VALID 301647Z - 301815Z

SCATTERED THUNDERSTORMS ARE EXPECTED TO INTENSIFY SOON ALONG A BROAD
AXIS FROM NORTHERN MS INTO SOUTHWEST GA.  A SEVERE THUNDERSTORM
WATCH MAY BE ISSUED FOR THIS REGION.

VISIBLE SATELLITE IMAGERY SHOWS SCATTERED CU/TCU BEGINNING TO
DEVELOP IN A ZONE FROM NORTHERN MS...ACROSS AL...INTO SOUTHWEST AL.
FULL MORNING SUNSHINE HAS ALLOWED TEMPERATURES IN THIS REGION TO
RISE INTO THE 90S.  DEWPOINTS IN THE LOWER 70S AND CONTINUED DIURNAL
HEATING WILL YIELD MLCAPE VALUES OVER 1500 J/KG AND STEEP LOW LEVEL
LAPSE RATES.  WATER VAPOR IMAGERY SHOWS WEAK RESIDUAL FEATURES FROM
YESTERDAYS CONVECTION...BUT OVERALL LARGE SCALE FORCING IS
NEGLIGIBLE.  VERTICAL SHEAR PROFILES ARE ALSO QUITE WEAK.
HOWEVER...PW VALUES OF NEARLY 2 INCHES ON 12Z JAN/BHM SOUNDINGS AND
DEGREE OF INSTABILITY INDICATE A RISK OF SLOW MOVING INTENSE
THUNDERSTORMS WITH LOCALLY DAMAGING WINDS AND HEAVY RAINFALL.
