SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
512 PM AKST THU DEC 17 2015

.ANALYSIS AND UPPER LEVELS...

UPPER LEVEL PATTERN CONTINUES TO SHOW A CUT-OFF UPPER LOW OVER THE
CENTRAL GULF OF ALASKA AND ANOTHER UPPER LOW CENTER OVER THE
KAMCHATKA PENINSULA WITH STRONG RIDGING IN BETWEEN. AT THE
SURFACE THIS IS REFLECTED WITH A VERTICALLY STACKED LOW PRESSURE
SYSTEM IN THE CENTRAL GULF AND A MORE DYNAMIC LOW PRESSURE CENTER
MOVING INTO THE FAR WESTERN BERING. A STORM FORCE FRONT ASSOCIATED
WITH THE BERING SEA LOW IS CURRENTLY PROGRESSING EASTWARD THROUGH
THE ALEUTIANS AND WILL CONTINUE ON THAT TRACK THROUGH TODAY.
WESTERLY WINDS BEHIND THE FRONT WILL COMBINE WITH STRONG COLD AIR
ADVECTION TO BRING WARNING LEVEL WINDS TO THE WESTERN
ALEUTIANS...HOWEVER AS THE FRONT WEAKENS RAPIDLY WARNING LEVEL
CONDITIONS ARE NOT EXPECTED FURTHER EAST. OVER THE MAINLAND A
TROUGH ASSOCIATED WITH THE LOW IN THE GULF OF ALASKA HAS MOVED
ONSHORE AND IS BRINGING MOSTLY SNOW TO THE MAINLAND. WINDS ARE
SLOWLY SHIFTING TO NORTHWEST ACROSS THE AREA AS THE LOW SLIDES OFF
TO THE SOUTHEAST. THE NORTHWESTERLY FLOW WILL BRING MORE COLD AIR
ADVECTION AND THE FEW POCKETS OF RAIN SHOULD CHANGE OVER AND TAPER
OFF AS THE COLD AIR MOVES IN.

&&

.MODEL DISCUSSION...

