The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Mar 10, 2:32 PM CST, 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
232 PM CST WED MAR 10 2010

.DISCUSSION...
ACTIVE WEATHER ALONG AND NORTH OF THE I-30 CORRIDOR OF NE TX THIS
AFTERNOON WITH STORMS FORMING ALONG A PREFRONTAL TROUGH THAT HAS
BECOME SEPARATED FROM THE MAIN DRYLINE/FRONT WHICH EXTENDS FROM
DURANT OKLAHOMA ONTO NEAR TERRELL...CORSICANA AND SAN ANTONIO
TEXAS. LEADING LINE OF SEVERE THUNDERSTORMS FROM CLARKSVILLE TEXAS
SOUTHWARD TO NEAR TYLER TEXAS HAVE BEEN PROLIFIC HAIL PRODUCERS
THUS FAR WITH SOME REPORTS OF FUNNEL CLOUDS REPORTED EARLIER NEAR
TALCO TEXAS. IT REMAINS TO BE SEEN HOW MUCH FARTHER SOUTH THIS
LINE CAN DEVELOP BEFORE THE DRYLINE/FRONTAL CONVECTION CATCHES IT
AND BECOMES THE MAIN PLAYER THROUGH THE EVENING HOURS TONIGHT.
LOW LEVEL HELICITY REMAINS WEEK AHEAD OF THE DRYLINE CONVECTION
BUT STILL CANNOT RULE OUT AN ISOLATED TORNADO ACROSS THE REGION
OVERNIGHT. STILL LOOKS LIKE HAIL WILL BE THE PRIMARY SEVERE
WEATHER THREAT WITH LOW WET BULB ZERO HEIGHTS AND AND STEEP MID
LEVEL LAPSE RATES.

GIVEN THE SPEED OF THE CONVECTION...HAVE GONE WITH LIKELY POPS
ACROSS MOST ALL OF NORTHERN LOUISIANA...AND SOUTHERN ARKANSAS AS
CONVECTION SHOULD BE MOVING INTO THESE REGIONS ON OR JUST BEFORE 6
PM THIS EVENING WITH CHANCE POPS ACROSS OUR WESTERN ZONES AS THE
PRECIPITATION WILL EXIT THIS REGION EARLY THIS EVENING. PRECIPITATION
MOVES RAPIDLY EASTWARD OVERNIGHT AND THUS...KEPT LOW END CHANCE
POPS GOING ACROSS OUR EASTERN THIRD AFTER MIDNIGHT.

MOISTURE EXITS THE REGION QUICKLY OVERNIGHT AND THE TRUE COLD
FRONT WILL NOT CATCH THE DRYLINE UNTIL THE DAYTIME HOURS ON
THURSDAY THUS ALLOWING FOR ANOTHER WARM DAY ON THURSDAY AHEAD OF
THE FRONT. STRONG PRESSURE GRADIENT BUILDS BEHIND THE FRONT FOR
THURSDAY NIGHT INTO FRIDAY RESULTING IN BREEZY CONDITIONS AS OUR
UPPER LEVEL FEATURE CUTS OFF ACROSS THE CENTRAL/SOUTHERN PLAINS.
THIS SYSTEM WILL LIKELY PLAY HAVOC WITH OUR TEMPERATURES THROUGH
THE WEEKEND INTO EARLY NEXT WEEK EVEN AS IT GETS A NUDGE EASTWARD
INTO THE TENN VALLEY BY LATE WEEKEND AS AN UPSTREAM KICKER HEADS
INTO THE SOUTHERN GREAT BASIN. FOR THE MOST PART...KEPT LOW POPS
GOING FROM THURSDAY NIGHT THROUGH FRIDAY NIGHT WITH A DRY WEEKEND
AND THEN REINTRODUCED POPS TUESDAY INTO TUESDAY NIGHT AND THIS IS
DEPENDENT ON WHETHER THE UPSTREAM KICKER CUTS OFF PER ECMWF OR
OPENS UP PER GFS. EITHER WAY...THE WEEKEND INTO EARLY NEXT WEEK
LOOKS MUCH COOLER THAN THE TEMPERATURES WE HAVE EXPERIENCED THIS
WEEK.
