Area Forecast Discussion
National Weather Service Cleveland OH
308 PM EST Mon Nov 10 2025

.SYNOPSIS...
A trough will persist across the Eastern Great Lakes through
Tuesday, followed by another low pressure system and cold front
on Wednesday. High pressure will then build across the region
Thursday and gradually weaken by Saturday.

&&

.NEAR TERM /THROUGH TUESDAY NIGHT/...
Main concern for the near term period will be the the continued
potential for heavy lake effect snow across Northeast Ohio and
Northwest Pennsylvania, particularly later this evening into
Tuesday morning when the highest snowfall rates are expected.
Current headlines remain unchanged with this update with an
additional 3 to 5 inches of snow expected in the Advisory areas
and generally 5 to 8 inches with isolated amounts up to 10
inches for the Warning areas.

Periodic and mostly loosely-organized and transient lake effect
snow bands continue across portions of Northeast Ohio and
Northwest Pennsylvania this afternoon, with impacts largely
confined to the more persistent and heavier snow bands. Looking
towards this evening and overnight, main focus will be on the
loosely- organized northwest to southeast lake event band
impacting Ashtabula County this afternoon, aided by an upstream
Lake Huron moisture connection. We anticipate this band to
become more intense and organized as surface convergence
increases this evening, potentially resulting in snowfall rates
up to 2 inches per hour at times across portions of inland Erie
and Crawford Counties (PA). There may be another lake effect
band, albeit somewhat less intense, that impacts portions of
eastern Cuyahoga/Geauga/northern Summit and Portage Counties
with snowfall rates up to 1 inch later this evening.

Will also be watching further to the west Tuesday morning as an
upper-level ridge begins to build east across the region,
shifting boundary layer flow towards the west. A surface trough
will also swing through the Eastern Great Lakes which will increase
surface convergence and potentially squeeze out a brief period
of moderate to heavy lake effect snow for the Tuesday morning
commute across the eastern Cleveland metro with rates up to 1
inch per hour. Otherwise, the building ridge will gradually
shift any residual lake effect snow northeast along the
lakeshore, and eventually offshore by Tuesday evening as the
next low pressure system approaches.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
A low pressure system will move east through the Great Lakes on
Wednesday, though any lake effect precipitation is initially expected
to remain offshore Wednesday morning. This lake effect
precipitation will eventually move onshore across Northeast Ohio
and Northwest Pennsylvania Wednesday afternoon and evening as a
cold front pushes east through the area, resulting in a mixed-
precipitation type of rain and snow.

An upper-level ridge and surface high pressure will build
across the region on Thursday, setting the stage for a period of
quieter weather over the next several days in addition to
increasing temperatures.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
Above-average temperatures in the mid to upper 50s and perhaps
even lower 60s are favored for much of the long term period as
an upper- level ridge persists across the Central CONUS/Great
Lakes into Sunday. By late Sunday, an upper- level trough will
sweep east through the Great Lakes, accompanied by a low
pressure system and cold front at the surface bringing
widespread rain to the region. Slightly seasonably-cool
temperatures in the upper 40s to near 50 will return behind the
front on Monday.

&&

.AVIATION /18Z Monday THROUGH Saturday/...
Cold cyclonic flow will keep areas of stratus, with ceilings
ranging from high MVFR to low VFR, rotating through the area
through the TAF period. The main focus for more significant
impacts will be lake effect snow showers. We are expecting a
relative increase in organization and intensity this evening,
centered between 22-4z, a brief overnight lull, and then another
relative increase in organization and intensity between about
10z-16z Tuesday. The most intense snow will be with a Lake
Huron connected band, currently impacting far Northeast OH but
likely shifting into Northwest PA tonight, and then east out of
Northwest PA by late Tuesday morning. There will likely be a
couple of somewhat weaker bands at times farther west, including
in the vicinity of CLE, with these bands extending towards YNG
and perhaps CAK. Any organized lake effect band can bring IFR
or lower vsby and quick snow accumulations, though confidence in
impacts at given terminal are low given the narrow, multi-banded
nature of the lake effect setup. Attempted to use TEMPOs to
indicate windows when impacts are most likely at each given
terminal. There are somewhat higher odds of impacts at CLE and
ERI, with lower odds at YNG and CAK.

The main flavor with any bands tonight into Tuesday will be a
gradual east to northeast shift in band location as winds shift
from their current NNW direction to more NW this evening, WNW
overnight tonight, and west on Tuesday. Winds of 8 to 15kt with
occasional gusts to 25kt, especially near Lake Erie, are
expected through the TAF period.

Outlook...Periods of non-VFR conditions will continue in
northeast Ohio and northwest Pennsylvania with lake effect
showers through midweek.

&&

.MARINE...
Northwest winds 15-25 knots will increase a bit into the 20-30
knot range tonight and Tuesday, with winds gradually backing to
a more due westerly direction by Tuesday afternoon. Winds
shift more southwesterly Tuesday evening into Wednesday,
increasing a bit more to 25-35 knots (with potential for 40 knot
gusts) Tuesday night. Winds weaken slightly on Wednesday, but
hang in the 20-30 knot range. In general, winds will be
strongest across the central and eastern basin and relatively
weaker across the western basin. Winds will start gradually
subsiding while remaining west-southwest Wednesday night and
Thursday, finally falling below 15 knots across the entire lake
late Thursday night as high pressure builds in. Tranquil marine
conditions should linger into the start of the weekend.

Small Craft Advisories remain in effect for all nearshore zones
until 8 PM Tuesday. A Gale Watch kicks in east of Avon Point
from 7 PM Tuesday to 4 AM Wednesday, where the greatest
potential for winds to marginally reach sustained gales exists.
West of the Gale Watch, Small Craft Advisories will need to be
extended, though will do that once we get the gale headlines
more hammered down. A Low Water Advisory will likely be needed
from Tuesday afternoon into Wednesday due to the prolonged
period of strong southwest winds.
