301 am cst mon nov 2 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 30.5 inches will linger over the mid-atlantic 
states through dawn this morning before slowly shifting further 
eastward into the atlantic ocean. light south to southeasterly winds 
continue early this morning, increasing later this morning as low 
pressure around 29.4 inches lifts northeast across the plains and 
into mn. winds will continue to increase across lake michigan ahead 
of the incoming low pressure with gusts approaching or exceeding 
gale force over the central third of the lake for a few hours 
tuesday afternoon. given the brevity, trends, and uncertainty with 
this southerly gale setup, will continue to monitor for if headlines 
will be necessary later forecasts. rain will accompany this low 
pressure system tonight through midweek, with a few thunderstorms 
possibly mixing in at times. 

then the low pressure is expected to meander near the upper 
peninsula of mi and lake superior for midweek, leading to continued 
gustier south winds across lake michigan. the low pressure will then 
slowly exit eastward for the second half of the week, allowing winds 
to veer west and eventually north as high pressure around 30.2 
inches builds across ontario, which should allow winds to gradually 
lessen into the weekend.
