NWS Anchorage, AK wrote its last area forecast discussion before this small craft advisory went out at May 31, 1:00 PM AKDT, 3 hours earlier.

SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
100 PM AKDT THU MAY 31 2012

.MODEL DISCUSSION...GFS AND NAM IN GOOD AGREEMENT ON SOLUTION IN THE
GULF BUT GFS RUNNING DEEPER ON WESTERN ALEUTIAN SYSTEM THAT MOVES
INTO THE PICTURE FRI AFTERNOON. WILL USE GFS SOLUTION FOR SYNOPSIS.

GULF LOW JUST OFF OF KODIAK WILL CONTINUE TO SPIN THROUGH SAT BUT
WILL MOVE INTO THE SOUTHERN GULF BY SAT MORNING. FRONT ALONG THE
COAST THIS AFTERNOON WILL DISSIPATE OVER NIGHT. WEAKER EAST FLOW ON
FRI SHOULD ALLOW CONSIDERABLE SUNSHINE OVER MUCH OF SOUTHCENTRAL. A
SERIES OF FRONTS WILL MOVE THROUGH THE WESTERN ALEUTIANS OVER THE
NEXT SEVERAL DAYS WITH SOUTHWEST FLOW.

.ANALYSIS AND UPPER LEVELS...FRONT ALONG GULF COAST IS CHANGING OVER
TO SHOWERS AND WILL WEAKEN OVER NIGHT. MODEST EAST WINDS IN THE SAME
AREA WILL DISSIPATE BY MIDNIGHT TONIGHT. RIDGE IN BERING GENERATING
CONSIDERABLE STRATUS AND FOG. NORTH TO NORTHWEST FLOW OVER THE
EASTERN BERING WILL CONTINUE THROUGH FRI AFTERNOON. EXPECTING THERMAL
TROUGH TO FORM IN THE INTERIOR THROUGH THE FORECAST PERIOD.

.SHORT TERM FORECAST...
BERING REGION...CLOUDS AND FOG. NORTH WINDS EASTERN AL AND AK PEN
THROUGH FRI NIGHT. FRONT MOVING INTO WESTERN AL THIS AFTERNOON.

SOUTHWEST ZONES...GENERALLY NORTH FLOW ALOFT WEAKENING TONIGHT. MIX
OF CLOUDS AND CLEAR AREAS WITH HIGHEST INSTABILITY AND POTENTIAL
T-STORMS ALONG KUSKO MOUNTAINS THU AFTERNOON AND FRI AFTERNOON.

SOUTHCENTRAL...RAIN TURNING TO SHOWERS ALONG THE COAST THIS EVENING
WITH MID-LEVEL CLOUDS INLAND. ISOLATED SHOWERS THIS AFTERNOON AND
EVENING INLAND. MORE SUN ON FRI AND SAT AS GULF LOW WEAKENS AND
EASTERLY FLOW DIMINISHES.

KODIAK...MORE RAIN BUT TURNING TO SHOWERS ON FRI.

.LONG TERM FORECAST...NO CHANGES FROM PREVIOUS THOUGHTS...A SERIES OF
FRONTS MOVING THROUGH THE WESTERN AND BERING SEA SLOWLY WORKING INTO
THE EASTERN AL EARLY NEXT WEAK.  HIGH PRESSURE BUILDING OVER THE GULF
ON SUN ONWARD.  THERMAL THROUGH OVER THE INTERIOR FOR MOST OF THE
PERIOD.  SHOULD SEE FAIRLY CONSISTENT SUNSHINE OVER MOST OF THE
MAINLAND WITH CHANCE FOR AFTERNOON/EVENING SHOWERS ON MOST DAYS. NO
MAJOR WEATHER SYSTEMS IN REGION FOR FORESEEABLE FUTURE.
