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.

Topeka, KS (KFOE), launched 00:00Z, 9.0 hours before the alert went out and 142 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 Kansas City, MO wrote its last area forecast discussion before this flash flood warning went out at May 17, 3:07 AM CDT, 52 minutes earlier.

Area forecast discussion, May 17, 3:07 AM CDT, 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
307 AM CDT Sun May 17 2015

.DISCUSSION...
Issued at 307 AM CDT SUN MAY 17 2015

Trailing stratiform area of rainfall will continue to push east of
the forecast area this morning with most areas being dry by later
this morning or early this afternoon. Winds will be veered to the
southwest today with warm temperatures aloft working over the region.
Deep mixing into these temperatures should lead to highs in the low
to mid 80s. Despite the southwesterly surface flow and deeper mixing,
dewpoints still look to be in the upper 50s to lower 60s so it still
looks like relatively humid conditions will persist into this
afternoon. The cold front will then move through late in the evening
and then temperatures and dewpoints will drop with much more
comfortable conditions expected Monday. The high pressure responsible
for this cooler and drier airmass will continue to influence the
region through Tuesday. However, rainfall is expected to build into
the area overnight as an impulse moves out of the main longwave
trough over the west. Widespread shower activity is likely Tuesday
night into Wednesday as a result. Instability looks weak so only
isolated/embedded thunder is expected. The pattern looks to repeat
itself next weekend as low level flow becomes southerly ahead of a
robust upper level trough. With more persistent southerly flow,
greater instability should build so there will be better chances for
thunderstorms Friday into Saturday.

&&

.AVIATION...(For the 06Z TAFS through 06Z Sunday Night)
Issued at 1215 AM CDT SUN MAY 17 2015

Convective line will continue to push through the area overnight. The
main consideration at this point is continued rain showers with
nearby thunderstorms. Visibilities could diminish to MVFR at times,
but will improve as the night progresses. All activity should clear
out of the terminal sites early Sunday morning with improving
conditions through the day. Winds will veer to the southwest with
gusty conditions expected until sunset.
