AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
318 PM MST SUN DEC 2 2007

.SHORT TERM...TONIGHT THROUGH WEDNESDAY
ACTIVE SHORT TERM FORECAST ONCE AGAIN AS HIGH WIND POTENTIAL
EXISTS NEAR THE CODY FOOTHILLS FROM LATER THIS EVENING ALL THE WAY
INTO TUESDAY MORNING AND NEAR THE GREEN MOUNTAINS AND RATTLESNAKE
RANGE LATER TONIGHT THROUGH MONDAY. WILL LET THE EVENING CREW MAKE
THE FINAL CALL ON THE FIRST PART OF THESE HIGH WIND WATCHES. FOR
ZONE 19...WOULD LIKE TO MAKE SURE MORE SURFACE GRADIENT IS GOING
TO DEVELOP THIS EVENING BEFORE PULLING THE TRIGGER. BEAVER RIM
SENSOR IS THE ONE AREA THAT IS NEAR OR AT HIGH WIND CRITERIA WHILE
THE REST OF THE AREA GENERALLY HAS A WAYS TO GO YET. BEST
POTENTIAL SHOULD BE LATER THIS EVENING INTO MONDAY BEFORE H7 WINDS
TURN NW. OTHER AREA OF CONCERN CONTINUES TO BE THE CODY FOOTHILLS
AND EAST SLOPE OF THE ABSAROKA WHERE VERY WINDY PERIOD APPEARS TO
BE IN STORE INTO TUESDAY MORNING WITH THE HIGHEST RISK OF DAMAGING
WINDS BEING MONDAY NIGHT INTO TUESDAY MORNING. CROSS SECTIONS
SHOWING STABLE LAYER NEAR MTN TOP BUT NOT SEEING THE NECESSARY
INVERSIONS ON THE SOUNDINGS YET. FROUDE CALCULATIONS ARE IN THE
.90 TO 1.00 RANGE TONIGHT BASED ON OUR INPUT. POTENTIAL FOR AT
LEAST LOCALIZED MOUNTAIN WAVE CONDITIONS STILL EXISTS TONIGHT AND
MONDAY. WITH THE RECENT DOWNSWING IN WIND SPEEDS AND
UNCERTAINTY...WILL ALLOW THE EVENING CREW TO LOOK AT THE LATEST
00Z DATA BEFORE DECIDING WHETHER TO UPGRADE OR NOT. THE
POTENTIALLY MORE DAMAGING WIND EVENT STILL SEEMS TO BE SET UP FOR
MONDAY NIGHT WITH SIGNIFICANT MTN TOP STABLE LAYER...SUFFICIENT
WIND SPEED...FROUDE NUMBERS NEAR 1 AND IMPRESSIVE CROSS BARRIER
THERMAL GRADIENT FOR IMPRESSIVE CHINOOK SETUP AND POTENTIAL JET
PASSING JUST TO THE NORTH.

IN THE FAR WEST...SNOW WILL INTENSIFY LATER TONIGHT OR MONDAY
MORNING AND CONTINUE THROUGH MONDAY NIGHT WITH POTENTIAL FOR HEAVY
SNOW AT HIGH END SNOW ADVISORY OR EVENING WARNING CRITERIA. IT IS
A LITTLE WARM FOR OPTIMAL SNOW CRYSTAL GROWTH WHICH IS ONE
NEGATIVE. DEBATED A WINTER STORM WATCH FOR MONDAY AND MONDAY NIGHT
BUT OPTED FOR TO INPUT SOLID SNOW ADVISORY AMOUNTS FOR NOW. I
FULLY EXPECT WE WILL NEED AT LEAST AN ADVISORY BY MONDAY MORNING
OUT WEST IN THE MOUNTAINS. THE VALLEYS WILL BE TRICKY AS THE WARM
AIR MOVES IN AND TEMPERATURES WARM TO NEAR FREEZING MONDAY AFTERNOON.
BRIEF DECREASE LIKELY TUESDAY IN ADVANCE OF NEXT SYSTEM CLIPPING
NE WYO TUESDAY NIGHT AND WEDNESDAY AND A MORE SIGNIFICANT SYSTEM
IMPACTING THE AREA LATER WEDNESDAY AND INTO THE FIRST PART OF THE
EXTENDED PERIOD. TRICKY TEMPERATURE AREAS WILL BE THE BASINS LIKE
THE WIND RIVER AND BIG HORN WITH INCREASING PRESSURE GRADIENT BUT
SNOW COVER AND LOW LEVEL INVERSIONS. USUALLY THE INVERSIONS WIN
BUT STILL CONCERNED FOR ESPECIALLY THE WIND RIVER BASIN WITH NW
FLOW INCREASING WHICH COULD WORK ITS WAY DOWN FROM DUBOIS
EVENTUALLY. WILL BE VERY INTERESTING TO SEE HOW THESE MONDAY AND
TUESDAY TEMPERATURES PAN OUT IN THESE AREAS. FOR NOW HAVE KEPT THE
PREVIOUS SHIFTS TRENDS BUT IT NEEDS TO BE WATCHED.

