SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
419 PM AKDT TUE APR 19 2016

.ANALYSIS AND UPPER LEVELS...

THE PERSISTENT LONGWAVE TROUGH REMAINS IN PLACE OVER THE BERING
SEA WITH GENERAL RIDGING EXTENDING NORTHWARD ALONG THE CONTINENTAL
WEST COAST AND UP INTO MAINLAND ALASKA. THIS IS SETTING THE STAGE
FOR THE MAJORITY OF THE STATE TO SEE CONTINUED SOUTHEAST FLOW. A
WEATHER FRONT OVER THE SOUTHWEST MAINLAND AND KODIAK ISLAND IS
SLOWLY MAKING NORTHWARD PROGRESS BUT WILL BE STALLING TONIGHT.
GUSTY SOUTHEAST WINDS AND INCREASED CLOUD COVER FROM BRISTOL BAY TO
THE KUSKOKWIM DELTA AND INTO MOST OF THE COOK INLET AREA ARE THE
MAIN IMPACTS FROM THIS FRONT AS THE COASTAL MOUNTAINS ARE KNOCKING
OUT MOST OF THE PRECIPITATION IN THE TYPICAL UPSLOPE AREAS.
MEANWHILE...A SHORTWAVE TROUGH IS MAKING A NEAR- APPROACH TO THE
COASTLINE OF THE SOUTHWEST MAINLAND AND IS HELPING TO PRODUCE A
LITTLE MORE IN THE WAY OF RAIN IN THAT AREA...THOUGH EVEN THIS
WILL BE ON THE DECLINE BY TONIGHT.

FURTHER WEST...BROAD CYCLONIC FLOW AND WEAK THERMAL ADVECTION DOMINATE
ACROSS THE BERING SEA. SO WHILE CLOUDINESS AND GENERALLY UNSETTLED
WEATHER ARE WIDESPREAD THE WEATHER PATTERN AS A WHOLE IS FAIRLY
BENIGN FOR THIS PART OF THE WORLD.

&&

.MODEL DISCUSSION...

THE MODELS ARE IN GOOD OVERALL AGREEMENT...AND ALL DEPICT NO
FUNDAMENTAL PATTERN SHIFTS IN THE NEAR FUTURE. A 175 KT JET STREAK
WILL CARRY A SHORTWAVE AROUND THE BASE OF THE LONGWAVE TROUGH
TONIGHT AND WILL RESULT IN A NEW LOW SPINNING UP SOUTH OF THE
ALASKA PENINSULA TONIGHT AND TOMORROW. THERE IS A PIECE OF ENERGY
THAT SPLITS OFF FROM THIS FEATURE AND RACES NORTHWARD INTO THE
LONGWAVE TROUGH. WHILE THERE IS VERY LITTLE UPPER LEVEL SUPPORT
FOR THIS FEATURE ALL MODELS DO DEPICT A SURFACE LOW SPINNING UP
AND CROSSING THE ALASKA PENINSULA. THE NAM/GFS ARE MORE AGGRESSIVE
MOVING THIS REMNANT LOW UP TOWARD THE PRIBILOF ISLANDS TOMORROW
AFTERNOON...WHILE THE ECMWF IS WEAKER AND SLOWER. GIVEN THE WEAK
UPPER LEVEL SUPPORT THE WEAKER ECMWF/GEM SOLUTIONS ARE FAVORED BY
THE WESTERN DOMAIN FOR THE AFTERNOON FORECAST. THE MAIN IMPACT
FROM THIS MODEL DISCREPANCY WILL BE TO PROLONG THE GUSTY WINDS IN
THE PRIBILOFS.

