...DISCUSSION...

BOTH THE GFS AND ECMWF ARE IN REASONABLE AGREEMENT REGARDING THE
EVOLUTION OF A SWD-MOVING UPPER LOW INTO TX EARLY NEXT WEEK. WHILE
THIS FEATURE IS EXPECTED TO INCREASE SHEAR ACROSS THE COASTAL PLAINS
OF TX/LA...WEAK LOW LEVEL CONVERGENCE ALONG A SAGGING FRONTAL ZONE
AND WEAK-MODEST INSTABILITY DO NOT PARTICULARLY FAVOR ORGANIZED
SEVERE THUNDERSTORMS.
