Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched 2 storm reports to this severe thunderstorm warning; the first came 13 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, 0.1 hours before the alert went out and 111 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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Cleveland, OH wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 1, 7:42 PM EDT, 22 minutes earlier.

Area forecast discussion, Jul 1, 7:42 PM EDT, 22 minutes before

Area Forecast Discussion
National Weather Service Cleveland OH
742 PM EDT Fri Jul 1 2022

.SYNOPSIS...
A cold front will cross the region overnight and settle south of the
area on Saturday. High pressure will build over the region for the
remainder of the weekend and into New York on the 4th of July.

&&

.NEAR TERM /THROUGH SATURDAY NIGHT/...
Update...
Tweaked forecast a bit to better time out remaining showers and
storms this evening. As we head further into the evening hours
tonight lightning will cease across the region. Remaining
showers look to exit the area late this evening and into the
overnight hours from west to east.

Previous discussion...
The cold frontal passage tonight is the main weather event
during this period. Despite plenty of solar heating today,
MLCAPE remains rather modest for July with values generally
below 1000 J/KG. Effective wind shear is low but is expected to
increase to 30-40 knots this evening. Convection is developing
along the front in Michigan and along I-70 where deeper moisture
resides. We still expect scattered showers and storms to spread
into the region over the next several hours and some
development is occurring along the lake breeze near CLE. With
limited CAPE and a steep lower level lapse rates, DCAPE values
are somewhat supportive for microburst development in some of
the stronger cells. The convective activity will diminish after
sunset and largely end by 12Z Saturday.

High pressure will gradually build into the region for the rest of
the weekend and provide generally fair and cooler weather. There
could be an isolated shower Saturday afternoon west of I-71 but we
will not mention it in the forecast.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
Cold front will remain over the Ohio Valley Sunday, with high
pressure taking control of the lower Great Lakes. All precipitation
will lie along the front, so anticipate dry weather through Monday
morning.

By Monday, a warm front will begin to lift north towards the local
area. Moisture may begin to increase across the area as early as
Monday afternoon and can't rule out widely scattered showers and
perhaps a few isolated thunderstorms Monday afternoon. Long range
guidance is still hinting at a complex of thunderstorms moving
southeast across the Upper Midwest and possibly into NW OH late
Monday night into early Tuesday which will need to be watched, but
at the moment it looks like the complex will be weakening as it
moves into a drier environment. Will continue to monitor the
thunderstorm potential for late Independence Day and update and
message any threats if needed.

Temperatures will be near normal Sunday and will begin to increase
once again Monday. Most locations will reach the upper 80s to lower
90s, although NW PA may be a few degrees cooler. Sunday night will
feature lows in the upper 50s to lower 60s, with slightly warmer
temps possible close to the lake.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
An unsettled weather pattern will continue through the majority of
next week as a frontal boundary drapes itself across the region.
Several vorticity maxima will ripple along the front, leading to
several opportunities for scattered showers and thunderstorms, best
chance during peak heating during the afternoon and evening. Still
too early to get too specific with PoPs, as any precipitation
chances will be highly dependent on the location of the front along
with any boundaries that are left behind from previous convection.

Temperatures will be near to a couple of degrees above normal
through next Friday. As stated in the previous discussion,
temperatures will be influenced by any cloudiness.

&&

.AVIATION /00Z Saturday THROUGH Wednesday/...
Showers and thunderstorms are expected to exit the region from
west to east tonight and into the overnight hours. Upstream
reports indicate that lightning is beginning to cease across the
region, already coming to an end across western terminals (KTOL
and KFDY). Any lingering thunderstorms look to remain over KERI
and KCLE for a brief period of time to begin this TAF period,
looking to end around 02Z. As showers and storms exit the
region, VFR conditions return and will persist through the
remainder of the TAF period.

Southwesterly winds at 10-15 knots become westerly at 5-10 knots
overnight and into Saturday morning. Winds become northwesterly at
10 knots or less through the rest of the TAF period.

Outlook...Non-VFR possible at times in showers and thunderstorms
Monday night into Wednesday mainly in the afternoon and early
evening.

&&

.MARINE...
Southwest winds 10 to 15 knots will continue through this evening as
a cold front approaches from the west. Scattered showers and
thunderstorms may move across the lake with the cold front this
evening and winds and waves will be locally higher near convection.
The passage of the cold front will result in northwesterly winds
around 6 to 12 knots and waves of 2 to 3 feet. Winds become
southwesterly in the wake of the front Saturday, before veering to
the northeast by Sunday morning. Waves may build to 2 to 3 feet from
the Islands to Willowick due to enhanced onshore flow Sunday
morning, but not anticipating any headlines at this time. Wind
direction will become variable Monday through Wednesday, but wind
speeds should remain below 15 knots.
