will deepen further to near 29.3 inches over the 
central hudson bay thursday night, ultimately progressing into 
northern quebec during the day on friday. the low will pull a cold
front across the open waters in the process, resulting in a gusty
northwest wind shift early friday morning. a period of 
northwesterly gales remains possible during the afternoon and 
evening hours, with trends being monitored for potential headlines
in coming forecasts. areas of snow showers will continue along & 
ahead of the passing front thursday night into early friday 
morning. elevated wave heights will combine with arctic air 
settling in behind the cold front to support areas of moderate 
freezing spray friday afternoon into saturday morning. heavy 
freezing spray is possible, with the need for possible headlines 
being evaluated in coming forecasts. winds will briefly taper 
saturday afternoon as 30.4 inch high pressure crosses lake 
michigan, prior to increasing once more saturday night as the 
feature moves east of the waters.