MODELS REMAIN IN GOOD AGREEMENT FOR TODAY...BUT START TO DIFFER
VERY QUICKLY. THERE ARE SOME MINOR DIFFERENCES IN FRONTAL
PLACEMENT IN THE WEST...WITH GFS/ECMWF IN GREATER AGREEMENT. THE
GFS SOLUTION WAS CHOSEN AS THE BASIS FOR TODAYS FORECAST. AFTER
THE THURSDAY TIME PERIOD THE MODELS BEGIN TO DISAGREE AS THE
FRONT IN THE BERING APPROACHES THE MAINLAND. THE FORECAST IS FOR A
LOW TO FORM ALONG THE TRIPLE POINT...HOWEVER ALL THE MODELS
DISAGREE ON WHERE THIS IS GOING TO OCCUR. GFS WAS CHOSEN AS THE
MOST LIKELY SOLUTION FOR THIS PERIOD AS WELL...WHICH WILL PUSH THE
TRIPLE POINT LOW OVER THE KENAI PENINSULA AND THEN FURTHER EAST
INTO THE NORTHERN GULF. CONFIDENCE IN THE FORECAST FOR THIS
PERIOD IS MODERATE TO LOW GIVEN MODEL DISAGREEMENT.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (DAYS 1 AND 2)...
THE WEAKENING LOW OVER THE SOUTHERN GULF WILL CONTINUE TO BRING
DIMINISHING OUTFLOW WINDS AND RAIN/SNOW SHOWERS TONIGHT AS CONDITIONS
CLEAR FROM WEST TO EAST IN ADVANCE OF A WEAK SHORTWAVE RIDGE. THE
FOCUS FOR THE AREA WILL THEN QUICKLY SHIFT TO THE FRONTAL SYSTEM
CURRENTLY MOVING THROUGH THE EASTERN BERING. THIS FRONT WILL BRING
GALE FORCE WINDS AND RAIN/SNOW THROUGHOUT THE GULF BY FRIDAY
EVENING. THE TEMPERATURES FROM THIS SYSTEM SHOULD REMAIN COOL
ENOUGH TO KEEP PRECIP TYPE AS SNOW FOR THE HIGHER ELEVATIONS ALONG
THE GULF COAST (SUCH AS TURNAGAIN AND THOMPSON PASS)...BUT STILL
WARM ENOUGH TO KEEP ANY MAJOR BLOWING SNOW CONCERNS LOW WITH THE
GUSTY WINDS THAT WILL ACCOMPANY THIS SYSTEM. THE ONE BIG QUESTION
FROM THIS SYSTEM WILL BE THE EXACT PLACEMENT OF A WEAK LOW THAT
WILL DEVELOP IN THE WESTERN GULF FRIDAY EVENING. PREVIOUS RUNS OF
THE GFS AND NAM HAD ALL BROUGHT THIS LOW ONSHORE NEAR PRINCE
WILLIAM SOUND ON SATURDAY...BRINGING A FEW INCHES OF SNOW INTO
SOUTHCENTRAL. SINCE THEN THE 18Z RUNS OF THE NAM AND GFS HAVE
TRENDED SIGNIFICANTLY TO THE SOUTH BY STALLING THE LOW OVER THE
NORTHERN-CENTRAL GULF. THIS WILL BEAR WATCHING IN FUTURE MODEL
RUNS...BUT CONFIDENCE IS BEGINNING TO DIMINISH FOR THE CHANCE OF
ACCUMULATING SNOW TO SOUTHCENTRAL THIS WEEKEND.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (DAYS 1 AND 2)...
THE SOUTHWEST MAINLAND WILL SEE ONE MORE NIGHT OF FAIRLY BENIGN
CONDITIONS CHARACTERIZED BY CLEAR SKIES AND COLD TEMPERATURES
BEFORE THE FRONT OVER THE BERING ARRIVES ALONG THE COAST EARLY
FRIDAY MORNING ACCOMPANIED BY SNOW AND GUSTY SOUTHEAST WINDS. THE
MAIN FORECAST CHALLENGE WITH THIS SYSTEM WILL BE DETERMINING THE
POTENTIAL FOR BLOWING SNOW AS THE FRONT WEAKENS RATHER QUICKLY
UPON REACHING THE COAST AND PUSHING INLAND...WITH WINDS
DIMINISHING ACCORDINGLY DURING THE AFTERNOON. THIS SUGGESTS A
RELATIVELY BRIEF WINDOW FOR BLOWING SNOW...WITH THE BEST CHANCE
DURING THE MORNING ALONG THE COAST OF THE KUSKOKWIM DELTA AND THE
WESTERN CAPES OF BRISTOL BAY. VISIBILITIES ARE NOT EXPECTED TO
REACH ADVISORY CRITERIA AT THIS TIME...BUT SOME LOCALIZED
REDUCTIONS TO ONE MILE OR LESS WILL BE POSSIBLE...PARTICULARLY FOR
LOCATIONS NORTH AND WEST OF BETHEL. SNOW WILL QUICKLY TAPER OFF TO
SHOWERS ON FRIDAY NIGHT AS THE WEAKENING FRONT PUSHES THROUGH THE
KUSKOKWIM VALLEY. AN AREA OF STEADIER SNOW WILL LINGER OVER
EASTERN PORTIONS OF THE BRISTOL BAY ZONE THROUGH FRIDAY NIGHT
AIDED BY A TRIPLE POINT LOW FORMING ALONG THE FRONT IN THE
VICINITY OF THE WESTERN GULF...WITH LOCATIONS ALONG THE ALEUTIAN
RANGE POSSIBLY PICKING UP SEVERAL ADDITIONAL INCHES OF SNOW BY
SATURDAY MORNING.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (DAYS 1 AND 2)...
THE DEEP LOW ENTERING THE WESTERN BERING AND THE ASSOCIATED FRONT
CURRENTLY APPROACHING THE EASTERN ALEUTIANS AND PRIBILOF ISLANDS
WILL CONTINUE TO BE THE DOMINANT FEATURES IMPACTING THE REGION
THROUGH THE END OF THE WORK WEEK. RAIN AND SNOW WILL QUICKLY
SPREAD EASTWARD ACROSS THE AKPEN BY LATE TONIGHT AS THE FRONT
NEARS THE COAST...WITH PRECIPITATION QUICKLY CHANGING TO ALL RAIN
AS WARM NORTH PACIFIC AIR MOVES IN BEHIND THE FRONT.
MEANWHILE...THERE IS NOW BETTER AGREEMENT ON THE TRACK OF THE LOW
THROUGH THE NORTH CENTRAL BERING...WITH COLD ADVECTION IN WESTERLY
FLOW ON THE SOUTHERN PERIPHERY OF THE LOW SUPPORTING A LARGE
SWATH OF STORM FORCE WINDS THAT WILL SPREAD EASTWARD THROUGH
SATURDAY. WINDS WILL CONTINUE TO RAMP UP THROUGH TONIGHT ACROSS
THE WESTERN ALEUTIANS...WHERE A HIGH WIND WARNING REMAINS IN
EFFECT THROUGH FRIDAY AFTERNOON. AFTER THAT...THE STRONGEST WINDS
ARE EXPECTED TO REMAIN NORTH OF THE CENTRAL ALEUTIANS...WITH GUSTS
THROUGH FRIDAY NIGHT TOPPING OUT AROUND 70 MPH JUST SHY OF HIGH WIND
CRITERIA.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...
THE BARREN ISLANDS WILL HAVE A TRIPLE POINT LOW DEVELOP ON
SATURDAY WITH AN ASSOCIATED WEATHER FRONT EXTENDING THROUGH THE
CENTRAL GULF. THIS SYSTEM WILL TRANSITION TO THE NORTHERN GULF
BEFORE BECOMING STATIONARY. AN UPSTREAM WEAK LOW PRESSURE SYSTEM
IN THE BRISTOL BAY AREA MOVES INTO THE GULF BY MONDAY. THESE TWO
SYNOPTIC FEATURES WILL PHASE INTO A BROAD AREA OF LOW PRESSURE
OVER THE NORTHERN GULF BEFORE GRADUALLY MOVING TO THE SOUTHEAST BY
MIDWEEK. THE MAJORITY OF THE PRECIPITATION WILL OCCUR ALONG THE
NORTHERN GULF COASTAL COMMUNITIES EXCEPT FOR A BRIEF PERIOD OF
SNOW AND RAIN UP THROUGH COOK INLET EXTENDING INTO THE LOWER
MATANUSKA VALLEY ON SATURDAY. THE SOUTHCENTRAL REGION WILL MAINLY
HAVE OFFSHORE FLOW WITH NORTHERLY WINDS BY EARLY NEXT WEEK AND
TEMPERATURES WILL BE COOLER WITH COLDER AIR FILTERING IN FROM THE
NORTH.

