national weather service buffalo ny
402 am est tue jan 13 2026

for waters beyond five nautical miles of shore on lake ontario

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...the axis of surface-based ridging attendant to a 30.5 
inch high over the tennessee valley will slide out across new 
england tonight, while a surface trough averaging 29.8 inches passes 
just to the north of the lake. another 29.3 inch low will then move 
from western ontario tuesday to southern quebec wednesday. this 
system will push its trailing cold front across the lake wednesday 
night, when a secondary 29.4 inch coastal low will develop along the 
mid-atlantic coastline. the secondary low will then track northeast 
to the gulf of maine thursday and to newfoundland friday, while 30.0 
inch high pressure slowly builds east across the great lakes. a 29.8 
inch low and attendant cold fronts will then slide across the great 
lakes saturday.

gusty west to southwest winds are expected across the lake today,

that low will deepen to 29.1 inches and will push east into
western quebec.

winds will rapidly increase to gale force behind the front, with
gales continuing into wednesday evening. gale warnings are in
effect for all of lake michigan. moderate to occasionally heavy
freezing spray is expected during this time as well. 

by late wednesday night high pressure of 30.3 inches will build
south across the upper mississippi valley, and will eventually
move across the lake on thursday, bringing lighter winds. winds
will briefly turn westerly to southwesterly thursday evening and
night, before another strong cold front sweeps across the region
