open lake forecast for lake erie
national weather service cleveland oh
258 pm est thu dec 4 2025

for waters beyond five nautical miles of shore on lake erie

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 ridge averaging 30.40 inches affects lake erie through friday
night as the embedded high pressure center moves from near the
upper mississippi valley to atlantic waters near nova scotia. on 
saturday, a cold front should sweep generally southeastward 
across lake erie. the front should waver in a north-south manner 
in vicinity of lake erie on sunday as a low wobbles east-northeastward
from near the east-central great plains to the northeast united 
states and deepens slightly to 29.90 inches. on monday, a ridge
averaging 30.50 inches should build from the upper mississippi
valley through about midday and then begin to exit eastward during
the rest of monday through tuesday. this should allow a warm 
front to sweep northeastward across lake erie later on monday.

open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
234 pm cst thu dec 4 2025

for waters beyond five nautical miles of shore on lake michigan.

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...

southwest winds will increase this evening to gale force over the
northern half of the lake as an area of low pressure around 29.6 
inches moves across southwestern ontario. a gale warning is in 
effect from late this evening through mid morning friday. freezing
spray is also expected during this time. 

a cold front extending south of the low will cross the lake friday
night. southwesterly winds remain breezy (25-30 kt gusts) ahead of
the cold front friday, gradually subsiding and veering northwest 
behind it. northwest winds gradually decline throughout saturday 
then become light and variable saturday evening as a weak surface 
ridge of high pressure builds into the region. stronger high 
pressure tracking southeastward through the dakotas and a weak low
pressure system tracking eastward past southern illinois will 
work together to drive north winds around 20-25 kt on sunday.
