SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
620 AM AKDT SUN SEP 15 2013

.ANALYSIS AND UPPER LEVELS...
AN UPPER LOW CONTINUES TO PROGRESS SLOWLY EASTWARD ACROSS THE FAR
SOUTHERN GULF THIS MORNING...WITH ASSOCIATED SHOWERS GENERALLY
CONFINED TO MARINE AREAS. AN UPPER LEVEL RIDGE PUSHING SLOWLY
EASTWARD ACROSS THE BRISTOL BAY REGION IS SUPPORTING QUIET CONDITIONS
FROM THE EASTERN BERING SEA TO THE SOUTHERN MAINLAND. ANOTHER UPPER
LOW PUSHING INTO THE NORTHERN BERING FROM EASTERN RUSSIA IS BRINGING
SHOWERS TO THE CENTRAL BERING. CLEARING SKIES ALONG WITH RESIDUAL LOW
LEVEL MOISTURE FROM RECENT RAINFALL HAS ALLOWED AREAS OF FOG TO
DEVELOP OVER PORTIONS OF SOUTHCENTRAL ALASKA. CLEARING HAS ALSO
RESULTED IN COLD MORNING LOW TEMPERATURES OVER SEVERAL AREAS...WITH
TEMPERATURES FALLING INTO THE 30S OVER THE MAT-SU VALLEY AND COPPER
RIVER BASIN AS WELL AS EAST ANCHORAGE.

.MODEL DISCUSSION...
MODELS REMAIN IN GENERALLY GOOD AGREEMENT THROUGH THE FIRST PART OF
THE SHORT TERM BUT LARGER DIFFERENCES BEGIN TO ARISE BY TUESDAY.
MODELS CONTINUE TO STRUGGLE IN HANDLING THE EVOLUTION OF THE COMPLEX
SURFACE LOW OVER THE GULF EARLY IN THE WEEK AS THE UPPER LOW MOVES
EASTWARD AND BEGINS TO RECURVE TOWARDS THE NORTHERN GULF. CONTINUED
TO UTILIZE THE EC AS IT HAS BEEN THE MOST CONSISTENT REGARDING THIS
FEATURE.

.SHORT TERM FORECAST...
SOUTHCENTRAL ALASKA...
MOST OF THE AREA LOOKS TO REMAIN DRY WITH ABUNDANT SUNSHINE THROUGH
THE DAY ON MONDAY AS THE GULF LOW MOVES TOWARD THE PANHANDLE. GIVEN
MOSTLY CLEAR SKIES...THE PRIMARY FORECAST CONCERNS WILL CONTINUE TO
BE MORNING FOG DEVELOPMENT AND THE POTENTIAL FOR OVERNIGHT LOW
TEMPERATURES TO DIP BELOW FREEZING IN FAVORED AREAS WHERE RADIATIONAL
COOLING IS MAXIMIZED. A FREEZE WARNING REMAINS IN EFFECT THROUGH
MONDAY MORNING FOR EAST ANCHORAGE AND THE MATANUSKA VALLEY TO ACCOUNT
FOR THESE CONCERNS. A CHANCE FOR PRECIPITATION WILL RETURN TO
SOUTHCENTRAL AK ON TUESDAY AS THE LOW MOVES BACK OVER THE NORTHERN
GULF.

SOUTHWEST ALASKA...
SUNNY SKIES WILL PREVAIL OVER MUCH OF THE SOUTHWEST MAINLAND TODAY AS
UPPER LEVEL RIDGING REMAINS OVERHEAD. A CHANCE FOR PRECIPITATION WILL
RETURN LATE TONIGHT INTO MONDAY AS THE UPPER LOW OVER THE NORTHERN
BERING SLIDES SOUTHEASTWARD ALONG THE COAST.

ALEUTIANS/BERING SEA...
THE UPPER LOW MOVING ACROSS THE NORTHERN BERING WILL SPREAD RAIN OVER
THE CENTRAL BERING AND THE PRIBILOF ISLANDS THROUGH TONIGHT...WITH A
FEW SHOWERS POSSIBLE BY TONIGHT OVER THE CENTRAL AND EASTERN
ALEUTIANS. UPPER LEVEL RIDGING WILL THEN BUILD IN BEHIND THE
LOW...RESULTING IN THE USUAL LOW STRATUS AND FOG. A FRONT ASSOCIATED
WITH A STRONG LOW NEAR THE KAMCHATKA PENINSULA WILL MOVE OVER THE
WESTERN BERING ON MONDAY...BRINGING RAIN AND GAIL FORCE WINDS TO THE
WESTERN ALEUTIANS.

.LONG TERM FORECAST...
A WETTER PATTERN WILL RETURN TO THE SOUTHERN MAINLAND BY THE MIDDLE
OF THE WEEK AS THE LOW OVER THE NORTHERN BERING SLIDES SOUTHEASTWARD
INTO THE GULF. TEMPERATURES LOOK TO BE TRENDING MUCH COOLER BY THE
MIDDLE OF THE WEEK AS ANOTHER UPPER LOW DROPS SOUTHWARD TOWARDS THE
AREA FROM THE ARCTIC COAST.
