ANOTHER COOL DAY IN STORE...  LGT PCP WILL LIKELY CONT THIS MORNING THEN
INCREASE THIS AFTERNOON AS UPPER SYSTEM APPROACHES.  POPS WILL NOT BE
HIGH HOWEVER...DUE TO THE SPOTTY NATURE OF PRECIP. SOUTHERN ZONES ARE IN
SLGT RISK AREA AND THIS SEEMS REASONABLE.  BREAKS IN CLOUDS SHOULD ALLOW
SOME HEATING TODAY AND MID LEVEL LAPSE RATES PROGGED TO APPROACH 20
DEGREES.  THINK HAIL WILL BE THE MAIN THREAT DUE TO COLD NATURE OF
AIRMASS AND WIND SHEAR PROFILES. SFC WINDS WILL SLACKEN TODAY AS SFC LOW
MOVES OVER WRN ZONES. MOS SEEMS TO REFLECT CLOUDS AND COOL AIRMASS SO
WILL NOT STRAY TOO FAR FROM MOS TEMPS.
