SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
525 PM AKDT MON APR 9 2012

.ANALYSIS AND UPPER LEVELS...AN UPPER LEVEL LONGWAVE TROUGH EXTENDS
OUT OF RUSSIA AND OVER THE WESTERN ALEUTIAN ISLANDS WHILE AN UPPER
RIDGE IS PUSHING UP FROM ALONG THE ROCKY MOUNTAINS INTO THE INTERIOR
OF THE STATE. THIS RIDGE WILL BUILD OVER THE INTERIOR OF THE STATE
THROUGH MID WEEK. A STRONG SURFACE LOW IS SOUTH OF THE ALEUTIAN
ISLANDS AND MOVING EASTWARD IN CONJUNCTION WITH THE JET STREAM.
A SURFACE HIGH IS ALSO OVER THE GULF OF ALASKA THAT PUSHES INTO THE
EASTERN HALF AND THE INTERIOR OF THE STATE.

.MODEL DISCUSSION...MODELS ARE DOING VERY GOOD AND ARE ALL HANDLING
THE FEATURES CONSISTENTLY. RUN TO RUN CONSISTENCY IN THE MODELS IS
ALSO VERY GOOD.

.SHORT TERM FORECAST...MOSTLY CLEAR SKIES WILL PERSIST FROM ANCHORAGE
EASTWARD. MID LEVEL CLOUDS ARE IN COOK INLET AND ARE TRYING TO MOVE
NORTHEASTWARD BUT ARE RUNNING INTO THE RIDGE. FLOW IS EXPECTED TO
BECOME MORE NORTHEASTERLY OVERNIGHT WHICH SHOULD BEGIN TO CLEAR OUT
SOME OF THE CLOUDS OVER THE KENAI PENINSULA TOMORROW.
THE WEAKENING FRONT OVER KODIAK ISLAND THAT REACHES INTO BRISTOL BAY
AND THE KUSKOKWIM VALLEY WILL KEEP ONSHORE FLOW AND SOME SHOWERS IN
THE KODIAK ISLAND AREA THROUGH TOMORROW WHILE THE PRECIPITATION WEST
OF THE ALEUTIAN RANGE SHOULD END TONIGHT.
THE LARGE LOW SOUTH OF THE ALEUTIAN ISLANDS IS ON AN EASTERLY TRACK
WHICH WILL KEEP THE HEAVIEST PRECIPITATION FROM DUTCH HARBOR TO COLD
BAY. THIS IS DUE TO THE GREATEST LIFT REMAINING SOUTH OF THE FORECAST
AREA EXCEPT FOR THAT REGION. WINDS ARE INCREASING IN THE DUTCH HARBOR
AREA AND PRECIPITATION TYPE SHOULD REMAIN SNOW WHICH WILL BRING IN
THE POSSIBILITY OF BLOWING SNOW. AS OF THIS AFTERNOON IT DOES NOT
LOOK LIKE BLIZZARD CONDITIONS WILL OCCUR...THOUGH THERE IS A SLIGHT
RISK THIS EVENING.

.LONG TERM FORECAST...
A RELATIVELY PERSISTENT AND BENIGN WEATHER PATTERN TO PERSIST THROUGH
LATE WEEK. A VIGOROUS SHORTWAVE DROPS SOUTH THROUGH THE BERING ON FRI
AND MODELS DEPICT IT HELPING TO DEVELOP A LARGE LOW OVER THE CENTRAL
PACIFIC THAT MOVES TOWARDS THE SOUTHERN GULF BY MID WEEKEND. FORECAST
CHALLENGES WILL LIKELY SURROUND THIS FEATURE IN THE LONG TERM PERIOD.
AS IT GETS CLOSER TO THE MAINLAND...WILL LIKELY SEE INCREASING
CHANCES OF PRECIPITATION.

.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...NONE.
MARINE...GALE 150 155 170 171 172
FIRE WEATHER...NONE.
