NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
235 PM AKST SAT DEC 8 2012

.DISCUSSION...
AS ADVERTISED THE WEATHER PATTERN WILL BECOME MORE ACTIVE AS A
SERIES OF DISTURBANCES MOVE ACROSS ALASKA. THE FIRST SYSTEM TO
IMPACT THE WESTERN COAST AND INTERIOR ALASKA IS A 955 MB LOW
PRESSURE THAT IS CENTERED OVER KIANA ALASKA AS OF 100 PM AKST.
THIS SYSTEM WILL CONTINUE TO MOVE NORTHEAST TOWARDS BRISTOL BAY
THROUGH SUNDAY. THIS SYSTEM WILL IMPACT ST LAWRENCE
ISLAND...BERING STRAIT COAST...AND THE YUKON DELTA OVERNIGHT WITH
STRONG WINDS AND SNOW ALLOWING FOR BLOWING SNOW AND REDUCED
VISIBILITIES ACROSS THE YUKON DELTA. CURRENT RADAR REFLECTIVITY
INDICATES THAT SNOW IS LOCATED JUST SOUTH OF BETHEL AND WILL
CONTINUE TO MOVE NORTHWARD TOWARDS MARSHALL WITHIN THE NEXT COUPLE
OF HOURS. AS OF 1 PM...SUSTAINED WIND SPEED AT MARSHALL WAS 42 MPH
WITH GUSTS OF 48 MPH. THUS WINTER WEATHER CONDITIONS MAY DEVELOP
EARLIER ACROSS SOUTHERN PORTIONS OF THE YUKON DELTA. THUS HAVE
DECIDED TO UPDATE THE WINTER WEATHER ADVISORY TO START NOW.
CONDITIONS WILL CONTINUE TO DEVELOP THROUGH THE EARLY EVENING FOR
NORTHERN PORTIONS OF THE YUKON DELTA WHICH INCLUDES EMMONAK.
EXPECT 2 TO 3 INCHES OF SNOW OVERNIGHT WITH AN ADDITIONAL HALF
INCH OF SNOW ON SUNDAY FOR THIS EVENT.

THIS SYSTEM IS CURRENTLY BRINGING GALE WINDS FOR COASTAL ZONES
EXTENDING FROM DALL POINT NORTHWARD TO WHALES...WHICH WILL EXPAND
NORTHWARD AS THE SYSTEM MOVES NORTHEAST TOWARDS CAPE BEAUFORT
OVERNIGHT. ALTHOUGH GAMBLE AND SAVOONGA OBSERVATIONS CURRENTLY
INDICATE WIND GUSTS UP TO 47 MPH...IT IS ANTICIPATED THAT WINDS
ACROSS THE AREA WILL INCREASE OVERNIGHT. THUS WILL KEEP THE HIGH
WIND WARNING IN EFFECT THROUGH TOMORROW MORNING.

SNOW WILL ALSO MOVE INTO SOUTHERN PORTIONS OF THE INTERIOR. THERE
WILL BE SLOW ACCUMULATION OF SNOW OVER THE NEXT SEVERAL DAYS WITH
A COUPLE OF DISTURBANCES MOVING ACROSS THE AREA. THERE WILL BE
SNOW DEVELOPING OVERNIGHT TONIGHT THROUGH MONDAY MORNING BRINGING
1 TO 2 INCHES THE SOUTHERN INTERIOR WITH LOCALIZED HIGHER AMOUNTS
OF 4 TO 6 INCHES ACROSS EASTERN ALASKA RANGE. AN UPPER LEVEL
DISTURBANCE WILL THEN MOVE ACROSS THE INTERIOR ON MONDAY AND
TUESDAY BRINGING ANOTHER SHOT OF SNOW POTENTIALLY UP TO 2 INCHES
ACROSS THE AREA. AS MENTIONED...IT SHOULD BE A SLOW SNOW
ACCUMULATION OVER A LONGER DURATION AND SHOULD NOT WARRANT ANY
TYPE OF WINTER WEATHER ADVISORIES FOR THE LONGER DURATION.

THE UNSETTLED WEATHER PATTERN WILL CONTINUE WEDNESDAY AS MODELS
SUGGEST ANOTHER STRONG SYSTEM MOVING OVER THE NORTHERN BERING SEA.
HOWEVER THERE IS SOME DISAGREEMENT IN THE STRENGTH AS THE GFS
INDICATES A CLOSED UPPER LEVEL LOW LOCATED SOUTH OF ST LAWRENCE
WHILE THE ECMWF INDICATES AN OPEN WAVE UPPER LEVEL DISTURBANCE. IN
EITHER CASE EXPECT UNSETTLED WEATHER.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
