TO A LOW JUST EAST OF THE NORTHERN KAMCHATKA PENINSULA. THERE IS A
SURFACE LOW OFF THE COAST OF THE PANHANDLE THAT IS MOVING TOWARDS
THE NORTHWEST. THERE IS AN UPPER LEVEL TROUGH AND LOW LEVEL FRONT
WELL SOUTH OF THE GULF OF ALASKA WITHIN THE MAIN STORM TRACK. THIS
SYSTEM HAS A LARGE PLUME OF MOISTURE AND IS BEGINNING TO CURVE
TOWARDS THE NORTH...AND WILL PLAY A SIGNIFICANT ROLL IN THE
FORECAST FROM SATURDAY AFTERNOON THROUGH SUNDAY.

.MODEL DISCUSSION...
THE NUMERICAL MODELS ARE IN DECENT AGREEMENT ON THE MAIN SYNOPTIC
FEATURES. THE GFS AND NAM ARE SLOWER WITH A LOW CROSSING THE
ALASKA PENINSULA SATURDAY NIGHT/SUNDAY THAN THE ECMWF AND
CANADIAN GEM. THE MAIN MODEL UNCERTAINTIES ARE WITH THE SYSTEM DUE
INTO SOUTHERN ALASKA SATURDAY NIGHT AND SUNDAY. THE GFS AND ECMWF
ARE BOLDLY PAINTING LARGE AMOUNTS OF PRECIPITATION TO MAKE IT OVER
THE COASTAL MOUNTAINS AND INTO THE ANCHORAGE AREA. THIS IS PARTLY
DUE TO CONVERGENCE OF LOW LEVEL WINDS AND MOISTURE...WITH AN 850
MB JET PROGGED AT 75 KTS OVER PRINCE WILLIAM SOUND AND DROPPING TO
10 KTS OR SO OVER THE COOK INLET AREA. THE NAM IS COMPLETELY DRY
AS IT KEEPS STRONGER LOW/MID LEVEL WINDS AND MORE DOWN-SLOPING.
LEANING A LITTLE TOWARDS THE WETTER SOLUTIONS...DUE TO THE HIGH
AMOUNTS OF MOISTURE AND HIGHER TRUST IN THE GFS AND ESPECIALLY THE
VERY CONSISTENT ECMWF.

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (DAYS 1 AND 2)...

