140 pm cst mon nov 2 2026

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

.synopsis...

low pressure near 29.4 inches will progress into the upper

29.5 inch low pressure will stagnate over northern wisconsin on

gale thresholds. winds will taper by the weekend as 30.0 inch 
high pressure builds into the western great lakes.
