   DAY 3 CONVECTIVE OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0159 AM CDT SAT AUG 27 2011
   
   VALID 291200Z - 301200Z
   
   ...SYNOPSIS...
   
   THE PRIMARY FOCUS FOR CONVECTION DURING THE DAY3 PERIOD WILL REMAIN
   ACROSS THE ROCKIES AND OVER THE FL PENINSULA.  IN BOTH OF THESE
   AREAS ANY STORMS THAT DEVELOP WILL DO SO WITHIN A FAIRLY BENIGN
   ENVIRONMENT...SHEAR WISE.  STRONG HEATING ACROSS THE HIGHER TERRAIN
   OF THE WRN U.S. WILL ONCE AGAIN CONTRIBUTE TO ADEQUATE
   DESTABILIZATION FOR AFTERNOON/EVENING THUNDERSTORMS WHILE WEAK WARM
   ADVECTION DOWNSTREAM ACROSS THE PLAINS MAY ALSO CONTRIBUTE TO
   EPISODIC BOUTS OF ELEVATED CONVECTION.
   
   WEAK DEEP LAYER WLY FLOW ACROSS THE ERN GULF BASIN/FL PENINSULA
   SHOULD ENCOURAGE AN EAST COAST SEA BREEZE THAT WILL FOCUS
   THUNDERSTORM ACTIVITY ACROSS THIS REGION BY 18-21Z.  DIURNAL COOLING
   WILL PROVE DETRIMENTAL TO THIS ACTIVITY AND STORMS SHOULD MIGRATE
   OFFSHORE BY EARLY EVENING.
