AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
328 AM MST MON NOV 12 2007

.SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT
SHOWER ACTIVITY QUICKLY DISSIPATED LAST EVENING...WITH CLEARING
SKIES FOUND ACROSS THE AREA THIS MORNING. WITH THE SYSTEM MOVING
OUT OF THE AREA...AND SUDDENLY CLEARING SKIES...ADDED PATCHY FOG
WORDING THE JACKSON VALLEY...ALONG WITH FAVORED AREAS IN
YELLOWSTONE. LEFT SOME SLIGHT CHANCE WORDING IN FOR SOUTHERN
SWEETWATER COUNTY THROUGH 18Z TODAY...WITH DRY CONDITIONS EXPECTED
ELSEWHERE. A BRIEF PERIOD OF DRYING WILL BE FOUND DURING THE
AFTERNOON HOURS...AHEAD OF THE NEXT APPROACHING SYSTEM.
TEMPERATURES TODAY NOT EXPECTED TO BE QUITE AS COOL AS PREVIOUSLY
ANTICIPATED...THOUGH WILL STILL BE SLIGHTLY COOLER THAN YESTERDAY.
NEXT SYSTEM TO APPROACH WESTERN WYOMING DURING THE EVENING HOURS.
THIS SYSTEM WILL NOT ONLY BRING SOME ISOLATED SHOWER ACTIVITY
ACROSS THE NORTHWESTERN MOUNTAINS...BUT WILL ALSO INTRODUCE THE
FORECAST CHALLENGE FOR THE PERIOD...A STRONG PRESSURE GRADIENT
WHICH WILL CAUSE GUSTY SOUTHWEST WINDS ACROSS MUCH OF THE AREA...
AND MAY CAUSE HIGH WINDS TO DEVELOP OVER FAVORED AREAS.

THE ABSAROKA MOUNTAINS WILL BE THE FIRST TO SEE THE IMPACT OF THIS
INCREASED GRADIENT FLOW...WITH WINDS OF 50 MPH POSSIBLE DURING THE
LATE EVENING HOURS. WINDS WILL TRANSFER DOWN TO THE CODY FOOTHILLS
AFTER MIDNIGHT...WITH WINDS OF 40 MPH GUSTING TO 60 POSSIBLE. IT
SHOULD BE MENTIONED THAT A MOUNTAIN WAVE IS POSSIBLE AROUND THE AREA
OF CLARK...WITH A CURRENT FREUD NUMBER OF JUST OVER 1 CALCULATED. A
MOUNTAINTOP INVERSION WAS NOTED IN THE MODELS...HOWEVER THIS SCENARIO
WILL NEED TO CONTINUE TO BE EVALUATED. HIGHER WINDS ALSO LOOK
POSSIBLE ACROSS THE EASTERN SLOPES OF THE BIGHORN...AND WIND RIVER
MOUNTAINS ALSO AFTER MIDNIGHT. A HIGH WIND WATCH HAS BEEN ISSUED FOR
THE AFOREMENTIONED AREAS DUE TO THIS POTENTIAL...WITH POTENTIALLY
HIGH WINDS EXPECTED TO CONTINUE THROUGH TUESDAY EVENING. AS THE
PRESSURE GRADIENT MOVES SOUTHEASTWARD...IT MAY ALSO CAUSE HIGH WINDS
TO DEVELOP ACROSS THE GREEN MOUNTAINS AND RATTLESNAKE RANGE DURING
THE EARLY MORNING HOURS OF TUESDAY...AND FURTHER SPREAD INTO NATRONA
COUNTY AFTER 5 AM MST. SUSTAINED WINDS OF AROUND 40 MPH ARE POSSIBLE
ACROSS IMPACTED AREAS...WHICH INITIATED THE ISSUANCE OF A HIGH WIND
WATCH FOR THESE AREAS AS WELL. THE PRESSURE GRADIENT IS EXPECTED TO
RELAX TUESDAY EVENING...WITH THE WATCH ENDING AROUND 5PM MST.

MEANWHILE...SHOWER ACTIVITY WILL BECOME MORE DOMINANT OVER THE
WESTERN MOUNTAINS AND VALLEYS AFTER MIDNIGHT...WITH SNOW EXPECTED
AFTER 5 AM FOR THE WESTERN VALLEYS AND MOUNTAINS...ALONG WITH A
SLIGHT CHANCE FOR SNOW OVER THE BIG HORN MOUNTAINS. TEMPERATURES
EXPECTED TO WARM DURING THE DAY ON TUESDAY. SNOW SHOWERS WILL
CONTINUE ACROSS THE WEST AND BIGHORN MOUNTAINS THROUGH THE REMAINDER
OF THE FORECAST PERIOD...AND ADDED CLOUD COVER ON WEDNESDAY WILL
CAUSE TEMPERATURES TO DIP.

