855 pm cst tue feb 3 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...

high pressure around 30.4 inches over far western wisconsin will
slide southward into iowa overnight into wednesday. mainly light 
winds are expected. lake effect snow showers are possible over 
the southern half of the open waters overnight through wednesday 
afternoon. winds will trend west southwesterly wednesday night 
into thursday, as low pressure around 29.5 inches moves from the 
canadian great plains to western hudson bay. snow is possible 
during the day on thursday, ahead of the developing low.

low pressure will deepen further to near 29.3 inches over 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 friday, with trends being monitored 
for potential headlines in coming forecasts. areas of snow showers
will continue along and 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 high pressure
around 30.4 inches crosses lake michigan, prior to increasing 
once more saturday night, as the feature moves east.
