   LINE OF THUNDERSTORMS ACROSS EXTREME SERN LA AND SERN MS
   CONTINUES TO INTENSIFY.  DAMAGING WINDS AND AN ISOLATED TORNADO
   APPEAR POSSIBLE ACROSS THIS AREA. HOWEVER...UNLESS THREAT
   INCREASES DRAMATICALLY...NEW WW WILL LIKELY NOT BE ISSUED AS AREA
   NOT INCLUDED IN WW'S 7 AND 8 IS LIMITED.
   
   LATEST SURFACE AND OBJECTIVE ANALYSES SHOW MOIST / MARGINALLY
   UNSTABLE AIRMASS ACROSS THE GULF COAST / LOWER MS VALLEY REGION
   ATTM.  WITH INCREASINGLY FAVORABLE LOW-LEVEL VEERING AND
   DEEP-LAYER SHEAR INDICATED BY MOB WSR-88D...SEVERE THREAT APPEARS
   TO BE INCREASING.  SEVERE THREAT ACROSS THIS REGION MAY BE
   FURTHER ENHANCED BY INCREASING LARGE-SCALE UVV AHEAD OF
   APPROACHING MID-LEVEL VORT MAX / JET STREAK AND APPROACH OF UPPER
   60F SURFACE DEW POINTS.  LIMITED AREAL COVERAGE SUGGESTS WW NOT
   NECESSARY ATTM...THOUGH AREA MAY NEED TO BE INCLUDED IN ANY
   FURTHER WW/S LATER THIS EVENING.
