AREAS AFFECTED...FAR ERN TX INTO WRN AND CNTRL LA

CONCERNING...TORNADO WATCH 167...

VALID 080355Z - 080530Z

THROUGH 06Z...POTENTIAL FOR MAINLY DAMAGING WINDS WILL EXIST ACROSS
CNTRL AND SRN PORTIONS OF WW AREA.

A STRONGLY FORCED CONVECTIVE LINE HAS RAPIDLY EVOLVED OVER THE PAST
HALF HOUR ALONG COLD FRONT FROM S-CNTRL AR SWWD INTO SERN TX /SE OF
LFK/.  CURRENT SURFACE OBSERVATIONS INDICATE THAT PRE-FRONTAL AIR
MASS ACROSS LA REMAINS QUITE MOIST WITH DEWPOINTS IN THE MID TO
UPPER 60S.  MOREOVER...WINNFIELD LA PROFILER SHOWS THAT AMBIENT
KINEMATIC ENVIRONMENT IS STRONGLY SHEARED WITH 50-60 KTS OF
DEEP-LAYER SHEAR AND 0-1 KM SRH OF 200-300 M2/S2.

GIVEN THE PROMINENT LINEAR CONVECTIVE MODE ALONG FRONT...IT APPEARS
THAT DAMAGING WINDS WILL BE THE PRIMARY SEVERE WEATHER THREAT AS
STORMS CONTINUE SEWD AT 30-35 KTS.  HOWEVER...THE STRONG LOW-LEVEL
SHEAR DOES SUGGEST SOME POTENTIAL FOR EMBEDDED SUPERCELLS OR LEWP
STRUCTURES CAPABLE OF AN ISOLATED TORNADO.
