NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
329 PM AKST WED JAN 28 2015

.DISCUSSION...
MODELS IN DECENT AGREEMENT THROUGH ABOUT 60 HOURS. COLD UPPER
LEVEL TROUGH WILL CONTINUE TO LIFT NORTHEAST THROUGH FRIDAY
MORNING. LARGE UPPER LEVEL RIDGE OVER THE CENTRAL BERING SE WILL
MOVE EASTWARD AND ORIENT ITSELF TO A MORE WEST TO EAST RIDGE BY
EARLY SATURDAY.

AS THE TROUGH MOVES OVER NORTHERN ALASKA IT WILL CUTOFF THE LOW IN
THE NORTHERN PACIFIC. THE RIDGE WILL CONNECT UP TO THE UPPER RIDGE
ON THE EAST SIDE OF THE LOW SO THAT THE RIDGE WILL ORIENT FROM A
SOUTHEAST TO NORTHWEST CONFIGURATION.

SHORTWAVE TROUGH AHEAD OF THE UPPER LEVEL RIDGE MOVING EAST OVER
NORTHERN ALASKA ON FRIDAY WILL LIKELY PRODUCE SOME SNOWFALL AND
BLOWING SNOW OVER NORTHWEST ARCTIC COAST ON FRIDAY. THE FRONT WILL
SPREAD O THE BROOKS RANGE AND PRODUCE SOME SNOWFALL ALONG THE
NORTHERN SLOPES OF THE BROOKS RANGE THROUGH SATURDAY.

THE GFS ADVERTISES ANOTHER COLD SHORT WAVE MOVING INTO NORTHWEST
ARCTIC COAST BY NEXT TUESDAY. THIS MAY SEND SOME VERY COLD AIR
INTO THE NORTHERN ALASKA AGAIN AND ALTHOUGH THIS IS NEARLY 180
HOURS INTO THE FUTURE IT HAS MANY CHARACTERISTICS OF THE HEAVY
SNOWFALL THAT RECENTLY OCCURRED OVER THE MIDDLE TANANA VALLEY
FOLLOWED BY THE COLDEST AIR OF THE SEASON TO INFILTRATE NORTHERN
ALASKA. STAY TUNED FOR THIS ONE.
