210 PM MST SAT NOV 22 2014

.SHORT TERM...TONIGHT THROUGH SUNDAY

A PACIFIC COLD FRONT APPROACHING WESTERN WYOMING WILL MOVE THROUGH
WESTERN AND CENTRAL WYOMING THROUGH THE NIGHT.  THE SNOW INTENSITIES
WILL DECREASE WITH THE PASSING OF THE COLD FRONT IN THE WESTERN
M0MOUNTAINS.  MOST AREAS EXPERIENCING HIGH WINDS TODAY WILL SEE
WINDS DECREASE AS THEY SHIFT TO THE NORTHWEST. HIGH WIND WATCHES
REMAIN FOR NORTHERN JOHNSON AND THE WIND RIVER BASIN WITH THE
NORTHWEST WINDS AS THESE AREAS FAVOR HIGH WINDS WITH NORTHWEST
WINDS AND COLD AIR ADVECTION. AREAS EAST OF THE CONTINENTAL DIVIDE
CAN EXPECT A QUICK BURST OF SNOWFALL BEHIND THE COLD FRONT WITH
LIGHT ACCUMULATIONS. OVERALL SNOWFALL WILL BE TAPERING OFF
THROUGH THE MORNING WITH SOME LINGERING MOUNTAIN SNOW SHOWERS ON
SUNDAY. TEMPERATURES WILL COOL ABOUT TEN DEGREES FROM TODAY.

.LONG TERM...SUNDAY NIGHT THROUGH SATURDAY

BEHIND THE MAIN SHORTWAVE THAT WILL BE SWINGING THROUGH THIS
WEEKEND...A SECONDARY PIECE OF ENERGY WILL BE SLIDING DOWN THE BACK
SIDE OF THE MAIN TROUGH AXIS ACROSS THE CWA FAIRLY QUICKLY AROUND
12Z MONDAY. WITH WEAK ISENTROPIC LIFT IN THE WEST AHEAD OF THIS
SYSTEM AS WELL AS SOME WEAK QG FORCING IN THE SOUTHWEST...KEPT IDEA
OF ANOTHER 3 TO 6 INCHES OF SNOWFALL IN THE WESTERN MTNS SUNDAY INTO
MONDAY ALONG WITH ANOTHER 2 TO 3 INCHES IN THE WESTERN VALLEYS. THE
SNOW INTENSITY WILL BEGIN TO DECREASE MONDAY AFTERNOON. DURING THE
TROUHPA...AROUND 12Z MONDAY...THERE WILL BE A BRIEF PERIOD WHEN THE
SNOWFALL SPILLS OVER TO AREAS EAST OF THE DIVIDE WITH THE MOST
SIGNIFICANT SNOWFALL OCCURRING IN THE BIG HORN MTNS WHERE 3 TO 5
INCHES ARE EXPECTED. THE SNOWFALL WILL DECREASE EAST OF THE DIVIDE
IN THE AFTERNOON AS WELL.

THE NEXT ANTICIPATED SNOW EVENT WILL OCCUR WHEN THE JET STREAM
SHIFTS NORTHEAST PLACING THE FASTER NORTHWEST FLOW ALOFT OVER
WYOMING BY 12Z TUESDAY. THIS WILL DRAW IN ADDITIONAL PACIFIC
MOISTURE FROM THE NORTHWEST ALONG WITH ISENTROPIC LIFT OVER WESTERN
WY TUESDAY WITH AN EXTENSIVE AREA OF ISENTROPIC LIFT SHIFTING TO OUR
NORTH OVER MONTANA BY TUESDAY NIGHT. THIS WILL JUSTIFY LIKELY POPS
IN THE WESTERN/BIG HORN MTNS AS WELL AS CHC POPS OVER THE NORTH HALF
OF THE LOWER ELEVATIONS OF THE CWA TUE/TUE NIGHT. THE JET STREAM
WILL THEN SHIFT NORTHEAST OF THE CWA BY WEDNESDAY.

AFTER THIS TIME FRAME...THE MODELS DIVERGE ONCE AGAIN WITH THE EURO
NOW THE MORE OPTIMISTIC MODEL PLACING A RIDGE OVER WY BY THURSDAY
AND THE GFS KEEPING THE DIRTY NORTHWEST FLOW OVER US THROUGH FRIDAY
WHICH IS IRONIC BECAUSE A COUPLE OF DAYS AGO BOTH THESE MODELS
PORTRAYED OPPOSITE SOLNS WITH THE GFS ADVERTISING A BUILDING RIDGE
AND THE EURO A POTENTIAL SNOW EVENT FOR THANKSGIVING. WITH THE
MODELS FLIP FLOPPING AND NO RUN TO RUN CONSISTENCY...ALL WE ARE
GOING TO DO IS INCREASE THE POPS A TAD OVER MAINLY NW WY FOR THE
SECOND HALF OF NEXT WEEK JUST IN CASE A SNOW EVENT DOES TAKE PLACE
DURING THIS TIME FRAME. MORE SPECIFICALLY...THE GFS PULLS IN COLDER
AIR FROM THE NORTHEAST OVER WY WITH MOST OF THE ASCT ISENTROPIC LIFT
FROM THIS ASCT WEATHER DISTURBANCE REMAINING TO OUR NORTH UP IN MT.

BY FRIDAY NIGHT...THE NW FLOW WILL BACK TO THE WEST AS THE RIDGE
FLATTENS. A MINOR DISTURBANCE MOVING THROUGH THE FLATTENING RIDGE
WITH ITS SHARE OF ISENTROPIC LIFT COULD BRING SOME LIGHT SNOW TO THE
FAR WEST SATURDAY.

TEMPERATURES NEXT WEEK WILL DEPEND LARGELY UPON WHETHER THE GFS OR
THE EURO PANS OUT SO KIND OF WENT WITH A BLEND. IN ANY EVENT...TEMPS
WILL BE MUCH MILDER THAN THEY HAVE BEEN DURING THE LAST COUPLE OF
WEEKS GIVEN THE LACK OF ANY ARCTIC INTRUSIONS NEXT WEEK.
