NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
714 AM AKST THU FEB 24 2011

.DISCUSSION...
THE COMPUTER WEATHER FORECAST MODELS ARE IN CLOSE AGREEMENT THIS
MORNING. THE LOW NOW IN THE EAST BEAUFORT SEA IS WEAKENING...BUT
STRONG HIGH PRESSURE OVER THE MAINLAND CONTINUES TO PRODUCE STRONG
WIND ON THE SOUTH SIDE OF THE LOW.

THE STORM NOW IN THE CENTRAL BERING SEA IS EXPECTED TO BRING HEAVY
WINDS...EXTENSIVE PRECIPITATION AND WIDESPREAD BLOWING SNOW AND
SOME BLIZZARD CONDITIONS TO ALL OF NORTHERN ALASKA OUTSIDE OF ZONES
223 AND 226...IN THE SOUTHEAST CORNER OF THE INTERIOR. THESE MAY
HAVE HEAVY SNOW FRIDAY NIGHT AND SATURDAY AS FAIRLY STRONG UPSLOPE
FLOW FROM THE NORTH DEVELOPS OVER THESE ZONES.

SATELLITE IMAGERY OVERNIGHT AND THIS MORNING SHOWS A HUGE AREA OF
VERY THICK CLOUDS OVER THE FRONTAL SYSTEM THAT THE STORM IN THE
CENTRAL BERING SEA HAS BROUGHT UP TO WESTERN ALASKA AND TO THE
EASTERN BERING SEA. THIS IS ONE INDICATION OF THE INTENSITY OF THE
INCOMING WEATHER.

THE INFLOW OF MID LATITUDE MARITIME FLOW HAS ORIGINATED FROM
AROUND TO 20 DEGREES NORTH LATITUDE. THIS STRONG INFLUX HAS DRIVEN
THE ARCTIC AIR NORTH OF BERING STRAIT AND UP OVER THE SOUTHWEST
MAINLAND. THIS...ALONG WITH WELL BELOW ZERO TEMPERATURES OVER
SIBERIA...IS A PATTERN FOR HEAVY WINTER WEATHER IN NORTHERN
ALASKA. THIS STORM IS EXPECTED TO PRODUCE MORE EXTENSIVE AND
HEAVIER WEATHER THAN ITS PREDECESSOR.

UNLIKE THE HEAVY SNOW ON THE 20TH AND 21ST...THE SNOW IN THE
INTERIOR WILL BE DIRECTLY ACCOMPANIED BY BRISK SOUTHWEST WINDS
TODAY AND TONIGHT. THESE WINDS WILL SHIFT TO THE NORTHWEST ON
FRIDAY. EXTENSIVE BLOWING SNOW IS EXPECTED NEARLY EVERYWHERE IN
THE REALM.

THE GFS FORECASTS THE ROUGH WEATHER TO END ON SATURDAY...AND THE
MEDIUM RANGE MODELS FORECAST A LARGE HIGH PRESSURE SYSTEM ALOFT TO
BUILD OVER THE BERING SEA STARTING SATURDAY...WHERE IT IS EXPECTED
TO HOLD PLACE THROUGH NEXT SATURDAY MARCH 5.
