SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
423 PM AKDT SUN MAY 10 2015

.ANALYSIS AND UPPER LEVELS...
THE VERTICALLY STACKED LOW OVER THE WESTERN GULF CONTINUES TO
SLOWLY WEAKEN AND MEANDER NORTH. SCATTERED TO NUMEROUS RAIN
SHOWERS OVER THE WESTERN GULF COAST AND PRINCE WILLIAM SOUND ARE
CONTINUING AS SHORTWAVES CONTINUE TO MOVE INLAND. OVER THE
ALEUTIANS...AN ELONGATED LOW STRETCHING FROM THE EASTERN BERING
INTO THE EASTERN ALEUTIANS AND SOUTHERN AKPEN IS BRINGING GUSTY
RAIN AND SOME WIND. THIS SYSTEM IS TRACKING TO THE EAST TOWARDS
THE GULF WHERE IT WILL ABSORB THE GULF LOW LATE TONIGHT.

&&

.MODEL DISCUSSION...
THE MODELS REMAIN IN VERY GOOD AGREEMENT WITH THE DEVELOPING LOW
SOUTH OF THE AKPEN THROUGH MONDAY...WITH JUST SOME MINOR
DISAGREEMENT WITH LOW POSITION AND INTENSITY THAT SHOULD HAVE
MINIMAL IMPACT ON THE OVERALL FORECAST CONFIDENCE. ON
TUESDAY...LARGER DISCREPANCIES ARISE WITH THE STRENGTH OF THE NEXT
NORTH PACIFIC LOW THAT WILL APPROACH THE WESTERN ALEUTIANS. THE
MODELS ARE ALL TRENDING STRONGER...WITH GOOD AGREEMENT THAT THIS
WILL BE AT LEAST GALE FORCE LOW...BUT THE GFS HAS BEEN
CONSISTENTLY STRONGER WITH THIS LOW. THE EC AND GEM GLOBAL MODELS
WERE PREFERRED WITH THIS NEXT LOW...KEEPING WINDS A BIT WEAKER
THAN THE STRONGER GFS SOLUTION.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (DAYS 1 AND 2)...
THE UPPER LEVEL LOW IN THE GULF OF ALASKA WILL CONTINUE TO DRIFT
NORTH TO BE CENTERED OVER THE NORTHERN GULF AND KENAI PENINSULA
TONIGHT. THE COOL AIR ALOFT ASSOCIATED WITH THIS LOW WILL KEEP
SHOWERS GOING ALONG THE GULF COAST AS WELL AS KEEPING THE
ATMOSPHERE UNSTABLE AND ALLOWING FOR ISOLATED TO SCATTERED
SHOWERS INLAND IN THE AFTERNOONS AND EVENINGS ESPECIALLY OVER THE
HIGHER TERRAIN. A SHORTWAVE TROUGH ROTATING INLAND OVER THE
EASTERN GULF COAST AND COPPER RIVER BASIN WILL ALSO GIVE A BOOST
TO SHOWER ACTIVITY IN THOSE AREAS MONDAY WITH FAIRLY LOW SNOW
LEVELS.

ALSO ON MONDAY THE NEXT SURFACE LOW WILL TRACK ACROSS THE FAR SOUTHERN
GULF. AN ASSOCIATED SURFACE FRONT WILL LIFT FURTHER NORTH INTO THE
CENTRAL GULF BUT ASIDE FROM BRINGING SOME SMALL CRAFT LEVEL EAST
TO NORTHEASTERLIES AND RAIN TO THE WATERS THIS SYSTEM SHOULD HAVE
MINIMAL IMPACT ON SOUTH CENTRAL ALASKA. THIS LOW WILL WEAKEN AND
SLIDE TO THE SOUTHEAST MONDAY NIGHT AND TUESDAY MARKING THE
BEGINNING OF A WARMING TREND.

&&

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

A WEAKENING FRONT OVER THE EASTERN BERING IS SUPPORTING GUSTY
SOUTHEAST WINDS ACROSS MOST OF THE REGION THIS EVENING...BUT THESE
WILL DIMINISH HEADING THROUGH THE NIGHT AS THE FRONT CONTINUES TO
WEAKEN AND TEMPERATURES FALL. THE FRONT WILL MOVE INLAND MONDAY
ACROSS THE KUSKOKWIM DELTA COAST...WITH RAIN AND RAIN SHOWERS
IMPACTING THE AREA. ISOLATED TO SCATTERED AFTERNOON AND EVENING
SHOWERS WILL FORM ALONG THE HIGHER TERRAIN OF THE MOUNTAINS...WITH
A FEW OF THOSE SHOWERS MOVING INTO LOWER ELEVATION INLAND AREAS.
THE REGION WILL STABILIZE AND DRY OUT ON TUESDAY...WITH SHOWERS
BEING RELEGATED TO THE ALASKA RANGE.

