AREAS AFFECTED...FAR SERN TX/SWRN AND CENTRAL LA

CONCERNING...TORNADO WATCH 101...

VALID 201236Z - 201330Z

TORNADO THREAT REMAINS ACROSS VALID PART OF WW 101 EXTENDING FROM
FAR SERN TX INTO SWRN/CENTRAL LA.

12Z SURFACE ANALYSIS SHOWED A WARM FRONT EXTENDING FROM THE UPPER TX
COASTAL PLAINS /35 NW HOU/ NEWD TO 10 S POE TO 15 S HEZ...AND THEN
SEWD ACROSS SERN MS TO FAR SWRN AL.  MEANWHILE...OUTFLOW BOUNDARY...
ASSOCIATED WITH EXTENSIVE AREA OF CONVECTION OVER NERN TX/NRN LA TO
PARTS OF NRN MS...WAS PARALLEL AND JUST NORTH OF THE WARM FRONT IN
SE TX/WRN LA...AND THEN EXTENDED NEWD INTO NRN MS.

REGIONAL RADARS INDICATED THE STRONGEST STORM WITHIN WW 101 WAS
LOCATED IN NEWTON COUNTY AT 1230Z TRACKING TOWARD THE ENE.  THIS
STORM HAS MAINTAINED A PERSISTENT LOW-LEVEL ROTATION FOR THE LAST 2
HOURS. CLOSE PROXIMITY OF THIS STORM TO THE WARM FRONT AND OUTFLOW
BOUNDARY WOULD SUGGEST A HEIGHTENED TORNADO THREAT...GIVEN ENHANCED
LOW-LEVEL SHEAR VALUES ALONG THESE BOUNDARIES.

FARTHER S ALONG THE UPPER TX COAST REGION...RECENT THUNDERSTORM
DEVELOPMENT APPEARS TO BE WITHIN LOW-LEVEL WAA REGIME WITH ISOLATED
HAIL BEING THE PRIMARY THREAT WITH THIS ACTIVITY.
