AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
405 PM MDT SUN MAR 20 2016

.SHORT TERM...TONIGHT THROUGH MONDAY NIGHT

THE QUIET WEEKEND WEATHER IS COMING TO A SCREECHING HALT AS OUR
WRN U.S. RIDGE QUICKLY WEAKENS ALLOWING OUR ERN PACIFIC STORM
SYSTEM TO MOVE INTO THE INTERMOUNTAIN WEST. ONE MORE QUIET PERIOD
TONIGHT WITH JUST A SLIGHT CHANCE OF A WEAK RIPPLE BRUSHING BY THE
NW MTNS BEFORE 12Z. OTHERWISE...DRY WITH BREEZY TO WINDY AREAS
OVERNIGHT IN THE MTNS...EAST SLOPE FOOTHILLS AND WIND CORRIDOR.
WEAK FRONTAL BOUNDARY EDGES INTO THE NW WITH THIS WEAK WAVE AND
THEN SLOWLY TRANSLATES S AND EWD INTO MONDAY BUT VERY SHALLOW IN
NATURE. ODDS OF AT LEAST LIGHT MAINLY MTN PCPN INCREASES IN THE NW
DURING THE DAY MONDAY BUT WE REMAIN ON THE ANTICYCLONIC SIDE OF
THE JET AND THE UPPER TROUGH SUPPORT DOESN'T ARRIVE UNTIL LATER IN
THE AFTERNOON OR EARLY EVENING. GFS IS QUICKER HERE THAN THE NAM
BY 3-6 HOURS. WILL INCREASE POPS GRADUALLY DURING THE DAY BUT HOLD
OFF UNTIL MONDAY EVENING FOR THE SIGNIFICANT PCPN. ANY PCPN DURING
THE DAYTIME MONDAY SHOULD REMAIN IN THE LIQUID FORM IN THE FAR WRN
VALLEYS WITH SNOW ABOVE 7-8K. THAT CHANGES QUICKLY TUESDAY EVENING
AS THE TROUGH APPROACHES WITH INCREASING QG FORCING...JUST SAGS
SWD ENOUGH TO PROVIDE LEFT EXIT REGION DIVERGENCE AND H8-7
CONVERGENCE WILL HELP FOCUS PCPN ALONG WEST CENTRAL
AREAS...SPECIFICALLY FROM THE SRN END OF THE TETONS/JACKSON VALLEY
TO THE STAR VALLEY. FEELING RIGHT NOW IS THE STAR VALLEY AND
ADJACENT FOOTHILLS WILL BE THE HARDEST HIT AND RAIN WILL QUICKLY
CHANGE OVER TO SNOW MON EVENING WITH THE CONVECTIVE IN NATURE PCPN
WITH EVEN ISOLD THUNDER POSSIBLE. SNOW WILL CONTINUE THROUGH
MONDAY NIGHT AFTER IT CHANGES OVER. A WINTER STORM WATCH WILL
BEGIN AT 9 PM IN THE STAR VALLEY MONDAY AND CONTINUE THROUGH
TUESDAY EVENING. EAST OF THE DIVIDE...IT WILL BE WINDY IN THE WIND
CORRIDOR AND CODY FOOTHILLS MONDAY. FRONTAL BOUNDARY WILL SAG INTO
CENTRAL WYO LATE MONDAY NIGHT AND THAT COMBINED WITH THE JET
SAGGING SWD MAY AID IN A SWATH OF PCPN MOVING FROM THE I80/RED
DESERT AREA TOWARDS THE GREEN MTNS AND POSSIBLY AS FAR EAST AS
CPR. SCT RAIN/SNOW SHOWERS WILL REMAIN IN THE FCST FOR THIS
POSSIBILITY.

