AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
1124 AM MST THU DEC 29 2011

.UPDATE...
STARTING TO SEE MUCH IMPROVED CONDITIONS LATE THIS MORNING
ACROSS FAR WESTERN WYOMING...ESPECIALLY PARTS OF YELLOWSTONE
NATIONAL PARK. STRONG WINDS WILL CONTINUE MOST AREAS BUT
SNOWFALL WILL NOT. THIS BREAK IS DUE TO DRIER AIR MOVING
INTO THE STATE WITH SHORT WAVE RIDGING ALOFT. THEREFORE...
WILL SOON CANCEL WINTER WEATHER HIGHLIGHTS. LATE AFTERNOON
DISCUSSION WILL REINTRODUCE SNOWFALL FOR WESTERN WY.

PREV DISCUSSION... /ISSUED EARLY THURSDAY AM/

SHORT TERM...TODAY THROUGH SATURDAY NIGHT

A RELATIVELY WARM AND MOIST WINTER STORM CONTINUES TO IMPACT THE
WESTERN PORTIONS OF THE CWA TODAY. THE LOWER ELEVATIONS OF THE
WEST RECEIVED MAINLY RAIN FROM THIS EVENT...PROMPTING THE
CANCELLATION OF THE WINTER STORM WARNINGS FOR THE LOWER ELEVATIONS
OF THE WEST...AND THE WINTER WEATHER ADVISORY FOR THE DUBOIS AREA.
THERE CONTINUES TO BE A HEALTHY STREAM OF MOISTURE EVIDENT IN
SATELLITE IMAGERY...SO THERE IS NO NEED TO PREMATURELY CANCEL THE
WARNINGS FOR THE MOUNTAIN ZONES.

THE NEXT SYSTEM COMING IN ON FRIDAY APPEARS TO BEGIN AS A WARM
SYSTEM AS WELL...SNOW AMOUNTS HAVE BEEN SHAVED DOWN IN THE LOWER
ZONES AS A RESULT. A MENTION OF RAIN HAS ALSO BEEN ADDED. THIS
NEXT SYSTEM WILL HAVE A DECENT COLD FRONTAL PASSAGE WITH IT SO
MENTION OF RAIN HAS BEEN REMOVED WITH FROPA AND SNOW RATIOS
INCREASED ABOVE 10 TO 1. THE NEXT SYSTEM COULD ALSO LEAVE A LIGHT
DUSTING OF SNOW EAST OF THE DIVIDE LATER IN ITS EVOLUTION
..HIGHLIGHTS MAY AGAIN BE NECESSARY FOR THE WESTERN MOUNTAINS BUT
NONE ARE ANTICIPATED FOR AREAS EAST OF THE DIVIDE...AT LEAST NOT
FOR SNOW.

WINDS WILL CONTINUE TO BE ELEVATED INTO THE WEEKEND. HAVE EXTENDED
THE HIGH WIND WARNING FOR SOUTHEASTERN FREMONT COUNTY INCLUDING
THE 789 TRAVEL CORRIDOR BETWEEN BEAVER RIM AND MUDDY GAP...THROUGH
AT LEAST 06Z FRI. WESTERLIES WILL ALSO PICK UP IN EASTERN
SWEETWATER AS THIS FIRST TROUGH PASSES...THIS IS EXPECTED TO CAUSE
TRAVEL DIFFICULTIES ALONG I80 AND ANY ROADS LEADING SOUTH TO THE
COLORADO BORDER. THE NEXT SYSTEM WILL ALSO BE EXTREMELY
WINDY...THOUGH THERE APPEARS TO BE ENOUGH OF A LULL BETWEEN
SYSTEMS TO TREAT THEM AS TWO SEPARATE EVENTS. MORE WIND HIGHLIGHTS
ARE EXPECTED ON FRIDAY AS STRONG WINDS WILL AGAIN BECOME WIDESPREAD.

MUCH OF THE AREA WILL BE WINDY TODAY...WITH THE MOST OBVIOUS AREAS
ALREADY COVERED BY WARNINGS...THOUGH MORE MAY BE ADDED AS THE
SYSTEM EVOLVES TODAY...THESE AREAS HAVE BEEN COVERED BY SPECIAL
WEATHER STATEMENTS AND WILL BE WATCHED CLOSELY.

