Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
158 AM AKDT Tue Apr 11 2017

.DISCUSSION...

The 00z model suite initialized well against the 00z surface
analysis and verified well against the 06z surface analysis. Model
spread remains minimal between model runs and between model
families in the short range as well as the mid range. Model spread
in the long range increases but is still very reasonable.

Aloft, at 500 hpa a shortwave along a wrangle Island to Point Hope
line rapidly lifts to the northeast as a strong upper level ridge
builds rapidly north and east into the eastern Bering Sea today
and continues to build and cut off into a closed upper level high
pressure system positioned over central Alaska by Wednesday
afternoon. The upper level high pressure system remains in place
Thursday but begins to retreat south and west over southwest
Alaska as a strong shortwave along the southern portion of a
unseasonable cold upper level trough dives south and southwest out
of the high canadian arctic into northeast Alaska Friday and into
eastern Alaska and the Yukon Saturday. 850 mb temperatures over
Fairbanks drop from around 4 below Friday to around 8 below
Saturday and around 12 below Sunday morning. 850 mb temperatures
slowly rebound back to around 4 below by the middle of next week.

On the surface, mostly dry conditions are expected over the
western and central interior and only occasional snow flurries
over the eastern interior through the week however as the cold
front dives south and west out of the norther Yukon Friday night
and Saturday a period of light snow or flurries will be possible
over the eastern and flurries over the central interior. A strong
high pressure around 1043 mb builds south out of the high arctic
as a 1000 mb low spins in the gulf of Alaska next weekend
producing a tight gradient over the north slope, the brooks range
as well as the northern interior.

On the north slope low ceilings are widespread. Areas of fog
continue as well on the north slope. Winds continue to increase in
the Bering Sea ahead of a 970 mb low over the western Aleutians.
Winds will increase to Gale force in the waters around St
Lawerence this evening with wind gusts increasing to around 50
mph tonight over St Lawrence Island with scattered snow showers
developing after midnight. Continue to monitor for winter weather
headline potential late tonight and Wednesday on St Lawrence
Island as winds combined with falling snow will take visibility
down to near one half mile at times. The low rapidly weakens and
the front stretches apart Wednesday night and Thursday morning as
the front fails to make it ashore on the Alaska west coast with
strong high pressure diving south out of the high arctic onto the
north slope late Thursday and into the alaska interior Friday.
