Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

What forecasters said that day

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.

NWS Shreveport, LA wrote its last area forecast discussion before this tornado warning went out at Apr 12, 10:07 AM CDT, 1 hour 40 minutes earlier.

Area forecast discussion, Apr 12, 10:07 AM CDT, 1 hour 40 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SHREVEPORT LA
1007 AM CDT SUN APR 12 2009

.DISCUSSION...
ZONE UPDATE JUST SENT TO ADD SVR WATCH #144 FOR EXTREME ERN TX/N
LA/SW AR THROUGH 21Z. MOSTLY ELEVATED LINE OF CONVECTION CONTINUES
TO ADVANCE QUICKLY EAST ACROSS E TX ATTM...WITH OTHER ISOLATED
STORMS DEVELOPING AHEAD OF THE LINE OVER SCNTRL AR/NCNTRL LA.
GIVEN LOW WET BULB ZERO HEIGHTS OVER SW AR...HAIL WILL BE OF THE
MAIN CONCERN WITH THESE STORMS...ALTHOUGH LINE ITSELF OVER E TX
HAS BEEN CONSISTENTLY PRODUCING WIND GUSTS TO 40-45 MPH. SFC
ANALYSIS INDICATES A DEVELOPING SFC LOW BETWEEN UTS AND LFK...WITH
ATTENDANT WARM FRONT/WARM NOSE EXTENDING ACROSS THE NRN REACHES OF
SE TX...TO LOWER TOLEDO BEND RESERVOIR...INTO SCNTRL LA. WARM NOSE
HAS PENETRATED INTO ANGELINA COUNTY ATTM...BUT CURRENT EWD MOVING
CONVECTION MAY SUPPRESS THE NWD MOVEMENT OF THE FRONT INTO E TX.

STRONG SFC CONVERGENCE/UPPER LEVEL DIFFLUENCE WILL MAINTAIN THE
LINE AS IT SURGES E ACROSS SW AR/N LA THIS AFTERNOON. THE TORNADO
THREAT WILL BE DETERMINED WITH THE NWD EXTENT OF THE WARM FRONT
OVER CNTRL LA LATER TODAY...BUT STRONG 0-1KM SHEAR OF 35-40+ KTS
AND STRONG BACKING OF THE LOW LEVEL FLOW WILL ENHANCE THE TORNADO
THREAT SHOULD THE BOUNDARY REACH NCNTRL LA LATER TODAY.

NO UPDATES NEEDED TO THE CURRENT FORECAST...OTHER THAN TO ADD
WATCH WORDING. DRY SLOTTING WILL INCREASE FROM THE W LATER
TODAY...ALTHOUGH A MARGINAL SVR HAIL THREAT WILL EXIST GIVEN THE
PROXIMATELY OF THE COLD CORE LOW.

.AVIATION...

POOR FLIGHT CONDITIONS WILL PERSIST AREAWIDE THROUGH MUCH OF THE
DAY...AS LOW MVFR CIGS ATTRIBUTED TO WIDESPREAD STRONG TO SVR
CONVECTION CONTINUES TO SHIFT E ACROSS THE REGION. CONVECTION WILL
DIMINISH FROM W TO E THIS AFTERNOON...ALTHOUGH ISOLATED CONVECTION
WILL REMAIN POSSIBLE OVERNIGHT NW OF I-30 OF NE TX/SW AR/SE
OK...NEAR THE CLOD CORE LOW. /15/
