   ...SYNOPSIS...
   VERY SLOW/MINOR PROGRESSION OF THE UPPER PATTERN IS FORECAST FOR
   SATURDAY /DAY 3/...THOUGH THE OVERALL WRN TROUGH/CENTRAL RIDGE/ERN
   TROUGH PATTERN WILL PERSIST.  AT THE SURFACE...A LOW IS PROGGED TO
   DEEPEN JUST OFF THE NEW ENGLAND COAST...BUT OTHERWISE HIGH PRESSURE
   SHOULD CONTINUE TO PREVAIL E OF THE MS RIVER VALLEY.  FARTHER
   W...LEE TROUGHING WILL AGAIN SERVE AS A MAIN FOCUS FOR ISOLATED
   CONVECTIVE DEVELOPMENT.
   
   ...NRN HIGH PLAINS...
   SATURDAY WILL LIKELY BE A VERY SIMILAR DAY TO FRIDAY /DAY 2/...WITH
   THE RIDGING ACROSS THE PLAINS AND RESULTING LARGE-SCALE
   SUBSIDENCE/CAPPING LARGELY HINDERING CONVECTIVE
   DEVELOPMENT/INTENSITY.  WHILE VERY ISOLATED SEVERE POTENTIAL WILL
   AGAIN EXIST ACROSS THE CENTRAL AND SRN HIGH PLAINS...SOMEWHAT
   GREATER THREAT MAY EVOLVE ACROSS THE ERN MT/WRN SD VICINITY DURING

   NEWD AROUND THE SERN PERIPHERY OF THE MAIN WRN TROUGH TOWARD THE NRN
   HIGH PLAINS.  AS THIS OCCURS...CAP WEAKENING AND ISOLATED STORM
   DEVELOPMENT APPEARS POSSIBLE NEAR THE LEE TROUGH/WITHIN UPSLOPING
   LOW-LEVEL SELYS.  WITH 35 KT SWLYS AT MID LEVELS ANTICIPATED...SHEAR
   WOULD SUPPORT UPDRAFT ORGANIZATION/ROTATION AND ATTENDANT SEVERE
   POTENTIAL.  THUS -- WILL FOCUS LOW SEVERE PROBABILITY ACROSS THE NRN
   HIGH PLAINS REGION THIS FORECAST.
