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...

lake superior is currently between a 30.5 inch high offshore of new 
england and a 29.7 inch low stretched out from nebraska toward 
quebec. currently, this stretched-out low signs of splitting into a 
pair of 29.7 inch lows, one that remains in the central plains and 
another that moves eastward into quebec. as these lows get pushed 
south by 30.4 high pressure building in from manitoba and hudson 
bay, low pressure to 29.8 inches transits south across lake 
superior, and southerly winds shift to northeasterly. by monday 
night, the high will weaken to 30.2 inches over quebec as the plains 
low moves into the upper great lakes region at 29.7 inches. as the 
low escapes to new england tuesday into wednesday morning, a new 
30.2 inch high forms over the dakotas, moving over lake superior at 
30.3 inches early thursday morning. thursday, the high shifts toward 
new england as a 29.8 inch alberta clipper swings southeast through 
manitoba. the alberta clipper tracks over lake superior friday 
morning, followed closely by impressive 30.7 high pressure reaching 
from nunavut to texas.
