FORECAST FOR BRIDGER-TETON NATIONAL FOREST AVALANCHE CENTER
NATIONAL WEATHER SERVICE RIVERTON WY
210 AM MST MON DEC 5 2016


.DISCUSSION...

A RANGE OF LIGHT TO OCCASIONALLY HEAVY SNOWFALL CONTINUES TONIGHT ON
THE NOSE OF A JET ASSOCIATED WITH AN UPPER LEVEL DISTURBANCE. THE
HEAVIEST SNOW IS NOW OCCURRING ON AN ISOLATED TO SCATTERED BASIS AS
SHOWERS UNDER THE INFLUENCE OF VERY COLD DRY AIR ALOFT NOW MOVING
OVER THE NOW SIGNIFICANTLY WARMER SURFACE...MAKING IT RELATIVELY
UNSTABLE. HOWEVER, WITH VERY COLD AND RELATIVELY DRY AIR ALREADY
ENTRAINING INTO PORTIONS OF NORTHWEST WY...HEAVIER SNOWFALL WILL
TAPER OFF QUICKLY FROM NORTH TO SOUTH ACROSS THE FORECAST AREA LATER
THIS MORNING...LEAVING AREAS OF LIGHT SNOW FLURRIES OR ICE CRYSTALS
AROUND ACROSS THE FORECAST AREA. 24 TO 30 HR TOTAL ACCUMULATION WILL
RANGE FROM 4 TO 22 INCHES OF MOUNTAIN/VALLEY SNOW BY MID
MORNING/NOON TODAY. THE TETONS AND GROS VENTRE SHOULD GENERALLY
BENEFIT THE MOST. WINDS WILL EVENTUALLY BECOME ORIENTED WEST TO
NORTHWEST AT 10 TO 30 MPH THIS MORNING BEFORE DECREASING SOME AND
BECOMING SOUTH TO SOUTHWEST ONCE AGAIN BY THIS AFTERNOON OVER THE
NORTHERN HALF OF THE FORECAST AREA. TONIGHT THE WIND WILL
CONTINUE TO DECREASE TO 5 TO 15 MPH OUT OF THE SOUTH TO
SOUTHWEST...THEN SOUTH TO EAST 5 TO 15 MPH ON TUESDAY. ACTUAL HIGH
TEMPERATURES FOR DECEMBER 5TH WERE PROBABLY ALREADY IN PLACE
SHORTLY AFTER MIDNIGHT THIS MORNING AND WILL LIKELY FALL THROUGH
THE REST OF THE DAY...WITH LOW TEMPERATURES TUESDAY MORNING
FALLING TO AS MUCH AS 25 TO 30 BELOW ZERO OVER THE HIGH MOUNTAINS
TO 5 TO 10 BELOW ZERO IN THE VALLEYS.
