305 am cst fri nov 6 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...

breezy northerly winds continue as a tight pressure gradient 
remains over lake michigan between low pressure of 29.5 inches 
over the upper great lakes and high pressure of 30.3 inches over 
the northern great plains. after an evening lull, expect an uptick
in the winds over the north half early this morning and the south
half around daybreak. northerly gales should linger through this
afternoon as the pressure gradient remains over the lake. a gale 
warning is in effect for all of lake michigan. we may see gale 
conditions end sooner for northern portions of lake michigan as 
the core of the higher gale force winds propagates south down
today.

in addition to the winds, cold air moving into the region paired 
with warmer lake temps will result in the potential for a 
waterspout or two for northern sections of the lake early this
morning, and then the middle to southern parts of lake michigan 
friday. 

high pressure then builds over the upper great lakes today 
through the weekend, bringing lighter northwesterly winds.low
pressure around 29.4 inches crossing ontario will drag a weak cold
front across lake michigan on sunday. highest gusts up to 30 kt 
are expected over the north half. the next low pressure system 
will cross lake superior monday night.
