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.

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 20, 7:02 PM CST, 1 hour 34 minutes earlier.

Area forecast discussion, Nov 20, 7:02 PM CST, 1 hour 34 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE FORT WORTH TX
702 PM CST SUN NOV 20 2011

.UPDATE...
THE IMMEDIATE THREAT FOR SEVERE WEATHER IN NORTH TEXAS APPEARS TO
BE WANING AND THUS HAVE CANCELLED THE WATCH FOR ALL OF NORTH
TEXAS. EXPECT THAT SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS
WILL CONTINUE THROUGH THE NIGHT AND SOME OF THESE MAY PRODUCE
SMALL HAIL AND NUMEROUS CLOUD TO GROUND LIGHTNING STRIKES. THE 00Z
FWD SOUNDING SHOWS THE COLD FRONT TO BE CONFINED BELOW 925 MB OR
BELOW 3000 FT. ABOVE THE COLD FRONT THE ATMOSPHERE IS UNCAPPED AND
UNSTABLE BUT WEAK LAPSE RATES AND A LACK OF SIGNIFICANT
/UPWARD FORCING BEHIND THE FRONT IS LIKELY KEEPING THE SHOWERS
AND THUNDERSTORMS BELOW SEVERE LIMITS.

THE COLD FRONT IS MAKING AN IMPRESSIVE ADVANCEMENT SOUTH AND HAS
NOW PASSED THROUGH LAMPASAS AND PARTS OF NORTHERN BELL COUNTY. THE
WESTERN PORTION OF THE FRONT HAS MORE PUSH THAN THE EASTERN
SECTION AS THE FRONT THEN DRAPES TO THE NORTHEAST TOWARDS
CORSICANA AND EMORY. THE TEMPERATURE FORECAST FOR TONIGHT HAS BEEN
ADJUSTED BASED ON THIS LATEST POSITION BUT MAY NEED TO BE ADJUSTED
AGAIN DEPENDING ON HOW FAR SOUTH THE EASTERN PORTION ADVANCES.
WITH THE FRONT FARTHER SOUTH THAN PREVIOUS FORECAST...THIS COULD
AFFECT THE CONVECTIVE FORECAST FOR TOMORROW BUT WILL NOT BE MAKING
CHANGES AT THIS TIME.

82/JLD

&&

.AVIATION...
MULTIPLE AVIATION WEATHER CONCERNS THROUGH MONDAY AFTERNOON WITH
MVFR CEILINGS/VISIBILITIES EXPECTED THROUGH THE EVENING...BECOMING
IFR AFTER SUNRISE MONDAY AND REMAINING IFR UNTIL MID AFTERNOON.

A COLD FRONT...CURRENTLY NEAR A LAMPASAS...WACO...CORSICANA...TO
EMORY LINE...WILL REMAIN NEARLY STATIONARY OVERNIGHT AND LIFT
NORTHWARD ON MONDAY. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS
WILL BE POSSIBLE NEAR AND NORTH OF THE COLD FRONT OVERNIGHT WITH
STORM CHANCES INCREASING ON MONDAY AS THE FRONT LIFTS NORTH AND
LARGE SCALE LIFT INCREASES. THE BEST THUNDERSTORM CHANCES AT ALL
TAF SITES WILL BE MONDAY AFTERNOON/MONDAY NIGHT.

A NORTH/NORTHWEST WIND WILL PREVAIL AT ALL TAF SITES OVERNIGHT AT
SPEEDS BETWEEN 6 AND 12 KNOTS ALONG WITH SOME HIGHER GUSTS THIS
EVENING. THE WIND WILL SLOWLY TURN TO THE NORTHEAST/EAST ON MONDAY
AS THE FRONT BEGINS TO LIFT NORTHWARD AND EVENTUALLY BECOME
SOUTHEAST MONDAY AFTERNOON/EVENING.

.PREV UPDATE...
.UPDATE...

SEVERE THUNDERSTORM WATCH #893 UNTIL 05Z/11PM THIS EVENING FOR
AREAS FROM GRANBURY AND MARLIN...NORTHEAST TO BONHAM...PARIS AND
PALESTINE. UPDATES FORTH COMING. 75

&&

.PREV DISCUSSION... /ISSUED 157 PM CST SUN NOV 20 2011/

...SEVERE THUNDERSTORM POTENTIAL CONTINUES ACROSS PORTIONS OF NORTH
TEXAS LATER THIS AFTERNOON AND AGAIN ON MONDAY AFTERNOON AND
EVENING...

OVERALL...THIS AFTERNOONS FORECAST PACKAGE CONTINUES THE TRENDS
MENTIONED IN PREVIOUS FORECASTS OVER THE PAST SEVERAL DAYS. THE
COLD FRONT IS RUNNING SLIGHTLY AHEAD OF PREVIOUS TIMING...BUT
FAIRLY CLOSE TO THE NAM AND RUC MODEL SOLUTIONS. AT 145 PM IT
EXTENDS FROM PARIS TO CLEBURNE TO SOUTH OF COMANCHE.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS LATER THIS
AFTERNOON THROUGH MID/LATE EVENING AS FORCING FOR ASCENT ARRIVES
FROM THE WEST AND HELPS WEAKEN THE STRONG CAP AROUND 860MB. VERY
MOIST AND UNSTABLE AIR AHEAD OF THE COLD FRONT WILL PRODUCE CAPES
500-1200 J/KG THIS EVENING AND 700-1400 J/KG ON MONDAY. BULK SHEAR
0-6KM WILL BE IN THE RANGE OF 40-60 KTS BOTH DAYS ALONG WITH
HELICITY VALUES GREAT THAN 200 M2/S2. AS PREVIOUSLY STATED...LARGE
HAIL WILL BE THE PRIMARY SEVERE THUNDERSTORM THREAT FOLLOWED BY
DAMAGING WINDS AND BRIEF ISOLATED TORNADOES. AREAS TO WATCH FOR
QUICK TORNADOGENESIS ARE...WHERE SURFACE WINDS ARE BACKED AND
THOSE CELLS THAT MOVE NEAR AND ALONG THE COLD FRONT. HAVE ADDED
SEVERE WORDING TO THE ZONE PACKAGE IN THIS RELEASE.

THE SYSTEM SHOULD MOVE OUT OF NORTH TEXAS LATE TUESDAY AFTERNOON
WITH FAIR WEATHER FOR WEDNESDAY AND THANKSGIVING DAY. OUR NEXT
SYSTEM WILL ARRIVE FRIDAY WITH ANOTHER ROUND OF THUNDERSTORMS AND
BENEFICIAL RAINFALL FOR NORTH TEXAS. THIS SYSTEM WILL MOVE RIGHT
ON THROUGH THE REGION AND SHOULD BE OUT OF NORTH TEXAS LATE FRIDAY
NIGHT. AFTERWARD...IT WILL BE DRY WITH SEASONAL TEMPERATURES OVER
THE WEEKEND. 75
