SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
500 PM AKDT WED OCT 12 2011

.ANALYSIS AND UPPER LEVELS...
THE UPPER RIDGE OVER WESTERN ALASKA CONTINUES TO MOVE EAST AND IS
WEAKENING THE UPPER TROUGH NEAR THE ALCAN BORDER. MOSTLY CLEAR SKIES
PERSIST OVER SOUTHCENTRAL ALASKA THOUGH THERE ARE ISOLATED SNOW
SHOWERS ALONG THE MOUNTAINS OVER EASTERN COPPER RIVER BASIN. A
MODERATE PRESSURE GRADIENT ALONG THE CHUGACH MOUNTAINS CONTINUES TO
PRODUCE GUSTY WINDS THROUGH CHANNELED TERRAIN OVER PRINCE WILLIAM
SOUND.

ANOTHER UPPER LOW OVER THE NORTHERN BERING IS VERTICALLY STACKED WITH
A STRONG SURFACE LOW AND BOTH ARE MOVING TOWARD THE BERING STRAIT. AN
UPPER SHORT WAVE MOVING EAST THROUGH THE KUSKOKWIM DELTA BROUGHT
RAIN, SNOW AND SOME ISOLATE FREEZING RAIN TO SOUTHWEST ALASKA TODAY.
THE ASSOCIATED WEATHER FRONT OVER THE EASTERN BERING AND THE CENTRAL
ALEUTIANS CONTINUES TO MOVE TOWARD MAINLAND ALASKA. A NEW FRONTAL LOW
IS DEVELOPING SOUTH OF THE WESTERN ALEUTIANS. RAIN AND GUSTY WINDS
FOUND AHEAD OF THE FRONT MOVED INTO THE PRIBILOFS AND CENTRAL
ALEUTIANS THIS MORNING.

.MODEL DISCUSSION...
MODELS CONTINUE TO BE IN GENERALLY GOOD AGREEMENT THOUGH THEY STILL
HAVE SOME DIFFERENCES ON THE WAY THEY HANDLE THE DEVELOPING FRONTAL
LOW SOUTH OF THE ALEUTIANS. THE GFS IS MOVING THE LOW A LITTLE FASTER
THAN EITHER THE ECMWF AND THE NAM MODELS WHILE THE ECMWF MODEL IS A
BIT DEEPER THAN THE OTHER MODELS. NAM APPEARS TO HAVE THE BEST MIDDLE
OF THE ROAD SOLUTION AT THIS TIME.

THE UPPER RIDGE WILL MOVE INTO EASTERN ALASKA THURSDAY MORNING AND
WEAKEN ALONG THE ALCAN BORDER THURSDAY NIGHT. THE UPPER TROUGH OVER
ALONG THE ALCAN BORDER WILL BE PUSHED INTO THE YUKON TERRITORY

ALEUTIANS WILL MOVE ACROSS THE CENTRAL ALEUTIANS THURSDAY MORNING

ISLAND FRIDAY AFTERNOON. THE ASSOCIATED FRONT WILL MOVE INTO THE
ALASKA PENINSULA THURSDAY EVENING AND INTO THE WESTERN GULF FRIDAY

WEST AFTER MIDNIGHT WITH A CHANCE OF RAIN AND SNOW OVER THE KENAI
PENINSULA, SUSITNA VALLEY, MATANUSKA VALLEY AND ANCHORAGE AS THE
REMAINS OF THE WEATHER FRONT MOVES INTO THE AREA THURSDAY. RAIN WILL
MOVE INTO KODIAK ISLAND AND THE SOUTHERN KENAI PENINSULA THURSDAY
EVENING THEN INTO THE SUSITNA VALLEY AND PRINCE WILLIAM SOUND
THURSDAY NIGHT AND FRIDAY. INCREASING SOUTHEAST WINDS OVER THE
NORTHERN GULF AND THROUGH PRINCE WILLIAM SOUND WILL PRODUCE A RAIN
SHADOW OVER ANCHORAGE AND THE MATANUSKA VALLEY THURSDAY NIGHT AND
FRIDAY. STRONG WINDS WILL DEVELOP ALONG TURNAGAIN ARM THURSDAY NIGHT
AND FRIDAY.

.SOUTHWEST ALASKA...RAIN WILL MOVE INTO THE KUSKOKWIM VALLEY AND
BRISTOL BAY WHILE A MIXTURE OF RAIN AND SNOW WILL FALL OVER THE
KUSKOKWIM VALLEY TONIGHT. THE PRECIPITATION WILL BECOME SHOWERS
THURSDAY BUT THE NEXT STORM WILL BRING MORE RAIN TO SOUTHWEST ALASKA
THURSDAY AFTERNOON THROUGH FRIDAY.

.ALEUTIANS AND BERING SEA...RAIN OVER THE CENTRAL ALEUTIANS WILL
SPREAD TO THE EASTERN ALEUTIANS TONIGHT AND THURSDAY BEFORE CHANGING
SHOWERS THURSDAY NIGHT. A SHALLOW SURFACE RIDGE WILL BUILD ACROSS THE
ALEUTIANS AND INTO THE BERING SEA FROM THE WEST THURSDAY AND FRIDAY.
