What happened

The episode as NWS SHV wrote it up.

Discrete supercell thunderstorms developed during the late afternoon hours across North Central Texas. These storms moved eastward into Northeast Texas during the late evening and overnight hours of the 18th. By the time the storms moved into Northeast Texas, the storms had evolved into a broken line of storms...producing damaging wind gusts and large hail. This line of storms continued to propagate eastward into Northwest Louisiana and produced sporadic wind damage in the form of downed trees.

What forecasters said that day

.AVIATION...
ACTIVE EVENING TONIGHT WITH A COMPLEX OF STORMS WHICH MOVED OUT OF
CENTRAL TEXAS AND IS NOW AFFECTING OUR NE TX TERMINALS AND THE SHV
TERMINAL HERE SHORTLY. A STABLE ATMOSPHERE WAS PRESENT EAST OF
THIS COMPLEX OF STORMS AS WE CONTINUE TO SEE PATCHY FOG FORMING
ACROSS PORTIONS OF SOUTHWEST ARKANSAS AND NORTHERN LOUISIANA LATE
THIS EVENING.

FEEL LIKE THE LINE OF STORMS WILL CONTINUE TO MAKE SLOW BUT STEADY
PROGRESS EASTWARD AND SHOULD AT THE VERY LEAST AFFECT THE
TXK/SHV/LFK TERMINALS BEFORE DISSIPATING. FOR THIS REASON...HAVE
LEFT OUT MENTION OF WX IN THE ELD/MLU TERMINALS. INSTEAD...MAY
HAVE TO DEAL WITH IFR CEILINGS AND/OR VSBY PROBLEMS ACROSS THESE
TERMINALS THROUGH AT LEAST MID MORNING.

THE BULK OF SUNDAY APPEARS TO BE VFR AS A STRONG PRESSURE GRADIENT
WILL DEVELOP FROM WEST TO EAST ACROSS OUR REGION. THE RESULT WILL
BE VEERING SOUTHWEST WINDS WITH GUSTS AS HIGH AS 25KTS ACROSS OUR
NE TX TERMINALS BY LATE MORNING THROUGH THE AFTERNOON. A
PREFRONTAL TROUGH WILL COME EASTWARD QUICKLY LATE SUNDAY AFTERNOON
AND EVENING WITH STRONG TO SEVERE STORMS LIKELY ALONG THIS TROUGH.
HAVE INTRODUCED VCTS FOR THIS ACTIVITY EFFECTING OUR TERMINALS
LATE IN THE AFTERNOON AND THROUGH THE EVENING HOURS. A FRONTAL
BOUNDARY WILL CATCH UP TO THE CONVECTION AND WILL SHIFT WINDS
AROUND TO A WESTERLY DIRECTION AND EVENTUALLY NORTHWEST JUST
BEYOND THIS TAF CYCLE.
