.DISCUSSION...
An Arctic cold front over the fire will move north today.

A thermal low pressure trough over the Alaska Range will move north
to just south of the fire tonight. Temperatures will warm to the
upper 50s and lower 60s with RH falling to 20-30 percent along this
feature today.

A strong low in the Southern Bering Sea will move to the southeast
Bering Sea tonight, into Bristol Bay on Sat and into the Gulf of
Alaska on Sun. This will cause southerly Chinook winds develop
across the Alaska Range starting late today then continuing into Sat,
then decrease Sat night.  This will bringing dry, windy and warm
conditions to the Tanana Valley this evening through Sat night.

Isolated to scattered showers are expected over most of the
Eastern Interior on Sun as the Chinook ends.
