   ...SYNOPSIS...
   MID/UPPER LEVEL TROUGH OVER A MAJORITY OF THE WRN U.S. WILL AMPLIFY
   DURING THE PERIOD.  MID/UPPER LEVEL LOW OVER SWRN SECTIONS OF
   ALBERTA WILL MOVE SLOWLY SEWD INTO SERN ALBERTA AS VIGOROUS
   SHORTWAVE DEVELOPS OVER WRN ORE AND MOVES SWD INTO NRN PARTS OF
   CENTRAL CA.  MEANWHILE...MID/UPPER LEVEL RIDGE WILL BE OVER THE
   MIDDLE/SRN ATLANTIC REGIONS EXTENDING NWWD OVER THE GREAT LAKES
   LEAVING WEAK TROUGHING OVER THE CENTRAL PLAINS.
   
   LARGE SURFACE RIDGE WILL EXTEND FROM NEW ENGLAND INTO THE OHIO/
   TENNESSEE VALLEYS.  COLD FRONT ASSOCIATED WITH WRN U.S. TROUGH WILL
   EXTEND FROM ERN MT INTO NRN UT EARLY IN THE PERIOD...MOVING EWD FROM
   THE ERN DAKOTAS SWWD THROUGH NERN CO INTO CENTRAL NV BY THE END OF
   THE PERIOD.
   
   ...NRN AND CENTRAL INTERMOUNTAIN REGION INTO THE NRN HIGH PLAINS...
   
   STRONG TROUGH WILL BRING DEEP LAYER SHEAR TO MUCH OF THE REGION
   BEHIND COLD FRONT AS IT MOVES EWD TOWARDS THE NRN PLAINS. MODELS
   INDICATE THAT THERE WILL BE SOME SHEAR ALONG/JUST AHEAD OF THE FRONT
   ...BUT DUE TO LIMITED LOW LEVEL MOISTURE...ONLY MARGINAL INSTABILITY
   WITH CAPE TO AROUND 500 J/KG IS ANTICIPATED.  VERY STEEP LAPSE RATES
   OF 8.0 TO 9.0 C/KM ARE ALSO EXPECTED IN THE VICINITY OF THE FRONT
   WILL ONLY ENABLE THE DEVELOPMENT OF ISOLATED...HIGH BASED TYPE
   THUNDERSTORMS. GIVEN THE NATURE OF THE ENVIRONMENT...SOME OF THESE
   STORMS HAVE A SLIGHT PROBABILITY OF PRODUCING MICROBURST WINDS
   DURING THE AFTERNOON.
   
   ...FLORIDA...
   MORE WIDESPREAD THUNDERSTORMS WILL BE EXPECTED OVER THE CENTRAL AND
   SRN FL PENINSULA WELL IN ADVANCE OF HRCN FRANCES.  COMBINATION OF
   ABUNDANT MOISTURE AND DAYTIME HEATING WILL POSE FAVORABLE UNSTABLE
   AIR MASS ACROSS THE REGION.  MODEL SOUNDINGS SHOW MODERATE ELY/NELY
   FLOW ALONG ERN COASTAL AREAS WHICH WILL FAVOR SEA BREEZE STORMS. 
   THIS IN ADDITION TO EXTREME OUTER BANDS OF FRANCES POSSIBLY
   APPROACHING THE AREA MAY LEAD TO MORE WIDESPREAD THUNDERSTORM
   ACTIVITY. STAY TUNED TO ADDITIONAL MESSAGES FROM NHC/TPC ON THE
   PROGRESS OF HRZN FRANCES.
