.UPDATE...

MINOR UPDATE TO ADJUST CLOUDS/WINDS TO FIT CURRENT AND EXPECTED
CONDITIONS REST OF TONIGHT.

.SHORT TERM...(LATE THIS AFTERNOON THROUGH MONDAY NIGHT) ISSUED AT
305 PM MST SAT JAN 3 2015

EARLY AFTERNOON WATER VAPOR IMAGERY LOOP SHOWED THE POTENT SHORTWAVE
MOVING EAST ACROSS SOUTHEAST WY AND WESTERN NE. ASSOCIATED ARCTIC
COLD FRONT SURGED THROUGH THE CWFA THIS MORNING...BRINGING BLUSTERY
NORTH WINDS...SNOW AND BLOWING SNOW AND VERY COLD TEMPERATURES. WIND
CHILL TEMPERATURES HAVE FALLEN INTO THE TEENS BELOW ZERO. REGIONAL
RADAR LOOP INDICATED THE WESTERN EDGE OF THE SNOW ALONG A SARATOGA
TO LUSK LINE AND MOVING SOUTHEAST. CLOUD TOPS PER IR SATELLITE
HAVE BEEN SLOWLY WARMING...INDICATIVE OF A DECREASING TREND IN
SNOW INTENSITY. THE GUSTY WINDS WILL PERSIST THROUGH LATE AFTERNOON
BEFORE DECREASING THIS EVENING...SO BLOWING SNOW WILL CONTINUE TO
CREATE HAZARDOUS TRAVEL. THEREFORE...EXTENDED THE WINTER WEATHER
ADVISORY UNTIL 6 PM MST.

SHORTWAVE RESPONSIBLE FOR THE SNOW AND WINDY CONDITIONS WILL QUICKLY
EXIT EAST OF THE CWFA THIS EVENING WITH DECREASING WINDS. ATTENTION
WILL TURN TO THE DEVELOPMENT OF VERY STRONG WESTERLY WINDS ACROSS
THE WIND CORRIDORS OF SOUTHEAST WY BEGINNING SUNDAY MORNING AND
CONTINUING THROUGH MONDAY NIGHT. MODELS PROG 120+ KT 250MB JET
TRANSLATING SOUTHEAST ACROSS WY SUNDAY THROUGH MONDAY. THE CRAIG-
CASPER 700MB HEIGHT GRADIENT INCREASES FROM 61 MTRS AT 15Z SUNDAY
TO 94 MTRS AT 18Z MONDAY. MEANWHILE...THE 850MB GRADIENT RISES
ABOVE 70 MTRS AT 09Z MONDAY... PEAKING AT 102 MTRS AT 18Z MONDAY.
SUSTAINED WESTERLY WINDS OF 30-40 KT WITH GUSTS TO 55 KT SUNDAY
WILL INCREASE TO 40-50 KT WITH GUSTS TO 70 KT SUNDAY NIGHT AND
MONDAY. MOST SUSCEPTIBLE LOCATIONS AFFECTED BY THESE HIGH WINDS
WILL INCLUDE BORDEAUX...I-80 SUMMIT AND ARLINGTON. THE HIGH WINDS
WILL PERSIST THROUGH LATE MONDAY NIGHT. HAVE UPGRADED THE HIGH
WIND WATCH TO A WARNING THIS AFTERNOON.

SNOW WILL END EARLY THIS EVENING FOR LOWER ELEVATIONS...BUT
CONTINUE FOR THE SNOWY AND SIERRA MADRES. IN FACT...A PROLONGED
PERIOD OF OROGRAPHIC SNOW WILL LIKELY OCCUR FOR ELEVATIONS ABOVE
8000 FEET. SNOW WILL BE MODERATE TO HEAVY AT TIMES WITH ACCUMULATIONS
THROUGH MONDAY NIGHT RANGING FROM 10 TO 18 INCHES OVER THE SNOWY
AND SIERRA MADRES...TO 4 TO 6 INCHES FOR THE SURROUNDING VALLEYS.
A WEAK DISTURBANCE WILL MOVE SOUTHEAST ACROSS EASTERN WY AND
NORTHERN NE MONDAY PRODUCING LIGHT SNOW.

LOW TEMPERATURES TONIGHT WILL BOTTOM OUT FROM -5 TO -15 DEGREES
EAST OF THE LARAMIE RANGE...WITH -5 TO -10 FOR THE LARAMIE VALLEY.
ELSEWHERE...LOWS WILL BE IN THE SINGLE DIGITS ABOVE ZERO. A
MODERATION IN TEMPERATURES WILL COMMENCE SUNDAY WITH HIGHS IN THE
TEENS AND 20S. NOT AS COLD SUNDAY NIGHT WITH LOWS FROM 0 TO -5
DEGREES OVER THE PLAINS...TO TEENS AND LOWER 20S ALONG AND WEST
OF THE LARAMIE RANGE. MUCH MILDER MONDAY WITH GUSTY DOWNSLOPE
WINDS RESULTING IN HIGH TEMPERATURES IN THE 30S TO LOWER 40S.
MILDER MONDAY NIGHT WITH LOWS IN THE TEENS AND 20S.

