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... a weak 29.8 inch high pressure ridge will drift 
across the western great lakes tonight. as the ridge builds to 
29.9 inches while shifting toward the lower great lakes on 
saturday, a 29.3 inch low over southern manitoba will push an 
associated 29.6 inch trough eastward to western lake superior late
in the afternoon. this trough will weaken to 29.9 inches while 
sailing across the rest of lake superior during saturday night. 
the parent low pressure that was over southern manitoba on 
saturday will weaken to 29.6 inches as it moves over far northern 
ontario during sunday. to its south, look for a 30.0 inch high 
pressure ridge to settle over the upper great lakes. as this ridge
builds to 30.1 inches while quickly shifting to the mid-atlantic 
coast on monday, a 29.8 inch trough will develop northeast to lake
superior and upper michigan. on tuesday, a 29.4 inch low pressure
will track northeast to the upper mississippi valley. this low 
deepens to 29.3 inches, centering over upper michigan early 
wednesday.

935 pm edt fri may 17 2024

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... a weak 29.8 inch high pressure ridge will drift 
across the western great lakes tonight. as the ridge builds to 
29.9 inches while shifting toward the lower great lakes on 
saturday, a 29.3 inch low over southern manitoba will push an 
associated 29.6 inch trough eastward to western lake superior late
in the afternoon. this trough will weaken to 29.9 inches while 
sailing across the rest of lake superior during saturday night. 
the parent low pressure that was over southern manitoba on 
saturday will weaken to 29.6 inches as it moves over far northern 
ontario during sunday. to its south, look for a 30.0 inch high 
pressure ridge to settle over the upper great lakes. as this ridge
builds to 30.1 inches while quickly shifting to the mid-atlantic 
coast on monday, a 29.8 inch trough will develop northeast to lake
superior and upper michigan. on tuesday, a 29.4 inch low pressure