.LONG TERM...THURSDAY THROUGH MONDAY
EXTENDED PERIOD HAS THE POTENTIAL TO BE AN ACTIVE ONE IF THE
MEDIUM RANGE MODELS ARE CORRECT. FLAT RIDGE IS EXPECTED OVER THE
AREA INTO THE WEEKEND WITH A SERIES OF EMBEDDED SHORTWAVES
CREATING THE SETUP FOR MOIST ISENTROPIC UPGLIDE ACROSS THE WEST.
FLOW COULD BECOME EVEN STRONG AT THE BEGINNING OF NEXT WEEK WITH
STRONG OROGRAPHICS AND POTENTIAL STRONGER SHORTWAVE IMPACTING THE
WEST. THIS PATTERN WOULD ALSO PRODUCE WINDY CONDITIONS AT TIMES IN
THE MOUNTAINS...FOOTHILLS AND WIND CORRIDOR FROM NEAR RKS TO CPR.
MOST OF THE PERIOD HAS CHANCE POPS IN THE WESTERN MOUNTAINS. THE
BEGINNING OF THE PERIOD ACTUALLY LOOKS THE DRIEST AS THE AREA
LOOKS TO BE IN BETWEEN SYSTEMS. HAVE TRIMMED BACK POPS TO JUST
SLIGHT CHANCES IN THE WESTERN MOUNTAINS FOR THURSDAY. NO
SIGNIFICANT COLD AIR IS EXPECTED TO AFFECT THE AREA UNTIL PERHAPS
THE END OF THIS PERIOD OR JUST BEYOND.

.AVIATION...
THERE IS THE POSSIBILITY OF MVFR CEILINGS DEVELOPING AND LINGERING
EARLY THIS MORNING NEAR KCPR...BUT SHOULD QUICKLY DISSIPATE SHORTLY
AFTER 12Z.  HOWEVER...MORE OF A CONCERN WILL BE THE POSSIBILITY OF
FOG AT KJAC...THIS WILL DEPEND IF THE CURRENT STRATOCU JUST ABOVE
MVFR SCATTERS OUT FOR RADIATIONAL COOLING.  LIGHT WINDS...SMALL
DEWPOINT SPREAD AND RECENT MOISTURE SHOULD PRIME STAR
VALLEY...JACKSON HOLE AND YELLOWSTONE FOR DENSE FOG. FOG SHOULD
DISSIPATE BY 16Z. OTHERWISE...VFR ARE EXPECTED ACROSS THE REST OF THE
AREA...WITH WIND INCREASING...ESPECIALLY FOR KCOD AND KCPR LATE IN
THE AFTERNOON AND MONDAY NIGHT...AHEAD OF A VERY STRONG STORM SYSTEM
MOVING ACROSS CANADA AND THE NORTHERN ROCKIES.

.FIRE WEATHER...
CLEARING SKIES...AND DRY CONDITIONS WILL BE FOUND OVER THE AREA
TODAY...WITH SOME PATCHY FOG POSSIBLE ACROSS THE NORTHWEST DURING
THE MORNING HOURS. TEMPERATURES WILL BE JUST SLIGHTLY COOLER THAN
YESTERDAY...THOUGH ARE EXPECTED TO REBOUND TO THE LOW 50S ON
TUESDAY. MEANWHILE... AN INCREASED PRESSURE GRADIENT WILL MOVE INTO
THE AREA ON MONDAY NIGHT AND TUESDAY MORNING...BRINGING VERY STRONG
WINDS OVER FAVORED AREAS. A HIGH WIND WATCH HAS BEEN ISSUED FOR THE
ABSAROKA MOUNTAINS...CODY FOOTHILLS...THE EASTERN SLOPES OF THE WIND
RIVER AND BIGHORN MOUNTAINS...ALONG WITH NATRONA COUNTY AND THE
GREEN MOUNTAINS AND RATTLESNAKE RANGE. LOWER ELEVATIONS IN THESE
AREAS MAY SEE WINDS OF 40 GUSTING TO AROUND 60...WITH MOUNTAIN
LOCATIONS SEEING WINDS OF 50 MPH. IN ADDITION TO WINDS...SHOWER
ACTIVITY WILL MOVE INTO WESTERN WYOMING MONDAY NIGHT...AND WILL
BRINGING SNOW SHOWERS OVER THE WESTERN MOUNTAINS AND VALLEYS BY
TUESDAY MORNING. THE STRONG WINDS SHOULD WEAKEN TO BELOW ADVISORY
LEVELS BY TUESDAY EVENING...THOUGH SHOWER ACTIVITY WILL CONTINUE
THROUGHOUT THE NIGHT AND INTO WEDNESDAY. INCREASED DAYTIME CLOUD
COVER WILL KEEP TEMPERATURES COOLER ON WEDNESDAY...WITH ELEVATED
HUMIDITIES EXPECTED THROUGH MUCH OF THE FORECAST PERIOD...ESPECIALLY
