   SURFACE. THIS WILL RESULT IN SUSTAINED SURFACE WIND SPEEDS FROM
   20-30 MPH. IN ADDITION...WARM TEMPERATURES AND A DRY ANTECEDENT
   AIRMASS WILL FAVOR RH VALUES FROM THE SINGLE DIGITS TO THE LOW
   TEENS.

   MODEL GUIDANCE INDICATES ISOLATED TO SCATTERED THUNDERSTORMS WILL BE
   PROBABLE OVER PORTIONS OF WRN AND CNTRL CO THIS AFTERNOON. A MIX OF
   DRY AND WET THUNDERSTORMS WILL BE POSSIBLE...WHICH WILL MAINLY BE
   DUE TO A DRY BOUNDARY LAYER BEING OFF-SET BY SLOW STORM SPEEDS. OVER
   SRN WY...AS WELL AS NERN AZ AND NWRN NM...ISOLATED STORMS MAY
   OCCUR...WITH A FEW LIKELY BEING DRY GIVEN THE PRESENCE OF DEEPLY
   MIXED BOUNDARY LAYER PROFILES DEPICTED IN MODEL FORECAST SOUNDINGS.

   N OF THE CRITICAL DELINEATION...OVER THE REMAINDER OF ERN ID AND
