STREAK OVER IDAHO AND NORTHEAST UTAH CURRENTLY NOT PRODUCING MUCH
MORE THAN AREAS OF CIRRUS AND POSSIBLY A LITTLE VIRGA WITH LOW LEVEL
MOISTURE SEVERELY LACKING. WARM AIR ADVECTION/ISENTROPIC UPGLIDE STILL
EXPECTED TO BEGIN IN EARNEST EARLY THURSDAY MORNING AHEAD OF A POWERFUL
PACIFIC UPPER LOW. BACKED OFF ON THE ONSET OF THE SNOW BY SEVERAL HOURS
IN THE WEST TONIGHT WITH LATEST MODEL DATA AGREEING WELL WITH SATELLITE
TRENDS OF A SLIGHTLY SLOWER EASTWARD MOVEMENT OF THE ASSOCIATED BAROCLINIC
LEAF AND INITIAL AREA OF UPGLIDE AND SATURATED OR NEAR SATURATED ATMOSPHERE.
SNOW ADVISORY LEVEL AMOUNTS ARE EXPECTED OVER THE WEST ON THURSDAY WITH
6 TO 10 INCH AMOUNTS COMMON IN THE MOUNTAINS WITH 3 TO 7 INCHES IN
THE STAR AND JACKSON VALLEYS. WILL LET NIGHT SHIFT TAKE ONE LAST LOOK
AT THINGS BEFORE ISSUING ANY WINTER HIGHLIGHTS...HOWEVER. STRONG JET
DYNAMICS COMBINING WITH THE ISENTROPIC UPGLIDE AND INCREASING INSTABILITY
FOR WIDESPREAD SNOW BEGINNING JUST BEFORE SUNRISE THURSDAY AND CONTINUING
THROUGH THE DAY. AS SURFACE PRESSURES FALL IN THE LEE OF COLORADO ROCKIES
THURSDAY EVENING AND SURFACE HIGH PRESSURE BUILDS INTO NORTHEAST MONTANA...SURFACE
CONVERGENCE DEVELOPS EAST OF THE DIVIDE NEAR A CASPER TO COOKE CITY
MONTANA LINE. SNOW ADVISORY MAY BE NEED TO BE EXTENDED FOR YELLOWSTONE
PARK AND THE ABSAROKA MOUNTAINS FOR THURSDAY NIGHT. AREA OF WIDESPREAD
SNOW SHIFTS EASTWARD ON FRIDAY INTO THE BIGHORN MOUNTAINS AND ADJACENT
JOHNSON COUNTY. GOOD UPSLOPE CONDITIONS FOR EASTERN BIGHORNS AND BUFFALO
AND KAYCEE AREAS EARLY FRIDAY MORNING. A WINTER STORM WATCH MAY BE NECESSARY
FOR THESE AREAS FOR EARLY FRIDAY MORNING THROUGH FRIDAY EARLY EVENING.
GOOD UPSLOPE CONDITIONS PROGGED BY 12Z GFS AND NAM12 FROM ABOUT 06Z
FRIDAY THROUGH ABOUT 03Z SATURDAY. ORIENTATION OF INVERTED SURFACE TROUGH
FRIDAY THE BIGGEST QUESTION. CURRENT PROGGED PLACEMENT WOULD KEEP
ACCUMULATING SNOW EAST OF RIVERTON AND LANDER BUT A SLIGHT
DISPLACEMENT OF THIS TROUGH TO THE WEST AND WIDESPREAD SNOW WOULD
BANK UP AGAINST THE EAST SLOPES OF THE WIND RIVER MOUNTAINS. WILL
WAIT AND SEE WHAT LATER SOLUTIONS HAVE TO OFFER BUT HAVE INCREASED
PRECIPITATION CHANCES SOMEWHAT GIVEN THAT THE COLDER MORE DENSE
AIRMASS WILL EVENTUALLY SEEP INTO THE WIND RIVER BASIN AND LANDER
FOOTHILLS FRIDAY AFTERNOON.

.LONG TERM...SATURDAY NIGHT THROUGH WEDNESDAY
DEEP TROUGH BEGINS TAKING SHAPE OVER THE SOUTHWEST THIS WEEKEND
WITH POTENTIAL MOIST AND DYNAMIC FLOW OVERRUNNING LOW LEVEL
UPSLOPE BY SUNDAY. ON SATURDAY...H5 AIR AROUND -30C IS FORECAST TO
PRODUCE VERY STEEP LAPSE RATES IN EXCESS OF 8C/KM WITH LIFTED
INDICES AT OR BELOW ZERO. WITH MOIST SW FLOW AND JET STREAK JUST
MOVING INTO THE FAR SRN BORDER AREA...IT SEEMS SNOW SHOWERS WILL
BE A DECENT POTENTIAL AS FAR N AS THE CNTRL ZONES. THE WEST SHOULD
SEE STEADY LIGHT TO MODERATE SNOW. AS THE UPPER LOW DEVELOPS OVER
THE SW ON SUNDAY...UPSLOPE IS FORECAST TO DEVELOP EAST OF THE
DIVIDE WITH POSSIBLE JET STREAK DYNAMICS. NOT WILLING TO GO LIKELY
POPS QUITE YET DUE TO VERY S POSITION OF THE UPPER LOW BUT AS LONG
AS THE SURFACE HIGH DOES INDEED DROP SOUTH ACROSS THE AREA...WE
SHOULD SEE A HIGH LIKELIHOOD OF PCPN EAST OF THE DIVIDE AT SOME
POINT SUNDAY AS DYNAMICS OVERRUN THE COLD DOME. UPPER LOW WILL
LIKELY MOVE WELL SOUTH OF THE AREA ON MONDAY WITH BETTER PCPN
CHANCES MOVING JUST SE OF OUR FORECAST AREA. POTENTIAL WEAK WAVE
BEHIND THIS SYSTEM COULD PROVIDE SOME SNOW SHOWERS MONDAY INTO
MONDAY NIGHT...ESPECIALLY IN THE HIGH COUNTRY. MOST STRONG UPPER
LOWS DO HAVE A WEAK SHORTWAVE THAT DROPS SE THE NEXT DAY AND THIS
ONE APPEARS TO BE NO DIFFERENT. FORECAST IS MORE UNCERTAIN IN THE
TUESDAY/WEDNESDAY TIMEFRAME. THE 00Z GFS RUN IS MORE BULLISH AGAIN
IN A FLAT RIDGE ISENTROPIC UPGLIDE PATTERN. WILL KEEP THE CHANCE
POPS IN THE WRN MOUNTAINS TUESDAY AND SLIGHT CHANCE FOR WEDNESDAY
FOR NOW. TEMPERATURES WILL BE COOL IN THE FIRST HALF OF THIS
PERIOD BUT SHOULD BEGIN TO WARM AS HEIGHTS BUILD INTO EARLY NEXT
WEEK. READINGS MAY VERY WELL END UP WARMER THAN CURRENT FORECAST
SIMILAR TO CURRENT READINGS BUT WILL LET LATER SHIFTS DETERMINE
THE TREND.
