SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
500 AM AKST MON DEC 12 2011

.ANALYSIS AND UPPER LEVELS...
AN INTENSE LOW PRESSURE SYSTEM IS MOVING INLAND AND DISSIPATING OVER
PRINCE WILLIAM SOUND. HOWEVER...EVEN AS IT WEAKENS IT CONTINUES TO
IMPACT WEATHER ACROSS THE SOUTHCENTRAL REGION. STEADY SNOW HAS BEEN
FALLING EARLY THIS MORNING ACROSS THE ANCHORAGE BOWL AND KENAI
PENINSULA WITH SOME RAIN MIXED IN ACROSS THE MATANUSKA VALLEY.
MEANWHILE...THE NEXT IMPORTANT LOW IS IN THE NORTH PACIFIC SOUTH OF
ADAK AND EXPECTED TO INTENSIFY INTO THE 951 MB. AN IMPRESSIVE RIDGE
BETWEEN THESE TWO FEATURES IS SUPPORTING QUIET CONDITIONS ACROSS MUCH
OF THE SOUTHWEST MAINLAND ALASKA THIS MORNING.

.MODEL DISCUSSION...
MODELS ARE IN DECENT AGREEMENT ON THE NEXT INTENSE LOW PRESSURE
SYSTEM THAT WILL APPROACH THE CENTRAL ALEUTIANS BY MONDAY AFTERNOON.
HOWEVER...THERE IS STILL ENOUGH UNCERTAINTY IN HOW FAR EAST THE LOW
WILL TRACK. THIS RESULTS IN UNCERTAINTY IN WIND GUST POTENTIAL IN
DUTCH HARBOR MONDAY EVENING INTO TUESDAY. MODELS ALSO DISAGREE ON THE
PROPAGATION OF A FRONT THAT APPROACHES THE WEST GULF OF ALASKA BY
EARLY WEDNESDAY MORNING. HOWEVER...MODELS APPEAR TO BE IN MUCH BETTER
AGREEMENT THAN THEY HAVE BEEN FOR THE PAST FEW DAYS.

.SHORT TERM FORECAST...
.SOUTHCENTRAL ALASKA...STEADY SNOW IS FALLING ACROSS MUCH OF THE
SOUTHCENTRAL REGION THIS MORNING. AS THIS LOW
DISSIPATES...DOWNSLOPING WINDS WILL CONTINUE TO SUBSIDE. AS A
RESULT...SNOW IS EXPECTED TO FALL ACROSS THE ANCHORAGE BOWL AND
MATANUSKA VALLEY THROUGH THE MORNING PERIOD. CONDITIONS WILL THEN BE
RELATIVELY QUIET THROUGH TUESDAY AS HIGH PRESSURE BUILDS IN. A FRONT
WILL THEN BEGIN TO SWEEP ACROSS THE GULF FROM WEST TO EAST BEGINNING
TUESDAY NIGHT.

.SOUTHWEST ALASKA...CONDITIONS HAVE REMAINED RELATIVELY QUIET ACROSS
MUCH OF THE SOUTHWEST MAINLAND EARLY THIS MORNING WITH HIGH PRESSURE
BUILDING IN. WEAK UPPER LEVEL WAVES HAVE SUPPORTED A FEW STRAY
SHOWERS NEAR BETHEL AND ALONG THE ALASKA PENINSULA. HOWEVER...GUSTY
WINDS AND RAIN WILL RETURN TO THE SOUTHWEST MAINLAND BY TUESDAY
MORNING AS A FRONT APPROACHES THE ALASKA PENINSULA AND THEN BERING
COAST.

.BERING SEA AND ALEUTIANS...LIGHT COLD AIR ADVECTION SHOWERS
CURRENTLY DOMINATE THE BERING SEA WITH GENERALLY LIGHT WINDS ACROSS
THE REGION.  HOWEVER...CLOUDS ASSOCIATED WITH THE NEXT STRONG LOW
PRESSURE SYSTEM ARE ALREADY PUSHING INTO THE CENTRAL ALEUTIANS.  A
954 MB LOW IS EXPECTED TO BE OVER ADAK BY THIS EVENING. STRONG WINDS
WILL REACH MUCH OF THE ALEUTIANS BY THIS EVENING...WITH THE BRUNT OF
THE WINDS IMPACTING THE CENTRAL ALEUTIANS.

.LONG TERM FORECAST...
A STRONG JET STREAM WILL CONTINUE TO UNDULATE ACROSS THE NORTH
PACIFIC OVER THE NEXT WEEK. AS A RESULT...STRONG LOW PRESSURE SYSTEMS
WILL CONTINUE TO DEVELOP AND MOVE ACROSS THE BERING.
