NWS Anchorage, AK wrote its last area forecast discussion before this small craft advisory went out at Jun 30, 5:00 AM AKDT, 11 hours earlier.

SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
500 AM AKDT THU JUN 30 2011

.ANALYSIS AND UPPER LEVELS...

MASSIVE UPPER LEVEL LOW REMAINS OVER ALL OF MAINLAND AK AND NORTHWEST
CANADA THIS MORNING. EMBEDDED LOWS WITHIN THIS FEATURE ARE OVER THE
NORTHERN AK COAST...THE AKPEN...AND THE SOUTHEASTERN GULF OF AK. A
WEAK UPPER LEVEL RIDGE IS OVER SOUTH CENTRAL. AT THE SURFACE...A LOW
JUST SOUTH OF THE AKPEN IS MOVING INTO THE GULF OF AK...WHILE A
THERMAL TROUGH IS JUST NORTH OF THE AK RANGE. HIGH PRESSURE IS
BUILDING OVER THE BERING SEA.

.MODEL DISCUSSION...

MODELS ARE IN EXCELLENT AGREEMENT FOR THE NEXT SEVERAL DAYS. THE LOW
NEAR THE AKPEN WILL MOVE SLOWLY ACROSS THE GULF. MOVEMENT OF THE
NORTHERN AK UPPER LOW TOWARD THE BERING STRAIT WILL CAUSE THE THERMAL
TROUGH OVER THE INTERIOR TO PUSH SOUTH. THIS WILL PUSH A LOBE OF
MOISTURE RICH AIR TOWARD THE AK RANGE FRI INTO SAT. AN EASTERLY WAVE
WILL MOVE ACROSS THE AREA SOUTH OF THE AK RANGE DURING THE SAME
PERIOD. IN THE WEST...A WEAK RIDGE OF HIGH PRESSURE WILL MOVE OVER
THE BERING AND NORTHWEST FLOW WILL PERSIST OVER WESTERN AK INTO THE
WEEKEND. THE FORECAST UTILIZES THE GFS SOLUTION IN THE SHORT AND
MID-RANGE...TRENDING TO THE HPC SOLUTION NEXT WEEK.

.SHORT TERM FORECAST...

IN THE WEST...SHOWERS WILL PERSIST OVER THE ALEUTIANS THROUGH THE
WEEKEND AS WEAK IMPULSES MOVE ACROSS THE BUILDING RIDGE.

FOR SOUTHWEST AK...RESIDUAL MOISTURE BEHIND THE LOW MOVING ACROSS THE
AKPEN WILL LINGER THROUGH THE WEEKEND...WITH SHOWERS PERSISTING ON
NORTHWEST FLOW.

SOUTH AND EAST OF THE AK RANGE...AS THE THERMAL TROUGH CONTINUES TO
FLIRT WITH THE NORTHERN PORTIONS OF THE AREA...AFTERNOON AND EVENING
SHOWERS WITH ISOLATED THUNDERSTORMS ARE EXPECTED OVER INTERIOR ZONES
TODAY AND FRIDAY WITH MOUNTAIN RANGES AS THE FOCUS OF DEVELOPMENT.
SHOWERS WILL INCREASE IN FREQUENCY AND COVERAGE ON SATURDAY AS THE
EASTERLY WAVE MOVES ACROSS THE AREA. THIS WAVE WILL ALSO TRIGGER MORE
THUNDERSTORMS AWAY FROM THE COAST.

.LONG TERM FORECAST...

A WEAK FRONT MOVING ACROSS THE BERING WILL BRING A FEW SHOWERS TO THE
ALEUTIANS THROUGH MIDWEEK...WHILE SOUTHWEST AK WILL HAVE DRYING
BENEATH A RIDGE. SOUTHEAST OF THE AK RANGE WILL HAVE AFTERNOON AND
EVENING SHOWERS MAINLY NEAR MOUNTAIN RANGES INTO NEXT WEEK.
