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...

high pressure around 30.1 inches will remain parked over the 
southern appalachian mountains into the weekend. meanwhile, a low 
pressure system around 29.5 inches will track across ontario and
reach james bay by tonight. modest south to southwest winds will 
persist today becoming a bit lighter tonight and friday. heading 
into the weekend, high pressure in the appalachian range will 
gradually shift east. as the high pressure pulls away, there is a 
potential for low pressure around 29.7 inches to move into the 
great lakes region for the weekend. 

chances for storms (30-60%) will persist from this afternoon 
through friday evening across the southern two thirds of the lake.
additional chances for rain/storms remains across the entire lake
saturday and sunday. strong to severe storms may occur at times, 
though confidence remains low in timing of stronger storms.

patchy marine fog will be possible at times, primarily over the 
northern half of the lake as the warm and moist airmass moves
overhead.

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 broad 29.6 inch low over ontario and quebec will consolidate over 
northern quebec by this evening, keeping 29.9 inch troughing over 
the lake today. tonight, 30.1 inch high pressure develops over the 
southern appalachian range with 30.0 inch high pressure over mostly 
northern manitoba while broad troughing is in the lee of the 
rockies. friday, the manitoba high builds to 30.1 and expands over 
western hudson bay and far northwestern ontario. the high builds to 
30.2 inches over hudson bay saturday and into sunday as a weak 29.9 
inch low passes through the southern great lakes basin. monday, the 
high quickly becomes dislodged to the southeast by a 29.7 inch low 
over northern manitoba, sending the high over lake superior, 
northern ontario, and quebec. by tuesday, the high shifts to new 
england while the low moves into hudson bay.
