NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
154 PM AKST MON JAN 17 2011

.DISCUSSION...
DEEP COLD LOW ALOFT CENTERED NR 78N/140W WILL BE OVER ERN BANKS
ISLAND BY TUE AFTERNOON. ASSCD COLD FRONT PUSHED ACROSS THE BROOKS
RANGE THIS MORNING WITH HIGH PRES BUILDING ON THE NORTH SLOPE.
MEANWHILE...932 MB LOW SW OF SHEMYA NOW WEAKENING AND WILL REMAIN
JUST SOUTH OF THE ALEUTIANS BUT THE ASSCD OCCLUSION WILL MOVE INTO
THE CENTRAL BEING SEA TUE NIGHT. REMNANTS OF THE MEGA HIGH ALOFT
STILL EXTEND FROM CENTRAL SIBERIA ESEWD INTO SW ALASKA.

MODEL GUIDANCE IN DECENT AGREEMENT ON THE OVERALL PATTERN THROUGH
THIS WEEK...THO SOME DETAILS DIFFER. IN THE MID RANGE...HOW FAR
NORTH THE SOUTHERN FLOW CAN GET WILL BE AN IMPORTANT ISSUE FOR
TEMPS AND ANY SNOW...THOUGH GIVEN MOST OF THE CWA REMAINS IN A
SNOW DROUGHT...PERSISTENCE WOULD FAVOR DRIER SOLUTIONS.

NORTH SLOPE...COLDEST AIR REMAINS NORTH OF THE BEAUFORT SEA COAST
BUT STILL A SUBSTANTIAL COOL DOWN UNDERWAY...AND THE SLOPE LOOKS
TO REMAIN IN BROAD CRCLN OF THE COLD LOW ALOFT ALL WEEK.

WEST COAST...WINDS INCREASING TUE AS OCCLUSION MOVES THRU THE
BERING SEA. SNOW THO LOOKS UNLIKELY TO GET NORTH OF THE YUKON
DELTA. TEMPS MODERATING A BIT BUT PRETTY SHARP N-S GRADIENT
PERSISTING.

INTERIOR...CLOUDS WITH WEAKENING COLD FRONT HAVE BEEN SOMEWHAT
BROKEN UP CROSSING THE BROOKS RANGE AND SLIGHTLY MODIFYING VALLEY
TEMPS. MEANWHILE...SC ACROSS THE ALASKA RANGE/SRN INTERIOR HAVE
BEEN PERSISTING...AND EVEN GROWING ACROSS ZONE 224. THESE ARE
HAVING A MORE SIGNIFICANT IMPACT ON TEMPS. INCREASING W-NW FLOW
ALOFT SHOULD HELP CLEAR THESE OUT NEXT 18 HOURS.
