WEAK HIGH PRESSURE ALOFT WILL BE OVER WESTERN AND CENTRAL WYOMING

SOLUTION WHERE SHORTWAVE COMING THROUGH SAT/SUN WOULD DIG TO
TEXAS/OKLAHOMA BY MONDAY. THE GFS SOLUTION IS MUCH FASTER AND LESS
AMPLIFIED WITH ENERGY PROGRESSING INTO THE MIDWEST. TEND TO FAVOR A
SOLUTION ALIGNED MORE WITH 12Z/GEM AND 00Z/ECMWF ALBEIT ONE NOT
QUITE AS AMPLIFIED. DETAILS WILL BE DIFFICULT TO TIME AND WILL USE
MORE OF A BROAD BRUSH APPROACH WITH SNOW CHANCE REMAINING HIGH IN THE
WEST FRIDAY NIGHT AND SATURDAY. MAY STILL NEED TO BOOST SNOW CHANCES
SATURDAY NIGHT AND SUNDAY DEPENDING UPON THE EVOLUTION OF THE TROUGH
THIS WEEKEND. TEMPERED SOLUTION WOULD STILL OFFER DRY RIDGING ACROSS
WYOMING LATER SUNDAY AND MONDAY. SNOW CHANCES HAVE BEEN LOWERED
ACCORDINGLY FOR THOSE TWO DAYS. COULD BE ENOUGH MOISTURE ROUNDING
THE RIDGE BY TUESDAY TO GENERATE AT LEAST LOW SNOW CHANCE BY THAT
TIME OVER THE NORTHWEST AND BIGHORN MOUNTAINS. AFTER SEVERAL MILD
DAYS TO END THE WEEK...AT LEAST EAST OF THE DIVIDE...PACIFIC COLD
FRONT WILL USHER IN COOLER AIR FOR THE WEEKEND. ECMWF SOLUTION KEEPS
THINGS VERY COLD SUNDAY AND MONDAY IN NORTHERLY FLOW WITH 700MB
TEMPERATURES AROUND -20C. OTHER MODEL SOLUTIONS HAVE SIGNIFICANTLY
WARMER 700MB TEMPERATURES AROUND ZERO TO -5C. AGAIN...HIGHLY
AMPLIFIED ECMWF SOLUTION SEEMS TOO STRONG AND HAVE GENERALLY KEPT
HIGH TEMPERATURES FAIRLY CLOSE TO CLIMATOLOGICAL NORMALS. ONE LAST
BREEZY/WINDY DAY ON SATURDAY BEFORE RIDGING LIMITS WIND FOR THE
REMAINDER OF THE EXTENDED PERIOD.

.AVIATION.../00Z ISSUANCE/

CONDITIONS WILL REMAIN VFR THROUGH THE OVERNIGHT HOURS AT ALL
TERMINALS IN ADVANCE OF THE FIRST IN A SERIES OF SHORTWAVES EMBEDDED
IN PROGRESSIVE ZONAL FLOW. THIS SHORTWAVE REACHES WESTERN WYOMING BY
12Z AND SHOULD BEGIN IMPACTING KJAC BETWEEN 12Z-15Z/WEDNESDAY.
CONDITIONS WILL GRADUALLY DETERIORATE DURING THE MORNING AT KJAC
WITH MVFR POSSIBLE BY 18Z/WEDNESDAY. SNOW WILL BE ONGOING BY
MID-AFTERNOON WEDNESDAY AT KJAC AND FOR NOW HAVE INDICATED MVFR
CEILINGS/VISIBILITY. HOWEVER...IFR A DISTINCT POSSIBILITY DURING THE
LATE AFTERNOON AS OROGRAPHIC MACHINE CRANKS UP. MOISTURE FETCH AND
FAVORABLE MID-LEVEL FLOW WILL KEEP SNOW IN THE KJAC FORECAST THROUGH
WEDNESDAY NIGHT. MOUNTAIN TOP OBSCURATIONS WILL BECOME WIDESPREAD
OVER THE WESTERN MOUNTAINS BETWEEN 09Z-15Z/WEDNESDAY. THE TETONS AND
OTHER NEARBY RANGES WILL BE COMPLETELY OBSCURED BY MIDDAY WEDNESDAY.
HAVE TRENDED KBPI AND KPNA TOWARD LOWERING VFR CEILINGS AND VCSH
WEDNESDAY BUT FOR NOW BELIEVE WIDESPREAD SNOW WILL WAIT UNTIL AFTER
00Z/THURSDAY AT THOSE TERMINALS. TERMINALS EAST OF THE DIVIDE WILL
REMAIN VFR THROUGH WEDNESDAY WITH ONLY MID-HIGH CLOUD DECKS IN
DOWNSLOPE FLOW. SURFACE PRESSURE GRADIENT STRENGTHENS AND 700MB
WINDS INCREASE WEDNESDAY MORNING ACROSS CENTRAL WYOMING. THIS WILL
LEAD TO SOUTHWEST WIND OF 25-45KTS AT KCPR AND ACROSS THE CENTRAL
WYOMING MOUNTAINS. LIKELY TO BE SOME TURBULENCE BY WEDNESDAY MORNING
IN THE LEE OF THE GREEN MOUNTAINS. SIMILAR TO LAST NIGHT...SUSPECT
THAT WIND AT KCOD WILL INCREASE BEFORE 12Z/WEDNESDAY AND PERSIST
THROUGH THE MORNING BEFORE DECREASING. HAVE ALSO BEGUN TO HINT AT
WESTERLY SURFACE WIND LATE WEDNESDAY AFTERNOON AT KLND AND KRIW AS
MIXING COULD OCCUR BY LATE IN THE DAY.

.FIRE WEATHER...

WEAK HIGH PRESSURE ALOFT WILL BE OVER WESTERN AND CENTRAL WYOMING
TONIGHT WITH WESTERLY FLOW ALOFT PRODUCING AREAS OF BRISK WINDS
ALONG AND NEAR THE EAST SLOPES OF THE MOUNTAINS AND THROUGH THE
WIND CORRIDOR. THE WINDS WILL KEEP THE AIR MIXED IN THE VALLEYS
AND BASINS WITH WARMER TEMPERATURES THROUGH THE NIGHT.  A PACIFIC
STORM SYSTEM WILL MOVE INLAND WITH THE LEADING EDGE OF SNOWFALL
MOVING INTO THE WESTERN MOUNTAINS OF WYOMING WEDNESDAY MORNING.
THE SNOWFALL WILL INCREASE AND BECOME WIDESPREAD OVER THE WEST
THROUGH THE DAY. THE EAST SLOPES OF THE MOUNTAINS AND WIND
CORRIDOR SHOULD SEE HIGH WINDS DEVELOP. SNOWFALL AND WIND WILL
CONTINUE WEDNESDAY NIGHT INTO THURSDAY. WINTER STORM WATCHES AND
HIGH WIND WATCHES REMAIN IN EFFECT. PLEASE REFER TO THESE PRODUCTS
FOR MORE SPECIFIC DETAIL ON THE DEVELOPING STORM.
