AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHEYENNE WY
255 AM MDT WED AUG 23 2006

.SHORT TERM...CRITICAL FIRE WEATHER CONDITIONS WILL BE OVER THE
CWA THIS AFTERNOON AND EARLY EVENING AND POSSIBLY AGAIN THURSDAY
AFTERNOON AND EVENING.  THE FLOW ALOFT INCREASES AND BECOMES MORE
WESTERLY TODAY IN RESPONSE TO THE APPROACH OF A SHORT WAVE TROUGH
CURRENTLY NEARING THE PACIFIC NORRTHWEST COAST.  ALREADY THE
MEDICINE BOW PROFILER HAS 25 KNOTS OF WIND IN ITS LOWEST GATE.
SURFACE PRESSURE GRADIENT ON THE MODELS TODAY IS NOT VERY TIGHT
AND SO THE WINDS WILL BE DUE TO DEEP MIXING OF THE ATMOSPHERE
BRIGNING DOWN UP TO 35 KNOTS OF WIND FROM 500 MB.  THE SHORTWAVE
TROUGH AND ASSOCIATED PACIFIC COLD FRONT MOVE ACROSS THE NORTHERN
AND CENTRAL ROCKIES ON THURSDAY AND WESTERLY WINDS WILL BE EVEN
STRONGER.  BETTER MID AND UPPER LEVEL MOISTURE PLUME WILL BE TO
THE SOUTH OF THE CWA THROUGH THURSDAY AND THE ATMOSPHERE WILL BE
DRY.  WILL KEEP AFTERNOON AND EVENING HIGH BASED THUNDERSTORM
ACTIVITY CENTERED OVER THE MOUNTAINS TODAY AND THEN SHIFT ANY THREAT
OF SHOWERS AND STORMS TO THE FAR SOUTH ON THURSDAY AFTERNOON. DRIER
AIR ON THE WEST WINDS SPREAD ACROSS THE CWA BEHIND THE FRONT AND
SHORTWAVE TROUGH FOR THURSDAY.  THE TEMPERATURES WILL BE VERY WARM
TODAY AND THEN COOL 4 TO 8 DEGREES FOR THURSDAY.

.LONG TERM...THURSDAY NIGHT THROUGH WEDNESDAY...FAIRLY QUIET WX
EXPECTED FOR THE PERIOD AS DRIER AIR REMAINS OVER THE CWA. NEXT
UPPER SYSTEM WILL MOVE THRU THE NRN RKYS FRIDAY AND INTO THE NRN
PLAINS EARLY SATURDAY.  THIS SHOULD SET OFF WIDELY SCTD CONVECTION
MAINLY FRIDAY EVENING AS LOBE OF VORT PASSES BY.  GFS HANGS SOME
ENERGY BACK OVER THE WRN CONUS DURING THE WEEKEND WHILE NAM REBUILDS
UPPER RIDGING.  GFS AN OUTLIER AS MOST OTHER MODELS CLOSER TO THE
NAM SO WILL FAVOR SYSTEM BASICALLY MOVING BY WITH RIDGING RETURNING
ON ITS HEELS.  UPPER RIDGE ALSO KEEPS MOISTURE SUPPRESSED WELL SOUTH
OF THE CWA INTO EARLY NEXT WEEK THOUGH SOME MAY TRY TO CREEP BACK BY
MIDWEEK.

&&

.FIRE WEATHER...THIS AFTERNOON AND EARLY EVENING ARE SHAPING UP TO
BE A CRITICAL FIRE WEATHER PERIOD.  ALTHOUGH WIND SPEEDS DO NOT
SEEM AS STRONG DURING THAT TIME AS THEY DID A DAY OR TWO AGO...
DEEP MIXING SHOULD ALLOW FOR 35 KNOT WINDS TO MAKE IT TO THE SURFACE
IN MOST PLACES.  OTHERWISE HIGH TEMPERATURES WILL BE FROM 85 TO
102 IN THE LOWER ELEVATIONS AND RELATIVE HUMIDITIES FROM 10 TO 16
PERCENT.  TO ADD TO THE MIX...SOME HIGH BASED...DRY THUNDERSTORMS
WILL FORM THIS AFTERNOON OVER AND THE NEAR THE MOUNTAINS.  HAVE
UPGRADED THE FIRE WEATHER WATCH FOR THE CWA TO A RED FLAG WARNING.
WILL HAVE TO CONSIDER ANOTHER HIGHLIGHT FOR THURSDAY AFTERNOON AND
EARLY EVENING.  TEMPERATURES WILL BE A BIT COOLER...BUT WIND
SPEEDS WILL BE EVEN STRONGER ON THURSDAY NEAR AND BEHIND A COLD
FRONT.
