258 pm cst tue nov 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...

two low pressures both around 29.5 inches sit over mn and kansas 
today. they will both slowly congeal over the upper mississippi 
river valley into one system this evening into tonight. this will
drive gusty southerly winds across the lake through wednesday. 
expecting 30kt gusts across much of the lake during his period 
with a window for gales across the central third of the open 
waters through 6 pm cst. thus, a gale warning remains in effect 
for this aforementioned area. 

otherwise, periods of rain and a few rumbles of thunder will 
accompany the merging low pressures today through midweek before 
deepening to around 29.4 inches. the low pressure will slowly 
move across northern wi into the lake superior region by thursday.
will continue to see the low pressure progress east into quebec 
through the end of the week bringing more westerly then northerly 
winds to lake michigan, but are expected to remain below gales at
this time. then high pressure around 30.2 inches will build into 
the upper great lakes region behind the departing low for the 
weekend bringing lighter winds.
