   FROM NM INTO TX.  A GRADUAL INCREASE IN A LARGE HAIL/DMGG WIND
   THREAT MAY OCCUR TOWARDS THE LATE AFTERNOON/EARLY EVENING HOURS.

   BE DELAYED UNTIL CONVECTION MOVES INTO MORE MOISTURE RICH AIRMASS
   ALONG/E OF DIFFUSE DRYLINE/LEE PRESSURE TROUGH LOCATED N-S ALONG THE
   TX/NM BORDER.  RECENTLY DEVELOPED SURFACE-BASED TSTMS NEAR GUY WILL
