.DISCUSSION...

UPPER AIR: TROUGH OVER BERING SEA TO NORTHERN PACIFIC WILL STEER
SHORTWAVE AND MOISTURE NORTHEAST OVER THE EASTERN BERING SEA AND
WEST COAST FOR THE REST OF THE WEEK. FOR THE UPCOMING WEEKEND...A
HIGH AMPLITUDE RIDGE EXTENDING NORTH OUT OF THE NORTHEAST PACIFIC
TO INTERIOR ALASKA APPEARS THAT IT WILL NOT BE AS HIGHLY AMPLIFIED
AND WILL ALSO BE FURTHER SOUTHEAST THAN THE PREVIOUS RUNS
SUGGESTED. THIS MEANS THAT MOISTURE COULD STREAM NORTH OVER THE
WEST COAST AND WEST INTERIOR FOR THE WEEKEND. THE EASTERN TO
SOUTHEASTERN INTERIOR SHOULD BE UNDER ENOUGH OF THE RIDGE TO KEEP IT
DRY THIS WEEKEND. AT LEAST ONE MORE RUN WILL BE NECESSARY TO SHOW
CONTINUITY.

SURFACE: LOW PRESSURE DEEPENING OVER THE CENTRAL ALEUTIANS WILL BE
966 MB AT 3 PM THIS AFTERNOON ABOUT 850 MILES SOUTHWEST OF NOME.
THE LOW WILL BE 971 MB 250 MILES SOUTH OF NOME...OR JUST NORTH OF
NUNIVAK ISLAND...AT 3 PM TUESDAY. AT 3 PM WEDNESDAY...THE LOW WILL
BE 1005 MB JUST EAST OF BUCKLAND. ANOTHER LOW MAY MOVE NORTH OVER
THE EASTERN BERING SEA SATURDAY THROUGH SUNDAY.

NORTH SLOPE: TEMPERATURES WILL REMAIN VERY COLD THROUGH TUESDAY
THEN A LITTLE WARMING WILL OCCUR AS BERING SEA LOW BEGINS TO TAKE
EFFECT. MODERATE EAST WINDS TUESDAY NIGHT WILL MAKE IT SEEM JUST
AS COLD IN SPITE OF THE WARMING. WINDS SHOULD BEGIN TO DIMINISH ON
WEDNESDAY. ONLY FLURRIES IF ANY PRECIPITATION AT ALL WILL OCCUR AS
A RESULT OF THE LOW PRESSURE. WINDS WILL RISE AGAIN THIS WEEKEND
AS ANOTHER BERING SEA LOW MOVES NORTH. THIS LOW WILL BRING WARMER
TEMPERATURES WITH MORE OF A CHANCE OF SNOW THAN THE PREVIOUS LOW.
NO WIND CHILL ADVISORIES ARE IN EFFECT THIS MORNING...BUT LIGHT
WINDS ARE JUST UNDER THE THRESHOLD FOR ZONES 203 AND 204.

WEST COAST: WINDS COMING UP AHEAD OF BERING SEA LOW WILL MIX WITH
VERY COLD AIR TO INITIALLY PRODUCE WIND CHILL ADVISORIES OVER
MUCH OF THE WEST COAST ZONES BEFORE TEMPERATURES WARM. BLIZZARD
WATCH IS STILL SET FOR LATE TONIGHT. THE GREATEST SNOW AMOUNTS
WILL BE OVER THE NULATO HILLS ON TUESDAY. WINDS AND SNOW WILL
DIMINISH ON WEDNESDAY. ANOTHER BERING SEA SYSTEM WILL OVERTAKE THE
WEST COAST ON SATURDAY.

INTERIOR: COLD WILL CONTINUE TODAY THEN WARMING WILL START OVER
HIGH TERRAIN TONIGHT AND WORK NORTHWARD. ON TUESDAY...WINDS WILL
MIX OUT COLD AIR IN VALLEYS AT MANY LOCATIONS. SNOWFALL TOTALS
TUESDAY THROUGH WEDNESDAY WILL BE GREATEST OVER THE WESTERN AND
NORTHERN INTERIOR...1 TO 3 INCHES. MUCH OF THE SOUTHEASTERN
INTERIOR WILL BE BLOCKED BY THE ALASKA RANGE. WINDS OVER THE
ALASKA RANGE WILL INCREASE TONIGHT AND TUESDAY ALONG WITH WARMER
TEMPERATURES. THIS SHOULD KEEP WIND CHILLS TO JUST BELOW ADVISORY.
DELTA JUNCTION WINDS WILL INCREASE THIS EVENING WITH WIND CHILLS
TO 55 BELOW. THURSDAY THROUGH FRIDAY WILL BE DRY...THEN SOUTHERLY
FLOW WILL TO EAST OF BERING SEA LOW WILL BRING IN MOISTURE OVER
THE WESTERN INTERIOR ON SATURDAY.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
