Discussion
A relatively quiet weather pattern is expected for most of
northern alaska into the weekend with the main issue being
continued strong northerly winds from the bering strait south to
st. Lawrence island. Temperatures will be near or slightly below
normal in most areas into the weekend.

Models are in generally good agreement with the main track and
position of features the next few days. An upper low off the
southwest coast of alaska will lift north across the interior and
to the arctic coast by Saturday. This low will continue north on
Sunday as another upper low re-develops over southwest alaska. A
couple of weak troughs rotating around this upper low will
trigger some light snow and clouds over interior and arctic
alaska. A strong low moving into the northern gulf of alaska on
Sunday will likely push some warmer air north into the eastern
interior with colder temperatures persisting to the west.

Central and eastern interior... A colder airmass has settled over
the region which will bring more normal temperatures for mid-
december. Lingering clouds and a few snow showers associated with
a dissipating front from tanana to the yukon flats will diminish
this evening. Another weak weather front will move north across
the area Thursday and to the brooks range Thursday night. Most
locations will receive less than 1 inch of snow, except up to 2
inches is possible in the alaska range. Another weak trough may
bring a few snow showers on Friday. Temperatures will be the
trickiest forecast challenge due to the variable cloud cover. The
airmass aloft is cold enough to produce 20 below or colder
readings, but this will only occur in pockets where there are
breaks in the clouds.

West coast and western interior... Persistent northerly winds
25-35 mph with gusts up to 50 mph from the bering strait to saint
lawrence island continues to bring high surf to north facing
beaches along with low visibility in snow and blowing snow. The
ongoing advisory for high surf and winter weather will continue
through tonight. The strongest winds will start to diminish
Thursday, however, north winds 20 to 30 mph will continue into the
weekend. Some light snow will develop over the western interior
to norton sound on Thursday, with less than 1 inch accumulation
expected.

North slope... No significant weather expected the next several
days. Winds will generally be less than 15 mph in most locations
expect near CAPE lisburne. Patchy fog and a few flurries are
possible with a better chance for light snow on Friday as a
weather front moves north across the area. Temperatures will
remain well below zero with readings in the 10 to 35 below range.

Coastal hazard potential days 3 and 4... Continued northerly winds
from the bering strait to saint lawrence island, with winds
increasing significantly on Sunday.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