.LONG TERM...(TUESDAY THROUGH SATURDAY)
ISSUED AT 205 PM MST SAT JAN 3 2015

THE GENERAL STORM TRACK SHOULD REMAIN TO OUR NORTH AND EAST FOR THE
FIRST HALF OF THE EXTENDED PERIOD. WHILE NO MAJOR STORMS APPEAR TO
BE ON THE HORIZON...MEDIUM RANGE MODELS ARE IN GOOD AGREEMENT WITH
FAST NORTHWEST FLOW ALOFT KEEPING THINGS ON THE COOL SIDE WITH GFS
H7 TEMPS REMAINING BELOW -10 DEG C ACROSS THE NORTHERN ZONES THROUGH
ABOUT MIDWEEK. BREEZY CONDITIONS MAY CARRY OVER INTO TUE AFTERNOON
AFTER A VERY WINDY DAY ON MON...BUT THE STRONGEST FLOW ALOFT APPEARS
TO SHIFT EASTWARD INTO CENTRAL SD/NE WHICH SHOULD KEEP GUSTS AT OR
BELOW 50 MPH IN THE WESTERN PANHANDLE. THE MODELS SUGGEST LINGERING
MID LEVEL ENERGY TO THE SOUTH OF A CYCLONIC 150+ KT H25 JET OVER
THE NORTHERN PLAINS AT 18Z TUE. THINKING THERE WILL BE ENOUGH
MOISTURE TO SQUEEZE OUT AT LEAST A FEW SNOW SHOWERS...SO ADDED
LOW END POPS ACROSS THE NORTH AND EAST FOR TUE/TUE NIGHT WITH
MODEST INSTABILITY OWING TO COLD/CYCLONIC FLOW ALOFT. A WARMING
TREND IS STILL PROBABLE ON THU WITH DOWNSLOPING AND H7 TEMPS
POTENTIALLY CLIMBING AS HIGH AS 5 DEG C BY MID AFTERNOON BENEATH A
TRANSITORY RIDGE. HARD TO SAY HOW WARM IT WILL GET AT THIS POINT
AS WE WILL PROBABLY HAVE ADDITIONAL SNOW ACCUMULATIONS BETWEEN NOW
AND THEN WHICH SHOULD CUT BACK ON OUR OBSERVED HIGHS.
REGARDLESS...THE LATEST MEX SHOWS A HIGH OF 54 F FOR CHEYENNE
WHICH SUGGESTS A BRIEF TRANSITION TO SOME NICER HIGHS PRIOR TO THE
NEXT FROPA. THAT FROPA ARRIVES FRI...FORCING HIGHS BACK INTO THE
20S AND 30S WITH INCREASING CHANCES FOR PRECIPITATION.

TO SHIFT EASTWARD INTO CENTRAL SD/NE WHICH SHOULD KEEP GUSTS AT OR
BELOW 50 MPH IN THE WESTERN PANHANDLE. THE MODELS SUGGEST LINGERING
MID LEVEL ENERGY TO THE SOUTH OF A CYCLONIC 150+ KT H25 JET OVER
THE NORTHERN PLAINS AT 18Z TUE. THINKING THERE WILL BE ENOUGH
MOISTURE TO SQUEEZE OUT AT LEAST A FEW SNOW SHOWERS...SO ADDED
LOW END POPS ACROSS THE NORTH AND EAST FOR TUE/TUE NIGHT WITH
MODEST INSTABILITY OWING TO COLD/CYCLONIC FLOW ALOFT. A WARMING
TREND IS STILL PROBABLE ON THU WITH DOWNSLOPING AND H7 TEMPS
POTENTIALLY CLIMBING AS HIGH AS 5 DEG C BY MID AFTERNOON BENEATH A
TRANSITORY RIDGE. HARD TO SAY HOW WARM IT WILL GET AT THIS POINT
AS WE WILL PROBABLY HAVE ADDITIONAL SNOW ACCUMULATIONS BETWEEN NOW
AND THEN WHICH SHOULD CUT BACK ON OUR OBSERVED HIGHS.
REGARDLESS...THE LATEST MEX SHOWS A HIGH OF 54 F FOR CHEYENNE
WHICH SUGGESTS A BRIEF TRANSITION TO SOME NICER HIGHS PRIOR TO THE
NEXT FROPA. THAT FROPA ARRIVES FRI...FORCING HIGHS BACK INTO THE
20S AND 30S WITH INCREASING CHANCES FOR PRECIPITATION.
