   AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
   THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
   AND POSSIBLE WARNINGS. SEVERE THUNDERSTORMS CAN AND OCCASIONALLY

   DISCUSSION...STORMS ARE EXPECTED TO CONTINUE DEVELOPING AND

   BOUNDARY LAYER WILL RESULT IN STORMS BECOMING SURFACE-BASED WITH AN
   INCREASING THREAT FOR SEVERE STORMS.  VAD PROFILES SHOW STRONG WINDS
   ABOVE THE GROUND IN THE LOWEST 2-3 KM WHICH WILL ENHANCE WIND DAMAGE
   POTENTIAL...AND STEEP LAPSE RATES WILL ALSO PROMOTE LARGE HAIL WITH
