The radar
The Buffalo radar (KBUF), 134 km from the middle of the area, began a volume at 20:26 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 severe thunderstorm 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, 8.4 hours before the alert went out and 135 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, Jun 17, 4:02 PM EDT, 22 minutes before
Area Forecast Discussion
National Weather Service Cleveland OH
402 PM EDT Mon Jun 17 2024
.SYNOPSIS...
An upper level ridge will persist over the region through this
week, resulting in widespread near-record temperatures across
the area. The next system won't arrive until the end of the
weekend.
&&
.NEAR TERM /THROUGH TUESDAY NIGHT/...
Scattered showers and thunderstorms are developing across the
forecast area this afternoon, as convective temperatures are
being reached in the mid 90s and surface dew points start
broaching the 70 degree mark across northern Ohio. However, with
no real forcing other than the diurnal forcing, coverage is
just scattered across the region. However, the environment for
these storms is generally supportive for strong to severe
convection with SBCAPE values reaching over 3500 J/kg, DCAPE
values exceeding 1000 J/kg, and low level lapse rates in excess
of 8 C/km, which will support robust, quickly growing updrafts
that will support severe sized hail and tall enough cores that
could descend as downbursts with winds over 60 MPH. Several
Severe Thunderstorm Warnings and Special Weather Statements are
ongoing and the environment appears favorable for strong to
severe storms through early evening. Convection will move east
of the area later this evening and subside with a more stable
environment with the loss of diurnal heating. Residual cloud
cover across the region from this afternoon's storms could
remain for some portion of tonight and help keep temperatures
slightly elevated with lows likely not escaping the 70s for most
of the forecast area.
Tuesday appears to be a rinse and repeat of today. An abnormally
warm summer air mass will allow for temperatures to exceed 90
degrees and dew point values will once again approach the 70
degree mark. This will allow for heat index values to exceed 100
degrees and the Heat Advisory will remain valid. Temperatures
should hit convective temperatures again with the diurnal cycle
and scattered showers and storms will be present again. Storms
could once again have a bite with an generally unstable
environment to support some strong to severe wind and hail. Any
convection will also taper off temperatures and heat index
values from hitting the Heat Advisory values. Residual clouds
and abnormally warm air mass will have another dry, but warm
Tuesday night with lows likely staying above 70 degrees.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
Strong upper high will maintain itself over the eastern CONUS
through the short term period with southerly flow, deep moisture
advection, and steamy temperatures continuing through mid to
late week. As stated in the previous discussion from last night,
the main challenge is how much convection occurs during this
time and how much that will impact the temperatures and dew
points. Regardless, temperatures will likely climb well into the
90s each day with spots in NW OH most likely reaching the upper
90s to around 100 degrees. There won't be a ton of respite
overnight; overnight lows will be in the 70s with the warmest
temps expected in urban areas and dew points in the upper 60s
to lower 70s. In locations that don't receive rainfall, heat
indices will likely climb into the upper 90s to lower 100s and
the Heat Advisory remains in place through the entirety of the
long term period.
As far as precip chances go, maintained slight chance PoPs
during peak diurnal heating/instability; shower and thunderstorm
placement will rely on the exact placement of the upper ridging
over the area in addition to any boundaries from daily lake
breezes since there won't be much lift otherwise. Similar to
today, there will be quite a bit of buoyancy and moisture in the
atmosphere so any storms that develop could produce gusty
downbursts and locally torrential rainfall.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
By Friday, the upper ridge will largely weaken and flatten out,
but deep southerly flow and warm air advection will persist
through Saturday so still expect highs in the 90s with heat
indices in the upper 90s to lower 100s on Friday. Dew points may
begin to decline slightly Saturday, so heat indices will likely
remain in the 90s. As with previous days, there may be diurnal
convection so there are slight chance PoPs during each
afternoon.
Still some uncertainty in the time of arrival of the next
system, but a cold front will likely slowly advance east towards
the area late in the week and into the weekend with a cold
front likely sweeping across the area at some point Sunday or
Sunday night. This will deliver the next widespread chance of
showers and thunderstorms and finally some relief from the
heat to the CWA. By Sunday, highs will be back into the upper
80s to lower 90s with much cooler highs in the 80s (even 70s in
NW PA!) likely by Monday.
&&
.AVIATION /18Z Monday THROUGH Saturday/...
VFR conditions are at the terminals this afternoon with the
exception being any terminal being impacts by a scattered
thunderstorm. Storms will continue across northern Ohio over the
next several hours. Some storms have had a bite with them with
gusts over 30 kt but confidence in that impact at a terminal is
very low. Convection will subside with the diurnal cycle tonight
and trend to VFR. Will need to monitor for fog overnight, where
convection occurred the atmosphere has some chance to decouple.
Afternoon cumulus and new shower/storm chances will be possible
toward the end of the TAF period. Winds will favor southerly
through the period.
Outlook...Primarily VFR expected through Friday. Isolated
thunderstorms are possible Tuesday afternoon, but confidence is
low.
&&
.MARINE...
Outside of the potential for isolated showers and thunderstorms
(best chance this afternoon/evening and Tuesday), quiet marine
conditions with offshore winds under 10 knots and brief periods
of light onshore flow with daily lake breezes are expected
through Saturday. Do not expect any marine headlines this week.
&&
.CLIMATE...
A prolonged stretch of hot weather is expected this week.
Temperatures are forecast to approach or exceed record highs on
several days. The records for Monday, June 17 to Friday, June
