908 am cdt mon jun 22 2026

for waters beyond five nautical miles of shore on lake michigan.

is the average of the highest 1/3 of the wave, along with the

.synopsis...

low pressure around 29.8 inches will continue eastward across the
ohio river valley today, with high pressure around 30.2 inches
building southeastward into the great lakes region. the pressure
gradient between these two systems will drive a modest north
breeze over lake michigan today with speeds up to 25 kt at times,
mainly over the southern two thirds of the lake. lighter 
northerly winds are expected late this evening into tuesday as 
the high pressure continues to build into the region. winds will
become light and variable tuesday night as it tracks overhead. by
wednesday, the high pressure will exit to the southeast and low 
pressure around 29.9 inches will track from the northern plains 
into northern wisconsin. as the low approaches, breezy south to 
southeast winds will develop across the lake.
