NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
449 AM AKST SUN DEC 20 2009

.DISCUSSION...
THE ACTIVE AND HIGH IMPACT WEATHER WILL CONTINUE ALONG THE WEST
COAST INTO MONDAY NIGHT. A SERIES OF LOWS WILL IMPACT THE AREA WITH
BLIZZARD CONDITIONS...HIGH WINDS...AND POSSIBLY SOME FREEZING RAIN.
THE STORMINESS WILL GRADUALLY WIND DOWN BY LATE MONDAY NIGHT INTO
TUESDAY MORNING AS THE LAST IN A SERIES OF LOWS PULLS WELL WEST OF
THE MAINLAND.

AN UPPER LOW COMPLEX COVERS JUST ABOUT ALL OF THE BERING SEA. THE
COMPLEX HAS MULTIPLE LOW CENTERS THAT COMPLICATE THINGS
SIGNIFICANTLY...AND MAKE TIMING OUT SURFACE FEATURES DIFFICULT.  THE
PRIMARY SURFACE LOW EARLY THIS MORNING IS A 958 MB LOW ABOUT 150
MILES WEST OF THE PRIBILOF ISLANDS.  THIS LOW WILL LIFT TO THE NORTH
THIS MORNING BEFORE GRADUALLY TAKING A TURN TO THE WEST BY TONIGHT.
ANOTHER LOW IS DEVELOPING SOUTH OF THE ALEUTIANS AND IS EXPECTED TO
DEEPEN AND MOVE TO THE SOUTH OF NUNIVAK ISLAND BY THIS EVENING. A
THIRD LOW LIFTS NORTH TO NEAR NUNIVAK ISLAND ON MONDAY. THE NAM
LOOKS TO BE A STRONG OUTLIER WITH THE THE LAST IN THE SERIES OF
LOWS AS IT IS MUCH WEAKER THAN EITHER THE GFS/UKMET/ECMWF THAT ALL
HAVE THE LOW AS A SUB 960 MB CENTER IN THE VCNTY OF SAINT MATTHEW
ISLAND.

WEST COAST...NUMEROUS BLIZZARD AND WINTER STORM WARNINGS ARE IN
EFFECT ALONG THE WEST COAST.  WILL UPGRADE THE BLIZZARD WATCH TO A
BLIZZARD WARNING ALONG THE CHUKCHI SEA COAST...AND WILL ALSO EXTEND
THE BLIZZARD WARNINGS NORTH OF THE SEWARD PENINSULA INTO MONDAY
NIGHT. AREAS SUCH AS KOTZEBUE AND KIVALINA STAND TO SEE A 36 TO 48
HOUR PERIOD OF BLIZZARD CONDITIONS.  THE FORECAST BECOMES EVEN MORE
OF A CHALLENGE ALONG THE Y-K DELTA COAST AND PARTS OF THE LOWER
YUKON VALLEY AS THE PRECIPITATION MAY CHANGE TO A PERIOD OF FREEZING
RAIN AFTER THE BLIZZARD CONDITIONS END THIS EVENING.  WILL LIKELY
NEED TO TRANSITION FROM BLIZZARD WARNINGS TO WINTER STORM AND/OR
HIGH WIND WARNINGS.  HEAVY SNOW STILL LOOKS LIKELY ACROSS THE
NULATO HILLS WHERE STORM TOTALS WILL LIKELY EXCEED A FOOT IN SPOTS.
THE SREF HAS 60-70 PCT PROBABILITIES OF MORE THAN HALF A FOOT OF
SNOW ACROSS THE NULATO HILLS AND ACROSS THE HIGHER TERRAIN OF THE
SEWARD PENINSULA FOR THE 12 HOUR PERIOD ENDING AT 12Z MONDAY. THE
ACTIVE WEATHER ALONG THE WEST COAST WILL GRADUALLY WIND DOWN LATE
MONDAY NIGHT INTO TUESDAY MORNING AS THE LAST OF THE LOWS PULLS
WELL WEST OF THE MAINLAND. A WIND ADVISORY WAS ISSUED FOR AREAS
NEAR THE AK RANGE IN ZONE 227 AS FAREWELL LAKE WAS ALREADY GUSTING
OVER 40 MPH YESTERDAY EVENING AND THE WINDS WILL LIKELY CONTINUE
TO INCREASE TODAY.

INTERIOR...THE BIGGEST FORECAST CHALLENGE THE NEXT FEW DAYS WILL BE
TEMPERATURES AS A RAPID WARM-UP IS UNDERWAY...AND STRONG
TEMPERATURE INVERSIONS RAPIDLY DEVELOPED. THE 850MB TEMP ON THE
00Z SOUNDING WARMED UP 17C/24 HOURS...WITH CONTINUED SIGNIFICANT
WARMING EXPECTED INTO MONDAY. TEMPERATURE WERE ALREADY AS WARM AS
24F AT 900 MILLIBARS ON THE 12Z PAFA SOUNDING...AND THE
TEMPERATURES HAVE MODERATED INTO THE TEENS ON THE HIGHER HILLTOPS
AROUND FAIRBANKS. MOST OF THE VALLEYS ARE STILL 15 TO 20 BELOW
EARLY THIS MORNING. TEMPS ON THE HIGHER SUMMITS WILL LIKELY REACH
NEAR FREEZING BY LATE TONIGHT OR MONDAY MORNING WHILE TEMPS IN THE
DEEPER VALLEYS WILL BE SLOWER TO RESPOND. BY MONDAY MOST OF THE
INTERIOR VALLEYS WILL BE ABOVE ZERO WITH THE EXCEPTION OF THE
YUKON FLATS AND PERHAPS PARTS OF THE UPPER TANANA VALLEY.

STRONG WIND CONTINUES AT ANTLER CREEK WITH GUSTS TO AROUND 60 MPH.
WILL CONTINUE THE WINTER WEATHER ADVISORY FOR A COMBINATION OF THE
WIND AND BLOWING SNOW. THIS WINTER WEATHER ADVISORY WILL PROBABLY
NEED TO BE MORPHED INTO A WIND ADVISORY AS TEMPS CONTINUE TO RISE
AND BLOWING SNOW BECOMES LESS OF A CONCERN.

NORTH SLOPE...THE PRESSURE GRADIENT WILL GRADUALLY TIGHTEN UP ALONG
THE ARCTIC COAST THROUGH TONIGHT...AND WILL LIKELY LEAD TO SOME
BLOWING SNOW TONIGHT AND MONDAY.  WILL HOLD OFF ON ANY WINTER
WEATHER ADVISORIES FOR BLOWING SNOW...BUT THIS IS SOMETHING THAT
WILL NEED TO BE MONITORED.  THE BEST CHANCE OF SNOW WILL BE ALONG
PARTS OF THE WESTERN ARCTIC COAST ON MONDAY.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
