AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
1105 AM MST SAT JAN 28 2012

.SHORT TERM...TODAY THROUGH MONDAY NIGHT

WILL KEEP THE HIGH WIND WARNING GOING FOR THE ABSAROKA MTNS AND
THE ADJACENT CODY FOOTHILLS THROUGH 18Z THIS AFTERNOON...ALBEIT A
BORDERLINE EVENT. THE SENSOR AT DEAD INDIAN PASS ALONG THE CHIEF
JOSEPH HIGHWAY HAS BEEN REPORTING GUSTS OF 57 TO 62 MPH DURING THE
LAST COUPLE OF HOURS. THE RIGHT FRONT QUAD OF THE 130 KNOT JET MAX
WILL BE HELPING TO MIX THE WINDS DOWN TO THE SURFACE. A BETTER
SHOT OF HIGH WINDS APPEARS TO BE LIKELY IN THE SAME AREAS LATE
SATURDAY NIGHT INTO SUNDAY MORNING. THE LOCAL WRF HAS A 15 DEGREE
TEMPERATURE GRADIENT ACROSS THE ABSAROKA MTNS AT 700MB DURING THIS
TIME FRAME WHICH WOULD SUPPORT GAP FLOW. TRUE MOUNTAIN WAVE
ACTIVITY LOOKS MARGINAL WITH FROUDE NUMBERS ONLY LOOKING FAVORABLE
WHEN COMPUTED OFF THE LOWER FOOTHILLS SOUTH OF CLARK. THE OVERALL
GRADIENT LOOKS FAVORABLE WITH A 15MB GRADIENT FROM GCC TO RKS AS
WELL AS 5 ISOHYPES AT 700M SPACED APART EVERY 3 UNITS ACROSS
WYOMING DURING THIS TIME FRAME. SOME EVAPORATIVE COOLING FROM
SNOWFALL MAINLY ON THE WEST SIDE OF THE ABSAROKA MTNS WILL ENHANCE
THE WIND SPEEDS ON THE EAST SIDE OF THE ABSAROKAS. WILL INDICATE
AT LEAST BORDERLINE HIGH WINDS IN THESE AREAS IN THE GRIDS FOR NOW
FOR LATE TONIGHT AND SUNDAY MORNING AND WILL LET LATER SHIFTS LOOK
AT THE POSSIBILITY OF A HILITE FOR THESE AREAS TODAY TO AVOID
CONFUSION GIVEN THERE IS ALREADY A HIGH WIND WARNING IN EFFECT FOR
THE SAME AREAS NOW AS MENTIONED ABOVE. THE AFOREMENTIONED STRONG
GRADIENT WILL ALLOW WINDS TO INCREASE ALONG THE SOUTHERN WIND
CORRIDOR SUNDAY.

THE CLOSED CIRCULATION LOCATED AT 45N/146W WILL APPROACH THE COAST
AND FLATTEN THE RIDGE OVER THE EASTERN PACIFIC. AS THIS LOW MOVES
EAST TOWARD THE RIDGE...THE LOW WILL SWING A SHORTWAVE TOWARD THE
ROCKIES SUNDAY NIGHT AND MONDAY. INCREASING DIFLUENT BACKING
WESTERLY UPSLOPE FLOW OFF THE PACIFIC AHEAD OF THIS SYSTEM WILL
RESULT IN WIDESPREAD SNOWFALL OVER FAR WESTERN WYOMING SUNDAY NIGHT
AND MONDAY. KEPT LOW END ADVISORY AMOUNTS FOR NOW IN WESTERN WY BUT
ADDED ADDITIONAL SNOW AMOUNTS IN THE NORTHERN JACKSON AND STAR
VALLEYS. AS THE TROUGH AXIS APPROACHES...THE STEADY SNOW WILL BECOME
MORE CONVECTIVE AS LIFTED INDICES GO NEGATIVE IN NW WYOMING MONDAY
AFTERNOON. AS THE TROUGH MOVES EAST ACROSS WYOMING MONDAY
NIGHT...SNOWFALL WILL DECREASE IN WESTERN WYOMING AND CHANCES OF
SNOW WILL DEVELOP ACROSS AREAS EAST OF THE DIVIDE. THIS SHORTWAVE
WILL CAUSE WINDS TO INCREASE ONCE AGAIN ALONG THE SOUTHERN WIND
CORRIDOR AND ALONG THE EAST SLOPE OF THE DIVIDE.

.LONG TERM...TUESDAY THROUGH SATURDAY

TUESDAY AND WEDNESDAY...NORTHWEST FLOW WITH EMBEDDED SHORTWAVES WILL
KEEP CHANCES OF SNOW WESTERN/NORTHERN MOUNTAINS AND FAR WEST
VALLEYS.  DRY WITH BREEZY TO WINDY AREAS CENTRAL AND SOUTH.

