257 pm cst wed dec 17 2025

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...

low pressure around 29.1 inches will track eastward along the 
canadian border tonight into thursday, bringing southerly gales 
from late evening through thursday morning. a lull in the gales 
may occur thursday afternoon as low pressure crosses the upper 
peninsula of michigan. winds become west and accelerate back to 
gale force behind a strong cold front thursday evening, then 
eventually turn northwest thursday night. a gale warning is in 
effect for all open waters of lake michigan late this evening 
through early friday morning.

moderate freezing spray is expected to accompany the gales late 
thursday night into friday morning as a bitter cold airmass 
briefly enters our region. 

friday night, another low pressure system swings through southern
canada, bringing gusty south-southwest winds once again. gales are
possible, but confidence is lower with timing and intensity at
this time.
