SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE ANCHORAGE AK
500 AM AKDT MON JUN 13 2011

CORRECTED TYPO

.MODEL DISCUSSION...
MODELS REMAIN IN GOOD GENERAL AGREEMENT THROUGH THE SHORT TERM. AGAIN
THE ONLY DISCREPANCY BEING HOW THE UPPER LOW OVER BRISTOL BAY TRACKS.
THE MODEL SPREAD WITH THIS FEATURE HAS BECOME LESS OVER THE PREVIOUS
DAYS AND SEEMS TO BE CLOSELY RELATED TO THE STRENGTH OF THE TROUGH
OVER NORTHWEST ALASKA ASSOCIATED WITH THE NORTHERN BEAUFORT SEA UPPER
LOW. THE SOLUTIONS DIVERGE AS THE LOW DRIFTS OVER THE NORTHERN GULF
COAST/SOUTHERN MAINLAND.

.ANALYSIS AND UPPER LEVELS...
UPPER LEVEL LOW CONTINUES TO DRIFT OVER THE PRIBILOFS BRINGING A
STRAY SHOWER TO SAINT PAUL AND SAINT GEORGE ISLANDS. TROUGH OVER THE
ALASKAN PENINSULA AND SOUTH OF KODIAK ISLAND CONTINUES TO SHEAR APART
BRINGING SCATTERED SHOWERS TO BRISTOL BAY. NORTHERN ALASKA CONTINUES
TO STAY UNDER THE INFLUENCE OF A TROUGH ANCHORED JUST WEST OF BANKS
ISLAND EXTENDING SOUTHWEST TOWARDS THE NORTH SLOPE COMBINING WITH THE
SURFACE THERMAL TROUGH TO BRING ROUNDS OF SCATTERED SHOWERS OVER THE
CENTRAL INTERIOR. A WEAK DIRTY RIDGE LIES OVER THE SOUTHERN MAINLAND
BETWEEN THE COMPLEX OF UPPER LEVEL LOWS. AT THE SURFACE THREE WEAK
SURFACE REFLECTIONS OF THE UPPER SYSTEMS EXTENDS FROM THE PRIBILOFS
SOUTHEAST ACROSS THE ALASKAN PENINSULA DOWN TO THE SOUTHEASTERN GULF.
A WEAK SURFACE RIDGE BUILDS OVER THE WESTERN ALEUTIANS. SURFACE
RIDGING OVER THE NORTHERN AND EASTERN GULF COAST REMAINS SANDWICHED
BETWEEN THE AFOREMENTIONED GULF TROUGH AND THERMAL TROUGH OVER THE
CENTRAL INTERIOR.

.SHORT TERM FORECAST...
SOUTHCENTRAL ALASKA...THE WEAK RIDGE OVER THE AREA WILL BE SLOWLY
PUSHED TO THE NORTH OVER THE NEXT FEW DAYS AHEAD AN IMPULSE SLOWLY
DRIFTING EAST OVER THE GULF. MOSTLY CLOUDY SKIES WITH THE CHANCE FOR
SHOWERS MAINLY OVER KODIAK ISLAND AND THE SOUTHWEST KENAI PENINSULA.
ISOLATED SHOWERS AND THUNDERSTORMS REMAIN POSSIBLE OVER THE COPPER
RIVER BASIN.

SOUTHWEST ALASKA...SCATTERED SHOWERS OVER THE KUSKOKWIM DELTA AND
MORE NUMEROUS SHOWERS OVER BRISTOL BAY TODAY AND TONIGHT. ISOLATED
SHOWERS WITH THE CHANCE FOR A THUNDERSTORM OVER THE KUSKOKWIM VALLEY
IN THE EVENING.

BERING SEA AND ALEUTIANS...LOOK FOR A PERIOD OF QUIET WEATHER OVER
THE WESTERN AND CENTRAL ALEUTIANS BETWEEN SIGNIFICANT SYSTEMS. THE
NEXT TROUGH CURRENTLY SOUTHEAST OF KAMCHATKA PENINSULA WILL BEGIN TO
SEND MULTIPLE IMPULSES TOWARD THE ALEUTIAN CHAIN BEGINNING TUESDAY
AND CONTINUING THROUGHOUT THE WEEK.

.LONG TERM FORECAST...
CURRENT SHORTWAVE OVER THE WESTERN GULF WILL DRIFT EASTWARD TOWARD
THE SOUTHEAST MAINLAND BRINGING AN INCREASED CHANCE OF SHOWERS
ESPECIALLY ALONG COASTAL AREAS. THE UPPER LOW OVER THE PRIBILOFS WILL
CONTINUE EASTWARD TOWARD THE MAINLAND AND BRING SHOWERS TOWARD
MIDWEEK. THE WEAK PATTERN BREAKS DOWN TOWARD THE END OF THE WEEK AS A
NORTH PACIFIC LOW SENDS MULTIPLE SHORTWAVES AND ASSOCIATED
FRONTS/INCREASES IN SIGNIFICANT WEATHER.
