Discussion
Relatively quiet weather is expected for today. The main issue
today will be the continued gusty northerly winds from the bering
strait south to st. Lawrence island. Overall, the models
initialize well and are in good agreement with the overall
synoptic scale pattern out through the
aloft, at 500 mb, the main feature of interest is a broad low
with two 497 dam centers that is currently located in the
southwestern portion of the forecast area. One center is located
just southwest of nunivak island and the other is located just
southwest of mcgrath. The center near nunivak island will move
east and weaken today. The center near mcgrath will move north
today, reaching galena by early Friday morning and near kotzebue
by Friday afternoon. Thereafter, the models begin to diverge some
on the track of the low; however, in general all of the models
have the low continuing off to the north.

Central and eastern interior: a front will bring snowfall as it
moves northward over the interior today. Up to one inch of snow
is expected east of nenana. West of nenana, the snowfall will
last a little bit longer, with up to two inches is possible. Any
snowfall will taper off from south to north overnight. The
temperature forecast for tonight will be somewhat tricky due to
expected variable cloud coverage behind the shortwave. The air
aloft over the area is cold enough to support temperatures around
20 below; however this will only happen if the sky clears. Likely
any clearing will be brief, so we won't go quite that cold for
most areas. A shortwave will move from southeast to northwest
across the interior late Friday into early Saturday bringing
another round of light snowfall. This feature should move through
rather quickly, so any accumulation is expected to be minimal at
this time.

North slope and brooks range: temperatures in the -20 to -30
range are currently being observed across much of the arctic
plain as well as along the beaufort sea coast. Winds are generally
less than 15 mph across the area so we are not making wind chill
advisory criteria at the moment; however a few locations have
been close. These cold temperatures are expected to continue for
tonight. A front will bring snowfall to the area on Friday into
Friday night as it moves north through the area. Around an inch
of accumulation is expected.

West coast and western interior: the main issue out west continue
to be the gusty northerly winds, snow and blowing snow from the
bering strait south to st. Lawrence island. Poor visibility
continue to be observed on both the coast of the bering strait as
well as on st. Lawrence island. North winds with gusts as 45 mph
are expected to continue today. I opted to extend the ongoing
winter weatehr advisory for zone 213 out into the afternoon. In
addition, the ongoing high surf advisory for north facing coasts
in zone 213 looks to be in good shape. Winds will decrease some
this evning as the surface low moves to the south. This will allow
the visibility to improve and the surf to diminish. Elsewhere, a
front will move to the north across the western interior bringing
around an inch of snow.

Coastal hazard potential days 3 and 4... None; however, see west
coast section above for issues in the shorter term.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
