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.

.UPDATE...
UPDATED ZONES TO UP POPS AREAWIDE AND TO ADD TORNADO WATCH FOR MILAM
AND ROBERTSON COUNTIES...PER COORDINATION WITH SPC. HOWEVER...
ONGOING AND FUTURE FLOODING APPEARS TO BE THE MAJOR THREAT FOR OUR
SOUTHERN ZONES TODAY...WITH TRAINING TORRENTIAL RAINS THERE. IF THIS
MORNINGS THUNDERSTORM COMPLEX DOES NOT HOSE THE ENVIRONMENT TOO
MUCH...THE COLD FRONT TO THE NORTHWEST MAY SET UP ADDITIONAL MAJOR
PROBLEMS IN AREAS WHICH HAVE ALREADY RECEIVED VERY HEAVY RAINS THIS

645 AM CDT
AVIATION WEATHER CONCERNS THIS MORNING WILL BE PRIMARILY MVFR
CEILINGS. HOWEVER...SOME TEMPO THUNDER IN WACO WILL BE NECESSARY
BASED ON CURRENT RADAR TRENDS. CEILINGS THIS AFTERNOON SHOULD LIFT
TO NEAR OR ABOVE 3000 FT AROUND MIDDAY.  THUNDERSTORM CHANCES WILL
INCREASE ACROSS THE METROPLEX TAF SITES THROUGH THE DAY...WE ARE
ANTICIPATING THE ACTIVITY IN THE SOUTH TO WEAKEN ONCE THE LOW LEVEL
JET DECREASES...THEREFORE WILL NOT INCLUDE THUNDER UNTIL THIS
EVENING (AROUND 2Z) WHEN THE COLD FRONT APPROACHES THE NORTHWEST
COUNTIES.  WE WILL HAVE TO KEEP A CLOSE EYE ON THE STORMS TO THE
SOUTH FOR POSSIBLE IMPACT ON THE METROPLEX TAF SITES LATER THIS
MORNING AND UPDATE IF NECESSARY.   FROPA WILL BE DIFFICULT DUE TO
THE AMOUNT OF CONVECTION EXPECTED AND MASKING BY OUTFLOW
BOUNDARIES...SO WILL KEEP NORTH WIND SHIFT AROUND 6 Z AT THE
METROPLEX SITES AND 8 Z AT WACO.  THUNDERSTORMS SHOULD CONTINUE
OVERNIGHT AND END JUST BEFORE BEFORE SUNRISE.  79

NW ZONES THIS AFTERNOON. SPC SLIGHT RISK FOR THIS AREA...WHERE
TIMING OF INITIAL CONVECTION WILL COINCIDE WITH MAXIMUM DAYTIME
HEATING. WITH ABUNDANT LOW-LEVEL MOISTURE AND CONSIDERABLE MID-LEVEL
LAPSE RATES...SEVERE POTENTIAL EXISTS DESPITE MINIMAL SPEED SHEAR.
DIRECTIONAL SHEAR WILL BE AT A PRIME NEAR FROPA...BUT TIMING WILL BE
OVERNIGHT FOR MUCH OF CWA. HEAVY RAIN IS STILL A CONCERN WITH
PREFRONTAL TRAINING...BUT EXPECT DECENT MOTION OF BOTH INDIVIDUAL
