National Weather Service Milwaukee/Sullivan WI
848 AM CST Sun Jan 11 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

Northwest gales will ease later this morning as low pressure of 29.5 inches tracks east across Quebec and strong high pressure of 30.7 inches over the central Great Plains weakens to 30.5 inches. Winds gradually ease and turn westerly late this afternoon, with a brief resurgence of west to southwest winds late tonight (to around 30 kt at times) due to a passing surface pressure trough. Light west to southwest winds continue into Monday.

Breezy south to southwest winds expected Tuesday ahead of another low pressure system around 29.3 inches. This low pressure system will track east across Lake Superior Tuesday afternoon, shifting winds to northwesterly once again Tuesday night. There is potential for north to northwesterly gales into Wednesday.
