The radar

The Cleveland radar (KCLE), 81 km from the middle of the area, began a volume at 22:06 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 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

Pittsburgh, PA (KPIT), launched 12:00Z, 10.0 hours before the alert went out and 105 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 30, 4:17 PM EDT, 1 hour 45 minutes earlier.

Area forecast discussion, Jul 30, 4:17 PM EDT, 1 hour 45 minutes before

Area Forecast Discussion
National Weather Service Cleveland OH
417 PM EDT Tue Jul 30 2019

.SYNOPSIS...
A cold front will move across the area through the overnight. High
pressure will then build over the region by Wednesday evening then
persist into the weekend.

&&

.NEAR TERM /THROUGH WEDNESDAY NIGHT/...
A cold front will continue to move across Ontario and Michigan
through the evening but it will slow as it moves across the
southern/southeastern CWA. Starting to see some dry air move
into the region with it beginning to impact the current
convection. POP's may end up being a bit too high this evening
but dont want to get too aggressive yet. So expect to see the
current showers/thunderstorms move southeast with the initial
wind shift. Will then see what can hold together under the upper
level trough as it interacts with the cold front.
Isolated/scattered coverage is expected through the overnight.
May even see a few showers linger through the day on Wednesday
across the southeastern CWA. High pressure should take control
of the region by Wednesday evening with dry conditions
anticipated.

It will be cooler tonight with lows in the lower to mid 60s.
Highs on Wednesday will range from the mid 70s to around 80.
Even cooler Wednesday night with the dry air across the entire
region. Lows should dip the the 50s away from the lake.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
We begin our short term period with an amplified positive PNA
pattern. The upper level ridge over the southwest CONUS isn't
expected to go anywhere soon. High pressure over the Great Lakes
will continue to expand and move eastward on Thursday and
Friday becoming less defined by Friday night as the pressure
gradient significantly weakens. Much drier air is expected to
be in place and with no upper level forcing moving through our
area, precipitation is not expected. Temperatures should remain
near normal with high temperatures generally in the low 80s.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
Not much changes on Saturday as the large scale pattern doesn't
change much. Dry weather should continue with temperatures
relatively similar to Friday with it being a couple degrees
warmer in areas such as Toledo and Findlay. The GFS has a weak
shortwave moving southeast through the upper level
northwesterly flow on Sunday. This may produce some scattered
showers and thunderstorms on Sunday and thus have a slight
chance for most of the day on Sunday. Drier air returns for
Monday.

&&

.AVIATION /18Z Tuesday THROUGH Sunday/...
Initial wind shift is located from near KLNN to KMNN at 17Z
should continue to drift southeastward through the afternoon.
The strongest thunderstorms will be southeast of this boundary
in the better moisture. MVFR/IFR conditions will occur near
this convection. We will also need to monitor the true frontal
boundary moving southward across Michigan. This boundary doesnt
have as much moisture to work with but the instability under the
upper level trough will be enough to generate additional showers
and thunderstorms into this evening. These will be more scattered
in nature and tougher to pinpoint a time moving across any of
the terminals.

Winds vary across the region with west to northwest winds in
the wake of the initial wind shift mentioned above. Ahead of
this boundary southwest winds are common. Winds at all locations
will shift to the northwest and north as the cold front sweeps
across the region this evening into the overnight.

Some fog will be possible across the south where the low level
moisture will take the longest to be nudged southward. So expect
to see some MVFR/IFR fog develop after midnight.

OUTLOOK...Non-VFR possible Thursday morning with fog and
stratus.

&&

.MARINE...
Southwest winds will continue to decline this evening and veer
to the north after a cold front moves across the lake northwest
to southeast tonight. Those winds will continue to veer to
northeast and strengthen to 10 to 15 knots by 12Z Wednesday.
This will increase wave heights to 2 to 3 feet in the nearshore
zones between Cleveland and Sandusky Bay, creating hazardous
swimming conditions for swimmers Wednesday morning into the
early afternoon. High pressure will build in from the west to
centered over lower Michigan by 00Z Friday. Northeast to east
winds will continue through Friday night.