.MEDIUM RANGE...TUESDAY THROUGH WEDNESDAY

BY TUESDAY MORNING...THE ISOTHERMAL RIBBON/JET STREAK WILL BE
SHIFTING FROM NW TO SE WITH THE LEADING EDGE OF THE RESULTANT BAND
OF RAIN SHOWERS AND HIGH ELEVATIONS SNOW SHOWERS MOVING SOUTHEAST
ACROSS SWEETWATER COUNTY DURING THE LATE MORNING HOURS DURING
WHICH TIME PRECIP WILL MAKE ITS WAY EAST OF THE DIVIDE TO THE
NORTH. ONCE THE JET STREAK SHIFTS TO OUR SOUTH WE WILL BE UNDERTHE
LEFT FRONT QUAD OF THE JET. IN ADDITION...ENHANCED LIFT FROM THE
MID LEVEL CIRCULATION FORMING AROUND WASHAKIE NEEDLES IN THE OWL
CREEKS TRACKING SE TO ROUGHLY GAS HILLS PER GFS WILL ENHANCE LIFT
TUE. THE NATURE OF MUCH OF THE PRECIP TUESDAY WILL LIKELY START
OUT AS CONVECTIVE ELEMENTS AND THEN STRATIFORM OUT INTO LARGER
PRECIP ELEMENTS. IT IS NOT OUT OF THE QUESTION THAT PERHAPS LOCAL
AREAS COULD SEE UP TO ONE QUARTER TO ONE HALF INCH OF PRECIP FROM
THIS MID LEVEL FEATURE...BUT THAT FAR OUT IS IS UNREALISTIC TO PIN
THAT DOWN IN THE GRIDS. SUCH SEEMS TO BE THE NATURE OF PRECIP NEAR
MID LEVEL CIRCULATIONS THIS TIME OF THE YEAR.

SIGNIFICANT SNOWFALL WILL STILL BE ON GOING TUESDAY IN THE FAR
WEST WITH THE WINTER STORM WATCH FOR THE STAR VALLEY IN EFFECT
THROUGH 06Z TUE AS THAT AREA WILL BE UNDER FAVORABLE NW FLOW BY
LATE TUE IN ADDITION TO THE  DYNAMICS...AS WELL AS THE UPPER LOW
OVER SW WY BY TUE EVE PER GFS. THE EURO IS ABOUT 6 HOURS SLOWER
AND A BIT FARTHER SOUTH IN PLACEMENT WITH THESE FEATURES...BUT NOT
VERY FAR OFF. SNOW ADV AMTNS EXPECTED OVER MOST OF THE REST OF THE
WEST THROUGH TUE EVE.

OTHERWISE SNOW LEVELS WILL DROP FROM AROUND 7K TO 6K FROM NW TO
SE THROUGHOUT THE COURSE OF THE DAY TUESDAY. THE HIGHER
ELEVATIONS OF THE  REGION OF SW WY INCLUDING SWEETWATER COUNTY AS
WELL AS THE GREEN MTNS COULD SEE LOCALLY 2 TO 4 INCHES...OTHERWISE
1 TO 3 INCHES BY LATE TUESDAY. THE CENTRAL BASINS EAST OF THE
DIVIDE WILL LIKELY SEE AROUND 1 TO 2 INCHES BY LATE TUE EVE.

WITH THE SFC LEE SIDE TROUGH ALREADY IN PLACE...STRONG
CYCLOGENESIS WILL TAKE PLACE IN EASTERN SO TUE NT. THIS MEANS AN
INCREASE IN SNOWFALL IN OUR EASTERN ZONES...NAMELY NATRONA AND
JOHNSON COUNTIES...AS WELL AS OVER THE BIG HORN MTNS WHERE SNOW
AMTNS CONDUCIVE FOR ADV/WARNINGS ARE IN PLACE IN THE GRIDS FOR TUE
NT/WED FOR NOW. RESULTANT CYCLONIC NORTH WINDS WILL BE VERY
FAVORABLE FOR UPSLOPE SNOW IN CPR/CPR MTN WHERE 14 INCHES OF SNOW
IS SLATED TO OCCUR ON CPR MTN. IN ADDITION...A NARROW AREA OF
WRAP AROUND ISENTROPIC LIFT WILL HELP TO ENHANCE THE SNOWFALL IN
THESE AREAS. WITH THE STORM BOMBING OUT...WE SHOULD SEE NORTH
WINDS INCREASING TO 20 TO 30 MPH WITH GUSTS OF 40 TO 50 MPH
THROUGH THE WIND RIVER CANYON AND ADJACENT NORTHERN WIND RIVER
BASIN TUE EVE.

