SOUTHERLY MID-LEVEL FLOW.

THE MOST PROMINENT WEATHER FEATURE IS A WELL-DEFINED FRONT IN THE
UPPER AND MID-LEVELS THAT EXTENDS FROM NEAR THE PRIBILOFS
EAST INTO SOUTHWEST ALASKA AND THEN THROUGH THE NORTHERN AND
WESTERN GULF OF ALASKA. THIS SYSTEM BROUGHT SEVERAL HOURS OF
FREEZING RAIN TO PARTS OF THE KUSKOKWIM DELTA LATE THIS MORNING
INTO EARLY AFTERNOON...WITH THE BETHEL AREA WARMING TO ABOVE
FREEZING AND CHANGING TO JUST A COLD RAIN BY EARLY AFTERNOON.
ADDITIONALLY...ON THE NORTH SIDE OF THE FRONT ABOUT AN INCH OF
SNOW FELL OVERNIGHT ON SAINT PAUL ISLAND AND CONTINUES THIS
AFTERNOON. MEANWHILE...ONSHORE FLOW BEHIND THIS FRONT IS BRINGING
ANOTHER ROUND OF RAIN AND LOW STRATUS TO SOUTHWEST ALASKA AND
KODIAK.

ELSEWHERE...SEASONABLY UNSETTLED WEATHER CONTINUES ACROSS THE
ALEUTIANS AS ANOTHER STORM SYSTEM SOUTH OF THE ALEUTIAN ISLANDS
RIDES ALONG THE ZONAL JET STREAM.

.MODEL DISCUSSION...

