Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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, 11.0 hours before the alert went out and 207 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 severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Fort Worth, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Nov 23, 4:50 PM CST, 8 minutes earlier.

Area forecast discussion, Nov 23, 4:50 PM CST, 8 minutes before

AREA FORECAST DISCUSSION...UPDATED FOR AVIATION
NATIONAL WEATHER SERVICE FORT WORTH TX
450 PM CST TUE NOV 23 2004

.AVIATION DISCUSSION...
AREA OF STORMS WEST AND SOUTHWEST OF DFW AREA WILL MOVE NORTHEAST
INTO THE AREA 00-01Z.  SOME OF THESE STORMS ARE SEVERE...BUT CURRENT
THINKING IS THE STORMS WILL DECREASE SOME AFTER SUNSET.  HOWEVER...I
STILL THINK THE STRONGEER STORMS WILL BE CAPABLE OF 40KT GUSTS IN
THE DFW AREA.  59

&&

.DISCUSSION...
TODAYS INITIAL ROUND OF CONVECTION...ASSOCIATED WITH LEADING UPPER
SPEED MAX AND INCREASINGLY DIFLUENT FLOW ALOFT...HAS NOW SHIFTED
INTO EAST TEXAS...WITH ONLY ISOLATED ACTIVITY REMAINING IN THE
EASTERN ZONES. HOWEVER...QG FORCING ASSOCIATED WITH UPPER LOW
APPROACHING KLBB HAS AIDED IN DEVELOPMENT OF ANOTHER ROUND OF
SHOWERS/THUNDERSTORMS...FROM KABI SWD TO KSJT/KDRT. THIS AREA OF
CONVECTION SHOULD EXPAND EASTWARD...AS IT COMES UNDER THE INFLUENCE
OF INCREASING DIVERGENCE ALOFT BENEATH LEFT EXIT REGION OF YET
ANOTHER 100-120KT UPPER SPEED MAX. GIVEN COLD TEMPERATURES ALOFT
ASSOCIATED WITH THIS SYSTEM...MARGINALLY SEVERE HAIL WILL BE
POSSIBLE WITH THE STRONGEST CELLS...AND SEVERE THUNDERSTORM WATCH
886 HAS BEEN POSTED FOR SWRN PORTION OF THE FORECAST AREA THROUGH
24/02Z.

THE UPPER LOW IS PROGGED TO ACCELERATE EASTWARD AND DEEPEN
OVERNIGHT...AS UPPER SPEED MAX WORKS ITS WAY TO EASTERN FLANK OF THE
SYSTEM. RESULTANT SURFACE CYCLOGENESIS WILL ALLOW STRONGER WESTERLY
BOUNDARY LAYER FLOW TO SPREAD ACROSS THE AREA THIS EVENING...BEFORE
STRONG COLD ADVECTION BEGINS ON WEDNESDAY MORNING. SOME LINGERING
-RA IS POSSIBLE ACROSS THE RED RIVER VALLEY ON WEDNESDAY MORNING.
OTHERWISE...EXPECT A COOLER DAY ALONG WITH BRISK NORTHWEST WINDS. AS
SURFACE RIDGE AXIS SETTLES ACROSS NORTH TEXAS ON THURSDAY MORNING...
MINIMUM TEMPERATURES WILL LIKELY FALL BELOW FREEZING IN MANY
AREAS...ESPECIALLY NORTHEAST/NORTH AND WEST OF THE DFW METROPLEX.
PLEASANT WEATHER WILL PERSIST FOR THE REMINDER OF THURSDAY AND
FRIDAY...AS MID/UPPER FLOW REGIME REMAINS LARGELY ZONAL ACROSS NORTH
TEXAS.

A WEAK VORT MAX WILL LIKELY SPREAD CLOUDS ACROSS THE AREA BEGINNING
ON FRIDAY NIGHT...BUT QUESTIONABLE DEGREE OF MOISTURE RETURN AND
NORTHERN TRACK OF SYSTEM PRECLUDE MENTIONING POPS ATTM. THE LATEST
ECMWF/GFS ARE IN GENERAL AGREEMENT ON A STRONGER UPPER SYSTEM
APPROACHING THE AREA ON MONDAY/TUESDAY...AND HAVE MAINTAINED THE
INHERITED CHANCE POPS FOR THIS PERIOD...AS ANOTHER STRONG FRONT
LOOKS TO PUSH ACROSS THE AREA ON MONDAY.
