AREAS AFFECTED...SWRN WY / ERN UT / WRN CO

CONCERNING...SEVERE THUNDERSTORM WATCH 151...

VALID 052241Z - 052345Z

POTENTIAL FOR LOCALLY STRONG WIND GUSTS WILL LIKELY CONTINUE BEYOND
23Z...HOWEVER AN ADDITIONAL WW IS NOT ANTICIPATED ATTM.

CLUSTERS OF TSTMS ARE ONGOING AS OF 2225Z FROM N-CNTRL NM NWD
THROUGH PORTIONS OF WRN AND CNTRL CO INTO WRN AND CNTRL WY WITHIN
ZONE OF STRONG LARGE-SCALE FORCING FOR ASCENT ASSOCIATED WITH UPPER
LOW EVOLVING OVER THE GREAT BASIN.  REGIONAL VWPS INDICATE LARGELY
UNIDIRECTIONAL WIND PROFILES WITH RELATIVELY STRONG VERTICAL SPEED
SHEAR...SUPPORTIVE OF ORGANIZED SEVERE TSTMS.  HOWEVER...VISIBLE
SATELLITE AND SURFACE OBSERVATIONS INDICATE THAT CONSIDERABLE CLOUDS
AND PRECIPITATION HAVE RESULTED IN COOLING OF PRE-FRONTAL
BOUNDARY-LAYER ACROSS WRN INTO CNTRL CO WHICH IS EFFECTIVELY
LIMITING THE DEGREE OF INSTABILITY.

THROUGH 23-01Z...IT APPEARS THE GREATEST THREAT OF LOCALLY STRONG
WIND GUSTS AND/OR MARGINALLY SEVERE HAIL WILL EXIST ACROSS NRN
PORTIONS OF WW AREA INTO N-CNTRL WY/S-CNTRL AND SERN MT WHERE
INTENSIFYING LARGE-SCALE FORCING WILL BECOME CO-LOCATED WITH A ZONE
OF WEAK TO MODERATE INSTABILITY.  ELSEWHERE...AN ISOLATED SEVERE
WEATHER THREAT MAY EXIST BEYOND 23Z...HOWEVER IT APPEARS THAT THE
TEMPORAL DURATION OF THIS THREAT WILL BE TOO LIMITED TO WARRANT THE
ISSUANCE OF AN ADDITIONAL WW.
