National Weather Service Marquette MI
1010 PM EDT Sat Jun 6 2026

For waters beyond 5 nautical miles of shore on Lake Superior.

Waves are the significant wave height - the average of the
highest 1/3 of the wave spectrum. Occasional wave height is the
average of the highest 1/10 of the wave spectrum.

.SYNOPSIS...

Ridging builds to 30.1 inches over Lake Superior this evening
through Sunday morning. Meanwhile, a 29.3 inch low over the Northern
Rockies stretches into the Northern Plains and Canadian Prairies
through Sunday night. By Monday afternoon, expect Lake Superior to
be between a 29.8 inch trough over Minnesota and 30.2 inch high
pressure over New England. The troughing weakens to around 29.9
inches before moving over Lake Superior on Tuesday. Pressure
continues to fall over Lake Superior through Wednesday as a Colorado
low lifts through the Northern Plains towards Lake Winnipeg,
strengthening to 29.6 inches by Wednesday night as the low deepens
to 29.2 inches over far northern Ontario. Another Colorado low lifts
into the western Great Lakes at around 29.5 inches by late Thursday.
