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

Fort Worth, TX (KFWD), launched 12:00Z, 3.4 hours before the alert went out and 202 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.

Area forecast discussion, Oct 9, 7:01 AM CDT, 3 hours 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
701 AM CDT FRI OCT 9 2009

.AVIATION...

FOR THE 12Z TAFS...NUMEROUS RAIN SHOWER ACTIVITY WILL CONTINUE
OVER TAF SITES THRU MUCH OF THE MORNING HOURS. GREATEST
UNCERTAINTY IN THE FORECAST IS WHAT THE CIGS WILL DO AFTER RAIN
SHOWER ACTIVITY HAS ENDED. MVFR CIGS LOOK LIKELY WHILE RAIN SHOWER
ACTIVITY PERSISTS...AND AFTER THAT...LOW END VFR CIGS ARE
INDICATED IN NAM/GFS FORECAST SOUNDING. UPSTREAM OBSERVATIONS
INDICATE STRATUS CONTINUES WELL INTO OK EARLY THIS MORNING...BUT
IT IS UNCERTAIN HOW DAYTIME HEATING WILL AFFECT THIS. FOR NOW HAVE
GONE WITH THE OPTIMISTIC FORECAST SOUNDINGS...BUT IF UPSTREAM CIGS
DO NOT LIFT WITH DAYTIME HEATING MVFR STRATUS MAY HAVE TO BE
CONTINUED THROUGHOUT THE DAY. OTHERWISE WOULD EXPECT CIGS TO CLEAR
OUT AROUND SUNSET AS DRIER CANADIAN AIRMASS FILTERS SOUTH INTO
NORTH TX.

TODAY...MVFR CIGS...WIDESPREAD RAIN SHOWER ACTIVITY THRU THE
MORNING HRS.

TONIGHT...VFR...EXPECTING STRATUS DECK TO DISSIPATE AFTER SUNSET.

SATURDAY...VFR.

.PREV DISCUSSION...
315 AM
LITTLE CHANGE TO TODAY/S SYSTEM TIMING...WITH PRECIP LIKELY OUT
OF CWA BY 7 PM. WILL CONTINUE FLASH FLOOD WATCH...AS 35-45 MPH LLJ
STILL FEEDING MOISTURE INTO THE STORMS. BY MID MORNING WE SHOULD
BE ABLE TO TRIM THE BACK EDGE OF THE WATCH AS THE SYSTEM
PROGRESSES SOUTHEAST. HAD GONE BELOW MOS YESTERDAY FOR
TEMPERATURES FRIDAY AND SATURDAY...BUT THIS MODEL RUN SEEMS TO BE
COOL ENOUGH FOR DAY ONE AND TWO. BY SUNDAY MOS SEEMS TOO WARM
AGAIN...WITH ANOTHER COLD SHOT OF AIR EXPECTED AND A WAVE
APPROACHING THAT SHOULD INCREASE CLOUDS. WENT COOLER...WITH 50S
NORTHWEST TO 70S SOUTHEAST.

HAVE INCREASED POPS FOR SUNDAY EVENING THROUGH TUESDAY MORNING AS
MODELS SEEM TO AGREE ON A WAVE MOVING OVER THE FRONT PROVIDING
ISENTROPIC LIFT AND RAINFALL. AFTER TUESDAY...MODELS DIVERGE BUT
BOTH GFS AND ECMWF CONTINUE AN UNSETTLED PATTERN. HAVE LOW
CONFIDENCE...AND HAVE TRENDED NEXT WEEK TEMPS/POPS TO A SORT OF
MIDDLE GROUND BETWEEN THE TWO...AND HAVE INDICATED LOW POPS
AS WELL.

ECMWF BRINGS ANOTHER STRONG COLD FRONT ACROSS THE AREA NEXT
FRIDAY...BUT GFS HOLDS IT BACK UNTIL SATURDAY AND THE TIMING WILL
HAVE A DRAMATIC EFFECT ON FRIDAY/S HIGHS AND SATURDAY/S LOWS. AT
THIS TIME I WENT WITH THE FASTER FROPA...BUT AGAIN...LOW
CONFIDENCE.     84
