NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
325 PM AKDT WED OCT 29 2014

.DISCUSSION...
MODELS INITIALIZE IN DISAGREEMENT IN TERMS OF SURFACE FEATURES.
THEY ARE DOING BETTER WITH THE UPPER LEVEL FEATURES THOUGH...BUT
THEY HAVE BEEN INCONSISTENT EVEN BETWEEN THEMSELVES FROM RUN TO
RUN.

IN GENERAL...COLD UPPER LOW ABOUT 200 NM NORTH OF THE ARCTIC COAST
WILL PUSH EASTWARD TO BE ABOUT 300 NM NORTH OF DEMARCATION POINT.
THE COLD AIR WILL BE DRAGGED DOWN INTO NORTHERN ALASKA WHICH WILL
REMAIN OVER THE REGION THROUGH AT LEAST THE MIDDLE PART OF NEXT
WEEK. HIGH ALOFT WILL MOVE ACROSS THE ARCTIC COAST THROUGH NEXT
WEEK.

700 MB CLOSED LOW WILL MOVE NORTH THIS EVENING OVER THE CENTRAL
INTERIOR PROVIDING A FEW FLURRIES OR SNOW SHOWERS. WHICH WILL BE
MOSTLY CONFINED TO THE AREA EAST OF FAIRBANKS TONIGHT AND INTO
THURSDAY.

ANOTHER UPPER LEVEL LOW WILL MOVE UP THE ALASKA CANADA BORDER THU
NIGHT AND FRI AND PROVIDE MORE SIGNIFICANT SNOWFALL OVER THE FAR
EASTERN PORTION OF THE STATE...AGAIN EAST OF FAIRBANKS.

WINDS WILL INCREASE OVER THE WEST COAST ON FRIDAY AS A STRONG LOW
PULLS SOUTH OF THE ALEUTIANS FRI. THE UPPER LOW APPEARS TO
RESONATE IN BRISTOL BAY THROUGH THE WEEKEND.

THE MAIN CONCERN OVER THE NEXT WEEK IS JUST A MUCH COLDER REGIME
FOR NORTHERN ALASKA  THROUGH MUCH OF NEXT WEEK.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
