1028 PM MST MON NOV 3 2014

.SHORT TERM...TONIGHT AND TUESDAY (ISSUED AT 309 PM MST)

CURRENT SYSTEM WHICH MOVED OVER OUR SERN SECTIONS OVERNIGHT IS
PULLING OFF TO THE EAST WITH JUST SOME RESIDUAL STRATOCU FORMING
BEHIND THE MORNING CLOUD DECK. BRIEF FLAT RIDGING TONIGHT AND
TUESDAY MORNING HEAD OF AHEAD OF AN APPROACHING SHORTWAVE. MOIST
ISENTROPIC UPGLIDE MOVES INTO THE WEST AROUND MIDDAY WITH A HIGH
POP LOW QPF TYPE EVENT FOR THE NW MTNS. JACKSON VALLEY WILL BE ON
THE EDGE TEMPERATURE WISE FOR RAIN SNOW TUESDAY AFTERNOON. WINDS
KICK IN AN POTENTIALLY MIX THE VALLEY OUT MAKING IT MORE RAIN OR A
MIXTURE BUT STILL A CHANCE IT COULD BE SNOW. THE OTHER MAIN EVENT
WILL BE POTENTIAL FOR HIGH WINDS IN THE CODY FOOTHILLS TUESDAY
AFTERNOON AND TUESDAY NIGHT. COLLABORATED A HIGH WIND WATCH WITH
MY LONG TERM PARTNER WHICH STARTS AT 18Z TUESDAY AND RUNS UNTIL
12Z WEDNESDAY. LCL WRF AND NAM12 ARE SHOWING SEVERAL PERIODS OF A
NEAR MTN TOP INVERSION TUESDAY AFTERNOON AND AGAIN TUESDAY NIGHT
WITH A POSSIBLE BREAK IN BETWEEN. FROUDE CALCULATIONS LOOK MORE
FAVORABLE FOR THE MTNS UNDER 10K FEET WITH THE NUMBER RATHER LOW
FOR THE HIGHER ABSAROKA PLATEAU. MODERATE GAP FLOW SIGNATURE ALSO
DEVELOPS IN THE +12C AT H7 LEVEL LATE TUESDAY AND INTO TUESDAY
NIGHT. RIGHT FRONT QUAD OF 140-150KT JET MOVES OVERHEAD TUESDAY
AFTERNOON FOR POTENTIAL UPPER CONVERGENCE AND DOWNWARD MOTION
SUPPORT. LCL WRF IS GIVING WIDESPREAD 30-35KT BOUNDARY LAYER WINDS
WITH SOME 40KTS NEAR THE HIGHWAY NORTH OF CODY AND 50KTS JUST TO
THE WEST. ENOUGH SUPPORT/SIGNATURES TO WARRANT THE WATCH FOR NOW.
OTHERWISE...A COLD START AS TEMPERATURES DIP QUICKLY THIS EVENING.
SOME AREAS OF WIND WILL TEMPER A FEW AREAS BUT ANY LULLS WILL EVEN
ALLOW THOSE AREAS TO DROP QUICKLY AT TIMES. SEASONABLY COOL
TUESDAY WITH SOME INVERSIONS IN THE BASINS AND WRN VALLEYS SLOW TO
ERODE.

.LONG TERM...TUESDAY NIGHT THROUGH MONDAY

COLLABORATED TO CONTINUE THE HIGH WIND WATCH ACROSS THE CODY
FOOTHILLS THROUGH 12Z WEDNESDAY. WINDS MAY DIMINISH SLIGHTLY
BETWEEN 03Z-06Z TUESDAY NIGHT...BUT THEY LOOK TO RESUME NEAR HIGH
WIND CRITERIA BY 09Z...HENCE THE CONTINUATION UNTIL 12Z.
OTHERWISE...WEAK WAVE...WITH SOMEWHAT MOIST WESTERLY FLOW...WILL
CONTINUE LIGHT SNOW ACROSS THE WEST THROUGH TUESDAY NIGHT...INTO
WEDNESDAY MORNING. IN ADDITION...A QUICK CLIPPER SYSTEM PUSHING
ACROSS EASTERN MT AND WESTERN DAKOTAS...COULD BRING A WEAK
BACKDOOR COLD FRONT ACROSS NORTHERN JOHNSON COUNTY...OVERNIGHT
TUESDAY NIGHT THROUGH WEDNESDAY MORNING. ADDED IN A SLIGHT CHANCE
OF LIGHT RAIN...AND POSSIBLE SOME FLURRIES...WITH THIS FEATURE. BY
WEDNESDAY AFTERNOON HIGH PRESSURE WILL PUSH INTO THE
REGION...ENDING ANY PRECIPITATION...AND BRING DIMINISHING WINDS.
THURSDAY THEN LOOKS TO BE THE WARMEST DAY OF THE WEEK...WITH HIGHS
IN THE LOW TO MID 60S FORECASTED...AS HIGH PRESSURE RIDGE BRINGS WARM
AND DRY AIR. AS THE RIDGE FLATTENS IN THE AFTERNOON...SOME BREEZY
CONDITIONS MAY DEVELOP ACROSS THE WIND CORRIDOR FROM ROCK SPRINGS
TO CASPER...THURSDAY AFTERNOON AND EVENING.

THE NEXT CHANCE OF PRECIPITATION WILL OCCUR ON FRIDAY AS A
CANADIAN COLD FRONT PUSHES FROM NORTH TO SOUTH OUT OF
MONTANA...LATE FRIDAY MORNING...THROUGH FRIDAY EVENING. SNOW
LEVELS WILL GENERALLY BE ABOVE 7000-7500 FEET DURING THE DAY WITH
THIS SYSTEM...SO MOST AREAS EAST OF THE DIVIDE WILL SEE MAINLY
RAIN...WITH SOME LIGHT SNOW POSSIBLE ACROSS THE WESTERN MOUNTAINS. RAIN
COULD CONTINUE INTO THE EVENING...WITH A FEW FLURRIES POSSIBLE AS
PRECIP ENDS FRIDAY NIGHT. HIGH PRESSURE THEN RETURNS WARM AND DRY
CONDITIONS ACROSS THE REGION SATURDAY...WITH SOME BREEZY WINDS
AGAIN POSSIBLE ACROSS THE WIND CORRIDOR. LONG TERM MODELS START
SUNDAY WARM AND DRY...THEN DIVERGE FROM THERE. GFS BUILDS ANOTHER
RIDGE AND KEEPS CONDITIONS FAIRLY DRY AND SEASONAL INTO EARLY NEXT
WEEK. ECMWRF HAS THIS RIDGE BREAKING DOWN...AND BRINGS A STRONG
COLD FRONT ACROSS THE REGION WITH AMPLE COLD AIR. WITH 700 MB
TEMPS IN THE NEGATIVE TEENS...THIS ALSO COULD BRING AN AMPLE
AMOUNT OF SNOW ACROSS THE REGION. PUT IN SLIGHT POPS FOR NOW...BUT
IT IS SOMETHING THAT WILL NEED TO BE MONITORED.
