   CONCERNING...SEVERE THUNDERSTORM WATCH 26...
   
   VALID 012124Z - 012330Z
   
   THE THREAT FOR MAINLY LARGE HAIL EXPECTED TO CONTINUE ACROSS MUCH
   OF WW 26 NEXT FEW HOURS. THE GREATEST THREAT FOR SEVERE WEATHER
   THROUGH 23Z APPEARS TO BE OVER THE NRN FL PENINSULA. 
   
   SURFACE BOUNDARY EXTENDS FROM THE WRN ATLANTIC WWD THROUGH THE
   NRN FL PENINSULA INTO THE NRN GULF. ATMOSPHERE REMAINS MODERATELY
   UNSTABLE S OF THIS FEATURE. A RATHER BROAD SWLY 30-40 KT JET WILL
   PERSIST IN THE EXIT REGION OF AN APPROACHING MID-UPPER LEVEL
   SPEED MAX. WARM ADVECTION/LIFT IN FRONTAL ZONE ASSOCIATED WITH
   THE LOW LEVEL JET WILL MAINTAIN CONVECTIVE DEVELOPMENT INTO THE
   EVENING. GIVEN STRENGTH OF DEEP LAYER SHEAR...ISOLATED ELEVATED
   SUPERCELLS REMAIN LIKELY N OF THE FRONT. OTHER STORMS ARE
   DEVELOPING ON THE SURFACE FRONT OVER NRN FL IN PROXIMITY TO THE
   UNSTABLE LOW LEVEL INFLOW. THESE STORMS APPEAR SURFACE BASED AND
   MAY HAVE THE GREATEST POTENTIAL FOR BECOMING ORGANIZED. ISOLATED
   DAMAGING WIND AND LARGE HAIL SHOULD BE THE PRIMARY THREATS WITH
   THIS ACTIVITY.
