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.

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.

Area forecast discussion, Oct 16, 3:52 AM CDT, 1 hour before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
352 AM CDT MON OCT 16 2006

.DISCUSSION...
TROPICAL RAINFALL IS FALLING ACROSS MUCH OF NORTHERN TEXAS THIS
MORNING...AND THIS WILL CONTINUE UNTIL THE VORT MAX (UPPER AIR
DISTURBANCE) SWEEPS ACROSS THE AREA THIS AFTERNOON. FOR THE DFW
AND WACO AREAS...RAINFALL IS LIKELY TO END ABOUT 18Z...OR MAYBE A
BIT SOONER. SOME LOCALIZED HIGH WATER PROBLEMS ARE POSSIBLE...BUT
THE FAST MOVING RAIN AND THUNDERSTORM CELLS SHOULD MOVE RATHER
QUICKLY...GIVEN THE STRONG WIND FLOW ALOFT.

CONDITIONS WILL WARM IN WESTERN AND CENTRAL PORTIONS OF THE AREA
AS CLOUDS BREAK THIS AFTERNOON. THERE IS A THREAT OF FOG
TONIGHT...BUT WE WILL LET THE NEXT FORECAST SHIFT DEDUCE WHERE AND
WHEN THIS MAY OCCUR. TEMPERATURES WILL WARM QUICKLY TUESDAY...AS
LOW LEVEL SOUTHWEST FLOW AND SUBSIDENCE OCCUR. THUS...WE HAVE
GONE ABOVE MOS HIGH TEMPERATURES ON TUESDAY.

A BLUSTERY COOL FRONT WILL MOVE THROUGH THE AREA WEDNESDAY
AFTERNOON AND EVENING. WE HAVE GREATLY LOWERED THE RAIN CHANCES
AND AMOUNTS...AS THE SYSTEM IS MOISTURE STARVED...AND WITHOUT MUCH
UPPER LEVEL SUPPORT. WE HAVE INCREASED RAIN CHANCES NEXT WEEKEND...AS
ANOTHER COOL FRONT ENCOUNTERS BETTER RETURN FLOW OF MOISTURE AND
HEAT. HOWEVER...WE HAVE KEPT POPS ON THE LOW SIDE...CONSIDERING
THAT THIS IS THE FIRST RUN THAT LOOKS LIKE A GOOD BET FOR SOME
RAINFALL.   #26
