   ...SYNOPSIS...
   UPPER RIDGE IS FORECAST TO PERSIST BUT WEAKEN OVER THE WEST AS
   HEIGHTS FALL OVER THE NRN ROCKIES / SRN CANADA AHEAD OF SHORT-WAVE
   TROUGH AND EMBEDDED SMALLER-SCALE FEATURES MOVING SEWD FROM WRN
   CANADA.  IN THE EAST...TROUGH IS FORECAST TO PERSIST BUT WILL BEGIN
   MOVING SLOWLY NEWD AS STRONG SHORT-WAVE TROUGH NOW OVER THE MID MS
   VALLEY ROUNDS THE BASE OF THE TROUGH AND ROTATES CYCLONICALLY EWD
   AND THEN NEWD ACROSS THE GULF COAST STATES AND INTO THE MID-
   ATLANTIC REGION BY THE END OF THE PERIOD.
   
   AT THE SURFACE...COLD FRONT ASSOCIATED WITH ERN U.S. TROUGH WILL
   MOVE SLOWLY EWD ACROSS THE APPALACHIANS AND SHOULD APPROACH THE
   ATLANTIC COAST BY THE END OF THE PERIOD...WHILE SRN / E-W PORTION
   OF THE BOUNDARY BECOMES STATIONARY ACROSS THE GULF COAST STATES /
   CENTRAL TX THROUGH THE PERIOD.
   
   ...ATLANTIC AND GULF COASTAL AREAS...
   CONVECTION IS FORECAST TO INCREASE AHEAD OF SURFACE FRONT THIS
   AFTERNOON IN MOIST / DESTABILIZING AIRMASS ACROSS THIS REGION. 
   WITH MODERATELY-STRONG MID-LEVEL FLOW EXPECTED -- PARTICULARLY FROM
   AL / GA -- EXPECT STORMS TO ORGANIZE INTO PRIMARILY CLUSTERS /
   BOWING LINES WITH A THREAT FOR DAMAGING WINDS AND SOME HAIL. 
   ALTHOUGH SEVERE THREAT EXISTS ACROSS A LARGE AREA...CORRIDOR OF
   GREATEST THREAT APPEARS TO EXIST FROM GA NEWD INTO THE MID-ATLANTIC
   REGION AHEAD OF SHORT-WAVE TROUGH ROTATING THROUGH LARGER-SCALE
   FEATURE. 
   
   ...CENTRAL AND SRN HIGH PLAINS...
   WEAK UPPER FEATURES EVIDENT IN WV IMAGERY OVER THE NRN HIGH PLAINS
   WILL MOVE SWD ON ERN PERIPHERY OF UPPER HIGH.  STORMS SHOULD
   DEVELOP OVER THE HIGHER TERRAIN -- AND PERHAPS NEAR LEE TROUGH --
   BY AFTERNOON AS AIRMASS DESTABILIZES.  WITH MID-LEVEL FLOW 25 TO 35
   KT EXPECTED ACROSS THIS REGION...SUFFICIENT SHEAR FOR MULTICELL /
   WEAK SUPERCELL STORMS WILL EXIST.  LARGE HAIL AND LOCALLY DAMAGING
   WINDS WILL BE THE PRIMARY SEVERE THREATS.  STORMS SHOULD DEVELOP /
   SPREAD SEWD OVERNIGHT AS LOW-LEVEL JET INCREASES AND THEN VEERS
   WITH TIME.
   
   ...MIDWEST...
   A LOW-PROBABILITY THREAT FOR MARGINALLY-SEVERE HAIL / LOCALLY
   DAMAGING WINDS IS FORECAST ACROSS THIS REGION TODAY.  DESPITE WEAK
   SHEAR...MARGINALLY-UNSTABLE AIRMASS WILL PERSIST AS MID-LEVEL
   THERMAL TROUGH MOVES SLOWLY ACROSS THIS REGION...SUFFICIENT TO
   SUPPORT STRONG / ISOLATED SEVERE STORM DEVELOPMENT.  
   
   ...AZ...
   WEATHER PATTERN IS FORECAST TO REMAIN SIMILAR ACROSS AZ THIS PERIOD
   WITH DEEPLY-MIXED BOUNDARY LAYER DEVELOPING THIS AFTERNOON. 
   THUNDERSTORMS SHOULD AGAIN DEVELOP OVER THE HIGHER TERRAIN AND THEN
   MOVE EWD INTO LOWER ELEVATIONS -- PARTICULARLY ACROSS SERN INTO S
   CENTRAL AZ WHERE MID-LEVEL FLOW SHOULD BE A LITTLE STRONGER SOUTH
   OF PERSISTENT UPPER CYCLONE.  LOCALLY DAMAGING WINDS / HAIL WILL
   AGAIN BE POSSIBLE WITH ONE OR TWO OF THE STRONGER STORMS.2
   
   ...NERN CA / WRN NV NEWD INTO WRN MT...
   HEIGHT FALLS ARE FORECAST ACROSS THIS REGION AS UPPER ANTICYCLONE
   WEAKENS AHEAD OF SHORT-WAVE TROUGH MOVES SEWD TOWARD THE REGION. 
   GREATEST INSTABILITY IS FORECAST ACROSS PARTS OF NRN CA / SRN
   ORE...WHERE WEAK DEEP-LAYER WIND FIELD BUT DEEPLY-MIXED BOUNDARY
   LAYER SUGGESTS A THREAT FOR LOCALLY DAMAGING WINDS WITH ONE OR TWO
   OF THE STRONGER STORMS.  FURTHER NE ACROSS ID INTO WRN
   MT...INSTABILITY IS FORECAST TO BE WEAKER BUT DEEP-LAYER WIND FIELD
   STRONGER.  THIS SUGGESTS THAT A LIMITED SEVERE THREAT MAY EXTEND
   NEWD INTO THIS REGION AS WELL.
