.DISCUSSION...

Models in decent agreement through 60 hours. 558 dam high center
just south of wrangel island will remain quasi stationary through
friday then sink south over the center of the state as a 555 high
center and persist into sunday. At 850 hpa...the fairbanks upper
air sounding is still minus 17 Celsius this morning. Models still
indicate that temperatures will slowly warm over the weekend and
into early next week.

surface...1055 MB high at the surface over the northern Yukon with
ridge axis stretching across the northern interior this morning.
High pressure will persist into sunday. Still seeing a very
strong pressure gradient in Northeastern Alaska producing gusty winds
over higher terrain. Wind chill advisory criteria has not been
met yet.

Interior...High pressure will continue its hold over the area.
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. The Tanana valley jet is blowing this
morning with gusts to 30 kts near delta junction. Winds will
persist into friday in that area. Overrunning light snow or
flurries south of chicken will persist through Thursday.

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