national weather service cleveland oh
352 pm edt thu oct 9 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 high pressure ridge averaging 30.50 inches exits slowly eastward
before a weak warm front sweeps northward across lake erie friday
morning. behind the front, a ridge averaging 30.40 inches should 
build from the southern appalachians and vicinity through friday 
night. on saturday, a weak low of 29.90 inches should drift
southeastward across the northern great lakes and vicinity, and 
allow the trailing cold front to begin to sweep eastward across 
western lake erie. during sunday, the low should drift farther 
southeastward to lake erie, devolve into a trough averaging 30.00
inches over lake erie and the upper ohio valley, and the cold
front should dissipate over and near central lake erie. a ridge 
averaging 30.20 inches should then build generally from the west
