NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
439 AM AST FRI FEB 29 2008

.DISCUSSION...
UPPER LEVEL LOW HAS MOVED SOUTH FROM THE HIGH ARCTIC AS PREVIOUSLY
THOUGHT. CURRENTLY POSITIONED JUST EAST OF MACKENZIE BAY. DECENT
COLD ADVECTION NOW OCCURRING WITH ARCTIC FRONT AS IT SLIDES
SOUTHWARD OVER THE STATE.

CURRENTLY...IT APPEARS THAT THE FRONT IS OUTRUNNING THE GRADIENT
PACKING. IF THIS CONTINUES THEN THE INTERIOR WIND CHILLS MAY NOT
MATERIALIZE AS WELL AS PREVIOUSLY THOUGHT. WINDS WILL CONTINUE TO
BE MODERATELY STRONG THROUGH PASSES IN THE BROOKS RANGE THROUGH TONIGHT.

EXPECT WINDS TO DIMINISH IN EASTERN ARCTIC LATER THIS AFTERNOON AS
THE MAJORITY OF THE COLD ADVECTION WILL HAVE PUSHED THROUGH BY THEN.

COLD AIR WILL REMAIN OVER MUCH OF NORTHERN ALASKA THROUGH THE
WEEKEND AS UPPER LEVEL TROUGH DIGS SOUTHWEST TO THE YUKON
KUSKOKWIM DELTA THROUGH SATURDAY. AN UPPER LEVEL COLD BALL LOW
WILL SLIDE DOWN THE TROUGH AND BE IN BRISTOL BAY BY SATURDAY
AFTERNOON. THIS LOW WILL JUST PIN WHEEL FOR SEVERAL DAYS.

UPPER HIGH OVER FAR EASTERN RUSSIA WILL RETROGRADE BACK WEST
THROUGH THE MIDDLE PART OF THE WEEK AS UPPER LEVEL RIDGE BUILDS IN
FROM THE SOUTH OVER MOST ALL OF ALASKA. THIS WILL CAUSE
TEMPERATURES TO SOAR IN MOST OF THE STATE BY THE MIDDLE OF THE
WEEK. THESE CONDITIONS WILL LIKELY HOLD ON FOR THE REMAINDER OF
THE WEEK. INTERIOR TEMPERATURES WILL LIKELY SEE AMBIENT AIR
TEMPERATURES CLIMB TO NEAR FREEZING AGAIN AND WITH THE SET UP OF
THE UPPER LEVEL RIDGE CAUSING SOME DOWNSLOPE...ABOVE FREEZING
TEMPERATURES MAY BE SEEN AS WELL STARTING AROUND TUESDAY.
