Gale Warning 599, NWS Anchorage, AK

AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
400 PM ADT WED AUG 30 2006

.DISCUSSION...ON THE HEMISPHERIC LEVEL THERE ARE THREE DOMINANT WAVES
WITH THE STRONGEST ONE BEING THE TROUGH OVER ALASKA. BY THIS WEEKEND
THIS SHOULD CHANGE TO A FOUR WAVE PATTERN WITH THE WAVE OVER ALASKA
WEAKENING AND BECOMING A CUT OFF LOW IN THE GULF OF ALASKA. AN UPPER
LEVEL RIDGE OVER THE BERING SEA WILL ALSO PUSH INTO THE WESTERN PARTS
OF THE MAINLAND OF THE STATE THIS WEEKEND AND CLEAR THINGS OUT A BIT
FOR INTERIOR AREAS.

MOVING TO A CLOSER LOOK AT THE STATE...THERE IS AN UPPER LEVEL LOW
CENTERED OVER BRISTOL BAY THAT WILL MOVE TO NEAR KODIAK ISLAND
OVERNIGHT AND THEN DRIFT INTO PRINCE WILLIAM SOUND THURSDAY NIGHT.

THE SURFACE LOW WILL BE NEAR KODIAK ISLAND THIS AFTERNOON AND EVENING
BEFORE SLOWLY MOVING INTO THE GULF OF ALASKA FRIDAY.
A WEATHER FRONT ASSOCIATED WITH THIS LOW IS IN THE WESTERN GULF OF
ALASKA THIS AFTERNOON AND WILL MOVE TO ALONG THE NORTH GULF COAST
TONIGHT. EXPECT GALE FORCE WINDS ALONG THE NORTH GULF COAST AS THIS
FRONT MOVE THROUGH THE AREA.
LOOK FOR GUSTY NORTHWEST WINDS ALONG THE ALASKA RANGE AND EASTERN
ALEUTIAN ISLANDS AS THE PRESSURE GRADIENT GET TIGHT BETWEEN THIS LOW
IN THE GULF AND THE RIDGE IN THE BERING SEA.

GFS AND NAM ARE IN PRETTY GOOD AGREEMENT TODAY ON THE MAIN FEATURES.
THE GFS IS FAVORED OVERALL DUE TO THE WAY IT IS HANDLING THE LOW NEAR
KODIAK ISLAND.
