AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 AM ADT SUN MAY 14 2006

.DISCUSSION...
AN UPPER LEVEL RIDGE ORIENTED NORTHEAST TO SOUTHWEST REMAINS OVER
ALASKA BLOCKING ANY WEATHER SYSTEM FROM THE WEST FROM COMING FAR
INLAND. ONE SUCH SYSTEM IS A FRONT THAT CAME ONSHORE OVERNIGHT
BRINGING A MIX OF SNOW AND RAIN ALONG THE WESTERN COAST OF ALASKA AND
DOWN ALONG THE AKPEN. DO NOT EXPECT THIS FRONTAL PRECIPITATION ALONG
WITH CLOUD COVER TO MAKE IT MUCH FURTHER EAST PAST THE VICINITY OF
155W. AS SATELLITE AND RADAR SHOW...ANYTHING EAST OF THIS IS QUITE
CLEAR EXCEPT FOR A SHORTWAVE MOVING IN WEST FROM THE YUKON STARTING
TO COVER THE LOWER PART OF COPPER RIVER BASIN AND DELTA THIS MORNING.

SOUTHCENTRAL...THE SHORTWAVE COMING FROM THE EAST WILL BRING
SCATTERED SHOWERS MOSTLY TONIGHT AND MONDAY AROUND THE AREA...MOSTLY
AFFECTING THE COPPER RIVER VALLEY AND PRINCE WILLIAM SOUND. THEN LOOK
FOR PARTLY TO MOSTLY CLOUDY SKIES WITH OCCASIONAL SHOWERS AS A WEAK
LOW HANGS AROUND BY THE EASTERN PART OF OUR AREA BEFORE A HIGH IN THE
GULF PUSHES IT NORTH ON THURSDAY.

SOUTHWESTERN ALASKA...THE NEWLY ARRIVED FRONT WILL DISSIPATE OVER
LAND TODAY AS ITS ENERGY IS PUSHED SOUTH FROM THE HIGH PRESSURE RIDGE
BELOW THE ALEUTIANS. DRIER WEATHER WILL PREVAIL UNTIL TUESDAY WHEN A
BERING LOW WILL WRAP SOME OF ITS MOISTURE AROUND AND ALONG THE COAST.
AS THIS LOW DISSIPATES ANOTHER LOW FROM THE NORTH PACIFIC WILL HEAD
NORTH AND BRING SOME MORE MOISTURE THURSDAY AND FRIDAY.

AKPEN AND BERING...A LOW JUST SOUTH OF KAMCHATKA WILL BRING STORM
FORCE WINDS AND RAIN OVER THE WESTERN ALEUTIANS TONIGHT AND MONDAY.
THIS HELPED PROMPT A STRONG WIND HEADLINE TO BE ADDED TO THESE AREAS.
AS THE LOW MOVES FURTHER NORTH AND OVER COLDER WATERS IT WILL FADE
AND DISSIPATE NEAR EASTERN SIBERIA THURSDAY. A NORTH PACIFIC LOW WILL
HEAD NORTH BRINGING MORE MOISTURE AND GALE FORCE WIND TO THE EASTERN
ALEUTIANS AND AKPEN FRIDAY.
