SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
450 AM AKST THU NOV 22 2012

.ANALYSIS AND UPPER LEVELS...

AN UPPER LEVEL RIDGE ACROSS EASTERN SIBERIA AND THE BERING SEA IS
FORMING INTO A CLOSED BLOCKING HIGH...AND IS BEGINNING TO BUILD OVER
PORTIONS OF NORTHWESTERN ALASKA. ACROSS THE SOUTHERN MAINLAND INTO
THE GULF...A SHORTWAVE RIDGE AXIS IS BUILDING ACROSS THE SOUTHEASTERN
PORTION OF INTERIOR ALASKA AS A STRONG STORM IN THE GULF CONTINUES TO
DEEPEN AND LIFT NORTH. ACROSS THE NORTHERN GULF...NUMEROUS WEAK
DISTURBANCES CONTINUE TO SUPPORT BANDS OF LIGHT SNOW SHOWERS OVER
KODIAK ISLAND. THE MAIN STORY...HOWEVER...WILL BE THE STRONG LOW
DEEPENING ACROSS THE GULF OF ALASKA. AS THIS FEATURE LIFTS NORTH
TODAY...THE INCREASING SURFACE PRESSURE GRADIENT WILL BEGIN TO
ACCELERATE DENSE COLD AIR ACROSS THE INTERIOR THROUGH FAVORED GAPS IN
THE TERRAIN. VERY STRONG WINDS WILL DEVELOP BY THIS AFTERNOON AND
WILL LAST THROUGH TONIGHT.

.MODEL DISCUSSION...

ALL THE NUMERICAL MODELS SEEM TO HAVE A VERY GOOD HANDLE ON THE
STRONG GULF OF ALASKA STORM...WITH LITTLE DISCREPANCY ON PLACEMENT OR
STRENGTH. BASED ON SATELLITE SIGNATURE AS OF 1330 UTC THIS
MORNING...THE STORM IS DEVELOPING AS EXPECTED...AND SHOULD REACH PEAK
INTENSITY THIS AFTERNOON. THE NAM WAS FAVORED FOR THIS FORECAST DUE
TO ITS ABILITY TO BETTER SIMULATE THE TIGHT PRESSURE GRADIENT AND
INTENSE GAP WINDS WHICH WILL DEVELOP LATER TODAY.

.SHORT TERM FORECAST...

SOUTHCENTRAL...
THANKSGIVING DAY WILL START RELATIVELY QUIET WITH MAINLY CLEAR AND
COLD CONDITIONS ACROSS THE INTERIOR. HOWEVER...AS THE STRONG LOW IN
THE GULF OF ALASKA APPROACHES THE REGION...THE PRESSURE GRADIENT WILL
RAPIDLY TIGHTEN...WITH AN ASSOCIATED INCREASE IN LOCALIZED CHANNELED
WINDS. ALL THE MAJOR GAP WIND LOCATIONS SUCH AS THE MATANUSKA
VALLEY...VALDEZ...SEWARD...WHITTIER...AND THE COPPER RIVER DELTA WILL
SEE STRONG WINDS BY THIS AFTERNOON. NEAR VALDEZ...HIGH WINDS UP TO 80
MPH WILL DEVELOP ACROSS THOMPSON PASS AND DOWN INTO THE CITY DURING
THE SECOND HALF OF THE DAY...PEAKING DURING THE LATE AFTERNOON AND
EVENING. STRONG GAP WINDS WILL BEGIN TO DIMINISH OVERNIGHT...BUT THEY
WILL REMAIN STRONG THROUGH THE DAY FRIDAY. WIND CHILLS AS LOW AS 35
BELOW ZERO WILL ALSO DEVELOP ACROSS THE HIGHER PASSES THROUGH THE
ALASKA RANGE...INCLUDING BROAD PASS.

NEAR KODIAK ISLAND...NORTHEASTERLY FLOW WILL CONTINUE TO WRAP BANDS
OF SNOW SHOWERS OVER THE ISLAND THIS MORNING...POSSIBLY MIXING WITH
RAIN DURING THE AFTERNOON. MOST SHOWERS...HOWEVER... WILL BEGIN TO
DECREASE BY THIS AFTERNOON...WITH SNOW ACCUMULATIONS OF AN INCH OR
LESS.

SOUTHWEST ALASKA/PENINSULA...
PERSISTENT NORTH TO NORTHEAST FLOW OVER THE REGION WILL CONTINUE
TODAY BEFORE FINALLY SLACKENING FRIDAY AND SATURDAY AS THE BLOCKING
HIGH BEGINS TO EXERT AN INFLUENCE OVER WESTERN ALASKA. COLD
TEMPERATURES AND BRISK WIND CHILLS AS LOW AS 25 BELOW ZERO OVER THE
INTERIOR WILL CONTINUE TO BE THE MAIN STORY...WITH GUSTY NORTHERLY
WINDS AND PERIODIC SNOW SHOWERS OVER THE PENINSULA. SHOWERS AND
NORTHERLY WINDS WILL DIMINISH FRIDAY OVER THE PENINSULA AS HIGH
PRESSURE OVER THE CENTRAL BERING SLIDES EAST.

ALEUTIANS AND BERING SEA...
A COMPACT LOW PRESSURE SYSTEM ACROSS THE WESTERN ALEUTIANS WILL
SUPPORT AREAS OF RAIN AND GALE FORCE WINDS BEFORE TRACKING SOUTH OF
THE CHAIN LATE FRIDAY. FARTHER EAST...MOST OF THE CENTRAL AND EASTERN
ALEUTIANS WILL REMAIN UNDER THE INFLUENCE OF HIGH PRESSURE THROUGH
FRIDAY. A MORE SUBSTANTIAL FRONT WILL TRACK FROM WEST TO EAST ACROSS
THE ALEUTIANS SATURDAY AND SUNDAY...BRINGING MORE RAIN AND GALES TO
THE CHAIN. ACROSS THE CENTRAL AND EASTERN BERING SEA...INCLUDING THE
PRIBILOF ISLANDS...HIGH PRESSURE AND QUIESCENT WEATHER WILL DOMINATE
THROUGH THE WEEKEND.

.LONG TERM FORECAST...
SUNDAY AND BEYOND...THE UPPER LEVEL BLOCKING HIGH WILL SLIDE EASTWARD
OVER THE ALASKA MAINLAND THEN WEAKEN. A LARGE UPPER LOW OVER THE
BERING SEA WILL MERGE WITH ANOTHER LOW SOUTH OF THE ALASKA
PENINSULA...WITH A FEW RAIN AND SNOW SHOWERS IMPACTING THE ALASKA
PENINSULA AND THE GULF COAST INCLUDING KODIAK ISLAND LATE SATURDAY
THROUGH MONDAY. HOWEVER...THE PERSISTENT GLOBAL PATTERN FEATURING A
BLOCKING HIGH OVER GREENLAND...AND ANOTHER OVER THE CENTRAL PACIFIC
AND EASTERN BERING...WILL KEEP MUCH OF INTERIOR ALASKA UNDER THE
INFLUENCE OF COLD HIGH PRESSURE AND GENERAL NORTH TO NORTHEASTERLY
FLOW HEADING INTO MIDWEEK. THIS GENERAL PATTERN WILL CONTINUE TO
RESULT IN THE MOST ACTIVE WEATHER TRACKING ACROSS THE WESTERN BERING
SEA AND THE GULF OF ALASKA.
