What happened
The episode as NWS SHV wrote it up.
A shallow cold front began to shift southeast into Northeast Texas, Southeast Oklahoma, and Southwest Arkansas during the late afternoon and evening hours of the 1st, with a very warm, moist, and unstable air mass in place as an upper level disturbance ejected northeast across the Four State region. As a result, scattered strong to severe thunderstorms developed across these areas along and behind the front, which produced numerous reports of large hail and occasional reports of wind damage. An isolated report of a funnel cloud was also received, before these storms weakened during the late evening hours with the loss of heating, instability, and convergence along the frontal boundary.

.DISCUSSION...
THIS MORNING A COLD FRONT HAS MOVED INTO PARTS OF SOUTHWEST ARKANSAS
EXTREME SOUTHEAST OKLAHOMA...AND NORTHEAST TEXAS NEAR A HOT SPRINGS
TO DE QUEEN ARKANSAS AND IDABEL OKLAHOMA TO PARIS TEXAS LINE. THIS FRONT
EXTENDED INTO SURFACE LOW PRESSURE NEAR THE BIG BEND COUNTRY OF
WEST TEXAS. SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ALONG THE BOUNDARY
OVER SOUTHEAST OKLAHOMA NORTH INTO CENTRAL AND NORTHEAST ARKANSAS...AND
HAVE DEVELOPED ALONG AND NEAR THE BOUNDARY OVER NORTH AND CENTRAL TEXAS.
UPPER DISTURBANCES EJECTING AROUND THE BASE OF A TROUGH NEAR THE
FOUR CORNERS REGION AND OVER THE TOP OF A FLAT RIDGE OF HIGH
PRESSURE OVER THE CENTRAL GULF COAST STATES CONTRIBUTING TO THE
DEVELOPMENT OF STRONG TO SEVERE STORMS OVER TEXAS HEADING TOWARD
THE FOUR STATE REGION. WITH SOUTHERLY LOW LEVEL FLOW ON THE
SURFACE AND IN THE BOUNDARY LAYER AND A STRONG LOW LEVEL JET
FEEDING MOISTURE INTO THE AREA ACROSS AND ALONG THE BOUNDARY...EXPECT THE
SHOWERS AND THUNDERSTORMS TO INCREASE AND PRODUCE LOCALLY HEAVY
RAINFALL. THE FLASH FLOOD WATCH CONTINUED FOR NORTHEAST
TEXAS...SOUTHEAST OKLAHOMA...AND SOUTHWEST AND SOUTH CENTRAL
ARKANSAS THROUGH EARLY MONDAY. STORMS MOVING NORTHEAST NEAR AND
ALONG THE SURFACE BOUNDARY WILL HAVE THE POTENTIAL TO PRODUCE
STRONG AND DAMAGING WINDS...LARGE HAIL...AND LOCALLY HEAVY
RAINFALL...AND ISOLATED TORNADOES. THE SURFACE BOUNDARY WILL MOVE
SLOWLY SOUTH AND THEN LIFT BACK NORTH OVER THE EASTERN AND
NORTHERN END AS A SURFACE LOW ALONG THE COLD FRONT MOVES TO THE
NORTHEAST ALONG THE BOUNDARY. SHOWERS AND THUNDERSTORMS WILL
CONTINUE OVERNIGHT AND INTO MONDAY AS THE BOUNDARY MOVES OVER THE
AREA. AS THE SURFACE LOW MOVES TO THE SOUTHEAST OF THE FORECAST AREA
RAIN WILL CONTINUE TO RIDE OVER THE COLDER AIR ON THE BACK SIDE
KEEP RAIN CHANCES INTO THE DAY TUESDAY. BY LATE TUESDAY THE UPPER
TROUGH WILL SWING EAST BRINGING AN END TO THE PRECIPITATION
KEEPING THE FOUR STATE REGION ON THE COOL SIDE. SURFACE HIGH
PRESSURE WILL PROVIDE DRY WEATHER THROUGH THE LATE PART OF THE COMING
WORK WEEK WITH THE NEXT CHANCE FOR RAIN COMING INTO THE WEEKEND. /06/
&&
.AVIATION...
MVFR CIGS ARE EXPECTED TO SPREAD ACROSS MOST TAF SITES SUNDAY
MORNING WITH SOME ISOLATED IFR CONDITIONS POSSIBLE BEFORE CIGS BEGIN
TO LIFT BY 14Z. SCATTERED PREFRONTAL CONVECTION IS EXPECTED FOR MUCH
OF THE TAF PERIOD. THE FRONT WILL LIKELY BECOME QUASI-STATIONARY
BETWEEN THE I-30 AND I-20 CORRIDORS BY 00Z MONDAY. THE BULK OF THE
PRECIP WILL LIKELY BE CONFINED TO KTXK/KELD AND ADJACENT AREAS OF
EXTREME NE TX...SE OK...AND SW AR. TSTMS WILL LIKELY BE MORE
SCATTERED IN NATURE FARTHER SOUTH AT THE REMAINDER OF THE TERMINALS.
THE MAIN UPPER LEVEL TROUGH IS STILL FORECAST TO BE WELL WEST OF THE
AREA AT THE END OF THE TAF PERIOD...SO PERIODS OF SHRA/TSRA AND
ASSOCIATED MVFR/IFR CONDITIONS CAN BE EXPECTED WELL INTO MONDAY. SE
WINDS CAN BE EXPECTED AHEAD OF THE FRONT AND SHIFTING TO THE N AND
NE AS THE FRONT PASSES. /09/
