Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this flash flood warning; the first came 126 minutes after it went out.
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
Pittsburgh, PA (KPIT), launched 00:00Z, 0.9 hours before the alert went out and 145 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
750 PM EDT Wed Jun 10 2026
.WHAT HAS CHANGED...
No significant changes to the forecast with this update. Hot and
humid conditions will continue through tomorrow.
&&
.KEY MESSAGES...
1) Scattered chances for showers and thunderstorms continue
ahead of a cold front that will push across the region Friday.
2) Hot and humid conditions ahead of the cold front with little
overnight relief anticipated. Cooler weather behind a cold
front Friday into the weekend.
&&
.DISCUSSION...
KEY MESSAGE 1...
An upper level trough is currently over the North Central U.S.
and the western Great Lakes region. There is a small upper level
ridge over the Ohio Valley today. Our area is ahead of a cold
front that is located over the Upper Midwest and across the
Cornbelt region. Looking ahead for the rest of the afternoon and
evening, mostly dry weather conditions are expected. There could
be a few widely scattered pop-up showers or thunderstorms
through the evening hours. Our attention will be looking
westward later this evening and overnight for a decaying MCS
that may potentially move into our area. High-res forecast
guidance is somewhat uncertain on timing and coverage of this
possible complex of convection. SPC does have the entire area in
a marginal risk for severe storms and far NWOH in a slight risk.
The main severe weather hazard would be damaging wind gusts.
Again forecast confidence on timing and scope of possible
convection is somewhat uncertain.
The weather pattern for tomorrow will be similar as today. The
area will be will be on the warm side of an advancing cold front
through the Great Lakes and Midwest. Some widely scattered
convection may be possible during the daytime heating. POPs and
rain chances look higher for Thursday night into early Friday
morning as convection from the west moves across the area with
the associated cold front. Again, SPC has the area in a marginal
risk for severe storms with the main threat being damaging wind
gusts.
High pressure will build into the area later Friday and Saturday
with drier weather. Another cold front will move across the area
early Sunday with a chance for showers. An upper level trough
will develop over the Great Lakes region by next week with
scattered chances for showers.
KEY MESSAGE 2...
The heat and humidity will stick around through Thursday
evening. The current heat advisory for north central and
northwest Ohio will remain in effect through this evening. High
temperatures will reach the upper 80s and lower 90s this
afternoon. The heat index will be up to 100 degrees, especially
in the heat advisory area. Overnight low temperatures tonight
will not bring much relief in the lower to middle 70s.
Tomorrow's high temperatures will climb back into the upper 80s
and lower 90s with the heat index approaching 100 degrees again.
Additional heat advisories may be needed for north central and
northwest Ohio again Thursday. A cold front will knock the
temperatures down a little for Friday into the weekend. An upper
level trough will develop over the Great Lakes and Ohio Valley
by early next week with cooler temperatures in the 70s for
highs.
&&
.AVIATION /00Z Thursday THROUGH Monday/...
Thunderstorm activity ongoing right now across north-central and
northeast Ohio. In general, expect this activity to grow upscale
and dive southeast. This is most likely to impact KCLE/KCAK, and
then possibly KYNG over the next several hours. There is lower
confidence that storms reach KERI or KMFD.
Another line of storms over Indiana is moving eastward towards
the area, though this line has lost of lot of intensity, with
very little lightning at this point. At this point, it looks to
mainly impact KTOL/KFDY with rain, gusty winds, and a very low
probability of lightning. Additional thunderstorm activity is
possible late tonight, but there is very low confidence and
wasn't included in the TAFs just yet.
Winds are generally out of the southwest this evening, 8 to 12
knots. Winds will begin to favor a more westerly direction late
Thursday morning and afternoon, 8 to 12 knots.
Outlook...Non-VFR possible in a line of showers and
thunderstorms Thursday night, particularly west of the I-71
corridor. Non-VFR may return in scattered showers and
thunderstorms Sunday afternoon.
&&
.MARINE...
The next marine concern will be late Thursday night into Friday
as a cold front briefly ushers in west winds of around 20
knots. At the minimum, a moderate rip risk is likely early
Friday, especially across the central and eastern basin with
waves of 2 to 4 feet. A lower potential for rough marine
conditions is also possible late Saturday night into Sunday as
another cold front ushers in west to northwest winds of around
15 knots.
There will also be a few chances for strong thunderstorms
impacting the lake with gusty winds over the next several days.
The first chance for strong storms will be late this evening
and overnight, with a higher likelihood Thursday night into
Friday morning as a line of showers and storms moves east into
the area.
