   ...SYNOPSIS...
   LARGE SCALE BLOCKING PATTERN WILL PERSIST OVER THE CONUS FOR SEVERAL
   DAYS...INCLUDING THE DAY 3 PERIOD.  THE PRIMARY FEATURE OF INTEREST
   FOR DEEP CONVECTION WILL BE THE BROAD CLOSED LOW OVER THE MS/OH
   VALLEY AREA.  COLD MID LEVEL TEMPERATURES AND DAYTIME HEATING MAY
   SUPPORT A FEW LOW-TOPPED STORMS...POTENTIALLY WITH SMALL HAIL...BUT
   THE SEVERE THREAT WILL BE LIMITED BY RELATIVELY WEAK INSTABILITY. 
   OTHERWISE...INSTABILITY WILL BE QUITE LIMITED ACROSS THE GULF STATES
   IN THE WAKE OF A DAY 2 FRONTAL PASSAGE...WHILE LOW-LEVEL
   MOISTURE/INSTABILITY WILL ALSO BE WEAK ACROSS FL AND THE SE ATLANTIC
   STATES.  SOME ELEVATED MOISTURE RETURN WILL BE POSSIBLE ACROSS TX
   LATE IN THE PERIOD...BUT THE THUNDERSTORM THREAT SHOULD BE DELAYED
   UNTIL BEYOND DAY 3 THIS AREA.