THE MODELS ARE ONCE AGAIN IN VERY GOOD OVERALL AGREEMENT ON THE
LARGE SCALE. WHERE THE MODELS ARE STRUGGLING IS TOWARD
SOUTHCENTRAL WITH THE DEPICTION OF THE DYNAMIC FEATURES AND
ASSOCIATED THERMODYNAMICS WITH THE UPPER LEVEL TROUGH AS IT MOVES
NORTHEAST TOWARD SOUTHCENTRAL ALASKA TONIGHT INTO THE WEEKEND.
THIS SETS UP A WIDE RANGE OF POSSIBILITIES WITH REGARD TO
PRECIPITATION AMOUNTS AND PRECIPITATION TYPE IN THE COOK INLET
REGION. THE GFS IS PERHAPS MOST AGGRESSIVE IN SHUNTING MOST OF THE
ENERGY TO THE NORTH AND EAST OF THE COOK INLET...WHILE MODELS SUCH
AS THE GEM REGIONAL BRINGS BANDED PRECIPITATION TO THE COOK INLET
WHICH COULD CONTRIBUTE ENOUGH DYNAMIC COOLING FOR SNOW
ACCUMULATIONS ACROSS PARTS OF THE UPPER COOK INLET REGION. THIS
RESULTS IN A SOMEWHAT MURKY FORECAST FOR THE NEXT FEW DAYS FOR
SOUTHCENTRAL ALASKA...THOUGH WITH HIGHER CONFIDENCE ELSEWHERE.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (DAYS 1 AND 2)...
THE UPPER LEVEL TROUGH APPROACHING THE AKPEN WILL BE THE FOCAL
POINT FOR A RETURN TO MORE ACTIVE WEATHER FOR THE SOUTH MAINLAND
INTO THE WEEKEND. A SHORTWAVE MOVING AHEAD OF THE UPPER LOW WILL
BRING WIDESPREAD RAIN BACK TO THE GULF COAST...WITH A RAIN/WET
SNOW MIX ALONG HIGHER ELEVATIONS. INTERIOR SOUTHCENTRAL MAY
RECEIVE ISOLATED RAIN OR SNOW SHOWERS FROM THIS FEATURE...BUT
WITH LIMITED AVAILABLE MOISTURE MOST OF THE PRECIPITATION SHOULD
FALL OVER THE WINDWARD SIDE OF THE GULF. THIS SHOULD CHANGE ON
FRIDAY EVENING AS THE UPPER LEVEL TROUGH APPROACHES THE SOUTH
MAINLAND...BRINGING WITH IT INCREASED MOISTURE AND A BETTER CHANCE
FOR PRECIPITATION INTO SOUTHCENTRAL. THE MODELS HAVE TRENDED
SLIGHTLY WARMER AND FURTHER TO THE EAST WITH THE UPPER LEVEL LOW
SINCE YESTERDAY...AND AS A RESULT WE EXPECT ALL PRECIPITATION TO
FALL AS RAIN OVER THE ANCHORAGE BOWL AND MATANUSKA VALLEY THROUGH
FRIDAY EVENING WHEN IT MAY BEGIN TO MIX OR CHANGE OVER TO A WET
SNOW. BECAUSE OF THIS DELAYED START TO THE SNOW AND BECAUSE THE
STRONGEST DYNAMICS SHOULD REMAIN OFF TO THE EAST...WE NO LONGER
EXPECT MORE THAN AN INCH OR SO OF WET SNOW ACCUMULATION TO THE
LOWER ELEVATIONS FROM THIS EVENT. AS THE UPPER LOW PASSES OVERHEAD
ON SUNDAY...PRECIPITATION SHOULD BEGIN TO DIMINISH FROM WEST TO
EAST...WITH SKIES REMAINING CLOUDY INTO SUNDAY.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (DAYS 1 AND 2)...
A TROUGH PROGRESSING NORTHWARD ACROSS THE MAINLAND CONTINUES TO
BRING LIGHT RAIN TO MOST OF THE AREA. THE WARM NOSE OVER THE
KUSKOKWIM DELTA SEEMS TO HAVE MOSTLY ERODED...THOUGH POCKETS OF
LIGHT FREEZING RAIN REMAIN POSSIBLE TONIGHT BOTH OVER THE DELTA
AND IN THE KUSKOKWIM VALLEY AS WELL. SNOW WILL CONTINUE OVER THE
KUSKOKWIM DELTA COAST AS RAIN TRANSITIONS TO SNOW OVERNIGHT
INLAND. FOR THE BRISTOL BAY AREA...RAIN WILL TAPER OFF SOMEWHAT
OVERNIGHT AS THE TROUGH EXITS TO THE NORTH BUT SOME LIGHT
PRECIPITATION WILL BE LEFT OVER IN THE NORTHERN PORTIONS. ANOTHER
WEAKER UPPER LEVEL SYSTEM MOVES OVERHEAD FRIDAY MORNING LINGERING
THE CHANCE FOR LIGHT RAIN OVER MUCH OF THE AREA. SATURDAY WILL SEE
A DRYING TREND ALBEIT TEMPORARILY AS THE UPPER LOW EXITS THE
REGION.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (DAYS 1 AND 2)...
A COMPLEX LOW PRESSURE SYSTEM SITS OVER MUCH OF THE BERING BUT THE
SYSTEM AS A WHOLE IS WEAKENING. LIGHT SNOW WILL CONTINUE OVER THE
PRIBILOFS BEFORE TAPERING OFF IN THE MORNING. A WEAK DISTURBANCE
WILL MOVE OVER THE ALASKA PENINSULA THIS EVENING BRINGING LIGHT
RAIN...WITH SNOW AFTER MIDNIGHT. THINGS DRY OUT LATE FRIDAY OVER
THE EASTERN BERING...HOWEVER A STRONG LOW PRESSURE SYSTEM AND
FRONT MOVE OVER THE WESTERN CHAIN AT THAT TIME. THIS SYSTEM WILL
FEATURE GALE TO MINIMUM STORM FORCE WINDS ALONG WITH RAIN AND
SNOW. THE FRONT WILL MOVE INTO THE CENTRAL AND WESTERN BERING BY
LATE SATURDAY NIGHT.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...

A BROAD TROUGH SITTING OVER MAINLAND ALASKA AND THE GULF OF ALASKA
ON SATURDAY WILL EXIT TO THE EAST SATURDAY NIGHT INTO SUNDAY. PRECIP
WILL LINGER MAINLY ALONG THE MOUNTAINS OF SOUTHCENTRAL...PRIMARILY
SOUTH TO WEST FACING SLOPES. FARTHER WEST....A SHARP ARCTIC TROUGH
WILL MOVE ONSHORE OF WESTERN ALASKA SATURDAY NIGHT...THEN LIFT
NORTHEASTWARD SUNDAY BY A BUILDING RIDGE OUT AHEAD OF A DEEP STORM
ALONG THE ALEUTIANS. MODELS DIFFER ON HOW QUICKLY THE TROUGH WILL
LIFT NORTHWARD...AND THUS DIFFER ON WHETHER THE KUSKOKWIM DELTA
AND VALLEY WILL SEE SNOW OUT OF THIS. HAVE STUCK WITH CHANCE
POPS...BUT IT IS LOOKING INCREASINGLY LIKELY THAT SOMEWHERE IN
THIS REGION WILL SEE A BIT OF SNOW.

