Area Forecast Discussion
National Weather Service Cleveland OH
729 PM EDT Sun Aug 3 2025

.SYNOPSIS...
An expansive area of high pressure across the Great Lakes and
Northeast will continue to influence the weather pattern through
mid-week.

&&

.NEAR TERM /THROUGH MONDAY NIGHT/...
Quiet weather is expected for the near term period as surface
high pressure persists underneath weak upper-level troughing.
Efficient radiative cooling will occur overnight, leading to
another comfortable morning on Monday with low temperatures in
the low to mid-50s. Seasonable highs in the low to mid-80s are
expected for Monday with comfortable dew points in the 50s.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
Mainly quiet weather appears to persist through the short term
period as the high pressure axis slowly shifts east towards New
England on Tuesday underneath weak upper-level troughing. A
weakening mid-level shortwave and associated surface trough will
gradually move north across the Ohio Valley on Tuesday, though
the latest guidance continues to favor a mainly dry forecast
with the western periphery of high pressure extending west
towards the OH/IN border. Nonetheless, an increase in cloudiness
on Tuesday is appearing more likely as the surface trough
approaches.

A similar scenario will play out on Wednesday as the surface
trough gradually slides east through the Ohio Valley. The latest
guidance continues to favor a mainly dry forecast with the
influence of high pressure across the Great Lakes and Northeast
extending south into northern Ohio.

Seasonable highs in the low to mid-80s are expected for Tuesday
and Wednesday.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
The quiet weather trend appears to continue for much of the
long term period as high pressure strengthens across the
Northeast and Eastern Great Lakes, amidst mainly weak, zonal
flow aloft. Shower and thunderstorm chances may begin to
increase by late Sunday with an approaching cold front and
upper-level trough across the Upper Midwest, though confidence
remains low at this time given timing differences of the front.

Seasonable temperatures in the mid-80s on Thursday and Friday
will increase to above average in the upper 80s to perhaps lower
90s by the weekend.

&&

.AVIATION /00Z Monday THROUGH Friday/...
High pressure will result in continued excellent aviation
conditions with clear skies tonight and increasing high cloud on
Monday. VFR expected to continue through the period with
scattered clouds around 5K after 16Z Mon. Light northeasterly
flow overnight will become more easterly on Monday and increase
to 8-12 knots during the afternoon. The exception is near Lake
Erie where CLE and ERI can expect land breezes from the
southeast between 03-16Z, then more north to northeasterly with
lake breezes during the afternoon.

Outlook...VFR continues through Tuesday. Non-VFR possible with
isolated thunderstorms Wednesday and Thursday.

&&

.MARINE...
Will continue with the pattern of southeasterly winds at night less
than 10kts becoming northeasterly 8-12kts due to lake breeze effects
during the afternoon hours. Waves could reach 1-2ft in the late
afternoon/early evening hours from the islands towards Cleveland in
the lake breeze winds, but otherwise, less than a foot expected.
This will persist through mid week.

&&

.CLE WATCHES/WARNINGS/ADVISORIES...
OH...None.
PA...Air Quality Alert from midnight tonight to midnight EDT Monday
     night for PAZ001>003.
MARINE...None.
