Discussion
Synopsis... Going to be pretty quiet across the area into the
weekend, however winds do pick up near the alaska range, in the
tanana valley, and over summits in the interior. The winds will
create blowing snow with reduced visibilities on summits at times
through Friday. A weather front is moving across the arctic, but
not much to it. Look for increasing clouds along the arctic coast
as trough drags east and high moves to the central arctic with
onshore flow developing. Inverted trough over the eastern bering
sea will spin some clouds and showers up the west coast tonight
through Friday.

Models... Run to run continuity in the solutions has been good in
the short term. Solutions continue to struggle past 48 hours, and
there is a lot of divergence beyond 96 hours. Surface solutions
suffer the same issues. 15 00z solutions did initialize well
against the 15 06z surface analysis. Will use a pretty equal
blend for the short term with a lean to the NAM for winds, except
for the coastal and marine areas a lean toward the GFS winds.

Aloft... At 500 dam... Fast northwest to southeast flow has
developed over the arctic as a 547 dam high has moved from
chukotka to anaktuvuk pass and is merging with ridging that
extends northwest to norton sound from a high off the california
coast. Troughing lies to the west of the ridge with a 528 dam low
over the mouth of the gulf of anadyr, and a 535 dam low 400 nm
south of sand point. The fast flow over the arctic will continue
as the high merges with the ridging and the ridge will extend from
off the california coast to cordova to point lay, then west along
70n. Troughing will slide east a bit to lie from 200 nm west of st
matthew island to toksook bay to a 541 dam low near chignik. By
Friday night the trough is being squeezed out as ridging over the
state slides east to lie over the southeast panhandle to nuiqsut
then north. Another branch of the ridge rotating through puts the
squeeze on the trough and the decaying low moves through the ridge
over the yukon territory as the ridging merges into one. Troughing
over the bering sea will extend from a 520 dam low over the gulf
of anadyr to a 521 dam low over st paul island to a 529 dam low
200 nm south of dutch harbor. The fast flow over the arctic will
become more zonal as the ridge builds over mainland alaska. At
850 dam... Temperatures have warmed to 0c to -10c over most of the
forecast areas this morning with a pocket of temperatures
slightly above 0c over the lower yukon delta. Temperatures do not
change much through Saturday except for the middle and lower yukon
delta temperatures rise a couple degrees.

Surface... A ridge of high pressure lies east to west from the
north central yukon territory west along the south slopes of the
brooks range, and across the chukchi sea. Inverted trough over the
eastern bering sea continues to spin some showers north up the
coast. And, a weak weather front will move east across the arctic
today. By Saturday morning the high pressure will lie over the
northeast half of mainland alaska and west across the arctic from
a 1031 mb high 200 nm north of demarcation point. A trough will
persist to the southwest. The trough consists of a 1006 mb low 200
nm north of st paul extending southeast to a 1002 mb low over the
alaska peninsula, to a 996 mb low 200 nm southeast of sand point.

Leeside troughing will develop north of the brooks range Friday.

Arctic coast and brooks range... Most areas are clear to partly
cloudy this morning, but high pressure will be moving in behind a
weak weather front and winds will swing around from southwest to
northeast to east through the afternoon and tonight. With the
onshore flow stratus developing along the coast extending inland
up to 10 miles before is breaks up a bit. Winds 5 to 15 mph
becoming 5 to 10 mph when they swing around. Increasing winds on
Friday to 10 to 20 mph. Temperatures slightly cooler.

West coast and western interior... Some increasing clouds today,
then showers slowly spreading north up the coast. 2 to 3 inches of
new snow can be expected by Saturday morning in most areas with
some heavier amounts in the nulato hills, and bendeleben mountains
on the seward peninsula. Winds generally northeast to east at 5
to 20 mph.

Central and eastern interior... Snow lingering flurries in the
central interior around tanana and manley hot springs will end
this morning. Mostly clear for the remainder of the area with
clearing after the snow ends. Temperatures will be cooler and
tonight, but warmer Friday in the middle tanana valley as leeside
trough north of the alaska range helps develop some gap winds.

Gusty winds around delta junction, and over interior summits with
some local areas of blowing snow.

Extended forecast for days 4 to 7... A low will persist over the
west coast with increased chances of snow each day. A weather
front will push north over the alaska range Sunday night and move
northeast across the interior spreading snow with 2 to 4 inches
of snow Monday morning through Tuesday evening.

Coastal hazard potential days 3 and 4... None.

Afg watches warnings advisories
Heavy freezing spray warning for pkz200-pkz215-pkz220.

Small craft advisory for pkz200-pkz210.

Brisk wind advisory for pkz235.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
