AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 AM AST SUN MAR 4 2007

.DISCUSSION...THE OVERALL PATTERN HAS CHANGED VERY LITTLE AS AN
UPPER RIDGE REMAINS IN PLACE OVER THE BERING SEA WITH A TROUGH
ACROSS EASTERN ALASKA. A WEAK SHORTWAVE TRAVELING THROUGH SOUTHWEST
ALASKA THIS MORNING WILL PROVIDE CLOUDS AND A FEW LIGHT SNOW SHOWERS
ACROSS THE KUSKOKWIM DELTA WITH LITTLE OR NO IMPACT ELSEWHERE. WINDS
WILL INCREASE AFTER THE SHORTWAVE PASSAGE AS COLD ADVECTION KICKS IN.
AN UPPER JET COMING DOWN FROM THE NORTH WILL HELP AID IN MOMENTUM
TRANSFER TRANSLATING TO VERY WINDY CONDITIONS THROUGH N-S GAPS IN SW
ALASKA. THE WINDY CONDITIONS WILL STRETCH AS FAR EAST AS THE
MATANUSKA VALLEY WHERE A HIGH WIND WATCH WILL BE ISSUED FOR MONDAY AS
THE JET STREAK TRAVELS OVERHEAD. FURTHER EAST THE WINDS WILL INCREASE
DUE TO A TIGHTENING PRESSURE GRADIENT AND COLD ADVECTION...BUT THE
LACK OF STRONG UPPER LEVELS WINDS SHOULD PRECLUDE WINDS FROM REACHING
HIGH WIND CRITERIA.

LOW PRESSURE FROM THE CENTRAL PACIFIC GETS DRAWN NORTHEAST TOWARD
THE GULF OF ALASKA BY MID-WEEK AS THE BLOCKING RIDGE OVER THE BERING
PROMOTES MORE OF A NORTHWARD STORM TRACK. THE TRACK AND INTENSITY OF
THE LOW IS STILL IN QUESTION...BUT REGARDLESS...SNOW RETURNS TO
COASTAL AREAS OF SOUTH CENTRAL ALASKA FOR THE FIRST TIME IN WEEKS.

.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...HIGH WIND WATCH 111.
         FLOOD WARNING 141.
MARINE...GALE 130 132 140 150 155 165 175 176.
         HEAVY FREEZING SPRAY 120 121 125 129 130 132 138 140 141.
