   ...SYNOPSIS...
   MID-LEVEL PATTERN IS FORECAST TO AMPLIFY THIS PERIOD AS SHORT-WAVE
   TROUGH EXITS THE ERN SEABOARD. BEHIND THIS TROUGH...AMPLIFICATION
   OF LARGE-SCALE RIDGE IS FORECAST ACROSS THE CENTRAL AND ERN CONUS
   DOWNSTREAM OF STRONG / DIGGING WRN U.S. TROUGH.  BY THE END OF THE
   PERIOD...SHARP WRN TROUGH IS FORECAST TO EXTEND FROM WRN CANADA SWD
   ACROSS THE GREAT BASIN / CA INTO THE ERN PACIFIC W OF BAJA
   CA...WHILE A RIDGE EXTENDS FROM THE GULF OF MEXICO NWD TO THE GREAT
   LAKES.
   
   ...TN VALLEY REGION...
   A LOW-PROBABILITY SEVERE THREAT WILL BE MAINTAINED THIS FORECAST
   PERIOD ACROSS PARTS OF WRN AND MIDDLE TN INTO ADJACENT WRN
   KY...THOUGH CONFIDENCE REMAINS LOW.
   
   DAYTIME HEATING OF MOIST BOUNDARY LAYER SHOULD CONTRIBUTE TO CU
   DEVELOPMENT ACROSS THE SOUTHEAST...BUT VERTICAL GROWTH SHOULD REMAIN
   SUPPRESSED THOUGH MUCH OF THE DAY DUE TO LARGE-SCALE SUBSIDENCE /
   WARMING AT MID-LEVELS AS RIDGING OVERSPREADS THIS REGION BEHIND
   DEPARTING SHORT-WAVE TROUGH.  SUBSIDENCE AND ASSOCIATED WEAK SURFACE
   PATTERN / LIMITED BOUNDARY-LAYER CONVERGENCE SUGGESTS ONLY A LIMITED
   THREAT FOR DEEPER CONVECTION.  ADDITIONALLY...EVEN IF CONVECTION
   GROWS SUFFICIENT DEEP LOCALLY TO ALLOW ISOLATED STORM
   DEVELOPMENT...RELATIVELY WEAK DEEP-LAYER WIND FIELD WITHIN MID-LEVEL
   SHORT-WAVE RIDGE SUGGESTS ONLY A MINIMAL SEVERE THREAT AT BEST.
