NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
1141 AM AKST THU FEB 9 2012

.DISCUSSION...
S TO SE FLOW ALOFT WILL CONTINUE OVER MUCH OF NRN AK THROUGH
SUN NIGHT. SERIES OF SHORT WAVES MOVING UP THE WEST COAST WILL
PRODUCE SEVERAL PERIODS OF SNOW OR SNOW SHOWERS DURING THE TIME
RANGE TONIGHT THROUGH MON NIGHT. A WEAK SHORTWAVE EMBEDDED IN THE
FLOW ACROSS THE CENTRAL/EASTERN INTERIOR COULD SET OFF SOME SPOTTY
PRECIPITATION OVER PARTS OF THE CENTRAL/EASTERN INTERIOR FRI AND
FRI NIGHT. DOWNSLOPE FLOW SHOULD KEEP SOUTHERN INTERIOR AREAS DRY.

IN THE MEDIUM RANGE...THE CONTROLLING FEATURES ARE A LARGE
MEAN ELONGATED UPPER LOW EXTENDING FROM NE ASIA THROUGH SW
ALASKA...AND A MEAN UPPER RIDGE OVER NW CANADA AND ACROSS
NRN ALASKA. SEVERAL SHORTWAVES WILL PROGRESS THROUGH THIS
FLOW BUT THERE IS LOW CONFIDENCE IN THE TIMING OF INDIVIDUAL
SHORT WAVES. OVERALL...THIS PATTERN WILL MAINTAIN THE MUCH
MILDER CONDITIONS OVER THE FORECAST AREA.
