Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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

Pittsburgh, PA (KPIT), launched 12:00Z, 9.4 hours before the alert went out and 120 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 flash flood 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 flash flood warning went out at Jul 7, 4:19 PM EDT, 1 hour 4 minutes earlier.

Area forecast discussion, Jul 7, 4:19 PM EDT, 1 hour 4 minutes before

Area Forecast Discussion
National Weather Service Cleveland OH
419 PM EDT Sun Jul 7 2019

.SYNOPSIS...
A remnant frontal boundary remains across the area early this
morning, but will sink south with time today. High pressure will
be positioned just north of the area for tonight and Tuesday.
This high will shift east Wednesday and allow for a low pressure
system to track across the Midwest and Great Lakes Wednesday
into Thursday.

&&

.NEAR TERM /THROUGH MONDAY NIGHT/...
Last push of showers and scattered thunderstorms will be clearing
the area to the south and east through the early evening. Skies
will clear from the north as the drier air is pulled south on
the back side of a mid-level wave passing east of the area.
Given the lower dewpoints advecting into the area overnight, not
expecting to see fog despite the heavy rain that fell this
afternoon but that will be something to watch. Did raise min
temperatures by a degree or two overnight given the remaining
moist conditions late this afternoon.

Lakeshore Flood Warnings will continue into tonight. See the
marine discussion for additional details.

Monday will feature overall pleasant weather with lower humidity as
high pressure builds southeast into the area. Skies will be mostly
sunny with near seasonal temperatures.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
Upper level ridging over the eastern CONUS along with a surface high
pressure should keep the forecast rather mild on Tuesday. As both
the features move to the east, southerly flow will advect warm,
moist air into the region on Wednesday, allowing scattered
thunderstorms to develop in an airmass with moderate instability. An
upper level trough over the upper midwest move cross the Great Lakes
region late Wednesday night, with an associated cold front forcing a
line of showers and thunderstorms through the area late Wednesday
night into Thursday morning. Even though this line of storms is
expected to move through at an unfavorable period, models are
showing enough instability collocated with moderate shear, which
means there will be potential for isolated severe weather.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
Precipitation chances will linger in the eastern part of our CWA on
Thursday as the cold front continues to move through. Northwest flow
aloft and lingering moisture could support a few showers in eastern
areas early Friday before another area of high pressure builds in
for the weekend. This moisture starved feature will support a dry
weekend with seasonable temperatures.

&&

.AVIATION /18Z Sunday THROUGH Friday/...
Showers with a few thunderstorms have developed from FDY-MFD-YNG
and points south. Showers have been efficient rain producers,
lowering visibilities to IFR. Rain is expected to gradually
shift to the south with time this afternoon with ceilings
improving to VFR at all terminals by this evening. Clouds will
attempt to scatter out overnight into Monday morning from north
to south. Much drier air will start to work into the area from
the north so did not include any patchy fog for late tonight.
This will be something to monitor however, especially if winds
are light and skies clear out at locations that received heavy
rain this afternoon.

For today, winds will be strongest for lakeshore terminals with
northeast winds of 10-15 knots, gusting to 25 knots at times.
Northeasterly winds can be expected elsewhere but the higher
gusts are not expected.

OUTLOOK...Non-VFR possible later Wednesday/Wednesday night in
scattered showers and thunderstorms.

&&

.MARINE...
Northeast winds of 10 to 20 knots will continue through the next few
hours before beginning to decline later this evening. This will
result in continued lakeshore flooding for lakeshore communities
along the western basin, small craft advisory conditions for most
nearshore zones, and hazardous swimming conditions through most of
the day today. As the surface high pressure slides south, the
northeast flow will decrease allowing for gradually improving
conditions. High pressure will support weak synoptic winds through
Wednesday with a lake breeze anticipated each afternoon. A stronger
northern stream low pressure system will drive a front through the
lake late Wednesday into early Thursday morning.
