Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
213 PM AKST Wed Dec 7 2016

.DISCUSSION...
Models in decent agreement through 60 hours. Upper level ridge
firmly over the Bering Sea and West Coast. Upper level Omega Block
over West Coast will morph into a Rex Block by Saturday which the
subsidence will really warm up the upper level temperatures.

Overrunning snow in the far southeastern portion of the interior
around Northway and vicinity.

Scraps of stratus floating around the Arctic Slope will continue
to play havoc with the TAFs.

The very strong gradient with the strong surface high in
Northeastern Alaska and the low in the Gulf is producing winds on
some higher terrain. Wind chill advisory criteria has not been met
yet but something to watch for tonight and early Thursday but 850H
temps are warming so wind chills will not likely become an issue
after tonight even with the increased gradient.

In general...High pressure will continue its hold on Northern
Alaska. Strong surface based inversions will continue to form as
the lower level temperatures warm. Some winds will mix down to the
surface which will certainly produce temperatures differing
significantly over short distances.

Coastal Hazard Potential Days 3 and 4...None.
