AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
311 PM MST TUE DEC 27 2005

.SHORT TERM...TONIGHT THROUGH FRIDAY...
LIGHT SNOW ALREADY FALLING OVER THE FAR WEST AS LEADING EDGE OF
MOISTURE AND ISENTROPIC LIFT MOVES QUICKLY IN. STILL LOOKS LIKE ANY
HEAVIER SNOW WILL HOLD OFF UNTIL AFTER 06Z FOR THE TETONS...SALT AND
WYOMING RANGES...WHEN STRONGER ISENTROPIC BEGINS TO ARRIVE. AM
COUNTING ON ONLY LIGHT ACCUMULATION IN THE STAR AND JACKSON VALLEYS
OVERNIGHT. AS THE WARM ADVECTION GETS INTO FULL SWING TOMORROW
MORNING...TEMPERATURES ARE LIKELY TO GET WARM ENOUGH IN THE STAR
VALLEY TO CHANGE MANY AREAS OVER THE RAIN BY AFTERNOON. THE JACKSON
VALLEY IS RIGHT ON THE EDGE AND AM EXPECTING TEMPERATURES TO TOP OUT
IN THE MID 30S. DEBATED A WINTER STORM WATCH FOR BOTH OF THESE AREAS
WITH JACKSON BEING THE HARDER CHOICE BUT HAVE OPTED AGAINST IT SINCE
WHAT SNOW FALLS TONIGHT COULD MELT TOMORROW BEFORE HEAVIER SNOW MOVES
BACK IN DURING THE EVENING. EVENING CREW WILL JUST HAVE TO KEEP A
CLOSE WATCH ON THIS. ALSO EXPECT ADVISORIES TO BE NEEDED IN THE REST
OF THE WEST BY WEDNESDAY MORNING. SOME WARNING AMOUNTS ARE QUITE
POSSIBLE ALONG THE NORTH END OF THE WINDS...INCLUDING TOGWOTEE
PASS...THE SOUTHWEST PORTION OF THE ABSAROKAS AND POSSIBLY THE NORTH
END OF THE JACKSON VALLEY. EVEN THE HIGHER PEAKS OF YNP COULD SEE
OVER 12 INCHES BUT NOT THE ENTIRE AREA. GENERALLY USED THE GFS AS
GUIDANCE TODAY DUE TO BETTER INITIALIZATION AND FASTER SPEED WHICH IS
WORKING OUT ALREADY.

COLD FRONT SHOULD CHANGE ANY MIXTURE OVER TO ALL SNOW AFTER 00Z
TOMORROW IN THE FAR WEST WITH FRONT BLOWING THROUGH THE REST OF THE
AREA OVERNIGHT. STRONGEST WINDS SHOULD OCCUR WITH COLD FRONTAL
PASSAGE WITH LOTS OF BLOWING AND DRIFTING SNOW AT PEAK AND PASS
LEVEL. ALTHOUGH THE HIGHER MOUNTAINS WILL SEE WINDY CONDITIONS
TONIGHT AND WEDNESDAY. SOUTH PASS SHOULD HOLD OFF ON THE WORST
CONDITIONS UNTIL TOMORROW EVENING WITH DETERIORATING CONDITIONS
POSSIBLE BY LATE AFTERNOON. THE FAR WEST MOUNTAINS WILL LIKELY
CONTINUE WITH SOME LIGHT SNOW OR FLURRIES THURSDAY AND FRIDAY
BEFORE THE NEXT SYSTEM MOVES IN. SEE DISCUSSION BELOW FOR DETAILS ON
THAT.

.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY...
GFS AND ECMWF MEDIUM RANGE GUIDANCE CONTINUES IN OVERALL GOOD
AGREEMENT AND REMAINING CONSISTENT FOR THE EXTENDED FORECAST EVEN
WITH A FAST/PROGRESSIVE PATTERN. AFTER SOME BRIEF RIDGING WORKING
OVERHEAD FRIDAY FOR LOWERED PRECIP CHANCES...NEXT SYSTEM MOVES ONTO
WEST COAST SATURDAY. WITH AN INCREASING MOIST SOUTHWESTERLY
FLOW...THIS IS YET ANOTHER SYSTEM THAT PROMISES MORE SNOWFALL FOR
LOCATIONS WEST OF DIVIDE BEGINNING FRIDAY NIGHT...BUT ESPECIALLY
SATURDAY AND SATURDAY NIGHT. WITH THE CONSISTENCY OF MODELS...HAVE
CONTINUED TO INCREASE PRECIP CHANCES FOR THIS TIME FRAME. WITH SHORT
WAVE TROUGH PASSAGE ACROSS THE STATE NEW YEARS DAY...A FEW SNOW AND
EVEN RAIN SHOWERS COULD SPILL OVER TO AREAS EAST OF DIVIDE. VERY
BRIEF UPPER LEVEL RIDGING SHOULD TAPER PRECIP OFF SUNDAY NIGHT...BUT
THE WEST SHOULD QUICKLY RETURN TO INCREASED SNOW CHANCES INTO EARLY
NEXT WEEK AHEAD OF ANOTHER SYSTEM MOVING ONTO THE WEST COAST MONDAY.
NOT A LOT OF TEMPERATURE FLUCTUATIONS WITH THE PROGRESSION OF THESE
PACIFIC SYSTEMS. HAVE ONLY MADE MINOR ADJUSTMENTS AS TIMING OF SYSTEM
BECOMES MORE CLEAR. OVERALL...ABOVE NORMAL TEMPERATURES WILL PREVAIL
ESPECIALLY IN DRIER AREAS EAST OF DIVIDE.
