AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 PM ADT SUN AUG 21 2005

.DISCUSSION...
NO MAJOR CHANGES FROM LAST PACKAGE. GFS MODEL STILL LOOKS THE MOST
REASONABLE AND WILL USED IN AFTERNOON FORECAST PACKAGES.  DEVELOPING
LOW PRESSURE CENTER NEAR SHEMYA THIS AFTERNOON IS STILL ON TRACK TO
BE NEAR THE PRIBILOF ISLANDS MON AFTERNOON AND NEAR PAEH TUE
AFTERNOON. CENTRAL PRESSURE SHOULD DROP DOWN INTO THE LOWER 990S NEAR
THE PRIBILOFS AND IN THE LOW 980S AT IT APPROACHES THE BRISTOL BAY
COAST. EXPECT GALES TO STORM FORCE WINDS ON BACKSIDE OF CENTER AS IT
TRACKS NE. GALES GENERALLY ON THE SOUTH AND SE QUADS. STRONG GAP
WINDS LIKELY OVER PORTIONS OF SOUTHCENTRAL(ESPECIALLY TURNAGAIN ARM,
PORTAGE GAP...AND HIGHER ELEVATIONS).

STRONG FRONTAL THROUGH MOVING ACROSS SOUTHCENTRAL/NORTH GULF
CONTINUES EAST AND SHOULD WEAKEN. STRONG SUBSIDENCE ON BACKSIDE WITH
SOME CLOUD BREAKS SHOULD LEAD TO PATCH NIGHT AND MORNING FOG/STRATUS
OVER SOUTHCENTRAL AND PORTIONS OF SW ALASKA TONIGHT.

.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...NONE.
MARINE...SEE CURRENT PACKAGES
FIRE WEATHER...NONE.
