Northern Alaska forecast discussion 
National Weather Service Fairbanks Alaska
314 PM akdt Thursday Sep 29 2016

Discussion...the models are fairly good agreement through next
96 hours which allows for greater confidence. The overall upper
level weather pattern has high pressure ridge building over much
of northern and interior Alaska through the weekend as an Arctic
low pressure quickly moves eastward across the Beaufort Sea by
Friday night. However, over the West Coast there will be a wet
pattern and stronger south to southeast flow approaching as an
upper level low moves toward Bristol Bay. This will bring
precipitation to the West Coast and the stronger surface pressure
gradient will bring stronger winds south to southeast winds.

Arctic coast and Brooks range...a weak disturbance will move east
across the area tonight through Friday bringing a period of rain
showers particularly along Barrow tonight and through the eastern
Beaufort coast and eastern Brooks range by Friday. As the high
pressure builds behind on Friday night and Saturday, the
temperatures will start to warm along the coast. Expect high
temperatures reaching into 40s and inland areas in the 50s. Low
temperatures will still fall to around freezing at night with the
clearing skies.

West Coast and western interior...although the high surf will
begin to taper over the West Coast, still expect the winds to
remain relatively strong. Marine areas expect gale and small
craft advisories to continue through the weekend along the Bering
Strait and Chukchi Sea. Thus can expect above normal wave action
to continue across the area through the weekend as well. Could
potentially see some fog development over the Yukon Delta area
again on Friday morning, so mentioned fog in forecast. The next
front will spread showers to the West Coast on Friday but should
keep the western interior clear. A low moving north on Saturday
will spread another round of showers over the Yukon Delta area and
spreading northward through Sunday.

Central and eastern interior...ridge building over the area will
bring mostly clear skies and warmer temperatures for the
weekend. Main concern for tonight will be how quickly we can clear
the skies. Already starting to see some punches of sun through the
clouds. We are expecting clearing skies for a very chilly morning
on Friday in the interior then warm up nicely for Friday
afternoon and Saturday before a slight cooling trend starting
Sunday. Only other concern for tomorrow morning will be the fog
that is hanging near and north of McGrath. Will keep the fog
visibility to a mile or less at times for Friday morning as well
but should clear up by mid morning. Gap winds will increase to
gusting to 45 mph Saturday through Alaska Range passes as leeside
troughing develops in the interior.

Coastal hazard potential days 3 and 4...moderately strong
southeast winds over the coastal areas through the weekend will
produce some elevated wave action, but no issues are anticipated.
