this morning an extensive area of high pressure was centered at 30.7 
inches over northern mn and far southwest ontario. this high will 
shift east today, encompassing all of the great lakes at 30.5 
inches. the high will shift east on monday as a 29.9 inch low moves 
from the canadian prairies to james bay, deepening to 29.7 inches. 
the low will drag a weak trough of 30.2 inches across lake superior 
monday night before weak ridging builds over the lake on tuesday as 
another, more compact high of 30.4 inches moves to james bay. 
another large area of high pressure will move into central and 
eastern canada by thursday morning. the strong high will help keep a 
29.7 inch low moving up from the southern plains to our south as it 
weakens to 29.9 inches by the time it reaches the lower great lakes 
wednesday night, dissipating thereafter.

national weather service marquette mi
400 am est sun mar 1 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...

this morning an extensive area of high pressure was centered at 30.7 
inches over northern mn and far southwest ontario. this high will 
shift east today, encompassing all of the great lakes at 30.5 
inches. the high will shift east on monday as a 29.9 inch low moves 
from the canadian prairies to james bay, deepening to 29.7 inches. 
the low will drag a weak trough of 30.2 inches across lake superior 
monday night before weak ridging builds over the lake on tuesday as 
another, more compact high of 30.4 inches moves to james bay. 
another large area of high pressure will move into central and 
eastern canada by thursday morning. the strong high will help keep a 
29.7 inch low moving up from the southern plains to our south as it 
weakens to 29.9 inches by the time it reaches the lower great lakes 
wednesday night, dissipating thereafter.