.LONG TERM...WEDNESDAY THROUGH SUNDAY
BETTER AGREEMENT WITH THE LONG RANGE MODELS WED THRU FRI. A
WEATHER SYSTEM MOVES INTO THE PACIFIC NW STATES WED AND INTO THE
NORTHERN ROCKIES WED NIGHT. THIS WILL LEAD TO A GOOD CHANCE OF
SNOW FOR THE MTS AND A SLIGHT CHANCE OF SNOW AT THE LOWER
ELEVATIONS...MAINLY WED NIGHT. THE SYSTEM MOVES THROUGH ON THURS.
A CHANCE OF LT SNOW IN THE MORNING WITH IMPROVING CONDITIONS IN
THE AFTERNOON FROM NW TO SE ACROSS THE REGION. MOSTLY DRY THURS
NIGHT WITH SOME FLURRIES IN THE MTS. LITTLE BIT OF RIDGING FOR
FRIDAY AS THE FLOW ALOFT BACKS TO THE SW. MODELS DEVELOP AN UPPER
LOW ALONG OR JUST OFF THE CALIFORNIA COAST FRIDAY. NOT SURE HOW
MUCH MOISTURE WILL FILTER INTO THE AREA FRI PM. PLUS THE MODELS
WISH TO SEND A SHORTWAVE THROUGH THE FLOW FRI NIGHT. FOR NOW WILL
KEEP LOW PRECIP CHANCE IN THE WESTERN MTS AND THE WESTERN VALLEYS.
WILL HAVE LOW PRECIP CHANCES FOR FRI NIGHT PROVIDED THE SHORTWAVE
MOVES THROUGH THE AREA. SATURDAY APPEARS TO BE A DRIER DAY FOR NOW
WITH SOME MOUNTAIN SNOW SHOWERS POSSIBLE. GFS AND ECMWF MODELS
DIFFER NEXT SUN WITH GFS HAVING THE LOW OFF SRN CALIFORNIA WHILE
THE ECMWF PICKS IT UP AND MOVES IT INTO ARIZONA. IN THE NORTHERN
STREAM...THE GFS BRINGS A SYSTEM ACROSS MONTANA WHILE THE ECMWF IS
DEEPER WITH A TROUGH MOVING INTO THE NORTHERN ROCKIES AT 00Z MON.
WILL HAVE PRECIP CHANCE IN THE MTS AND OVER THE NORTH ZONES. AS
FOR TEMPS...SEASONAL HIGHS AND LOW THROUGH THE PERIOD. SOME AREAS
WILL BE MILDER DUE TO SOME WIND AT TIMES.

&&

.AVIATION...
VERY WINDY CONDITIONS EXPECTED AT OR INVOF KCPR AND KCOD OVERNIGHT
INTO THE MONDAY.  WIND SPEEDS OF 30-40KTS WITH GUSTS APPROACHING 50
KTS POSSIBLE IN THESE AREAS.  OTHERWISE...BREEZY TO WINDY CONDITIONS
EXPECTED FOR KJAC AND KRKS...WITH LIGHT WINDS AT THE REMAINING TAF
SITES.  SNOW WILL INTENSIFY TONIGHT IN THE WEST...PRIMARILY
AFFECTING KJAC...BUT COULD SPREAD TO KBPI AND KPNA MONDAY.  EXPECT
MVFR CIGS AND VSBYS WITH THE SNOW.

&&

.FIRE WEATHER...
STRONG SOUTHWEST WINDS WILL DOMINATE THE WIND CORRIDOR FROM THE
RED DESERT TO CASPER THE NEXT COUPLE DAYS WITH POTENTIAL HIGH
WINDS NEAR THE GREEN MOUNTAINS AND RATTLESNAKE RANGE. THE CODY
FOOTHILLS AND NEARBY EAST SLOPE OF THE ABSAROKA MOUNTAINS WILL BE
ANOTHER VERY WINDY AREA INTO TUESDAY MORNING. IN THE FAR WEST...
SNOW WILL FALL IN THE MOUNTAINS THROUGH AT LEAST MONDAY NIGHT WITH
THE HEAVIEST FALLING MONDAY AND MONDAY NIGHT ALONG WITH STRONG
PEAK LEVEL WINDS. TEMPERATURES WILL WARM CONSIDERABLY OVER THE
NEXT 24 TO 36 HOURS.
