NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
221 PM AKST TUE JAN 19 2016

.SYNOPSIS...
ALOFT...
THE LONG WAVE PATTERN CONSISTS OF A TROUGH OVER MAINLAND ALASKA
THE NORTHERN PACIFIC WITH A RIDGE OVER WESTERN CANADA. THIS
PATTERN PERSISTS THROUGH FRI THEN RETROGRADES OVER THE WEEKEND. THE
RIDGE THEN BUILDS NW OVER MAINLAND ALASKA FROM THE WEEKEND INTO
NEXT WEEK. THERE ARE SEVERAL WEAK SHORT WAVE TROUGHS/SURFACE
WEATHER FRONTS THAT WILL MOVE NORTHWEST ACROSS THE INTERIOR OVER
THE NEXT SEVERAL DAYS IN THIS FLOW CAUSING LIGHT SNOW OVER THE
INTERIOR. TEMPERATURES WILL REMAIN NEAR TO JUST ABOVE NORMAL FOR
MOST OF NORTHERN ALASKA THROUGH FRI WITH A WARM UP TO WELL ABOVE
NORMAL SOUTH OF THE BROOKS RANGE THIS WEEKEND INTO NEXT WEEK.

A SHORT WAVE TROUGH FROM ARCTIC VILLAGE TO THE BERING STRAIT WILL
PERSIST THROUGH THU. THIS WILL SERVE AS A NORTHERN LIMIT TO CLOUDS
AND ANY POTENTIAL PRECIPITATION.

850 MB TEMPERATURES RANGE FROM -4C IN THE YUKON DELTA TO -19C
OVER THE NORTH SLOPE. LITTLE CHANGE THROUGH THU.

SURFACE...
A STRONG RIDGE OF HIGH PRESSURE STRETCHING FROM THE CHUKCHI SEA
EAST ACROSS THE NORTH SLOPE OF ALASKA WILL WEAKEN AND MOVE NORTH
OF THE COAST THU. THIS IS CAUSING AREAS OF FLURRIES AND FOG OVER
THE NORTH SLOPE. LIGHT N-NW WINDS FROM BARROW EAST...AND EAST
WINDS WEST OF BARROW.

AN OCCLUDED FRONT ALOFT STRETCHING FROM MCGRATH TO DAWSON WILL
MOVE TO ANVIK TO TANANA TO EAGLE BY 3AM WED...TO THE YUKON DELTA
TO OLD CROW BY 3PM WED...TO NORTON SOUND TO OLD CROW BY 3AM
THU...AND THEN DISSIPATE ALONG A NOME TO OLD CROW LINE BY 3PM
THU. SNOW ALONG AND SOUTH OF THIS THIS FRONT WILL DIMINISH TO
SCATTERED SNOW SHOWERS BY WED AND TO ISOLATED SNOW SHOWERS BY WED
NIGHT. STRONG NE WINDS AND BLOWING SNOW ARE OCCURING NORTH OF THE
FRONT...ESPECIALLY ALONG THE SOUTH SLOPES OF THE BROOKS
RANGE...THE INTERIOR UPLANDS AND FROM POINT HOPE TO GAMBELL. WINDS
WILL DECREASE SOUTH OF THE FRONT.

A SECOND AND WEAKER WEATHER FRONT OVER SE ALASKA WILL MOVE TO
GLENNALLEN TO DESTRUCTION BAY BY 3AM WED...TO DENALI TO CHICKEN BY
3PM WED...TO MCGRATH TO EAGLE BY 3AM THU...AND TO ANIAK TO EAGLE
BY 3PM THU. THIS WILL CAUSE ISOLATED SNOW SHOWERS TO CONTINUE OVER
THE SOUTHERN INTERIOR THROUGH THU.

A THIRD WEATHER FRONT WILL MOVE NORTH TO EXTREME SE INTERIOR BY
3PM THU...AND THEN TO DENALI TO OLD CROW BY FRI. THIS WILL BRING
SNOW TO THE SE INTERIOR THU AND SPREAD A CHANCE OF SNOW TO THE
REMAINDER OF THE INTERIOR FRI.

&&

.DISCUSSION...
MODELS INITIALIZE WELL AND SHOW SIMILAR SOLUTIONS THROUGH THU ON
MOST FIELDS. SLIGHT DIFFERENCES IN PRECIPITATION FIELDS. FAVOR
THE GFS SOLUTION WHICH IS MORES CONSISTENT WITH WHAT WAS SEEN
YESTERDAY. START TO SEE DIVERGENCES IN SHORT WAVE SPEED AND
STRENGTH STARTING THIS WEEKEND...BUT LONG WAVE PATTERNS REMAIN
SIMILAR INTO NEXT WEEK.
