Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
339 PM AKDT Tue Apr 25 2017

.DISCUSSION...
Models in decent agreement through 60 hours in terms of synoptic
features. Upper level trough with surface reflected cold front is
pushing southeastward from the northwest Arctic. Most of the cold
air will remain north of the Brooks Range but some cooler air will
push southward to the Alaska Range and mitigate some of the very
warm conditions that are occurring over much of the Northern
Interior. This will push the upper level ridge back into Canada
that is extending up from the southeast and Panhandle of Alaska.

A washed out occluded front is interacting with the cold front and
producing some light showers over the Interior. The cooler
temperatures will hold over the Interior through probably Sunday.
Some moderation but not a lot.

The large stratus shield over Arctic Coast is fairly uniform in
base height with some light snow showers accompanying the stratus
shield. A surface high will build in over the Arctic Coast behind
the cold front Tuesday night.

Winds in the Alaska Range have increased today with the thermal
low and thermal trough over the area. But the winds should be
subsiding by tonight as the gradient relaxes a bit.

.FIRE WEATHER...
Winds have increased in the Eastern Alaska Range and RH values
have dropped into the 20s s things are beginning to dry out in the
Eastern Interior where the snow is now gone.
