SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
537 AM AKDT TUE APR 26 2016

.ANALYSIS AND UPPER LEVELS...
A LARGE UPPER LEVEL LOW REMAINS CENTERED SOUTH OF THE ALASKA
PENINSULA. A FAIRLY STRONG FRONT ASSOCIATED WITH THIS LOW HAS
STALLED IN THE NORTHERN GULF OF ALASKA. THERE IS ALSO A SURFACE
LOW TO THE SOUTH OF THE UPPER LOW CENTER THAT IS MOVING TO THE
NORTHEAST. THERE IS ANOTHER UPPER LOW SOUTH OF THE WESTERN
ALEUTIANS. ANOTHER SURFACE LOW IS JUST TO THE EAST OF THIS UPPER
LOW CENTER AND IS BEGINNING TO MOVE NORTHEAST. THE JET IS
PRIMARILY SITUATED WELL SOUTH OF THE REGION EXCEPT FOR A NARROW
CORE THAT EXTENDS UP THROUGH THE GULF OF ALASKA WHICH IS
REINFORCING WINDS ACROSS THE NORTHWEST GULF...COOK INLET...AND
TURNAGAIN ARM. THERE IS A LARGE UPPER RIDGE DRAPED ACROSS CENTRAL
ALASKA AND THE NORTHERN AND WESTERN BERING SEA. THIS RIDGE IS AN
EXTENSION OF THE PERSISTENT WESTERN NORTH AMERICA RIDGE.

&&

.MODEL DISCUSSION...
MODELS REMAIN IN RATHER GOOD SYNOPTIC AGREEMENT LENDING TO
MODERATE TO HIGH OVERALL FORECAST CONFIDENCE. THE FEW AREAS WHERE
THERE IS SOME DISAGREEMENT ARE THE STRENGTH OF A TRIPLE POINT LOW
EARLY THU AND EXACT TIMING OF THE FRONTS MOVING INLAND. MANY OF
THE MODELS ARE NOW HINTING AT A LOW FORMING ALONG THE FRONT
SOUTHEAST OF KODIAK ISLAND THU MORNING. OVERNIGHT...MODELS HAVE
TRENDED TOWARD A CLOSED AND SLIGHTLY STRONGER LOW. THE GFS IS NOW
THE OUTLIER CONTINUING TO SHOW IT AS AN OPEN WAVE. BUT EVEN THE
GFS ENSEMBLE MEAN IS SHOWING A CLOSED LOW. THE FORECAST WAS
TRENDED IN THAT DIRECTION. AS FOR TIMING EACH SUCCESSIVE FRONT AS
THEY MOVE INTO THE GULF COAST...HI-RESOLUTION MODELS WERE USED.
TIMING OF LOCAL EFFECTS WINDS...TO INCLUDE THE TURNAGAIN
WIND...AND MOW MUCH IF ANY PRECIPITATION CAN OVERCOME THE
DOWNSLOPE FLOW REMAINS SOMEWHAT UNCERTAIN.

&&

.AVIATION...12Z ANCHORAGE TAF...THE GUSTY SOUTHEAST TURNAGAIN
WINDS SHOULD MAKE AN APPEARANCE ONCE AGAIN THIS AFTERNOON. THE
TIMING OF THE WINDS COULD VARY BY AN HOUR OR TWO DEPENDING ON HOW
MUCH CLEARING/HEATING THERE IS IN THE SUSITNA VALLEY. CROSS-
BARRIER FLOW OVER THE CHUGACH SHOULD KEEP SHOWERS CONFINED TO THE
MOUNTAINS. ONCE THE FRONT MOVES THROUGH THIS EVENING...THIS WILL
GIVE US THE BEST CHANCE FOR ANY SHOWERS AT THE TERMINAL AND WILL
ALSO SERVE TO KEEP THE SOUTHEAST WINDS BLOWING THROUGH MOST OF THE
NIGHT.

&&

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

A FRONT STALLED ALONG THE NORTHERN GULF WILL KEEP GUSTY WINDS
ALONG THE NORTHEAST COAST THROUGH THE EARLY AFTERNOON BEFORE
TAPERING DOWN AS THE FRONT LIFTS NORTH. RAIN WILL ALSO CONTINUE TO
DEVELOP ALONG THE BOUNDARY FROM THE EASTERN KENAI TO NORTHEAST
GULF. THE FRONT WEAKENS AS IT PUSHES INLAND THIS EVENING...HOWEVER
A FEW SHOWERS ARE POSSIBLE ACROSS INLAND LOCATIONS AS THE BOUNDARY
MOVES NORTH. GUSTY WINDS INCREASE LATE TODAY ACROSS THE ANCHORAGE
BOWL AND MATANUSKA VALLEY AS THE FRONT MOVES NORTH...THEN DIMINISH
BY MIDNIGHT AS THE SYSTEM WEAKENS.

