NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
143 PM AST SAT JAN 27 2007

.DISCUSSION...

ALOFT...
MODEL RUNS ARE SIMILAR ON HANDLING OF THE LARGE
SCALE FEATURES THROUGH WEDNESDAY...ALTHOUGH THERE ARE
SOME DIFFERENCES IN THE SMALLER DETAILS. SOUTHERLY FLOW
WILL PERSIST THROUGH MONDAY WITH SEVERAL SMALL SCALE LOW
AMPLITUDE RIDGES AND TROUGHS RAPIDLY MOVING THROUGH.

A HIGH AMPLITUDE RIDGE WILL BUILD TUESDAY NIGHT AND
WEDNESDAY...WITH THE RIDGE AXIS EXTENDING FROM
THE EASTERN GULF OF ALASKA NORTHWESTWARD TO WRANGEL
ISLAND BY WEDNESDAY AFTERNOON. 500 MB HEIGHTS WILL
BE MUCH ABOVE NORMAL BY WEDNESDAY AFTERNOON...WITH
HEIGHT ANOMALIES UP TO 35-45 DAM OVER A SUBSTANTIAL
PART OF THE FORECAST AREA. ABOVE FREEZING TEMPERATURES
AT 850 MB WILL EXTEND OVER MUCH OF THE INTERIOR AND
MAYBE EVEN NORTHWESTWARD TO THE NORTHWEST ARCTIC COAST
BY WEDNESDAY AFTERNOON.

THE STRONG UPPER RIDGING AND WARM TEMPERATURES ALOFT
WILL UNDOUBTEDLY GENERATE DEEP AND STRONG INVERSIONS IN
THE INTERIOR...AND THIS IS CLEARLY EVIDENCED IN THE
PROG SOUNDINGS FROM THE GFS40 RUN.

SURFACE...
970 MB LOW APPROACHING THE EASTERN ALEUTIANS WILL
CURVE NORTHWESTWARD TO BE ABOUT HALFWAY BETWEEN
SAINT MATTHEW ISLAND AND THE PRIBILOFS BY SUNDAY
AFTERNOON.

SNOW SHOWERS AND N-NE WINDS TO 30-35 KT IN AKZ213
TONIGHT AND SUNDAY MAY COMBINE TO PRODUCE INTERMITTENT
LOW VISIBILITIES IN BLOWING SNOW. WINDS WILL PROBABLY NOT
BE STRONG ENOUGH TO PRODUCE SUSTAINED PERIODS OF POOR
VISIBILITY...THUS A WINTER WEATHER ADVISORY APPEARS ADEQUATE
TO HANDLE THIS SCENARIO.

SUB-ADVISORY GAP WINDS THROUGH WINDY AND ISABEL PASSES
WILL LIKELY CONTINUE THROUGH SUNDAY...BUT ISOLATED 50+
MPH GUSTS MAY OCCUR IN THE MOST WIND PRONE AREAS NEAR
THE NENANA RIVER CANYON. ANTLER CREEK RWIS CURRENTLY
REPORTING GUSTS 50+ MPH.

IN RESPONSE TO THE STRONG RIDGE BUILDING ALOFT...HIGH
PRESSURE OVER EASTERN RUSSIA WILL BUILD AND MOVE
EASTWARD INTO THE BEAUFORT SEA AND ARCTIC OCEAN
THROUGH EARLY NEXT WEEK. THE HIGH IS EXPECTED TO BUILD TO
AROUND 1050 MB BY TUESDAY EVENING. THIS WILL PRODUCE A
PRESSURE DIFFERENCE OF ALMOST 100 MB BETWEEN THE HIGH AND
950-955 MB STORM PROGGED TO MOVE NORTHEASTWARD INTO THE
SOUTHERN BERING SEA. THIS WILL LIKELY GENERATE WIDESPREAD
EASTERLY GALES OVER THE NORTHERN BERING SEA...CHUKCHI SEA...
AND PARTS OF THE WESTERN ARCTIC COAST. WINDS WILL APPROACH
GALE FORCE OVER NORTON AND KOTZEBUE SOUNDS. THERE IS A GOOD
LIKELIHOOD OF GROUND BLIZZARD CONDITIONS DEVELOPING OVER
PARTS OF THE WESTERN ARCTIC COAST TUESDAY NIGHT. WIND
PRONE AREAS SUCH AS POINT LAY WILL BE PARTICULARLY VULNERABLE.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
