   ...SYNOPSIS...
   ERN U.S. TROUGH IS FORECAST TO MOVE MORE QUICKLY EWD / NEWD ACROSS
   THE ERN CONUS...WHILE UPSTREAM TROUGH IS EXPECTED TO BEGIN AFFECTING
   THE WRN U.S. THIS PERIOD.  SHORT-WAVE TROUGH -- INITIALLY EXPECTED
   OVER TX / MEXICO -- IS FORECAST TO MOVE EWD ACROSS THE GULF OF
   MEXICO THROUGH THE PERIOD.
   
   AT THE SURFACE...COLD FRONT WHICH SHOULD BE LINGERING NEAR OR JUST S
   OF THE FL PENINSULA MAY WOBBLE SLIGHTLY NWD AS SHORT-WAVE TROUGH
   CROSSES THE GULF...SUGGESTING A LIMITED POSSIBILITY FOR CONVECTION
   OVER S FL -- PARTICULARLY LATE IN THE PERIOD. 
   
   ...S FL...
   THOUGH COLD FRONT -- AND MORE FAVORABLE BOUNDARY-LAYER AIRMASS --
   SHOULD REMAIN S OF THE PENINSULA THROUGH MOST OF THE PERIOD...IT
   APPEARS ATTM THAT BOUNDARY MAY DRIFT NWD INTO S FL LATER IN THE
   PERIOD IN RESPONSE TO GULF VORT MAX.
   
   SHOULD THIS SCENARIO PAN OUT...COMBINATION OF INCREASING FLOW ALOFT
   OVER MORE MOIST / UNSTABLE BOUNDARY LAYER COULD ALLOW A FEW SEVERE
   STORMS TO DEVELOP AS FAR N AS S FL LATER IN THE PERIOD.
