AREA FORECAST DISCUSSION
SOUTH CENTRAL AND SOUTHWEST ALASKA
500 PM ADT TUE JUL 12 2005

.DISCUSSION...

...HEMISPHERIC...
5 WAVE PATTERN WITH THE ANCHOR LOW JUST TO THE EAST OF GREENLAND.
ENTIRE AOR REMAINS UNDER A BROAD ELONGATED TROUGH.

...AT THE SURFACE...
MINOR 1003 MB LOW CURRENTLY NEAR COLD BAY IS PUSHING UP AGAINST A
RIDGE OVER THE GULF OF ALASKA RESULTING IN SMALL CRAFT TO NEAR GALE
FORCE WINDS OVER THE WESTERN GULF, WATERS EAST OF KODIAK, AND THE
BARRENS. MOISTURE ASSOCIATE WITH THE LOW IS SPREADING INTO
SOUTHWESTERN ALASKA PRODUCING RAIN OVER MUCH OF THE SOUTHWESTERN PART
OF THE STATE. WEST OF THE STATE, ANOTHER LOW IS HEADING TOWARD THE
ALEUTIANS.

...FOR THE FORECAST...
AS THE SURFACE AND UPPER LOW LEVEL LOW MOVE INTO THE GULF THE RIDGE
OF HIGH PRESSURE WILL BUILD IN THE EASTERN GULF, MOVE TO THE
PANHANDLE AND EXTEND INTO THE EASTERN INTERIOR BY LATE TONIGHT AND
WED. THE CUT OFF OF THE SOUTHWEST MOIST COOL FLOW INTO THE SOUTHWEST
MAINLAND WILL RESULT IN DIMINISHED CLOUDS AND RAIN FORE THAT REGION.
EAST OF THE ALASKA RANGE THE UPPER LOW MOVES INTO THE GULF AND HOLDS
AND MOIST COOL EASTERLY FLOW OVER THE REGION. EXPECT THE TYPICAL
RAINY COOL CONDITIONS ALONG THE UPSLOPE REGIONS ALONG THE GULF WITH
THE DRIER CROSS MOUNTAIN FLOW ON THE LEEWARD SIDES OF THE COASTAL
MOUNTAINS AND THE LEEWARD SIDE OF THE TALKEETNA MOUNTAINS.

IN THE BERING SEA THE LOW NOW NEAR SHEMYA WILL CONTINUE TO MOVE ALONG
THE CHAIN AND WEAKEN. AS THIS LOW MOVES EAST WEAK HIGH PRESSURE WILL
MOVE INTO THE WESTERN BERING SEA. THE MAIN ISSUE OF CONCERN IS FOR
DENSE FOG IN THE BERING SEA UNDER THIS WEAK RIDGE OF HIGH PRESSURE AS
IT MOVES INTO THE WESTERN AND CENTRAL BERING SEA OFFSHORE AREAS AND
THE WESTERN AND CENTRAL ALEUTIANS THROUGH THURSDAY.
