...SEVERE THUNDERSTORMS WILL SPREAD ACROSS NERN TX TOWARD NWRN LA...

WELL DEFINED MVC IS DROPPING SWD ALONG THE OK/AR BORDER WITHIN
REMNANTS OF EARLY MORNING CONVECTIVE DEBRIS.  THIS FEATURE REMAINS
INFLUENTIAL IN ONGOING SEVERE THUNDERSTORM EVOLUTION OVER NERN TX AS
MODEST NWLY FLOW EXTENDS FROM CNTRL OK TOWARD THE SABINE RIVER WITH
NEAR 40KT OBSERVED AT 6KM AT PAT PROFILER.  IN ADDITION...THERE
APPEARS TO BE SOME ISENTROPIC ASCENT AIDING THIS ACTIVITY AS LATEST
SFC DIAGNOSTIC DATA SUGGESTS WARM FRONT STRETCHES FROM CNTRL LA NWWD
INTO SUPERCELL CLUSTERS WEST OF TXK.  LATEST THINKING IS THIS
DEVELOPING MCS WILL CONTINUE DRIVING SWD AT 30KT...WITH THE
POTENTIAL FOR INCREASING FORWARD PROPAGATION DURING THE EVENING AS
COLD POOL EVOLVES.  DAMAGING WIND THREAT APPEARS TO BE INCREASING.