MEANWHILE...THE FRONTAL SYSTEM ASSOCIATED WITH THE DEEP LOW SOUTH
OF THE ALEUTIAN CHAIN WILL SPREAD NORTH AND EAST INTO THE EASTERN
BERING SEA. A RIDGE SITTING OVER THE NORTHERN TO WESTERN BERING
WITH DEEP ARCTIC AIR WILL REALLY TIGHTEN UP PRESSURE GRADIENTS
ACROSS THE SOUTHERN BERING/PRIBILOF ISLANDS AND REALLY HELP STALL
THE NORTHWARD MOMENTUM OF THE FRONT. THIS WILL PRODUCE AN AREA OF
STORM FORCE WINDS ALONG WITH SNOW AND BLOWING SNOW ON THE LEADING
EDGE OF PRECIPITATION. EXPECT PRIBILOF ISLANDS WILL BE WARM ENOUGH
TO PREVENT DEVELOPMENT OF BLIZZARD CONDITIONS...BUT WILL CERTAINLY
KEEP AN EYE ON THIS THE NEXT COUPLE DAYS.

AS HAS BEEN ADVERTISED...A MAJOR CHANGE IN THE PATTERN WILL
RAPIDLY ENSUE AS A STRONG POLAR JET STREAK OVER THE NORTHWEST
PACIFIC ON SATURDAY DIVES SOUTHEASTWARD TO AROUND 30N LATITUDE
SUNDAY NIGHT LEADING TO A RAPIDLY BUILDING RIDGE DOWNSTREAM. A
STRONG SOUTHERLY JET WILL DEVELOP ON THE WEST SIDE OF THIS RIDGE
AND INTERACT WITH THE FRONTAL SYSTEM AS IT PUSHES TOWARD MAINLAND
ALASKA ON SUNDAY. THE END RESULT WILL BE A NORTHWARD SURGE OF WARM
AND WET CONDITIONS ACROSS SOUTHCENTRAL AND SOUTHWEST ALASKA SUNDAY
THROUGH SUNDAY NIGHT.

ALTHOUGH THIS IS A FAIRLY COMMON WEATHER PATTERN FOR ALASKA...IT
IS MUCH RARER THIS TIME OF THE YEAR WHEN THE MAINLAND HEADS INTO
WHAT IS CLIMATOLOGICALLY THE DRIEST TIME OF YEAR. ONCE A PATTERN
LIKE THIS DEVELOPS IT TENDS TO REMAIN IN PLACE FOR A WEEK OR MORE.
THUS...EXPECT THE WARM AND RAINY CONDITIONS TO PERSIST AS WE HEAD
THROUGH NEXT WEEK. MODELS ALL INDICATE A SERIES OF WAVES MOVING UP
THE WEST SIDE OF THE RIDGE THROUGH THE END OF NEXT WEEK...CREATING
PERTURBATIONS IN THE PLACEMENT OF THE RIDGE (AND THE FIREHOSE OF
WARM AIR AND MOISTURE). THERE IS A FAIRLY LARGE SPREAD IN THE
LATEST GUIDANCE...AND RUN TO RUN CONSISTENCY IS POOR. THIS MAKES
IT DIFFICULT TO DETERMINE WHERE THE HEAVIEST RAIN WILL FALL AND
WHERE THE WARMEST AIR WILL ADVECT. THE BIGGEST CONCERN WILL BE
POTENTIAL FOR LOCALIZED FLOODING WITH FREEZING LEVELS EXPECTED TO
RISE TO 5000 FEET OR HIGHER (POTENTIALLY AS HIGH AS 7000 FEET IN
THE WARMEST AREAS). THE COMBINATION OF HEAVY RAIN AND MELTING SNOW
(AND RIVER ICE) WILL LEAD TO THE BEGINNING OF BREAK-UP IN SOME
AREAS....WITH A LOT OF WATER MOVING THROUGH AREA RIVERS AND
STREAMS. WILL CLOSELY MONITOR THIS OVER THE COMING DAYS AND
PROVIDE MORE DETAILS AS FORECAST CONFIDENCE INCREASES.
