   COUPLE OF HOURS.  MONSOONAL MOISTURE HAS BEEN FLOWING INTO THE AREA
   WITH DEWPOINTS RAPIDLY INCREASING INTO THE 60S F AT LAS...AND MID
   50S TO LOW 60S NOTED IN NW AZ. MLCAPE VALUES IN THE REGION ARE
   APPROACHING 1000 J/KG AND STORMS THAT INITIATE ALONG TERRAIN
   FEATURES WILL BECOME STRONG IN THIS ENVIRONMENT.  GIVEN LARGE
   SURFACE TEMPERATURE/DEWPOINT SPREADS...A FEW OF THE STRONGER STORMS

   AS INDICATED ON 18Z FGZ SOUNDING SUGGEST A MARGINAL SEVERE HAIL
