NATIONAL WEATHER SERVICE FAIRBANKS AK
304 AM AKST FRI FEB 18 2011

.DISCUSSION...

.DISCUSSION...
976 MB LOW ABOUT 100 MILES EAST OF WRANGEL ISLAND AT 06Z
THU IS PROGGED BY GFS/NAM TO MOVE TO AROUND 300 NM NORTH
NORTHWEST OF BARROW BY 12Z SAT FILLING TO 985-988 MB.
GEM/EUROPEAN MODELS ARE REASONABLY SIMILAR ON POSITION
BUT A FEW MB DEEPER ON CENTRAL PRESSURE AT 12Z SAT.
ASSOCIATED UPPER LOW NEAR WRANGEL ISLAND IS VERTICALLY
STACKED WITH THE SURFACE LOW.

NEXT SHORT WAVE ALOFT NOW WEST OF THE GULF OF ANADYR
IS PROGGED BY ALL MODELS TO MOVE TO THE WEST COAST OF
AK BY 12Z SAT...THEN TO E OF THE ALCAN BORDER BY 12Z SUN.
THIS FEATURE WILL BRING ANOTHER PERIOD OF SNOW TO MOST OF
NORTHERN ALASKA FROM THE BROOKS RANGE SOUTHWARD AS IT
TRANSITS EASTWARD...BUT STRONG WINDS ARE NOT EXPECTED.

A SHORT WAVE RIDGE WILL FOLLOW BUT BE REPLACED BY A FLAT
WESTERLY FLOW OVER THE STATE BY 00Z MON. CURRENT MODEL
RUNS AGREE FAIRLY WELL ON THE NEXT INCOMING STORM...
SURFACE LOW AROUND 976 MB JUST WEST OF THE GULF OF ANADYR
BY 12Z SUN. THIS IS LIKELY TO BE ANOTHER BLIZZARD EVENT...SNOW
AND STRONG SOUTH TO SOUTHEAST WINDS BEGINNING OVER ST LAWRENCE
ISLAND SAT EVENING...SPREADING TO WEST COAST AREAS LATER SAT
NIGHT. WATCHES FOR WEATHER ASSOCIATED WITH SYSTEM WILL LIKELY
BE ISSUED THIS AFTERNOON.

IN THE SHORT TERM...BLIZZARD CONDITIONS HAVE ENDED
OVER ALL WEST COAST AREAS. SNOW SHOWERS WILL CONTINUE
OVER ZONES 207-208-209

BRISK SOUTH TO SOUTHWEST WINDS DEVELOPING TODAY IN ZONES
201-202-203-205 AND IN ZONE 206 PASSES AS THE SURFACE
LOW LIFTS NORTHEASTWARD INTO THE ARCTIC. BLOWING SNOW
WILL REDUCE VISIBILITY IN THESE AREAS.

EXCEPT FOR ZONE 226 AND PARTS OF ZONE 223...SNOW AMOUNTS