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY

BRIEF BREAK IN BETWEEN SYSTEMS WEDNESDAY NIGHT AND THURSDAY EXCEPT
FOR A CHANCE OF SNOW IN THE NW MTNS. NEXT COLD TROUGH IS STILL
POISED TO DROP SOUTH ACROSS THE AREA THURSDAY NIGHT INTO FRIDAY
WITH A GOOD CHANCE OF SNOW AND QUITE COLD LATE MARCH TEMPS. THIS
WILL PREVAIL THROUGH AT LEAST FRIDAY NIGHT BEFORE GRADUAL CLEARING
ON SATURDAY BUT QUITE COLD. SLOW IMPROVEMENT INTO SUNDAY BUT THERE
COULD BE A GLANCING BLOW SHORTWAVE IN THE NERN ZONES AROUND
SATURDAY NIGHT. MORE ON THIS TOMORROW AS A LOT IS GOING ON IN THE
SHORT TERM.

.AVIATION.../00Z ISSUANCE/

WEST OF THE CONTINENTAL DIVIDE...KJAC/KRKS/KPNA/KBPI ROUTES

VFR CONDITIONS TO PREVAIL THROUGH TONIGHT. ISOLATED SNOW SHOWERS
MAY DEVELOP IN THE FAR WEST MOUNTAINS AFTER 08Z MONDAY. CONDITIONS
WILL BEGIN TO DETERIORATE ON MONDAY WITH AN INCREASING CHANCE OF
VALLEY RAIN AND MOUNTAIN SNOW SHOWERS...MAINLY IN THE NORTHWEST
MOUNTAINS. MOST AREAS WILL REMAIN VFR DURING THE DAY EXCEPT FOR
LOWERING CIGS AROUND THE TETONS. ISOLATED THUNDERSTORMS ARE ALSO
POSSIBLE IN THE FAR WEST MONDAY AFTERNOON.

EAST OF THE CONTINENTAL DIVIDE...KCPR/KCOD/KRIW/KWRL/KLND ROUTES

VFR CONDITIONS WILL CONTINUE THROUGH MONDAY AFTERNOON. IT WILL
REMAIN WINDY AT TIMES FROM JEFFREY CITY TO KCPR THROUGH MONDAY

.FIRE WEATHER...

...FIRE WEATHER WATCH FOR ZONES 276...280...281 AND 287 FROM 11 AM
TO 8 PM MONDAY...

A VERY DRY AIRMASS WILL COMBINE WITH WINDY CONDITIONS AND WARMER
TEMPERATURES ON MONDAY TO POTENTIALLY CREATE FIRE WEATHER
CONCERNS OVER PARTS OF CENTRAL WYOMING. TEMPERATURES WELL INTO
THE 60S ALONG WITH WEST TO SOUTHWEST WIND 20 TO 30 MPH WITH GUSTS
OVER 40 MPH ALONG WITH MINIMUM RH'S AS LOW AS 10 TO 15 PERCENT.
OTHER AREAS OF CENTRAL WYOMING NOT IN THE FIRE WEATHER WATCH WILL
ALSO BE WARM AND DRY WITH ELEVATED FIRE CONCERNS. CONDITIONS WILL
IMPROVE DRAMATICALLY TUESDAY INTO WEDNESDAY AS A COLD STORM SYSTEM
SPREAD RAIN CHANGING TO SNOW ACROSS THE AREA.

THE WEST WILL SEE A STORM SYSTEM SPREAD A CHANCE OF SHOWERS IN AS
THE DAY WEARS ON WITH SNOW MONDAY NIGHT AND TUESDAY FOR LOW FIRE
CONCERNS.
