What happened

The episode as NWS SHV wrote it up.

A potent...upper level short wave accompanied a prefrontal feature during the afternoon hours of November 29th across north central Louisiana. These thunderstorms developed in a weakly unstable airmass across the region. However...there was strong wind shear present...especially in the lowest 3 kilometers of the atmosphere. A broken line of thunderstorms developed across east central Texas into northwest Louisiana along the prefrontal trough axis. These thunderstorms quickly became supercells. One of these storms produced a significant tornado in Winn Parish which traveled northeast and dropped again in southern Ouachita Parish. Other storms downed powerlines in northwest Louisiana and minor flooding problems.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NATIONAL WEATHER SERVICE SHREVEPORT LA
300 PM CST MON NOV 29 2010

.DISCUSSION...
THE REMAINDER OF THE AFTERNOON AND INTO THIS EVENING WILL BE
SOMEWHAT ACTIVE FOR PORTIONS OF THE FOUR STATE REGION.  RADAR
IMAGERY CURRENTLY SHOWS SCATTERED SHOWERS AND THUNDERSTORMS OVER THE
EASTERN HALF OF THE CWFA...WITH SOME OF THE STORMS BECOMING
SEVERE AND SHOWING SIGNS OF ROTATION. MUCH OF THE CWFA WHICH
CURRENTLY HAS CONVECTION IS UNDER A TORNADO WATCH UNTIL 03Z.
SURFACE ANALYSIS THIS AFTERNOON SHOWS THE MAIN SURFACE LOW IS
LOCATED OVER NORTHWEST MO/SOUTHWEST IA WITH A COLD FRONT TRAILING
SOUTH INTO THE NORTHWESTERN CORNER OF THE CWFA. THE FRONT HAS
SLOWED SOMEWHAT...BUT SHOULD REACH THE CENTRAL PORTIONS OF THE
CWFA BY AROUND 00Z. A SECONDARY COLD FRONT IS LOCATED TO THE
NORTHWEST OVER CENTRAL OK AND ACROSS THE TX PANHANDLE. A WARM
FRONT HAS MOVED NORTHEAST INTO THE SOUTHWESTERN HALF OF THE CWFA.
THE MOST CONVECTION IS OCCURRING ALONG AND SOUTH OF THIS WARM
FRONT THIS AFTERNOON. WATER VAPOR IMAGERY THIS AFTERNOON SHOWS A
DEEP TROUGH MOVING ACROSS THE PLAINS STATES.

SEVERE STORMS WITH DAMAGING WINDS...HAIL AND POSSIBLE TORNADOES WILL
CONTINUE TO BE POSSIBLE FOR THE EASTERN HALF OF THE CWFA THIS
AFTERNOON AND EVENING.  THE THREAT WILL BE DIMINISHING FROM WEST TO
EAST DURING THE EARLY AND MID EVENING HOURS. IN THE
MEANTIME...DEWPOINTS HAVE BEEN RISING QUICKLY SOUTH OF THE WARM
FRONT TODAY.  THIS HAS COMBINED WITH PLENTY OF SHEAR OVER THE CWFA
TO ALLOW FOR THESE STORMS TO DEVELOP.  THESE CONDITIONS ARE EXPECTED
TO CONTINUE AS WE MOVE INTO THE EARLY EVENING HOURS.  THE THREAT
SHOULD DIMINISH BY AROUND MIDNIGHT FOR THE FOUR STATE REGION.  THE COLD
FRONT IS EXPECTED TO REACH THE CENTRAL PORTIONS OF THE FOUR STATE
REGION BY AROUND 00Z...AND THE EASTERN FRINGES OF THE CWFA BETWEEN
04-07Z...IF NOT A LITTLE SOONER. THE RAIN IS EXPECTED TO PUSH EAST
OF THE CWFA BY SUNRISE ON TUESDAY.

