NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
639 AM AKST FRI DEC 5 2014

.DISCUSSION...
THE RIDGE OF HIGH PRESSURE OVER THE BEAUFORT AND NORTHERN CHUKCHI
SEAS WILL PERSIST FOR THE NEXT COUPLE OF DAYS...THEN BEGIN TO
WEAKEN ON MONDAY. THE 974 MB LOW SOUTHWEST OF DUTCH HARBOR WILL
MOVE AND MERGE WITH A DEVELOPING LOW OVER THE SOUTHWEST GULF OF
ALASKA. A WAVE ON THE TRAILING FRONT ASSOCIATED WITH THIS SYSTEM
WILL DEVELOP INTO A NEW LOW PRESSURE CENTER ON SATURDAY. THIS
NEW CENTER WILL MOVE NORTH OVER THE SOUTHEAST GULF OF ALASKA...THEN
TURN NORTHWEST TO BE 970 MB NEAR KODIAK ISLAND SUN MORNING...MOVE
INTO BRISTOL BAY LATER SUNDAY...THEN TURN SOUTHWEST AND BEGIN TO
WEAKEN. THE FRONTAL SYSTEM ASSOCIATED WITH THIS LOW IS EXPECTED TO
BE STRONGER THAN THE RATHER WEAK ONES THAT HAVE COME UP FROM THE
GULF RECENTLY. IT WILL LEAVE MOST OF ITS MOISTURE BEHIND ON THE
CHUGACH AND ALASKA RANGES AS IT MOVES INLAND...BUT WILL MAKE A
SIGNIFICANT CONTRIBUTION TO THE INCREASING PRESSURE GRADIENT OVER
NORTHERN ALASKA.

THE 962 MB LOW 700 NM SOUTHWEST OF SHEMYA WILL MOVE RAPIDLY EAST
TO BE 200 NM SOUTHWEST OF ADAK AT 3AM SAT...ALSO MAKING A
CONTRIBUTION TO THE INCREASING PRESSURE GRADIENT. THIS INCREASE
IS IN PROCESS NOW AND WILL CONTINUE THROUGH SUNDAY AT LEAST. THE
WINDS EXPECTED TO DEVELOP WILL AFFECT MOST PORTIONS OF NORTHERN
ALASKA FROM THE BROOKS RANGE SOUTH...AND IT WILL CERTAINLY BE
WINDY IN THOSE AREAS INCLINED TO BLOW FROM THE EAST.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
