   ...SYNOPSIS...
   AN UPPER LEVEL TROUGH IS FORECAST TO MOVE FROM THE CENTRAL/SRN

   CONDITIONS.
   
   ...PORTIONS OF CENTRAL AND SRN-SERN WY...

   THE AFTERNOON OVER PORTIONS OF CENTRAL AND SRN-SERN WY. IN
   ADDITION...DETERMINISTIC AND ENSEMBLE FORECAST GUIDANCE INDICATES
   THAT MINIMUM RH VALUES WILL APPROACH CRITICALLY LOW VALUES. A
   CRITICAL OUTLOOK AREA WAS CONSIDERED FOR THIS REGION...BUT LACK OF
   PROLONGED DRYNESS/DROUGHT CONDITIONS AND ONLY MARGINALLY LOW RH
   PRECLUDES ISSUANCE. HOWEVER...THE STRONG WINDS WILL LIKELY AGGRAVATE
