   DISCUSSION...THUNDERSTORMS HAVE BEEN GRADUALLY INCREASING ACROSS

   THIS DEVELOPMENT MAY BE AIDED BY A WEAK IMPULSE/SUBTLE MCV VIA

   STEEPENING LOW-LEVEL LAPSE RATES/ADEQUATE CAPE MAY ALLOW FOR SOME
   SUSTAINED EASTWARD-MOVING CLUSTERS CAPABLE OF DOWNBURSTS THIS
   AFTERNOON. WHILE NOT SEVERE...SOMEWHAT STRONGER CALIBER WIND GUSTS
