SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
200 PM AKDT WED AUG 31 2011

.MODEL DISCUSSION...

MODELS ARE IN GOOD AGREEMENT THROUGH THE SHORT TERM. THE EUROPEAN
(EC) MODEL SEEMS TO HAVE SCORED THE COUP IN SHOWING A PHASING
SOLUTION WITH LOW PRESSURE APPROACHING THE GULF OF ALASKA FROM THE
SOUTHWEST ON FRIDAY...AS THE OTHER MODELS HAVE NOW COME IN LINE WITH
ITS SOLUTION. THE RESULT WILL BE A STRONGER LOW IN THE GULF OF ALASKA
FRIDAY WITH A LARGE SWATH OF GALE FORCE WINDS AND THE POSSIBLE
DEVELOPMENT OF A FAIRLY STRONG BARRIER JET ALONG THE NORTH GULF
COAST.

.ANALYSIS AND UPPER LEVELS...

A LARGE NEGATIVELY TILTED TROUGH RESIDES FROM SOUTHWEST ALASKA SOUTH
AND EAST INTO THE NORTHWEST GULF OF ALASKA...WITH A WEAK SURFACE LOW
HAVING DEVELOPED THIS MORNING IN THE NORTHERN GULF AND MOVING EAST
TOWARDS THE PANHANDLE THROUGH TONIGHT. AS THE TROUGH SPLITS AND THE
FLOW ALOFT BECOMES MORE NORTHERLY ON THE BACKSIDE...WE SHOULD START
TO SEE THE RAIN COME TO END GRADUALLY THIS EVENING. A RAPIDLY MOVING
TRANSITORY RIDGE PASSES OVER SOUTHCENTRAL ALASKA THURSDAY...BEFORE
THE NEXT SYSTEM (THE AFOREMENTIONED PHASING SOLUTION) GETS GOING IN
THE GULF OF ALASKA LATE THURSDAY NIGHT THROUGH FRIDAY. THIS LOW
PRESSURE SYSTEM SLOWLY WEAKENS INTO SATURDAY IN THE GULF WHILE YET
ANOTHER SYSTEM DROPS SOUTH AND EAST INTO THE NORTHERN BERING FROM
EASTERN SIBERIA.

.SHORT TERM FORECAST...

SOUTHCENTRAL ALASKA...

DEVELOPING LOW PRESSURE IN THE NORTHERN GULF HAS HELPED INITIATE A
BARRIER JET ALONG THE NORTH GULF COAST INTO PRINCE WILLIAM SOUND THIS
MORNING. EXPECT THESE WINDS TO DIMINISH RAPIDLY THIS EVENING AND TURN
NORTHWESTERLY AS THE SURFACE LOW MOVES RAPIDLY TOWARDS THE PANHANDLE.
STRONG NORTHWESTERLY FLOW ON THE BACK SIDE OF THE LOW WILL BRING A
LARGE AREA OF GALES FROM THE BARREN ISLAND WATERS THROUGH THE WESTERN
OFFSHORE ZONES TONIGHT. OVER THE SOUTHCENTRAL MAINLAND...RAIN WILL
TAPER TO SCATTERED SHOWERS ACROSS THE COOK INLET AND SUSITNA VALLEY
REGIONS THIS EVENING...WITH PARTIAL CLEARING OCCURRING TOWARDS
MORNING.

AFTER A TRANQUIL DAY OF PARTLY SUNNY SKIES OVER THE REGION ON
THURSDAY...THE NEXT SYSTEM BEGINS TO AFFECT THE REGION LATE THURSDAY
NIGHT THROUGH FRIDAY WITH RAIN ALONG THE COAST...AND SCATTERED
SHOWERS INLAND. STRONG GALES WILL BE POSSIBLE ALONG THE NORTHERN GULF
WITH THE POSSIBLE DEVELOPMENT OF A BARRIER JET.

SOUTHWEST ALASKA...

SHOWERS WILL TAPER OFF THROUGH THIS EVENING...WITH A BRIEF PERIOD OF
TRANQUIL WEATHER BEFORE THE NEXT SYSTEM MOVES ONSHORE IN THE DELTA
REGION BY MIDNIGHT AND THEN MOVES EAST ACROSS THE REGION BEFORE
TAPERING OFF FRIDAY EVENING.

BERING SEA/ALEUTIANS...

LOW PRESSURE IS ENTERING THE NORTHERN BERING THIS AFTERNOON AND IS
PUSHING A GALE FORCE FRONT ACROSS THE BERING THROUGH TONIGHT. HIGH
PRESSURE SWIFTLY MOVES ACROSS THE BERING FRIDAY AS ANOTHER WEATHER
FRONT MOVES INTO THE WESTERN BERING FRIDAY NIGHT.

.LONG TERM FORECAST...

GLOBAL MODELS CONTINUE TO HINT AT THE FAST ZONAL PATTERN OF THIS WEEK
EVOLVING INTO A MUCH MORE HIGHLY AMPLIFIED WEATHER PATTERN BY EARLY
NEXT WEEK. THOUGH THERE ARE DIFFERENCES IN HOW THIS EVOLUTION COMES
ABOUT...THE RESULT APPEARS TO BE A LARGE AND STRONG LOW PRESSURE
DEVELOPING NEAR OR SOUTH OF THE ALASKA PENINSULA AND EVENTUALLY
MOVING TOWARDS THE GULF OF ALASKA. THIS WOULD RESULT IN STRONG WINDS
TO AT LEAST GALE FORCE OVER A LARGE PORTION OF THE GULF THE EARLY OR
MIDDLE PART OF NEXT WEEK...WHILE HIGH PRESSURE RIDGES BUILD TO THE
NORTH FROM THE WESTERN BERING ACROSS TO WESTERN NORTH AMERICA.