THURSDAY THROUGH SATURDAY...UPPER RIDGE BUILDS OVER AREA.  DRY AND
UNSEASONABLY WARM MOST AREAS.  COOLER UNDER INVERSIONS OVER WESTERN
VALLEYS.

MEDIUM RANGE GLOBAL MODELS REMAIN IN GOOD AGREEMENT WITH LARGE SCALE
TRANSITION FROM ZONAL FLOW TO A HIGH AMPLITUDE PATTERN WITH RIDGE
BUILDING OVER THE WESTERN U.S. LATE IN THE WEEK.  DISCREPANCIES
REMAIN WITH TIMING OF PACIFIC SHORTWAVES BEFOREHAND.  AFTER FIRST IN
THIS SERIES OF SHORTWAVES MOVES ACROSS THE AREA MONDAY...THE NEXT
COUPLE OF SHORTWAVES SPLIT AS THEY TRANSLATE THE ROCKIES TUESDAY AND
TUESDAY NIGHT.  MOIST NW FLOW IN THIS PATTERN WILL CONTINUE TO BRING
PERIODS OF LIGHT SNOW TO THE NORTHERN AND WESTERN MOUNTAINS AND FAR
WEST VALLEYS.  GFS NOW SHOWS A STRONGER CLIPPER FOLLOWING IN NW FLOW
ON WEDNESDAY WHILE THE LATEST ECMWF IS MUCH WEAKER WITH THIS
SYSTEM...A REVERSAL FROM THEIR RESPECTIVE RUNS 24 HOURS AGO.
FORECAST KEEPS RELATIVELY HIGH POPS ACROSS THE WEST AS BOTH MODELS
INDICATE A MOIST UPGLIDE FLOW LINGERING INTO WEDNESDAY EVENING.
UPPER RIDGE AMPLIFIES OVER THE ROCKIES THURSDAY AND FRIDAY WITH
ECMWF SHOWING OMEGA BLOCK CENTERED NEAR 110W BY SATURDAY WHILE THE
GFS IS A BIT LOWER WITH HEIGHTS OVER THE ROCKIES...NOT QUITE AS
"BLOCKY".  WARM AIRMASS ALOFT AND LIGHT WINDS ON FRIDAY AND SATURDAY
WILL RESULT IN STEEP INVERSIONS OVER SNOW-COVERED WESTERN VALLEYS
WHERE TEMPERATURES HAVE BEEN ADJUSTED WELL BELOW CONSENSUS
GUIDANCE.  TEMPERATURES IN MOSTLY SNOW-FREE CENTRAL BASINS WILL RUN
AROUND 10 DEGREES ABOVE SEASONAL NORMALS.

&&

.AVIATION.../18Z ISSUANCE/

SOME LINGERING SNOWFALL WILL BE PRESENT ACROSS NORTHWESTERN
WYOMING THROUGH THE FORECAST PERIOD...THOUGH SNOWFALL IS EXPECTED
TO BE PRIMARILY CONFINED TO THE MOUNTAINS. WIDESPREAD VFR
CONDITIONS ACROSS THE AREA THROUGH THE FORECAST PERIOD. GUSTY WIND
IS EXPECTED KCOD...KCPR...KRKS TODAY...AND KRIW MAY ALSO SEE SOME
PERIODS OF INCREASED WIND. WIND OVER THE EASTERN SLOPES OF THE
ABSAROKA MOUNTAINS WILL INCREASE AGAIN OVERNIGHT...BRINGING LLWS
OVER KCOD AFTER 08Z. THIS LLWS MAY PERSIST THROUGH THE MORNING
HOURS BEFORE BEGINNING TO WEAKEN.

&&

.FIRE WEATHER...

VERY WINDY CONDITIONS CAN BE EXPECTED ACROSS THE ABSAROKA
MOUNTAINS AND ALONG THE ADJACENT CODY FOOTHILLS THIS MORNING.
THESE SAME AREAS WILL LIKELY SEE ANOTHER EPISODE OF VERY STRONG
WINDS LATE TONIGHT AND SUNDAY MORNING. SOUTHWEST WINDS ARE ALSO
EXPECTED TO INCREASE ACROSS THE SOUTHERN WIND CORRIDOR FROM THE
RED DESERT TO CPR THROUGH THE WEEKEND. A PACIFIC TROUGH WILL
DELIVER ACCUMULATING SNOWFALL TO WESTERN WYOMING MAINLY SUNDAY
NIGHT AND MONDAY WITH SOME SNOWFALL SPILLING EAST OVER THE DIVIDE
MONDAY NIGHT. WINDS WILL INCREASE ONCE AGAIN IN MANY AREAS WITH
THE PASSAGE OF THIS TROUGH. TEMPERATURES WILL START OUT COOL TODAY
BUT NOT COLD FOR THIS TIME OF YEAR. EXPECT MODERATING TEMPERATURES
THROUGH EARLY NEXT WEEK.
