NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
341 PM AKST TUE DEC 22 2009

.DISCUSSION...
NOT A LOT OF EXCITEMENT IN THE WEATHER OVER NORTHERN AK FOR THE
NEXT COUPLE OF DAYS. THE MODELS ARE IN GOOD AGREEMENT IN BUILDING
THE HIGH PRESENTLY CENTERED NEAR THE NORTH POLE SOUTH OVER THE
BEAUFORT SEA...WITH BRISK WINDS OVER THE ARCTIC COAST ABOUT
THURSDAY.

THE 970 MB LOW SOUTH OF CAPE NAVARIN WILL CONTINUE SOUTHWEST AND
WEAKEN. THE WEATHER FRONT ASSOCIATED WITH THIS LOW HAS DISSIPATED
OVER NORTHWEST AK AND THE SOUTHERN CHUKCHI SEA. 

THE MODELS ALL HAVE A SERIES OF SHORT WAVES MOVING NORTH OVER THE
GULF OF ALASKA FOR THE NEXT FEW DAYS. ONE OF THESE IS EXPECTED TO
HAVE A SURFACE CENTER OF ABOUT 984 MB EAST OF KODIAK AT 3AM WED.
THE SURFACE LOW DISSIPATES AS IT MOVES INLAND...BUT THE GFS AND
NAM BOTH USE THE SUPPORT ALOFT TO GIVE A BIT OF OVERRUNNING SNOW
IN ZONES 224 AND SOUTHEAST 220 WED NIGHT AND/OR THU. WE HAVE
GIVEN THIS SOME PLAY...THOUGH WE NOTE THAT THE ECMF IS WEAKENING
THE WAVE MORE RAPIDLY AND DOES NOT MANAGE TO GENERATE MEASURABLE
SNOW OVER NORTHERN AK FROM IT.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
