.DISCUSSION...
CURRENT MODELS AND ENSEMBLE MEANS INDICATING A COLD UPPER LOW
WILL BE THE CONTROLLING FEATURE OVER NRN AK FOR THE NEXT WEEK.
WITH THE CYCLONIC FLOW ALOFT...SKIES ARE LIKELY TO REMAIN
MOSTLY CLOUDY OVER MOST AREAS FOR MOST OF THE TIME AND THIS
SHOULD KEEP INTERIOR TEMPERATURES OUT OF THE EXTREME COLD
RANGE. HOWEVER...COLDER TEMPERATURES WILL BE POSSIBLE IN ANY
AREAS WITH CLEAR OR PARTLY CLOUDY SKIES.

MESOSCALE RIDGE HAS DEVELOPED OVER THE INTERIOR ARCTIC
SLOPE AND IS LIKELY TO PERSIST FOR AT LEAST A FEW DAYS.
THIS WILL LIKELY KEEP WINDS OUT OF THE WEST TO SOUTHWEST
ALONG THE CENTRAL AND EASTERN ARCTIC COAST. TYPICALLY...
MODELS TEND TO DISSIPATE THIS FEATURE TOO QUICKLY. NORTHEAST
WINDS DEVELOPING ALONG THE WESTERN ARCTIC COAST WILL LIKELY
BE LESS THAN MODEL FORECASTS...SO WILL WE WILL NOT UP ANY
WIND CHILL ADVISORIES FOR THE WESTERN ARCTIC ZONES.

LOW WIND CHILL IN ZONE 207 WILL LIKELY BE LIMITED TO
AREAS NORTHWEST OF KIVALINA...WHILE IN ZONE 213...LOW
WIND CHILL IS EXPECTED TO BE LIMITED TO AREAS NEAR
THE BERING STRAIT.

COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
