NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
206 PM ADT FRI OCT 28 2005

.DISCUSSION...
ALOFT...A BROAD TROUGH AT 500 MB WILL REMAIN ANCHORED OVER THE
CENTRAL INTERIOR BUT WILL WEAKEN OVER TIME THROUGH MONDAY. THUS
SOUTHERLY FLOW IN EASTERN ALASKA WILL USHER WEAK DISTURBANCES WITH BOUTS
OF MOISTURE FOR THIS REGION THROUGH MONDAY. EFFECTS FROM THESE
DISTURBANCES MARCHING ALONG THE ALCAN WILL AT TIMES REACH THE
EASTERN NORTH SLOPE. HOWEVER...AS THE TROUGH BECOMES LESS
PRONOUNCED...PROGRESSIVE DISTURBANCES WILL FOLLOW SUIT AND PACK
LESS OF A PUNCH WITH EACH SUCCESSIVE ONE. ON THE WEST COAST...FOCUS
SHIFTS EVEN FARTHER WEST INTO SIBERIA...WHERE ANOTHER TROUGH WILL
DEEPEN THROUGH EARLY NEXT WEEK. THIS WILL INDUCE WEAK RIDGING OVER
THE WEST COAST ON MONDAY IN ADVANCE OF SOME WARMING ALOFT AND
STRONG UPWARD MOTION OVER THE BERING SEA.

SURFACE...POLAR FRONT WILL ARGUABLY SAG EVEN FARTHER SOUTH AND
WEST TONIGHT AND SATURDAY ENVELOPING THE ENTIRE SEWARD PENINSULA...PASSING
SAINT LAWRENCE ISLAND...AND PUSHING SOUTHWEST OF DALL POINT. AS
COLD AIR LEAKS SOUTH ALONG THE WEST COAST...EASTERN ALASKA WILL SEE A
SURFACE LOW PUSH NORTH INTO THE YUKON BRINGING SOME WARMING AND
MOISTURE INTO THE SOUTHEASTERN INTERIOR ON SATURDAY AND SATURDAY
NIGHT. THE BIG STORY FOR THE WEST WILL BE AN APPROACHING FRONT
FROM A 980 MB LOW IN THE WESTERN BERING SEA REACHING SAINT
LAWRENCE ISLAND BY MONDAY MORNING AND THE BERING STRAIT AND
SCAMMON BAY BY MONDAY AFTERNOON. HIGH PRESSURE WILL DOMINATE THE
ARCTIC AT LEAST THROUGH MONDAY.

THE INTERIOR...OVERRUNNING MOISTURE FROM THE SOUTHEAST COMBINED
WITH WEAK DYNAMICS WILL INDUCE ISOLATED SNOW SHOWERS AND
FLURRIES OVER MUCH OF THE INTERIOR THIS WEEKEND. ONLY LIGHT DUSTINGS
WILL OCCUR AT MOST...AND THEREFORE WILL BE OMITTED FROM SOME
ZONES. A SYSTEM MOVING NORTH INTO THE YUKON SATURDAY MAY INCREASE
CHANCES OF ACCUMULATING SNOW IN THE SOUTHEASTERN INTERIOR AND
WINDWARD SLOPES OF THE EASTERN BROOKS RANGE THROUGH SATURDAY NIGHT.
CLEARING SKIES OVER PORTIONS OF THE TANANA VALLEY AND THE YUKON
FLATS WILL CERTAINLY ALLOW TEMPERATURES TO DROP TO SUBZERO DURING
OVERNIGHT AND MORNING HOURS.

THE ARCTIC COAST AND NORTH SLOPE...A DISTURBANCE MOVING OVER THE
ARCTIC COAST WILL PUSH ACCUMULATING SNOW EASTWARD FROM BARROW
TONIGHT AND SATURDAY. HIGH PRESSURE HUGGING THE SURFACE WILL STILL
KEEP WINDS EASTERLY. SATURDAY AND SUNDAY...SNOW WILL LIKELY FALL
OVER THE EASTERN ARCTIC COAST DUE TO NORTHWARD MOVING DISTURBANCES
OVER THE YUKON.

THE WEST COAST...LOW CLOUDS STILL HANG PERSISTENT OVER THE
CHUKCHI AND BERING SEAS WITH ONLY A FEW AREAS FREE OF
CLOUDS...MOSTLY IN AREAS OF SIGNIFICANT OFFSHORE FLOW LIKE FAR
EASTERN SHORES OF NORTON SOUND AND KOTZEBUE SOUND. NORTHEASTERLY
FLOW PREVIOUSLY ASSIGNED TO NOME AND OTHER SOUTHERN SEWARD
PENINSULA COASTAL TOWNS IS NOT DOING A GREAT JOB AT KEEPING CLOUDS
AT BAY...INDEED EDDIES IN THE STRATUS CONTINUE TO BACK UP MVFR CLOUD
DECKS ONTO THE COAST. STRONG WINDS WILL EVENTUALLY RELENT AROUND
POINT HOPE LATE TONIGHT. AS LOW MOVES INTO GULF OF ALASKA TONIGHT
SYNOPTIC WINDS WILL TRANSITION FROM NORTHEAST TO NORTHERLY AND
EVENTUALLY ONSHORE TRAINS OF SNOW SHOWERS MAY DEVELOP OVER SAINT
LAWRENCE ISLAND...THE VILLAGES OF THE YUKON DELTA AND CAMPS IN THE
BERING LAND BRIDGE PRESERVE FOR SUNDAY. MARINERS SHOULD BE AWARE
OF WINDS PICKING UP IN THE OUTER WATERS IN RESPONSE TO AN
APPROACHING FRONT FROM THE WEST. SNOW WILL BEGIN ON SAINT LAWRENCE
ISLAND MONDAY MORNING AND SPREAD TO WALES AND SCAMMON BAY BY THE
AFTERNOON. THE WESTERN INTERIOR WILL NO DOUBT DEAL WITH PESKY
STRATUS ESPECIALLY WHILE THE REGION LIES BETWEEN SYNOPTIC SYSTEMS EAST
AND WEST.

THE EXTENDED...SNOW LOOKS LIKELY FOR THE WEST COAST THROUGH THE
EARLY PART OF NEXT WEEK AS SURFACE FLOW DEVELOPS ON TAIL END OF FRONT.
THE SOUTHEASTERN INTERIOR WILL ALSO DODGE SNOW CHANCES AS ZONE OF
SYSTEMS SKIRT FROM THE BERING SEA THROUGH THE GULF AND ACROSS THE
YUKON. COLD AIR WILL REMAIN ENTRENCHED NORTH OF A LINE FROM SAINT
LAWRENCE ISLAND THROUGH THE ALASKA RANGE THROUGH MID WEEK.
