SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
500 PM AKST SAT MAR 5 2011

.MODEL DISCUSSION...
THE MODELS ARE IN VERY GOOD AGREEMENT OVER MAINLAND ALASKA AND THE
GULF THROUGH MONDAY NIGHT BUT THEY ARE STILL HAVING PROBLEMS COMING
TO A COMMON SOLUTION FOR THE STORM SYSTEM APPROACHING THE ALEUTIANS
AND HOW IT WILL EVOLVE OVER THE NEXT FEW DAYS. THE GFS IS THE
PREFERRED MODEL IN THE WEST BECAUSE IT HAS ALL OF THE FEATURES COMMON
TO MOST OF THE MODELS. THE NAM IS USED IN THE GULF AND MAINLAND
ALASKA.

.ANALYSIS AND UPPER LEVELS...
THE UPPER LOW REMAINS NEARLY STATIONARY OVER THE GULF AND THE UPPER
HIGH IS OVER THE CHUKCHI SEA NEAR WRANGEL ISLAND. A WEAK EASTERLY
FLOW BETWEEN THESE TWO SYSTEMS CONTINUES TO DRAW COLD DRY AIR FROM
CANADA INTO THE CENTRAL AND NORTHERN MAINLAND. A MODERATE SURFACE LOW
OVER THE SOUTHERN GULF AND ITS ASSOCIATED WEATHER FRONT OVER THE
CENTRAL GULF HAVE MOVED CLOUDS AND AREAS OF SNOW INTO THE CENTRAL
GULF COAST OVERNIGHT. A DEVELOPING LOW SOUTH OF THE CENTRAL ALEUTIANS
CONTINUES TO MOVE NORTH.

.SHORT TERM FORECAST...
THE UPPER HIGH OVER THE WESTERN CHUKCHI SEA WILL DRIFT TO NEAR CAPE
LISBURNE BY MONDAY NIGHT. THE UPPER LOW OVER THE GULF WILL REMAIN
NEARLY STATIONARY AND AND DISSIPATE INTO AN EAST-WEST TROUGH SUN
EVENING. THE DRY EASTERLY FLOW WILL PERSIST OVER THE CENTRAL
INTERIOR.

.SOUTHCENTRAL ALASKA AND THE GULF...THE LOW OVER THE SOUTHERN GULF
WILL REMAIN NEARLY STATIONARY AND DISSIPATE SUNDAY NIGHT. THE WEATHER
FRONT ACROSS THE CENTRAL GULF WILL ALSO REMAIN STATIONARY AND
DISSIPATE SUNDAY. CLOUDS AND WIDELY SCATTERED SNOW REMAIN ALONG THE
CENTRAL GULF COAST THROUGH SUNDAY NIGHT THEN SLOWLY IMPROVE FROM THE
NORTH MONDAY. THE SNOW OVER KODIAK ISLAND WILL CONTINUE THROUGH
SUNDAY NIGHT BEFORE CHANGING TO SNOW SHOWERS MONDAY. GUSTY WINDS
THROUGH CHANNELED TERRAIN WILL DIMINISH AS THE THE LOW WEAKENS
THROUGH MONDAY.

.SOUTHWEST ALASKA...THE PREDOMINANT EASTERLY FLOW WILL KEEP MOST OF
THIS REGION OF THE STATE DRY THROUGH MONDAY. CLOUDS OVER THE GULF OF
ALASKA WILL MOVE INTO BRISTOL BAY TONIGHT AND STAY OVER THE AREA
THROUGH MONDAY. SNOW AND GUSTY WINDS ASSOCIATED WITH THE ALEUTIANS
FRONT WILL MOVE INTO THE ALASKA PENINSULA MONDAY.

...BERING SEA AND THE ALEUTIANS...A STRENGTHENING LOW SOUTH OF THE
ALEUTIANS WILL MOVE TO ABOUT 100 MILES SOUTH OF ADAK SUNDAY AFTERNOON
THEN TURN EAST AND WEAKEN 400 MILES SOUTH OF DUTCH HARBOR MONDAY. THE
ASSOCIATED WEATHER FRONT WILL MOVE RAIN, SNOW AND GALE FORCE WINDS
INTO THE CENTRAL ALEUTIANS TONIGHT AND SPREADING INTO THE EASTERN
ALEUTIANS SUNDAY.

.LONG TERM FORECAST...
THE UPPER HIGH NEAR NORTHWEST ALASKA WILL DRIFT INTO THE NORTHERN
INTERIOR THURSDAY. THIS WILL KEEP MOSTLY CLEAR SKIES OVER THE
INTERIOR SECTIONS WHICH WILL SPREAD TO THE COASTAL SECTIONS BY
MIDWEEK.
