NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
139 PM AKST TUE JAN 27 2009

.DISCUSSION...

A COLD UPPER LOW IS DIGGING INTO NORTHERN AK TODAY AND WILL
REMAIN OVER MUCH OF THE STATE WELL INTO NEXT WEEK. THE AIRMASS IS
EVERY BIT AS COLD AS THE ONE THAT PRODUCED THE COLD OUTBREAK
EARLIER IN THE MONTH.

NORTH SLOPE...N-NW FLOW ALOFT ON THE BACK SIDE OF THE LOW THAT IS
DIGGING TO THE SOUTH WITH SOUTHWEST FLOW AHEAD OF THE LOW ACROSS
THE EASTERN BEAUFORT SEA. TEMPERATURES ARE COLD ENOUGH FOR WIND
CHILLS IN THE 50 TO 60 BELOW RANGE...AND IT LOOKS LIKE THE WIND
CHILLS WILL REMAIN IN ADVISORY RANGE THROUGH AT LEAST TODAY. AS
THE UPPER LOW SLIDES EAST LATER THIS AFTERNOON,THERE WILL LIKELY
BE SOME LOW WIND CHILLS ALONG THE BEAUFORT SEA COAST INTO
WEDNESDAY.

INTERIOR...AS THE UPPER LOW DIGS IN IT WILL PUSH THE ARCTIC FRONT
SOUTH INTO THE CENTRAL INTERIOR THIS AFTERNOON.  THE PUSH OF COLDER
AIR WILL LIKELY BE ACCOMPANIED BY AREAS OF LIGHT SNOW. THE WIND
WILL ALSO PICK UP ACROSS THE SUMMITS WHICH WILL LEAD TO SOME AREAS
OF BLOWING SNOW. IT LOOKS LIKE THE SUMMITS WILL REMAIN IN THE
CLOUDS...AND THUS TEMPERATURES WILL PROBABLY NOT BE COLD ENOUGH
INITIALLY FOR LOW WIND CHILLS...BUT THIS WILL NEED TO BE WATCHED.
FOR NOW WILL MAKE SOME CHANGES TO BEEF UP THE WINDS AND MAKE
MENTION OF SOME BLOWING SNOW ON THE SUMMITS. A LOW MOVING INTO THE
NORTHERN GULF WILL LIKELY SPREAD CLOUDS AND SOME SNOW INTO PARTS
OF THE SOUTHERN INTERIOR WEDNESDAY NIGHT AND THURSDAY. IT MAY
CLEAR OUT ENOUGH IN PARTS OF THE WESTERN AND NORTHERN INTERIOR
WEDNESDAY NIGHT TO ALLOW TEMPERATURES TO DROP TO 40 BELOW OR
LOWER.

WEST COAST...FAIRLY QUIET WEATHER EXPECTED FOR THE NEXT FEW DAYS
WITH TEMPERATURES TRENDING COLDER FROM THE SEWARD PENINSULA SOUTH
INTO SW AK. THERE IS ENOUGH WIND ALONG THE NW COAST FOR SOME LOW
WIND CHILLS AND ISSUED A WIND CHILL ADVISORY FOR THE CHUKCHI SEA
COAST AS WELL AS THE NOATAK VALLEY. WILL NEED TO KEEP A CLOSE EYE
ON TEMPS AND WIND FROM THE SEWARD PENINSULA NORTH FOR THE
POSSIBILITY OF ADDITIONAL ADVISORIES. THE SOUTHWEST ZONES LOOK TO
REMAIN TOO WARM FOR ANY WIND CHILL CONCERNS THROUGH AT LEAST THIS
EVENING.

MID-RANGE...NORTHERN AK TO REMAIN LOCKED IN A DEEP AND COLD UPPER
TROUGH INTO NEXT WEEK. THIS WILL KEEP TEMPERATURES WELL BELOW
AVERAGE WITH LITTLE SIGNIFICANT SNOWFALL. HARD TO SAY WHERE IT
WILL BE CLOUDY AND WHERE THE SKY WILL CLEAR...BUT THE STORM TRACK
WILL LIKELY KEEP THE BEST CHANCE OF CLOUDS AND SNOW ACROSS THE
SOUTHEAST HALF OF THE INTERIOR. WHERE THE SKY DOES CLEAR TEMPS
COULD CERTAINLY RIVAL THOSE OF EARLIER THIS MONTH.