&&

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

GUSTY WINDS WILL BE REACHING PEAK INTENSITY THROUGH GAPS ALONG
TURNAGAIN ARM...PORTAGE VALLEY...THE KNIK RIVER VALLEY AND COPPER
RIVER THIS AFTERNOON/EVENING BEFORE PRESSURE GRADIENTS ACROSS THE
REGION BEGIN TO WEAKEN. HIGH PRESSURE WILL RESIDE OVER SOUTHCENTRAL
ALASKA THROUGH THURSDAY AFTERNOON WHICH WILL KEEP MUCH OF THE
REGION ON THE DRY SIDE. THIS HIGH PRESSURE WILL SUPPRESS DIURNAL
CONVECTION AS IT HELPS STABILIZE THE MID-LEVELS BY GRADUALLY
WARMING THE MID-LEVEL THERMAL PROFILE. THIS HAS BEEN OBSERVED ON
THE PAST 3 RAOB SOUNDING FROM PANC. SOME BREAKS IN CLOUD COVER
WILL BE OBSERVED ON THURSDAY WITH DECENT SUBSIDENCE FOLLOWING IN
THE WAKE OF A WEAK UPPER LEVEL SHORTWAVE. IN THE MEANTIME...A
FRONTAL BOUNDARY CONTINUES TO MAKE VERY SLOW PROGRESS OVER KODIAK
ISLAND. RAIN WILL CONTINUE TO OVERSPREAD THE EASTERN KENAI
PENINSULA TONIGHT AS THE FRONT SLOWLY PUSHES EASTWARD BUT RAIN
CHANCES WILL DIMINISH WEDNESDAY AFTERNOON AS THE FRONT RETREATS TO
THE WEST.

&&

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

STALLED REMNANTS OF A WEATHER FRONT PERSIST ACROSS SOUTHWEST
ALASKA...AND WILL BRING RAIN MAINLY TO UPSLOPE AND INLAND AREAS
OF BRISTOL BAY AND WINDY CONDITIONS THROUGH MUCH OF SOUTHWEST
ALASKA...THROUGH EARLY WEDNESDAY. HIGH PRESSURE BUILDING TO THE
NORTH AND EAST WILL HELP PUSH THIS FRONT TOWARD THE COAST
WEDNESDAY NIGHT AND THURSDAY...BRINGING A CLEARING AND DRYING
TREND WITH LESS WIND ESPECIALLY TO INLAND AREAS.

&&

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

WITH BROAD LOW PRESSURE OVER THE BERING THE GENERAL FLOW PATTERN
WILL BE CYCLONIC WITH WESTERLY WINDS OVER MUCH OF THE
ALEUTIANS...SOUTHEASTERLY FLOW OVER THE ALASKA PENINSULA AND
EASTERLY WINDS OVER THE NORTHERN BERING...WITH A FAIRLY STRONG YET
STATIONARY WEATHER FRONT DELINEATING THE BOUNDARY BETWEEN THE
WESTERLY WINDS AND EAST TO SOUTHEASTERLY WINDS. THE STRONGEST
WINDS WILL BE OUT EAST WHERE THE MAJORITY OF THE UPPER LEVEL
SUPPORT WILL BE. THIS PATTERN WILL BE VERY STAGNANT WITH
WIDESPREAD RAINY CONDITIONS EXPECTED FOR THE SOUTHERN ALASKA
PENINSULA AND PRIBILOF ISLANDS THROUGH THE NEXT FEW DAYS.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...
MEDIUM RANGE GUIDANCE PAINTS A SIMILAR PICTURE OF THE LONG-WAVE
PATTERN WITH A PERSISTENT TROUGH ACROSS THE NORTH PACIFIC/ALEUTIANS
OVER INTO THE GULF OF ALASKA WITH RIDGING FROM WESTERN CANADA
INTO THE NORTHERN MAINLAND OF ALASKA. HOWEVER THERE ARE SIGNIFICANT
DIFFERENCES IN HANDLING OF INDIVIDUAL FEATURES EMBEDDED WITHIN THE
LONG-WAVE TROUGH. THUS...FORECAST CONFIDENCE STARTS OUT ABOUT
AVERAGE AND QUICKLY FALLS TO LOW.

ONE NOTABLE COMMONALITY IN ALL THE SOLUTIONS IS FOR A SERIES OF
ROBUST LOWS/SHORT-WAVES TO PUSH THE RIDGE A BIT FURTHER NORTH AND
EAST THIS WEEKEND. THIS WILL BRING SIGNIFICANT CLOUD COVER TO THE
SOUTHERN MAINLAND AND THE LIKELIHOOD OF SEEING RAIN ACROSS MUCH
OF THE REGION. A CONTINUATION OF GENERALLY SOUTHEAST FLOW WILL
STILL LEAD TO LOCALIZED DRYING ON THE NORTH TO WEST SIDE OF
MOUNTAIN RANGES...BUT EXPECT A CHANCE OF RAIN IN THESE AREAS
AS FEATURES MOVE THROUGH. DESPITE THE INCREASE IN CLOUD COVER...
THIS GENERAL FLOW WILL MAINTAIN WELL ABOVE NORMAL TEMPS ACROSS
SOUTHCENTRAL AND SOUTHWEST ALASKA.