AN UPPER LEVEL DISTURBANCE MOVES ACROSS THE GULF TONIGHT KEEPING
SCATTERED RAIN ACTIVITY ALONG THE COASTS AND OFFSHORE WITH THE
NEXT FRONT MOVING INTO THE SOUTHERN GULF WEDNESDAY AFTERNOON. THIS
SYSTEM THEN PROGRESSES TO THE NORTHERN COAST WEDNESDAY NIGHT.

&&

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

A PERSISTENT PATTERN OF EASTERLY FLOW ALOFT WILL CONTINUE THROUGH
THURSDAY AS THE CURRENT NORTH PACIFIC LOW WEAKENING AND SPLITTING
OVER THE ALEUTIAN CHAIN IS REPLACED BY ANOTHER. A SHORTWAVE TROUGH
EMBEDDED WITHIN THE FIRST LOW RETROGRADING IN FROM THE GULF OF
ALASKA TODAY WILL HELP SPARK INSTABILITY DRIVEN RAIN SHOWERS
ACROSS THE REGION THIS AFTERNOON AND EARLY EVENING.
THEREAFTER...NUMEROUS WEAK AND ILL-DEFINED DISTURBANCES WILL KEEP
PERIODIC SHOWERS AND RAIN CHANCES OVER SOUTHWEST WITH LITTLE TO NO
CHANGE IN THE SENSIBLE WEATHER.

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (DAYS 1 AND 2)...

SATELLITE IMAGERY THIS MORNING REVEALS ANOTHER PACIFIC LOW MOVING
TOWARD THE CENTRAL ALEUTIAN...WITH THE LEFTOVER AND WEAKENING
REMNANTS OF THE PREVIOUS NPAC GALE FORCE LOW OVER THE EASTERN
ALEUTIANS. THIS AFOREMENTIONED LOW WILL REPLACE THE WEAKENING
LOW WITH RAIN AND SHOWERS THROUGH THURSDAY AS THIS LOW SLOWLY
WEAKENS AND DRIFTS EASTWARD...KEEPING BROAD CYCLONIC FLOW OVER THE
BERING.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...
NO BIG CHANGES IN THE WEATHER FOR THE EXTENDED PERIOD. WEDNESDAY
EVENING AND THURSDAY FEATURE AN EXTENSION OF THE CURRENT WEATHER
PATTERN. MOSTLY CLOUDY CONDITIONS WILL PREVAIL AS A FRONT PUSHES
UP AGAINST THE NORTH GULF COAST AND SPREADS MOISTURE INLAND. THE
GULF COAST WILL SEE THE BRUNT OF THESE SYSTEMS WITH STEADIER RAIN
ON WEDNESDAY NIGHT FOLLOWED BY A MORE SHOWERY REGIME THURSDAY INTO
THE WEEKEND. INLAND AREAS AROUND SOUTHCENTRAL WILL ESCAPE THE
STEADY RAIN BUT SOME SHOWERS OR SPRINKLES COULD MAKE IT OVER THE
MOUNTAINS AT TIMES. CLOUD COVER WILL KEEP TEMPERATURES SUPPRESSED,
BUT STILL ABOVE NORMAL FOR LATE APRIL. THE CAVEAT TO THIS IS THAT
ANY BREAKS IN THE CLOUDS, WHICH THERE WILL BE AT TIMES, WILL
QUICKLY BUMP UP THE TEMPERATURES.

THE PATTERN UNSURPRISINGLY LOOKS MUCH THE SAME AS IT HAS ALL
WINTER/SPRING. A CLOSED LOW SOUTH OF THE ALASKA PENINSULA SENDING
WEAKENING FRONTS/DISTURBANCES TOWARD THE MAINLAND. THE LONGWAVE
PATTERN SHIFTS OVER THE WEEKEND AS A PARTICULARLY POTENT
DISTURBANCE RIDES THE JET INTO THE GULF. RAPID CYCLOGENESIS WILL
ENSUE AND ACT TO SHIFT THE WHOLE LONGWAVE TOWARD THE EAST INTO THE
GULF. AT THIS TIME MODELS SUGGEST THIS WILL BE IN THE EASTERN GULF
BUT CONFIDENCE IS PRETTY HIGH THAT IT WILL BE A GULF SYSTEM. IT
LOOKS TO BE FAR ENOUGH TO THE SOUTH/EAST TO GIVE THE MAINLAND SOME
DECENT SPRING DAYS.
