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 (KAGC), launched 12:00Z, 8.7 hours before the alert went out and 68 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 Pittsburgh, PA wrote its last area forecast discussion before this flash flood warning went out at May 5, 2:12 PM EDT, 2 hours 30 minutes earlier.
Area forecast discussion, May 5, 2:12 PM EDT, 2 hours 30 minutes before
Area Forecast Discussion National Weather Service Pittsburgh PA 212 PM EDT Fri May 5 2017 .SYNOPSIS... Low pressure will maintain rain chances and colder temperatures through the weekend. && .NEAR TERM /THROUGH TONIGHT/... A filling mid-level low will continue to eject northeastward during through the evening, pushing its associated dry slot through the eastern two-thirds of the CWA. This has allowed for substantial warming across western PA/northern WV, such that convective temperatures are being reached or will be reached shortly. Mesoanalyses have thus started to indicate CAPE development in the drying area, which will only spread over the next few hours. With enhancing southeasterly shear, showers and thunderstorms should start to develop over N WV/W MD/far SW PA and track north-northeastward into the early evening. The SPC has outline this area with a marginal risk, and this seems justified given the cooling mid-levels and strong low-level lapse rates. Going into tonight, the reorganizing mid-level trough axis remains generally positioned around the WV panhandle. The consensus favors elevated instability remaining ahead of the mid-level trough axis with a fair amount of convective precipitation during the overnight hours. Thunder probabilities will thus remain enhanced through the night. Fries && .SHORT TERM /SATURDAY THROUGH MONDAY/... The mid-level low will continue to linger over the area into the weekend with a second low dropping southward from Hudson Bay. Those two lows will have a little bit of Fujiwara interaction before generally congealing into one deeper low over the northeastern U.S. This will allow for very cold air aloft to continue showery conditions into the early half of the weekend with a bit drier northwesterly flow beginning thereafter. Layer RH values should begin to fall off by Sunday night such that some clearing will begin to bring in the chances of frost, as well. Temperatures look to remain below normal through the period. Fries && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... An upper level low will continue to spin near the northeastern coast of the U.S. through the long term period. This will keep northwesterly flow ingrained over the area and temperatures below normal throughout. However, with a continental air mass in control, chances for precipitation will remain below climatology, as well. Fries && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... Large low pressure system will continue Dry slot is clearing/scattering out lower ceilings that plagued much of the day. This area should begin to fill in with altocu through the early evening. Elsewhere, lower ceilings have held steady over DUJ/FKL and ZZV. Showers and thunderstorms expected to develop over the east, drifting north/northwestward this evening. These could lead to temporary restrictions and contain some gusty winds. The low will gradually shift overhead tonight, bringing with it lower ceilings and rain showers. IFR conditions expected to linger well into Saturday with little improvement through midday. Surface winds will generally remain variable until the low passes tonight. .Outlook... Restrictions are likely through the weekend as an upper trough remains situated over the region. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. &&
