AREAS AFFECTED...PORTIONS OF CENTRAL/SERN CO INTO ERN CO

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 082223Z - 090000Z

ISOLATED DAMAGING WINDS REMAIN LIKELY WITH THUNDERSTORMS SPREADING
NNEWD INTO CENTRAL/SERN WY AND ERN CO...IN LEE OF THE ROCKIES. IN
ADDITION...HIGH BASED AND MAINLY DRY THUNDERSTORMS WILL INCREASE THE
FIRE WEATHER THREAT ACROSS THIS REGION GIVEN DRY 10 HOUR FUELS AND
THE EXPECTED STRONG WIND GUSTS.

STRONG UPWARD VERTICAL MOTION ASSOCIATED WITH A VIGOROUS SHORT WAVE
TROUGH MOVING NEWD ACROSS THE CENTRAL ROCKIES COMBINED WITH STEEP
LAPSE RATES AND MID LEVEL MOISTURE WILL CONTINUE TO SUPPORT
THUNDERSTORMS AS THIS TROUGH MOVES NEWD.  A DEEP MIXED BOUNDARY
LAYER WILL RESULT IN FURTHER HIGH BASED STORMS...WITH DRY ADIABATIC
LOW-LEVEL LAPSE RATES AND 30-40 DEGREE SURFACE DEWPOINT DEPRESSIONS
SUPPORTING STRONG...DAMAGING WIND GUSTS.  MINIMAL INSTABILITY WILL
LIMIT THE COVERAGE OF SEVERE RELATED STORMS.  HOWEVER...SURFACE
PRESSURE FALL/RISE COUPLET OVER ERN UT/SRN WY INTO CO WILL ENHANCE
THE WIND SPEEDS GIVEN A STRONG ISALLOBARIC WIND COMPONENT.
