   LARGE UPPER LOW THAT HAS BEEN OFF THE CA COAST FOR THE LAST COUPLE
   OF DAYS WILL BEGIN SHIFTING EASTWARD TODAY...WITH MAIN SHORTWAVE
   TROUGH ROTATING ACROSS THE SOUTHWEST STATES.  SCATTERED
   SHOWERS/THUNDERSTORMS WILL BE POSSIBLE FROM MUCH OF CA INTO THE FOUR
   CORNERS REGION...AS WELL AS FAR WEST TX.  TWO SMALL AREAS WITHIN
   THIS REGION APPEAR TO HAVE A SLIGHTLY HEIGHTENED THREAT OF STRONG
   CONVECTION TODAY.
   
   ...SOUTHERN CA COAST THIS MORNING...
   PRIMARY UPPER VORT MAX IS APPROACHING THE LA BASIN AT THIS TIME. 
   SCATTERED THUNDERSTORMS HAVE BEEN OCCURRING ALONG THE COAST FOR THE
   LAST FEW HOURS...WITH ISOLATED CELLS SHOWING SOME POTENTIAL FOR
   HAIL.  THIS THREAT WILL PERSIST THROUGH MID MORNING AS NEW CELLS
   GENERATE JUST OFFSHORE AND MOVE INLAND.  ACTIVITY SHOULD DIMINISH BY
   THIS AFTERNOON AS UPPER SYSTEM MOVES EASTWARD.
   
   ...SOUTHWEST AZ THIS AFTERNOON...
   PRESENT INDICATIONS ARE THAT PRIMARY UPPER SYSTEM WILL MOVE INTO
   WESTERN AZ BY THIS AFTERNOON.  AXIS OF HIGHER LOW LEVEL MOISTURE
   VALUES IS PRESENT IN THIS REGION...WITH DEWPOINTS IN THE LOW/MID
   50S.  COMBINATION OF DAYTIME HEATING...COOLING ALOFT...AND
   INCREASING UPPER FORCING FOR VERTICAL MOTION WILL AID IN THE
   DEVELOPMENT OF SCATTERED AFTERNOON THUNDERSTORMS.  A FEW STORMS
   COULD PRODUCE GUSTY WINDS OR HAIL.  ORGANIZED SEVERE STORMS ARE NOT
   ANTICIPATED AT THIS TIME.
