What happened

The episode as NWS FWD wrote it up.

Severe thunderstorms producing large hail erupted during the afternoon hours in a highly unstable environment along a dryline west of Fort Worth. These storms eventually merged into an HP supercell that produced hail up to the size of softballs. Additional severe thunderstorms developed in the evening along a cold front moving across the Red River. Later in the night as the storms were weakening, a heatburst occurred near and west of Paris. The AWOS in Paris reported a 67 mph wind gust while the temperature rose 11 degrees.

What forecasters said that day

.DISCUSSION...
LITTLE CHANGE TO PREVIOUS FORECAST THIS PACKAGE...AS WE AWAIT TO SEE
IF INTENSE HEATING JUST ALONG FRONTAL WAVE JUST OFF NW COUNTIES CAN
CONTINUE TO WEAKEN CINH/CONVECTION INHIBITION AND ALLOW FOR RAPID/

...WHERE MSAS MOISTURE CONVERGENCE HAS BEEN INTENSIFYING WITH SOME
SLOW BACKING OF SFC WINDS TO SELY AT BRECKENRIDGE/BOWIE/MINERAL
WELLS/AND GRAHAM. 0-1KM/0-6KM SHEAR WILL BE AMPLE ON SRN FRINGE OF
WLY/ZONAL FLOW ALOFT ACROSS THIS AREA TO KEEP STORMS GOING AFTER
