national weather service cleveland oh
253 pm est thu jan 8 2026

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 high pressure ridge averaging 30.00 inches exits slowly eastward
from the lake erie region today. during tonight through friday, a
potent low should wobble northeastward from the upper mississippi
valley to southern quebec and weaken to 29.80 inches. accordingly,
a warm front should sweep northeastward across lake erie tonight 
before a cold front sweeps southeastward across the lake on 
friday. behind the cold front, a ridge averaging 30.10 inches 
should build briefly from the northern great lakes and vicinity 
friday night. on saturday, another low should wobble northeastward
from near the lower ohio valley to near lake huron, deepen to 
29.30 inches, and allow a warm front to sweep northeastward across
lake erie before a cold front sweeps generally eastward across 
the lake. behind the cold front, a trough averaging 29.90 inches 
should linger over lake erie on sunday. during sunday night 
through tuesday, a ridge averaging 30.30 inches should affect lake
erie as the ridge axis moves from the western great lakes toward 
the north atlantic.

open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
231 pm cst thu jan 8 2026

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...

southerly winds across lake michigan will gradually turn as low 
pressure around 29.2 inches lifts from the mo/ia border into the 
northern half of lake michigan overnight. will see gusty south to 
southeasterly winds over the southern half of lake michigan this 
evening as the low approaches then veering to southwest overnight.
lighter more easterly winds are expected for the north half of 
the lake, but gradually weaken as the low pushes northeastward 
into friday morning. behind the low, expect more north to 
northwesterly winds pick up into friday morning. given the tight 
pressure gradient on the backside of this departing system, will 
see gusts of 30 knots and a few brief gale force gusts through 
late friday morning, especially along the eastern lakeshore. 

winds will gradually weaken friday afternoon as high pressure 
around 30.2 inches works its way across the lake michigan through 
friday night. then looking at two areas of low pressure one coming
up from the southern plains and another digging down across the 
upper midwest merging over the great lakes for saturday. expect 
west- northwesterly winds over lake michigan to increase on the 
backside of this deepening low pressure as it lift into eastern 
ontario/quebec. will be a potential for gales across the open 
water, but still some uncertainty on the overall strength of the 
low pressure. then another high pressure will build across the 
region for sunday before another system traverses the region early
next week.
