AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
1200 PM ADT SAT MAY 28 2005

.DISCUSSION...MODEL INITIALIZATIONS AND FORECAST TRENDS REASONABLE.

.EAST...WEAK LOW SOUTH OF THE KENAI PEN THIS MORNING WILL MOVE TO
OVER THE BARREN ISLANDS TONIGHT THEN DISSIPATE. THE PRESSURE GRADIENT
ASSOCIATED WITH FRONTAL TROUGH AND NARROW RIDGE OVER THE NORTH GULF
WILL CONTINUE TO PRODUCE BRISK WINDS OVER CHANNELED AREAS OF
SOUTHCENTRAL ALASKA THROUGH THIS EVENING. RAIN OVER MUCH OF THE NORTH
GULF WILL DIMINISH THROUGH TONIGHT. THERMAL LOW OVER THE INTERIOR IN
COMBINATION WITH NARROW RIDGE OVER THE GULF WILL PRODUCE GUSTY SOUTH
WINDS OVER THE COPPER RIVER BASIN THROUGH THIS EVENING. GENERAL
PATTERN IS FOR ANCHOR LOW SOUTH OF THE AK PEN TO DRIFT INTO THE
EAST-CENTRAL BERING SEA OVER THE NEXT COUPLE OF DAYS AND WEAKEN.
EXPECT WEAK RIDGE NOSE TO CONTINUE OVER THE NORTH GULF.
HOWEVER...SHALLOW WAVES MOVING OUT OF THE SOUTHERN GULF WILL HOLD THE
THREAT OF CLOUDS WITH SOME SCATTERED PRECIPITATION THROUGH MONDAY.

.WEST...MAIN 989 LOW SOUTH OF THE AK PEN IS STACKED WITH THE UPPER
CENTER AND SHOULD BE SLOWLY FILLING. EXPECT CENTER TO DRIFT NORTH OF
DUTCH HARBOR MONDAY AND BECOME MORE DIFFUSE. DO NOT SEE ANY REAL
WINDS OVER THE AREA TO WORRY ABOUT. MAY SEE A SLIGHT CHANCE OF
THUNDERSTORMS OVER THE NORTHERN KUSKOKWIM VALLEY THIS EVENING...BUT
CONDITIONS SHOULD BECOME MORE STABLE SUNDAY AND MONDAY WITH COOLING
850MB TEMPS.
