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, 9.3 hours before the alert went out and 82 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 Jun 29, 3:18 PM EDT, 1 hour 58 minutes earlier.
Area forecast discussion, Jun 29, 3:18 PM EDT, 1 hour 58 minutes before
Area Forecast Discussion National Weather Service Cleveland OH 318 PM EDT Sat Jun 29 2019 .SYNOPSIS...A cold front will move south of the forecast area overnight. High pressure will build over the region on Sunday. && .NEAR TERM /THROUGH SUNDAY NIGHT/... A cold front will move south across the forecast area overnight. Showers and thunderstorms will continue to develop this afternoon and evening in advance of this system. The bulk of the activity will remain over Northeast Ohio and Northwest PA but a scattered shower or thunderstorm is possible anywhere in the forecast area. The front will become nearly stationary south of the Ohio River Valley overnight. High pressure will briefly build over the region on Sunday bringing dry, clear and cooler conditions. Any system will approach the forecast area from the west late Sunday night. A few showers are possible in the western areas towards daybreak Monday. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... A weak cold front will approach the area on Monday with increasing chances of thunderstorms through the day. The best chances look to be during the evening with some jet energy rounding the top of the ridge. Cant rule out the potential for a few severe thunderstorms. Cold front will attempt to move south of the region Monday morning but it may end up being located across western Ohio. This may end up causing a few thunderstorms to develop across NW Ohio as we see additional ripples of jet energy round the top of the ridge. 5H heights increase in the short term so we will warm back up with above average temperatures returning. May have to watch heat index values Monday afternoon with NW Ohio approaching 100. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... More of the same in the long term with weak frontal boundaries influencing the area along with lake breezes and outflow from convection. The upper level ridge will fluctuate in strength over us which will bounce the thunderstorm coverage from isolated to scattered each day. Temperatures will remain above seasonal averages. && .AVIATION /18Z Saturday THROUGH Thursday/... Scattered showers and thunderstorms are beginning to develop this afternoon as a cold front drifts south over the forecast area. Cloud bases around 4-5kft. The models indicate an increase in convection particularly over the central and eastern sections of the area within the next few hours. I will place VCTS in many TAF locations ~ 20Z to 24Z as confidence in the exact location will be difficult. After 00Z the convection will slide to the south and high pressure will build over the region. Westerly winds will shift to the northwest as this front passes TAF locations this evening. OUTLOOK...Non-VFR possible with isolated to scattered thunderstorms that develop Monday afternoon through Wednesday. && .MARINE... A cold front will sag southward across the lake overnight with westerly winds becoming north. Winds reach 15 knots for several hours Sunday morning which may build waves to 2 to 4 feet from Vermilion to Ripley. Likely the highest from Avon to Geneva-on-the- lake. High pressure then takes control of the region Sunday night into Monday with light winds. Another weak frontal boundary will cross the lake on Monday night. && .CLE WATCHES/WARNINGS/ADVISORIES...