LONG TERM...NEW YEARS DAY THROUGH THURSDAY

NEW YEARS DAY...A SLIGHT CHANCE OF SNOW/FLURRIES IN THE
WEST...OTHERWISE DRY AND COOL WITH HIGHS MOSTLY IN THE 20S TO
LOWER 30S.

MONDAY THROUGH THURSDAY...A SLIGHT CHANCE OF SNOW IN THE WESTERN
MOUNTAINS TUESDAY.  OTHERWISE DRY AND WARMER IN WIND CORRIDORS WITH
TEMPERATURES LAGGING IN FAR WEST VALLEYS AND CENTRAL BASINS.

MEDIUM RANGE GLOBAL MODELS ARE IN BETTER AGREEMENT THIS MORNING WITH
TIMING OF SHORTWAVES THROUGH MERIDIONAL LONGWAVE PATTERN FEATURING
UPPER RIDGE OVER THE INTERMOUNTAIN WEST FLANKED BY TROUGHS OVER THE
EASTERN PACIFIC AND EASTERN U.S. THE MAIN SHORTWAVE ADVERTISED IN
THIS FLOW WILL EJECT OVER THE RIDGE ACROSS THE NORTHERN ROCKIES
MONDAY NIGHT WITH NEXT UPSTREAM TROUGH PUSHING ONTO WEST COAST
THURSDAY. WARM ADVECTION...UPGLIDE PATTERN WITH LIMITED
MOISTURE...SETS UP ACROSS THE WEST SUNDAY WITH STRATIFORM CLOUDS
AND POSSIBLY SOME LIGHT SNOW OR FLURRIES. PASSING HIGH CLOUDS AND
LIGHT WINDS WITH SURFACE HIGH PRESSURE OVER THE NORTHERN HIGH
PLAINS WILL RESULT IN LIMITED INSOLATION AND MIXING WITH
TEMPERATURES REMAINING BELOW NORMAL. A LEE SIDE SURFACE
TROUGH...INCREASING WINDS ALOFT AND LESS CLOUD COVER WILL ALLOW
TEMPERATURES TO WARM UP MONDAY...MORESO THROUGH WIND CORRIDORS
THAN PROTECTED WESTERN VALLEYS AND BASINS. BETTER MIXING POSSIBLE
ON TUESDAY WITH SHORTWAVE AND ASSOCIATED PACIFIC COLD FRONTAL
PASSAGE IN THE MORNING. UPPER RIDGE REBUILDS OVER AREA WEDNESDAY
WITH BREEZY AND UNSEASONABLY WARM WEATHER THROUGH WIND
CORRIDORS...TEMPERATURES REMAINING NEAR OR SLIGHTLY ABOVE NORMAL
IN CENTRAL BASINS AND WESTERN VALLEYS. GFS IS MORE SPLIT WITH NEXT
PACIFIC TROUGH APPROACHING THE WEST COAST THURSDAY...WITH ECMWF
SHOWING A BIT MORE PROGRESSION OVERALL WITH TROUGH ALONG WEST
COAST BY 00Z FRIDAY. A WARM AND DRY SOUTHWEST FLOW PRECEDES THIS
TROUGH ON THURSDAY.

AVIATION.../18Z ISSUANCE/

CHANGES ARE NEEDED OVER THE NEXT SIX HOURS OR SO IN REGARDS TO
WEATHER ACROSS WEST CENTRAL WYOMING. CLOUDS WILL DECREASE MOST
AREAS THIS AFTERNOON. WEST OF THE DIVIDE TO BRIEFLY BECOME VFR
WITH EAST REMAINING WINDY WITH VFR CONDITIONS. AGAIN...ANOTHER
STORM ENTERS FAR WESTERN WYOMING TONIGHT.

FIRE WEATHER...

SIGNIFICANT PRECIPITATION IN THE WEST AND SIGNIFICANT WIND IN THE

TONIGHT THROUGH FRIDAY. TEMPERATURES WILL BE LITTLE CHANGED
THROUGH THE DAY TODAY THEN COOLING ON FRIDAY...REMAINING COOL ON
SATURDAY. LOW MIXING HEIGHTS AND EXTENSIVE CLOUD COVER AND
SNOWFALL IN THE WEST WILL PRODUCE POOR SMOKE DISPERSAL. THE
WINDIER AREAS EST OF THE DIVIDE WILL SEE FAIR TO GOOD SMOKE
DISPERSAL THURSDAY. RELATIVE HUMIDITY WILL BE FAVORABLE TO HIGH
ACROSS THE AREA.
