310 PM MST FRI NOV 15 2013

.SHORT TERM...TONIGHT THROUGH SATURDAY

THINGS WILL BECOME ACTIVE AS THE NEXT WINTER WEATHER MAKER MOVES
FROM THE PACIFIC NORTHWEST INTO THE WYOMING THROUGH TONIGHT AND INTO
SATURDAY. SNOW SHOWERS...SOME HEAVY...HAVE DEVELOPED OVER SWEETWATER
COUNTY THIS AFTERNOON WITH A JET STREAK MOVING ACROSS NORTHERN
COLORADO. THESE SHOULD END LATER THIS AFTERNOON WITH MOST OF THE
AREA SEEING MAINLY DRY WEATHER THROUGH AROUND MIDNIGHT TONIGHT.

WEST OF THE DIVIDE...THE FIRST WAVE WILL MOVE INTO WESTERN WYOMING
AFTER MIDNIGHT TONIGHT AND SPREAD SNOW FROM NORTHWEST TO SOUTHEAST
ACROSS THE WESTERN MOUNTAINS AS WELL AS SOME OF THE ADJACENT
VALLEYS. THERE IS A DECENT AMOUNT OF DYNAMICS WITH THIS SYSTEM SO
SNOWFALL RATES WILL LIKELY BECOME MODERATE TO LOCALLY HEAVY AT
TIMES. AS A RESULT...WE WILL HOIST WINTER WEATHER ADVISORIES ACROSS
MUCH OF THE AREAS WEST OF THE DIVIDE WITH A GENERAL 6 TO 10 INCHES
IN THE MOUNTAINS AND 3 TO 6 INCHES IN THE VALLEYS. THERE COULD BE
LOCALLY HIGHER AMOUNTS IN THE HIGHER ELEVATIONS OF THE TETONS...BUT
THIS SHOULD BE ABOVE PASS LEVEL. NEVERTHELESS...A DIFFICULT TRAVEL
DAY ACROSS THE WESTERN WYOMING WITH SNOW AND AREAS OF BLOWING SNOW.
SNOW WILL CONTINUE OFF AND ON THROUGH THE DAY WITH POSSIBLY A PERIOD
OF HEAVY SNOW LATER IN THE AFTERNOON AS THE MAIN TROUGH AXIS PASSES
THROUGH WITH THE BEST OMEGA. SNOWFALL RATES SHOULD TAPER OFF AFTER
THAT ALTHOUGH UPSLOPE FLOW KEEP SNOW SHOWERS GOING INTO THE EVENING.

EAST OF THE DIVIDE...THE CONCERN HERE WILL BE NOT FOR SNOW BUT FOR
WIND. THE PRESSURE GRADIENT WILL TIGHTEN AS A COLD FRONT WITH THE
SYSTEM PRODUCING THE SNOW ACROSS THE WEST MOVES IN. WINDS ALOFT WILL
ALSO BE RATHER STRONG WITH THE NAM SHOWING 50 TO 55 KNOTS AT 500
MILLIBARS ACROSS PORTIONS OF EASTERN FREMONT COUNTY AS WELL AS MUCH
OF NATRONA COUNTY. WITH GOOD MIXING CONDITIONS EXPECTED WE WILL
HOIST A HIGH WIND WATCH AS WELL ACROSS NATRONA COUNTY AS WELL AS THE
GREEN AND RATTLESNAKE RANGE FROM LATE MORNING INTO THE AFTERNOON.
GUSTY WINDS ARE POSSIBLE ELSEWHERE AS WELL ALTHOUGH NOT AS STRONG.
BUT NEVERTHELESS A DAY TO STRAP UP YOUR HAT OR GLUE DOWN YOU TOUPEE.

.LONG TERM...SATURDAY NIGHT THROUGH FRIDAY

CURRENTLY...SAT IMAGERY SHOWING SHOWING UPR SW MOVING THRU LARGE
SCALE LW TROF IN PLACE OVR CONUS...CUTTING DIAGONALLY FROM ECNTRL MT
THRU SWRN WY AND INTO SRN CA. UPR JET FORCING NOT AN ISSUE ATTM AS
BOT SRN AND NRN BRANCHES ARE WELL AWAY FROM THE FA...ONE JUST
PLOWING INTO THE NW CONUS/SRN BC...THE OTHER WELL SOUTH THRU BAJA
AND SRN STATES. AT SFC...HI PRESS W...LEE TROF E WITH DEVELOPING
CYCLONE  CURRENTLY FORMING IN BC.

SAT NIGHT...STRONGEST UPR LVL SW TROF WILL BE MOVING THRU...EXITING
BY SUN MORNING...WITH CANADIAN SFC CYCLONE STARTING TO BEAR DOWN AND
REDEVELOP IN THE NRN/CNTRL PLAINS. SNOW WILL STILL REMAIN
LIKELY...BUT BECOME LIGHT...ACROSS THE WRN MOUNTAINS OVERNIGHT SAT
THRU SUN MORNING...WITH CHCS DECREASING...PERHAPS QUICKER THAN IS
CURRENTLY IN THE FCST...THRU THE DAY ON SUNDAY. LOWER ELEVATIONS E
OF MOST MOUNTAIN RANGES...WILL  LARGE BE DEVOID OF ANY
PRECIP/SNOWFALL...OTHER THAN PERHAPS FLURRIES/VERY BRIEF LIGHT SNOW
SAT NIGHT. HAVE CUT BACK ON POPS SOMEWHAT IN THESE AREAS.
OTHERWISE...WINDS WILL START OUT QUITE STRONG SAT NIGHT...WITH
LARGELY UNIDIRECTIONAL FLOW THROUGH THE VERTICAL...QUITE UNSTABLE
LAPSE RATES...AND A SFC P GRAD APPROACHING 5-6 MB/100 MI...WITH WRLY
GUSTS AT THE LOWER ELEVATIONS IN THE 40 TO 50 MPH RANGE. WINDS WILL
DECREASE SOME OVERNIGHT SAT AND INTO SUN MORNING...BUT WILL
REINVIGORATE SUNDAY AFTERNOON...ALTHOUGH NOT TO THE SAME EXTENT AS
ON SAT.

BEYOND SUNDAY...UPR LVLS GO BRIEFLY NWRLY BEFORE TRANSITION TO
CONTINUED PROGRESSIVE BUT RATHER FLAT AND NEARLY ZONAL PATTER
MONDAY...WITH UPR LVL WAVE RIPPLES MOVING VERY QUICKLY THRU THE
PATTERN THRU THE REST OF THE FCST PERIOD. SO WRN MOUNTAINS WILL KEEP
LOW END POPS AROUND THRU MOST OF THE REST OF THE FCST...WITH
ADJUSTMENTS TO COME FOR SURE...AS INCOMING MOISTURE OSCILLATES OVR
TIME AND MAY NOT NECESSARILY MATCH UP WHEN BETTER DYNAMICS MOVE
ACROSS. LR MDLS WERE IN FAIR AGREEMENT THRU NEXT THU...BUT THAT WAS
BEFORE THE 12Z EURO CAME OUT...SO NOW THERE ARE SIGNIFICANT PHASING
DIFFERENCES BY WED OF NEXT WEEK. INTERESTINGLY...BOTH MDLS IN VERY
LONG TERM CONTINUE TO TREND TOWARD SIGNIFICANT RIDGING OVR THE
WRN CONUS BY THE BEGINNING OF T-GIVING WEEK...WHICH COULD BODE WELL
FOR TRAVEL...NOT SO MUCH FOR THE SKI AREAS.
