.PREV DISCUSSION... /ISSUED 444 PM MDT SAT MAR 28 2009/

SHORT TERM...TONIGHT THROUGH TUESDAY
SOME SNOW IN THE HIGHER ELEVATIONS OF THE WESTERN MTS THIS PM
WITH THE UPGLIDE CONTINUING THERE. PTCLDY SKY OVER THE REST OF THE
REGION. BREEZY AREAS AND MILD TEMPS FOR THE MOST PART. MAIN
WEATHER STORY WILL BE THE INCOMING TROUGH WHICH WILL IMPACT THE
WEST TONIGHT AND SUNDAY. HAVE ISSUED ADVISORIES FOR MANY PLACES AS
CONDITIONS LOOK GOOD FOR SNOW THROUGH SUNDAY AFTERNOON. CONVECTIVE
SNOW SHOWERS MAY ALSO PLAY A ROLE IN LOCALLY HEAVY AMOUNTS.
CENTRAL AND EAST CENTRAL WY WILL SEE CONVECTIVE ACTIVITY SUNDAY
AFTERNOON AS THE COLD FRONT APPROACHES. HAVE ADDED ISOLATED STORMS
TO THE SOUTH AND CENTRAL ZONES. IT WILL BE BREEZY TO WINDY AHEAD
OF THE COLD FRONT AND MILD IN THE CENTRAL AND EAST CENTRAL. BRISK
WIND WILL ALSO OCCUR BEHIND THE COLD FRONT OUT WEST AND IN THE
NORTH. THE TRACK OF THE STORM CONTINUES TO BE THROUGH CENTRAL WY
SUNDAY NIGHT AND INTO EASTERN WY BY 12Z MONDAY PER THE GFS/NAM/EC.
THIS WOULD BRING THE BEST SNOW POTENTIAL TO THE NORTH ZONES SUNDAY
NIGHT AND MONDAY. HAVE ADDED A FEW AREAS TO THE WATCH BASED ON THE
TRACK. SOME SNOW STILL EXPECTED FROM LANDER TO CASPER LATE SUNDAY
NIGHT AND MONDAY AS THE STORM INTENSIFIES OVER FAR EAST WY. HAVE
ADJUSTED SNOW AMOUNTS A LITTLE IN THE NORTH AND CENTRAL AND WILL
SEE HOW THINGS LOOK LATER. THE SNOW TAPERS OFF TO SNOW SHOWERS IN
THE WEST MONDAY. SNOW TAPERS OFF AND ENDS IN THE CENTRAL AND EAST
CENTRAL MONDAY NIGHT AS THE STORM DEPARTS. ON TUESDAY THE NEXT
WEATHER SYSTEM WILL SPREAD SNOW INTO THE WESTERN MOUNTAINS. MOSTLY
DRY ELSEWHERE ON TUESDAY. COLD HIGHS MONDAY WITH WARMER HIGHS ON
TUE.

LONG TERM...TUESDAY NIGHT THROUGH SATURDAY
MODEL DIFFERENCES CONTINUE FOR WEDNESDAY SYSTEM. THE GFS IS
STRONGER WITH THE SHORTWAVE THAT RIDES DOWN IN THE STRONG NW FLOW
BUT BOTH MODELS SHOW PLENTY OF MOUNTAIN SNOWFALL AND PCPN ACROSS
AT LEAST THE NRN ZONES. THE GFS WOULD WARRANT HIGHER POPS FURTHER
SOUTH WITH ITS DIGGING SHORTWAVE AXIS PASSING RIGHT THROUGH THE
AREA WED MORNING. LIKELY PRECIP SPREADING TO ALL OF THE WEST AND
NORTH TUESDAY NIGHT AND WEDNESDAY WITH CHANCE POPS ELSEWHERE.
STRONG 150KT JET MAY ALSO PROVIDE SOME LEFT EXIT OR CURVED NOSE
JET STREAK DIVERGENCE TUESDAY NIGHT ALONG WITH MODERATE QG AND
FRONTAL FORCING. BRISK NW FLOW PREVAILS WEDNESDAY NIGHT AND
THURSDAY WITH ISENTROPIC UPGLIDE AND AT LEAST CHANCE POPS
WARRANTED ACROSS THE MTNS. THE NRN ZONES MAY ALSO SEE SOME LIGHT
RAIN OR SNOW IN THIS PATTERN. NEXT TROUGH BEGINS TO SLOWLY DIG
INTO THE CENTRAL ROCKIES OVER EVEN NRN GREAT BASIN. THE ECMWF IS
FURTHER SW WITH THE TROUGH DEVELOPMENT OVER UTAH WHILE THE
OPERATIONAL GFS HAS THE ELONGATED TROUGH DIGGING THROUGH WYOMING
AND DOWN INTO NRN UT BY FRIDAY EVENING. WILL SHOW INCREASING POPS
FROM WEST TO EAST FRIDAY INTO FRIDAY NIGHT AND CONTINUING INTO
SATURDAY BEFORE GRADUALLY SHIFTING TO THE SERN ZONES SATURDAY
NIGHT. LEANED MORE TOWARDS THE ECMWF ON SATURDAY AND SATURDAY
NIGHT. TEMPERATURES WILL BE A LITTLE TRICKY WITH RAPID TRANSITION
FROM ONE SYSTEM TO THE NEXT. GFS IS COLDER THROUGHOUT WHILE THE
ECMWF HAS A COUPLE WARMER DAYS IN BETWEEN STORMS. FORECAST IS A
COMPROMISE EARLY ON AND THEN LEANING TOWARD THE ECMWF BY THE END
OF THE PERIOD.

AVIATION...
ANOTHER EARLY SPRING SNOWSTORM NOW OFF THE PACIFIC NORTHWEST COAST
WILL BE TRACKING EAST SOUTHEAST TO CENTRAL WYOMING THROUGH SUNDAY
NIGHT. AHEAD OF THIS WEATHER FEATURE...CIGS AND VSBY WILL
DETERIORATE EARLY THIS EVENING AS SNOWFALL AND SOME BLOWING SNOW
INCREASES CAUSING WIDESPREAD IFR AND LIFR CONDITIONS ACROSS FAR
WESTERN WY TONIGHT AND CONTINUING THROUGH SUNDAY. KJAC CAN EXPECT
THESE IFR CONDITIONS FOR MOST OF TONIGHT AND SUNDAY WITH THESE
CONDITIONS ARRIVING AT KPNA BY MIDNIGHT TONIGHT WITH MAINLY MVFR
CONDITIONS AT KBPI. SOUTH AND SOUTHWEST WINDS OF 15 TO 30 MPH WILL
CAUSE CONSIDERABLE BLOWING SNOW IN WESTERN WYOMING TONIGHT AND
SUNDAY. AS THE WEATHER SYSTEM TRACKS ACROSS CENTRAL WYOMING...THE
PRECIP WILL BEGIN TO SPILL OVER TO AREAS EAST OF THE CONTINENTAL
DIVIDE IN NORTHERN WY BY 22Z INCLUDING KCOD WITH MVFR CONDITIONS
JUST BEGINNING THERE BY 00Z MONDAY. SOUTHWEST WINDS OF 25 TO 35 MPH
