.DISCUSSION...
THE MODELS ARE IN PRETTY GOOD AGREEMENT THROUGH SATURDAY EVENING.
THE UPPER AIR FEATURES A LONG WAVE PATTERN OF A DEEP TROUGH OVER
THE BERING AND NW PACIFIC AND A RIDGE OVER THE NE PACIFIC AND
EASTERN ALASKA. THIS WILL PERSIST THROUGH NEXT WEEK. THIS SOUTHWEST
FLOW ALOFT WILL CONTINUE TO BRING A SERIES OF STORMS OVER NORTHERN
ALASKA. THIS WILL ALSO CONTINUE THE ABOVE NORMAL TEMPERATURES AND
MOISTURE TO MOST OF NORTHERN ALASKA WITH CHINOOK WINDS IN THE
SOUTHEAST INTERIOR ACCOMPANYING EACH STORM.

THE 850 MB TEMPERATURES WILL RISE WITH THE NEXT FRONT COMING INTO
SOUTHWEST ALASKA SATURDAY BRINGING A CHANCE OF FREEZING RAIN
TO THE SOUTHWEST INTERIOR AND WEST COAST SOUTH OF THE BERING STRAIT.

AT THE SURFACE...A 1000 MB LOW 50 NM SOUTH OF BARROW WILL MOVE
NORTHEAST TO THE BEAUFORT SEA BY EARLY SAT MORNING...WEAKENING TO
1006 MB. A STRONG LOW IN THE SOUTHWEST BERING SEA WILL MOVE TO THE
THE CENTRAL BERING SEA AS A 955 MB LOW BY 3PM SAT AND THEN SLOWLY
WEAKEN. A WEATHER FRONT STRETCHING EAST FROM THIS LOW WILL MOVE TO
THE NORTHERN BERING SEA BY 3PM SAT AND INTO THE SOUTHERN CHUKCHI
SEA SUN. EXPECT GALES WITH THIS FRONT. EXPECT 4-8 INCHES OF SNOW
AND BLOWING SNOW ALONG THE WEST COAST ALONG THIS FRONT. THERE WILL
BE AREAS OF FREEZING RAIN WITH THE FRONT FROM THE BERING STRAIT
SOUTH AS WELL. SINCE TEMPERATURES ARE WARM BLIZZARD CONDITIONS
WILL NOT BE AS WIDESPREAD BUT WILL HAVE PLENTY OF WINTER HAZARDS
SO THERE ARE WINTER STORM WATCHES FOR WEST COAST AND SW INTERIOR
ZONES SOUTH OF THE BERING STRAIT.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
