.DISCUSSION...

ALOFT...A TROUGH WHICH HAS EXTENDED FROM THE ARCTIC OCEAN TO
BRISTOL BAY AND SOUTH OF THE ALEUTIANS DURING THE PAST SEVERAL DAYS
NOW ENCLOSES A CLOSED LOW. THE LOW COVERS MUCH OF THE AREA FROM
NORTH OF KOTZEBUE SOUND TO BRISTOL BAY AND IS EXPECTED TO DRIFT A
LITTLE EAST THROUGH WEDNESDAY. ON WEDNESDAY THE LOW WILL BE
CENTERED EAST OF THE NULATO HILLS AND EXTEND FROM BARROW TO THE
ALASKA PENINSULA. RIDGE OVER THE FAR WESTERN BERING SEA WILL
PERSIST THROUGH WEDNESDAY.

SURFACE...LOW PRESSURES OVER THE GULF OF ALASKA WILL BE FURTHER
EAST OVER THE NEXT FEW DAYS AS THE UPPER TROUGH DRIFTS EAST. LOW
PRESSURE WILL CONTINUE OVER THE GULF THROUGH MONDAY THEN MOVE EAST
OF THE SOUTHEASTERN INTERIOR MONDAY NIGHT. ANOTHER LOW WILL MOVE
NORTHEAST OF YAKUTAT TUESDAY NIGHT AND RAPIDLY EAST OVER CANADA
WEDNESDAY. A THIRD LOW COULD FOLLOW ON THURSDAY.

NORTH SLOPE...FLURRIES...FOG AND COLD TEMPERATURES WILL CONTINUE
THROUGH TUESDAY. WINDS WILL BE RELATIVELY LIGHT BUT WILL INCREASE
OUT OF THE EAST TUESDAY NIGHT. SOME WARMING MAY BEGIN MONDAY
NIGHT AND CONTINUE TUESDAY...EAST OF BARROW...BUT WILL COME TO AN
END AT MID WEEK AS LOW OVER WESTERN CANADA PULLS COLDER AIR BACK
SOUTH.

WEST COAST...NORTHEAST WINDS WILL CONTINUE OVER THE NEXT FEW DAYS AS
LOWS TRACK NORTHEAST OUT OF THE GULF OF ALASKA. WINDS ARE NOT
EXPECTED TO REACH ADVISORY LEVELS. PRECIPITATION WILL BE LIGHT.

INTERIOR...SYSTEMS MOVING NORTHEAST OUT OF THE GULF WILL BE
FURTHER EAST DURING THE NEXT SEVERAL DAYS...WHICH WILL MEAN MOST
OF THE ASSOCIATED SNOW WILL BE FURTHER EAST THAN IT HAS BEEN
LATELY. OVERRUNNING WILL PRODUCE SNOW FOR THE SOUTHEASTERN INTERIOR
AND EASTERN ALASKA RANGE AS LOWS MOVE NORTHEAST OUT OF THE GULF AND
INTO CANADA. ACCUMULATIONS MAY BE AS HIGH AS 3 INCHES OVER THE
EASTERN ALASKA RANGE FROM MONDAY TO MONDAY NIGHT WITH LESSOR
AMOUNTS TO THE NORTH AND WEST. FAIRBANKS TO THE WEST WILL HAVE A
CHANCE OF SNOW MONDAY AFTERNOON AND NIGHT ANY ACCUMULATIONS THAT
MAY OCCUR WOULD BE LESS THAN AN INCH. WINDS OVER THE EASTERN
ALASKA RANGE WILL BE A LITTLE GUSTY THROUGH PASSES TONIGHT AND
AGAIN MONDAY NIGHT BUT WILL PROBABLY NOT REACH ADVISORY LEVELS.