THE FORECAST CHALLENGE THIS WEEKEND CENTERS AROUND A STORM SYSTEM
CURRENTLY SPINNING SOUTH OF KODIAK ISLAND. THIS SYSTEM PUSHES A
FRONT INTO THE SOUTHERN GULF LATE TONIGHT BRINGING MIXED
PRECIPITATION AND GUSTY WINDS. PRECIPITATION ACROSS THE SOUTHERN
WATERS INCLUDING KODIAK ISLAND...IS EXPECTED TO START AS SNOW AND
THEN MIX WITH RAIN OR CHANGE OVER COMPLETELY TO RAIN AS A WARMER
AIR MASS STREAMS IN FROM THE PACIFIC. THIS PATTERN IS EXPECTED
ALONG THE FRONT AS MOVES TO THE GULF COASTAL AREAS AND PRINCE
WILLIAM SOUND LATER SATURDAY. THE FRONT STALLS ALONG THE COAST
SATURDAY NIGHT...HOWEVER PRECIPITATION WILL SPREAD INLAND TOWARD
MIDNIGHT AS A LOW LEVEL JET INCREASES ACROSS THE PRINCE WILLIAM
SOUND TO THE SOUTHERN SUSITNA VALLEY. THE BIGGEST CHALLENGE WITH
THIS SYSTEM WILL BE PRECIPITATION TYPE ON SUNDAY ACROSS THE
ANCHORAGE BOWL AND MATANUSKA VALLEY. A COLD AIR MASS WILL BE
INITIALLY IN PLACE OVER THIS REGION AND MAY MODIFY TO JUST ABOVE
FREEZING DURING SUNDAY AFTERNOON...BRINGING A MIX OF RAIN AND SNOW
INTO SUNDAY EVENING. THE HEAVIEST PRECIPITATION THIS WEEKEND IS
EXPECTED ACROSS PRINCE WILLIAM SOUND...EASTERN KENAI AND ALONG THE
NORTHEAST COAST.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (DAYS 1 AND 2)...
SOUTHWEST ALASKA WILL REMAIN IN SOUTH TO EAST FLOW FOR THE NEXT
COUPLE DAYS. THE MAJORITY OF THE ACTIVE WEATHER WILL BE FROM THE
LOW SOUTH OF THE ALASKA PENINSULA AS ITS FRONT PUSHES INTO THE
ALEUTIAN RANGE THIS EVENING. HOWEVER...MOST OF THE RAIN AND SNOW
WILL GET HUNG UP ON THE MOUNTAINS WITH ONLY LIGHT SHOWERS MAKING
TO THE BRISTOL BAY AREA. THEN ON SATURDAY AN UPPER LEVEL WAVE
WILL PUSH IN FROM THE SOUTH HELPING TO BRING IN PRECIPITATION
FURTHER NORTH. OVERNIGHT SATURDAY SOME SNOW SHOWERS MAY MAKE IT TO
THE KUSKOKWIM DELTA.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (DAYS 1 AND 2)...
THE CURRENT PROBLEM IS THE DEFORMATION ZONE EXTENDING FROM JUST
WEST OF THE PRIBILOF ISLANDS THROUGH THE ALEUTIANS NEAR NIKOLSKI.
THERE ARE ALSO STRONG NORTHWEST WINDS IN THIS CORRIDOR PRODUCING
BLIZZARD CONDITIONS NEAR NIKOLSKI. HOWEVER...THE DEFORMATION ZONE
IS WEAKENING AND SHOULD DIMINISH ENOUGH LATER THIS EVENING FOR
CONDITIONS TO IMPROVE FOR NIKOLSKI. THEN NORTHWEST FLOW WILL
DOMINATE THE BERING AND ALEUTIANS BRINGING SNOW SHOWERS TO THE
AREA THROUGH SATURDAY.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...
THE OVERALL SYNOPTIC PATTERN FOR THE MID TO LONG TERM HAS CHANGED
LITTLE FROM YESTERDAY WITH MODELS CONTINUING TO SHOW A LARGE
AMPLITUDE RIDGE SPANNING FROM THE BROOKS RANGE SOUTHWARD ALONG THE
CONTINENTAL DIVIDE INTO THE WESTERN CONUS AND A BROAD TROUGH OVER
THE NORTHERN PACIFIC WITH CENTERS NEAR THE ALASKA PENINSULA AND
THE SEA OF OHKOSK.

AT THE SURFACE...A 960-970 MB LOW IS EXPECTED TO TRANSIT EASTWARD
ALONG THE ALEUTIAN CHAIN FROM SUNDAY EVENING /START OF DAY 3/ TO
A POSITION ROUGHLY SOUTH OF ADAK BY LATE MONDAY EVENING. BY
TUESDAY MORNING...THIS SYSTEM WILL BEGIN TO MERGE WITH A 980MB LOW
MOVING UP FROM THE NORTH PACIFIC ...FORMING A BROAD 960-970MB LOW
IN THE CENTERED IN THE VICINITY OF DUTCH HARBOR. THIS WILL PUT
MOST OF THE FORECAST AREA IN A BROAD CYCLONIC FLOW WITH SOUTH TO
EASTERLY FLOW OVER MOST OF SOUTHERN/SOUTHWESTERN ALASKA AND MAINLY
NORTHEAST FLOW OVER THE BERING SEA. THIS BROAD LOW IS EXPECTED TO
CONTINUE FOR THE REMAINDER OF THE FORECAST PERIOD WITH SHORTWAVES
ROTATING AROUND THE PARENT LOW.

THIS PATTERN WILL KEEP GENERALLY WET AND WARM WEATHER ALONG THE
NORTH GULF COAST AND PRODUCE A WARMING TREND THROUGH THE WEEK FOR
THE INTERIOR AREAS OF SOUTHERN/SOUTHWESTERN ALASKA.
