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 Jackson, MS wrote its last area forecast discussion before this severe thunderstorm warning went out at May 21, 9:33 PM CDT, 16 minutes earlier.

Area forecast discussion, May 21, 9:33 PM CDT, 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
933 PM CDT MON MAY 21 2012

.UPDATE...CONVECTION CONTINUES ACROSS THE AREA...ALTHOUGH IT IS MORE
ISOLATED AT THIS POINT. THE STEAM IS FINALLY GIVING OUT AND THE
STORMS ARE WEAKENING...BUT A FEW MAY PULSE UP OVER THE NEXT HOUR OR
SO. THERE ARE STILL A FEW POCKETS OF INSTABILITY...GENERALLY OVER THE
DELTA...WHERE DEWPOINTS ARE HIGHER AND IT WAS WARMER TODAY. THE
SOUTHWEST PORTIONS OF THE AREA ALSO HAD A LITTLE INSTABILITY
LEFT...WHERE STORMS WERE MOVING ACROSS NORTHEAST LOUISIANA INTO
SOUTHWEST MISSISSIPPI. RUC ALSO SUGGESTING THERE MAY BE A SUBTLE WAVE
AROUND 850 PASSING THROUGH THE SOUTHWEST WITH SOME 20-25KT NORTHWEST
WINDS FEEDING INTO THE STORMS. ANTICIPATING THE THUNDERSTORMS TO
DIMINISH THROUGH MIDNIGHT. MAINTAINED ISOLATED SHOWERS AND
THUNDERSTORMS FOR MUCH OF THE AREA THROUGH MIDNIGHT AND REDUCED IT TO
THE SOUTH AND EAST THROUGH EARLY MORNING.

TWEAKED HOURLY VALUES TO ACCOUNT FOR WARMER TEMPERATURES AND TO
ADJUST DEWPOINTS. RAISED OVERNIGHT LOWS A DEGREE OR TWO...GUIDANCE
SUGGESTED THINGS WOULD BE NEAR 60 FOR MUCH OF THE AREA. OVERALL THE
FORECAST WAS GOOD. NO NEED FOR ANY REAL CHANGES. MAY HAVE TO UPDATE
AGAIN BEFORE MIDNIGHT. WILL SEND ZONES SHORTLY.

&&

.AVIATION...ISOLATED SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS
THE AREA FOR THE NEXT FEW HOURS. HEZ WILL BE THE ONLY STATION
IMPACTED TONIGHT.THERE MAY BE A FEW SHOWERS NEAR JAN THROUGH MIDNIGHT
ALSO. OTHERWISE...SKIES WILL CONTINUE TO CLEAR FROM THE NORTHWEST.
VFR CONDITIONS WILL PREVAIL THROUGH THE FORECAST PERIOD.
