   ...PORTIONS OF CNTRL/SRN NM...
   WARM TEMPERATURES IN THE 70S TO LOWER 90S ALONG WITH AN ANTECEDENT
   DRY AIR MASS...WILL LEAD TO CRITICALLY LOW RH VALUES OF 8 TO 15

   THIS AFTERNOON IN VICINITY OF A WEAK SHORTWAVE MOVING ACROSS NM INTO
   THE TX PANHANDLE. AS THE SHORTWAVE INDUCES SURFACE LOW PRESSURE
   ACROSS NWRN TX...AN INCREASE IN SURFACE WINDS ACROSS CNTRL/SRN NM