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

A STALLED FRONT OVER THE EASTERN BERING WILL CONTINUE TO BRING
RAIN AND RAIN SHOWERS OVER THE EASTERN BERING AND
ALEUTIANS...WHILE A SECONDARY LOW TRACKS INTO THE CENTRAL
ALEUTIANS TONIGHT. BOTH OF THESE FEATURES WILL WEAKEN BEFORE A
STRONGER AND MUCH LARGER GALE FORCE LOW MOVES INTO THE WESTERN
BERING MONDAY AFTERNOON...WITH THE ASSOCIATED FRONT TRACKING
RAPIDLY INTO THE EASTERN BERING AND ALEUTIANS BY TUESDAY
AFTERNOON. WIDESPREAD RAIN WILL IMPACT THE WHOLE REGION AS THIS
MOIST FRONT MAKES NORTHEAST PROGRESSION.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...
A RIDGE OF HIGH PRESSURE WILL BUILD OVER THE SOUTHWEST MAINLAND
AND GULF FROM THE WEST TUESDAY AFTERNOON...AND CONTINUE TO AMPLIFY
AS IT SETS UP OVER SOUTHCENTRAL WEDNESDAY. SOME GUSTY GAP WINDS
ARE EXPECTED TO DEVELOP AS THE GRADIENT TIGHTENS UP OVER WESTERN
PRINCE WILLIAM SOUND AND TURNAGAIN ARM...AS WELL AS SOME WARMER
TEMPERATURES ADVECTING UP FROM THE NORTHERN PACIFIC WHICH WILL
PERSIST THROUGH THE BEGINNING OF THE WEEKEND. RAINY AND WINDY
CONDITIONS ARE EXPECTED TO TRACK INTO THE SOUTHWEST MAINLAND AND
GULF WEDNESDAY...AS A FRONTAL SYSTEM ASSOCIATED WITH A NORTH
PACIFIC LOW NEAR THE WESTERN ALEUTIANS TRACKS THROUGH THE AREA.
THE FRONT WILL THEN WEAKEN AND PUSH INTO SOUTHCENTRAL WEDNESDAY
EVENING...WHERE THE RAINY AND GUSTY CONDITIONS WILL PERSIST
THROUGH EARLY THURSDAY MORNING BEFORE BRIEFLY TAPERING OFF.
MODELS ARE NOW INDICATING THAT THE ABOVE MENTIONED NORTH PACIFIC
LOW OVER THE WESTERN ALEUTIANS WILL BEGIN TO WEAKEN AND TRANSFER
ENERGY TO A TRIPLE POINT LOW FORMING SOUTH OF THE CENTRAL
ALEUTIANS WEDNESDAY AFTERNOON. THE FRONTAL SYSTEM ASSOCIATED WITH
THIS TRIPLE POINT LOW WILL INITIALLY BRING SOME GUSTY AND SHOWERY
CONDITIONS TO THE FAR EASTERN ALEUTIANS AND ALASKA PENINSULA
THURSDAY...WHERE OTHERWISE BROAD CYCLONIC FLOW OVER THE REMAINDER
OF THE ALEUTIANS/BERING WILL KEEP SOME SHOWERY CONDITIONS OVER THE
AREA THROUGH THE END OF THE WEEK. THE FRONTAL SYSTEM WILL THEN
QUICKLY CATCH UP TO THE WEAKENING FRONTAL SYSTEM OVER THE GULF
THURSDAY EVENING...REINFORCING THE GUSTY WINDS AND RAINY
CONDITIONS OVER SOUTHCENTRAL THROUGH THE BEGINNING OF THE WEEKEND.
MODELS THEN SHOW THE TRIPLE POINT LOW TRACKING NORTHWARD INTO THE
BRISTOL BAY/EASTERN BERING REGION BY FRIDAY AFTERNOON...WHICH
COULD KEEP SOME OF THE WET AND WINDY CONDITIONS OVER THE ALASKA
PENINSULA AND SOUTHWEST MAINLAND INTO THE WEEKEND. HOWEVER THERE
ARE STILL SOME TIMING AND STRENGTH DISCREPANCIES IN THE MODELS
REGARDING THIS SYSTEM...KEEPING FORECAST CONFIDENCE SLIGHTLY BELOW
AVERAGE.