MEANWHILE THE CENTRAL TO NORTHERN BERING SEA WILL HAVE A STORM
FORCE LOW POSITIONED NORTH OF SAINT PAUL ON SATURDAY. THIS WILL
BRING WIDESPREAD WESTERLY GALE FORCE WINDS IN THE LOWER BERING SEA
SPREADING INTO THE ALEUTIAN CHAIN. BY SUNDAY THIS SYSTEM WILL BE
CROSSING THROUGH THE BRISTOL BAY REGION BEFORE ENTERING THE GULF.
WHILE A GALE FORCE LOW DROPS DOWN FROM THE KAMCHATKA PENINSULA
WITH A SECONDARY LOW FORMING OVER THE WESTERN BERING SEA. THIS
SYSTEM BECOMES ELONGATED ALONG THE ALEUTIANS PRODUCING SHOWERS AND
GUSTY WINDS ALONG THE CHAIN AND THE LOWER BERING SEA. THE MODELS
ARE STRUGGLING WITH THIS COMPLEX SYSTEM AND FORECAST CONFIDENCE IS
LOW GOING INTO THE EARLY PART OF NEXT WEEK. THE JET IS ZONAL
DURING THIS TIMEFRAME AND WILL MOVE THIS SYSTEM INTO THE NORTH
PACIFIC. BY WEDNESDAY AN UPPER LEVEL CLOSED LOW FORMS OVER THE
WESTERN ALEUTIANS. THE MODELS ARE HAVING DIFFICULTY WITH THE
STRENGTH AND PLACEMENT OF THIS DEVELOPING LOW BEFORE ENTERING THE
BERING SEA BY MIDWEEK.
