Area Forecast Discussion
National Weather Service Cleveland OH
711 PM EDT Wed Apr 29 2026

.WHAT HAS CHANGED...
Added frost to the forecast for portions of the area on Thursday
night and Friday night. Chances of rain have trended up for
Friday, especially south of a line from Findlay to Youngstown.

&&

.KEY MESSAGES...
1) Below normal temperatures are expected through the weekend with
patchy frost on Thursday night and greater coverage of frost on
Friday night.

2) Opportunities for showers will linger through the end of the week
within this cooler pattern.

3) The weather pattern trends gradually warmer with the potential
for thunderstorms next week.

&&

.DISCUSSION...
KEY MESSAGE 1...

Low pressure is over western Pennsylvania and the associated cold
front is south of the area this afternoon. Temperatures range from
the upper 40s near the lakeshore to mid 50s inland. This will be the
beginning of a cooler pattern as an upper level trough sets up over
the Great Lakes Region through Saturday. Cold advection will
continue overnight with 850mb temperatures falling to around -2C for
Thursday and Friday before trending slightly cooler for Saturday.
Normal highs at the end of April are in the mid 60s but we will tend
to see high temperatures limited to the low to mid 50s for the next
3 days. Ample cloud cover tonight will keep temperatures near 40
degrees and do not expect to have any issues with frost. More breaks
are expected in the cloud cover from Thursday night through Saturday
night which will allow for colder overnight lows and potential for
frost. For Thursday night the frost looks to primarily effect
Northwest Pennsylvania while coverage of frost on Friday night looks
to encompass most inland areas. A ridge of high pressure will build
overhead Friday night with low temperatures generally in the low 30s
but could drop below freezing for inland portions of Northwest
Pennsylvania. Frost/Freeze headlines may be needed but will depend
on the degree of clearing over the next few nights.

KEY MESSAGE 2...

Rain associated with the cold front is exiting the area to the east
this afternoon while additional showers have developed upstream in
northern Indiana and western lower Michigan along a trailing surface
trough. These showers are expected to reach northwest Ohio this
evening then decrease in coverage as the trough swings southeast
across north central Ohio overnight. This axis of moisture will
remain a focus for showers to develop on Thursday afternoon with
steep low level lapse rates and a minimal amount of instability.

A shortwave trough will round the base of the upper level ridge
Thursday night into Friday. Weak low pressure will slide from
Illinois across Indiana and Ohio bringing a swath of rain Thursday
night into Friday. Chances of rain have trended up with this system,
with greatest potential focused along and south of Route 30.

KEY MESSAGE 3...

The persistent upper level trough finally shifts off the East
Coast on Sunday night, and temperatures trend back towards
normal on Monday. Showers and thunderstorms are possible both
along a warm front and then ahead of a cold front later Monday
as the next trough moves through the northwest flow aloft.
Temperatures trend warmer again on Wednesday with showers and
thunderstorms possible again.

&&

.AVIATION /18Z Wednesday THROUGH Monday/...
Widespread MVFR to IFR ceilings will continue overnight into
Thursday morning. Ceilings will gradually improve to MVFR/VFR
later Thursday afternoon/evening. YNG and ERI may have several
more hours of LIFR ceilings this evening before climbing to the
IFR category. Patchy drizzle and light mist will keep visibility
around 2sm to 5sm this evening and overnight. Winds will
generally be from the north to northwest 5 to 10 knots through
the TAF period.

Outlook...Non-VFR possible in showers and low ceilings late
Thursday night into Friday morning.

&&

.MARINE...
North to northwesterly flow expected through Saturday evening
across Lake Erie. Winds will be generally 5-15 knots during that
time with periods of lighter winds possible Friday morning.
Waves will continue to be 1-3 feet across that lake as well. By
Sunday, high pressure will build in south of the region and
winds will be 10-15 knots and shift to be westerly then
southwesterly by the evening into Monday.

.CLE WATCHES/WARNINGS/ADVISORIES...
OH...None.
