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 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
Albany, NY (KALY), launched 12:00Z, 7.9 hours before the alert went out and 175 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.

STILL MOSTLY CLOUDY THROUGH THE DAY THOUGH PERHAPS SOME PEEKS OF

TROF FINALLY SLIDES EAST AFTER KATIA HAS MOVED OUT OF THE WAY.
ALL EYES ON KATIA STILL FOR THE EXTENDED AND A CHANGE IN TRACK

WELL...ESPECIALLY WITH TIMING OF FRONT THAT ENDS UP STUCK OVER
THE AREA ON WEDNESDAY AND INTO THURSDAY.
