The radar
The Buffalo radar (KBUF), 142 km from the middle of the area, began a volume at 12:06 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Buffalo Intl Airport, NY (KBUF), launched 12:00Z, 0.0 hours before the alert went out and 143 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area Forecast Discussion
National Weather Service Cleveland OH
741 AM EDT Wed Sep 2 2026
.WHAT HAS CHANGED...
No major changes to the forecast with elevated heat risk and severe
weather the main impacts today and Thursday.
&&
.KEY MESSAGES...
1) Elevated heat risk conditions continue today for Ohio as heat
indices will be in the upper 90s to low 100s.
2) There will be severe weather potential across Northeastern Ohio
and Northwestern Pennsylvania this morning through overnight
tonight.
&&
.DISCUSSION...
KEY MESSAGE 1...
Well above normal temperatures will continue today along with
increased dew points keeping heat indices in the upper 90s to low
100s. The upper level ridge continues to be in place across the
southern CONUS allowing for persistent west to southwesterly flow
across the region to continue today into the overnight. This will
push highs today a touch warmer into the low 90s with dew points
climbing into the low to mid 70s again. Heat indices as a result
will rise up into the upper 90s to low 100s. Portions of Western
Ohio will be warmer than to the east as there should be limited
precipitation and cloud cover for much of the day. For Cleveland
eastward, precipitation is expected this morning and again in the
evening, but there should be a long enough break in between to allow
for temperatures to climb quickly. For the Northwestern Pennsylvania
areas, they will be far enough east to were temperatures shouldn't
climb up into the 90s, therefore heat indices will be below advisory
criteria. With that being said, it still will feel hot with heat
indices in the mid 90s, and precautions should be taken as needed.
Overnight lows Wednesday into Thursday will still be elevated as
well into the low to mid 70s offering little relief. Heat risk will
stay elevated at a level 3 out of 4 for the entire CWA due to this.
Thursday will start to bring some relief to the region as a cold
front approaches from the north and more widespread precipitation is
expected at some point during the day. Western and Central Ohio will
still have elevated heat indices and heat risk though, as
precipitation will not have reached before peak heating. There is
some uncertainty in this as morning convection may be moving across
the area that would limit the high temperatures for the day. If the
convection does not pan out, then thinking is that an area from
roughly Wayne/Holmes northwest to Lucas will need an extension in
the advisory. The remainder of the eastern portions of the CWA
should have enough precipitation and cloud cover to keep
temperatures and heat indices down in the upper 80s and low to mid
90s respectively.
Temperatures will begin to regulate Friday into the weekend to more
seasonal as Canadian high pressure builds south into the region.
Highs will be in the upper 70s to mid 80s with overnight lows in the
upper 50s to mid 60s through the weekend.
KEY MESSAGE 2...
More rounds of showers and thunderstorms are expected this morning
through the overnight hours. For this morning, there is a shortwave
trough located over Southern Ontario that will push southeastward
into New York through the mid-morning. This will help support
scattered showers and thunderstorms this morning across Northeastern
Ohio and Northwestern Pennsylvania. There will be some instability
in place along with around 40 knots of bulk shear that, if storms
organize, could support damaging wind gusts. Will monitor upstream
in Southern Ontario and Eastern Michigan for storm formation, but
currently storms across Western Michigan have started to weaken and
the environment may not be suitable for thunderstorm development.
There will be a break in the showers and precipitation once the
shortwave moves eastward and the next shortwave enters the region
later this afternoon/evening. This will allow for instability to
build back to around 2000 J/kg and lapse rates of 7-7.5 C/km across
Eastern Ohio and Northwestern Pennsylvania. Bulk shear will also in
the neighborhood of 30-40 knots in that same region. Thunderstorm
development is possible ahead of the shortwave with a more linear
mode expected with the shortwave later in the evening. The western
extent of this feature is still uncertain and could reach as far
west as Cleveland. The highest confidence in thunderstorms currently
for this evening is across far Northeastern Ohio and in Northwestern
Pennsylvania. This is shown in SPC's Day 1 Severe Weather Outlook as
there is a slight risk (level 3 of 5) from a line from Toledo
southeast to Canton and eastward with higher probabilities for
severe winds in Northeastern Ohio and Northwestern Pennsylvania.
Damaging winds will be the main threat with todays storms, though
large hail will also be a factor with the increased lapse rates and
instability. A quick spin up tornado is also possible though 0-1 km
bulk shear is minimal, so the threat is on the low end.
Thunderstorms should exit to the southeast around midnight.
Given the warm, moist environment over the region, PWAT values
will be around 1.5-2.00" across the region. The will bring the
threat for heavy rain with any thunderstorms and could cause
isolated flooding issues if there are persistent rainfall over
and area.
Additional thunderstorms are possible early Thursday morning as well
though there is still a lot of uncertainty in where and the severity
of these as it will be dependent on the storms from Wednesday
evening. A cold front will approach from the north throughout the
day on Thursday that will bring more widespread precipitation to the
region. The severe weather threat will be more focused on Central
Ohio with the better instability and lapse rates, though can't rule
out any storms to become severe across the region ahead of the
front. The front will be slow to move to the south and should exit
by late Thursday night.
Lingering showers and thunderstorms are possible Friday as another
shortwave moves through the region, though the severe threat should
be lower than previous days. High pressure builds into the region
from the north and should persist through the weekend with dry
weather expected.
&&
.AVIATION /12Z Wednesday THROUGH Sunday/...
Several rounds of convection are likely this morning across NE
OH and NW PA as clusters of thunderstorms over Lake Erie come
ashore. Strong to severe winds are possible with these storms,
as well as frequent lightning and hail. Storms are expected to
move out of the area by late morning, but a second round of
scattered convection will develop this afternoon and evening
across in roughly the same locations. At this time, uncertainty
exists as to the exact timing and location of these storms.
The rest of the region will stay VFR with scattered to broken
high and mid level clouds. South and southwest 5 to 10 knots
are expected, with a few gusts to 20 knots during the afternoon
hours.
Outlook...A cold front will slowly move across the area from
the northeast towards the southwest on Thursday. Scattered
showers and storms will bring non-VFR conditions Wednesday
night through Thursday night. High pressure and fair weather
will return Friday into the weekend.
&&
.MARINE...
Severe storms have made their way across eastern Lake Erie and
into the coastal waters this morning, with several rounds of
storms likely across the lake today and tonight as a cold front
eventually drops south. Wind gusts up to 40 knots are possible
in the strongest storms. Outside of thunderstorms, southwest
winds with 1-3 foot waves are expected.
A gradual wind shift to the north will occur by Thursday night
behind the cold front, with winds diminishing Friday. Northeast
flow over the weekend could result in some choppy conditions
with waves of 1-3 feet.