A COOLER AND DRIER AIRMASS WILL SETTLE OVER THE FOUR STATE REGION
FOR THE MIDDLE OF THE WORK WEEK.  HIGHS ON TUESDAY ARE NOT
EXPECTED TO RISE OUT OF THE 50S...WITH MANY LOCATIONS IN THE NORTH
REMAINING IN THE LOWER 50S. CONDITIONS WILL BE GUSTY OVER THE CWFA
ON TUESDAY. AS OF NOW...IT LOOKS AS IF WINDS WILL REMAIN JUST BELOW
LAKE WIND ADVISORY CRITERIA.  BUT WILL LET THE NEXT SHIFT MONITOR TO
SEE IF ONE WILL BE NEEDED FOR TUESDAY.

THE SURFACE HIGH WILL BEGIN TO WORK ITS WAY INTO THE REGION FOR
TUESDAY NIGHT.  THIS WILL GIVE ANOTHER COLD NIGHT FOR THE REGION
WITH LOWS EXPECTED TO DROP INTO THE 20S ACROSS MOST OF THE AREA.
THE HIGH WILL BECOME MORE CENTERED OVER THE REGION DURING THE DAY
WEDNESDAY...ALLOWING FOR SLIGHTLY WARMER HIGHS IN THE LOWER 60S.
THE HIGH IS EXPECTED TO BEGIN SHIFTING TO THE EAST OF THE AREA
WEDNESDAY NIGHT THROUGH THE END OF THE WORK WEEK...WHICH SHOULD
BRING A GRADUAL WARM UP THROUGH THE END OF THE WEEK. LOWS SHOULD
WARM ABOVE FREEZING FOR THE MAJORITY OF THE CWFA BY THURSDAY NIGHT.

TOWARD THE WEEKEND...A SHORTWAVE IS EXPECTED TO MOVE ACROSS THE
NORTHERN STATES.  THIS WILL BRING A WEAK COLD FRONT TOWARD THE FOUR
STATE REGION FOR SOMETIME DURING THE LATE PART OF THE WEEKEND AND
INTO EARLY NEXT WEEK. THERE ARE STILL SOME DISCREPANCIES BETWEEN
MODELS AND RUNS ON THIS SYSTEM. FOR NOW WILL CONTINUE TO STICK WITH
GUI VALUES FOR POPS AND TEMPS THROUGH THE EXTENDED. /22/

&&

.AVIATION...
COLD FRONT HAS SLOWED A BIT NOW THAT IT HAS STARTED TO MOVE INTO THE
FORECAST AREA.  THE FRONT SHOULD REACH THE KTXK...KSHV...AND KLFK
LINE AROUND 30/0000 UTC...THEN KELD AND KMLU BETWEEN 30/0300-0600
UTC.  EXPECT IFR FLIGHT CATEGORIES IN VICINITY OF SHRA/TSRA ALONG
AND AHEAD OF THE FRONT...WITH WIDESPREAD MVFR CIGS/VSBYS OTHERWISE.
FLIGHT CATEGORIES SHOULD IMPROVE IN WAKE OF THE FRONT...AS DRIER AIR
MOVES INTO THE REGION.  WINDS WILL BE SE-S 10-15 KTS /GUSTY IN
VICINITY OF TSRA/ AHEAD OF THE FRONT...THEN BECOME W-NW AS THE FRONT
MOVES ACROSS THE REGION.  /D. BUTTS/

Numerous trees were snapped near the intersection of Collier and Water Well Roads. The tornado then crossed Gum Springs Road, where it completely destroyed one well-built two story brick home and an adjacent brick garage. The home was approximately 4000 sq. ft in size, built in 1997, and its destruction was the basis of the EF-4 rating. Many of the nearby trees were completely snapped, with several near the home snapped off at the base. One single wide mobile home was also destroyed, with its remnants blown into a wooded area about 300 yards away. Another nearby home was moderately damaged, while two other homes suffered minor damage. The tornado then crossed into an open field, before entering a heavily wooded area, traveling northeast across Highways 84 and 167, where sporadic minor tree damage was observed just west and north of Winnfield.
