   LOW AMPLITUDE UPPER TROUGH EMBEDDED WITHIN SOUTHERN BRANCH OF THE
   WESTERLIES WILL CONTINUE EAST NORTHEASTWARD OUT OF THE SOUTHERN
   ROCKIES TONIGHT.  STRONGER MID-LEVEL HEIGHT FALLS ARE PROGGED TO
   SHIFT ACROSS EAST TEXAS INTO THE LOWER MISSISSIPPI VALLEY...
   PRECEDED BY ZONE OF ENHANCED LOW/MID-LEVEL WARM ADVECTION...WHICH
   IS SUPPORTING ONGOING CONVECTIVE DEVELOPMENT OVER LOUISIANA/
   MISSISSIPPI. 
   
   27/00Z SOUNDINGS SUPPORT MODEL PROGS INDICATING ACTIVITY IS BASED
   IN THE 850-700 MB LAYER...ABOVE SHARP NEAR SURFACE INVERSION LAYER.
   WITH CAPE GENERALLY LESS THAN 500 J/KG...AND RELATIVE HIGH OR
   RISING WET-BULB ZERO LEVELS...POTENTIAL FOR HAIL EXCEEDING SEVERE
   LIMITS APPEARS RATHER LOW AS CONVECTION DEVELOPS EASTWARD ACROSS
   THE REMAINDER OF THE EASTERN GULF/SOUTH ATLANTIC COAST STATES
   OVERNIGHT.
   
   BENEATH INTENSIFYING MID/UPPER JET...A 50+ KT WEST SOUTHWESTERLY
   LOW-LEVEL JET IS PROGGED TO DEVELOP ALONG THE EASTERN GULF COAST...
   FROM EXTREME SOUTHEAST LOUISIANA INTO THE WESTERN FLORIDA
   PANHANDLE.  THIS WILL CONTRIBUTE TO STRONG VERTICAL SHEAR PROFILES
   AND AT LEAST A MINIMAL THREAT FOR SEVERE THUNDERSTORMS NEAR COASTAL
   AREAS...WHERE HODOGRAPHS WILL BE SUFFICIENT FOR SUPERCELLS...BUT
   CONSIDERABLY UNCERTAINTY REMAINS WITH REGARD TO DESTABILIZATION OF
   BOUNDARY LAYER.  MODELS SUGGEST WEAK SOUTHEAST LOUISIANA SURFACE
   LOW WILL MIGRATE INTO AREAS NEAR/NORTH OF MOBILE BAY...ACCOMPANIED
   BY INLAND PROGRESSION OF COASTAL FRONT ACROSS THE WESTERN FLORIDA
   PANHANDLE.  AS SURFACE DEW POINTS CLIMB INTO THE MID/UPPER 60S AND
   LOW-LEVEL SHEAR BECOMES MAXIMIZED BENEATH CORE OF LOW-LEVEL
   JET...AN ISOLATED SEVERE STORM APPEARS POSSIBLE AFTER 27/06Z...WITH
   POTENTIAL FOR DAMAGING WINDS GUSTS...PERHAPS A TORNADO.
   
   ...SOUTHWESTERN U.S...
   MID-LEVEL COLD POOL...ASSOCIATED WITH UPPER TROUGH NOW EXITING THE
   SOUTHERN ROCKIES...IS STILL CONTRIBUTING TO SUFFICIENT INSTABILITY
   FOR SCATTERED THUNDERSTORM ACTIVITY ACROSS THE SOUTHERN PLATEAU AND
   SOUTHERN ROCKIES.  THIS ACTIVITY LIKELY WILL DIMINISH AS THE
   EVENING PROGRESSES...BUT FORCING ASSOCIATED WITH NEXT JET STREAK
   DIGGING INTO THE LOWER COLORADO VALLEY IS EXPECTED TO SUPPORT
   ADDITIONAL THUNDERSTORMS ACROSS PARTS OF NORTHERN ARIZONA/SOUTHERN
   NEVADA/SOUTHERN UTAH OVERNIGHT.
