TUESDAY...MODERATE SOUTHWESTERLY WINDS ALOFT WILL DEVELOP OVER ALL
OF NORTHERN ALASKA. THIS WILL BE FOLLOWED BY GRADUALLY WEAKENING
SOUTHERLY FLOW ALOFT WEDNESDAY. FROM THURSDAY THROUGH
SATURDAY...AS THE TROUGH ALOFT MOVES EASTWARD INTO THE
YUKON...MODERATE NORTH WINDS ALOFT WILL DEVELOP OVER NORTHERN
ALASKA. THE ORIGIN OF THESE NORTH WINDS ALOFT WILL BE IN THE VERY
HIGH ARCTIC.

TEMPERATURES ALOFT WILL BE QUITE COLD...EXCEPT FOR A BRIEF
REMISSION FROM TUESDAY AND WEDNESDAY WHEN SOUTHWEST WINDS ALOFT
BRING IN MORE MODERATE TEMPERATURES TO THE INTERIOR. ON THURSDAY
THROUGH NEXT TUESDAY / JANUARY 12 THROUGH JANUARY 17 /...NORTH
WINDS ALOFT WILL CONTINUE AN INFLUX OF COLD ARCTIC AIR OVER THE
REALM. IN THIS PATTERN OF WIND FLOW ALOFT...THE MILDEST

PREVAILS OVER ALL OF THE REALM ON MONDAY AND TUESDAY...THE WESTERN
MAINLAND WILL BECOME CLOUDY AND HAVE SOME LIGHT SNOW. THE ARCTIC
ORIGIN OF THE INBOUND FLOW STARTING ON WEDNESDAY WILL RESULT IN
LITTLE SNOWFALL FROM THIS THURSDAY INTO NEXT WEEK.

A MODERATE NORTH PACIFIC LOW PRESSURE SYSTEM HEADED TOWARD THE
ALASKA PENINSULA WILL BRING INCREASING NORTH WINDS TO THE BERING
SEA COAST AND THE WESTERN INTERIOR STARTING ON TUESDAY.
