Discussion
A relatively quiet pattern is expected for most of northern
alaksa over the next few days with the main issue being continued
strong northerly winds from the bering strait south to st.

Lawrence island.

Aloft, at 500 mb, a 492 dam low is currently just west of nunivak
island and will be the main feature of note over the next few
days. This low will push to the east today, moving over the lower
yukon valley tonight. The low will make a northward turn on
Thursday, moving into the central interior by Thursday night,
after Thursday night, the models begin to diverge on the exact
track of the low; however, generally, the models have the low
tracking northward over the brooks range on Friday and reaching
the arctic coast Friday night.

Central and eastern interior: a front that brought snow to the
fairbanks area Tuesday evening will continue to move to the
northwest today. The front will fall apart today; however, it
could bring up to an inch of snowfall today to areas northwest of
fairbanks. A shortwave will move north across the interior on
Thursday. This will bring some snowfall; however, at this point we
expect accumulations to be relatively light, mainly under one
inch. Snowfall will taper off from south Thursday evening. Right
now we aren't expecting any precipitation for Friday. The biggest
issue for Friday will be the low temperatures. Current guidance
suggests that Friday will be the coldest day so far this season
for fairbanks with some models suggesting a temperatures as cold
as -20. The temperature forecast will be a bit tricky. The cold
temperatures will only be realized if the skies clear out behind
the shortwave. Currently it looks like the clearing will be
somewhat brief so we won't go with the coldest of guidance right
now for Friday morning. There is potential another shortwave to
pass from southeast to northwest across the interior on Saturday
bringing additional snowfall; however at this point the models
don't agree on this.

North slope and brooks range: I opted to cancel the inherited
wind chill advisories for zones 201 and 206. While the temperatures
in these areas are still quite cold, the winds have dropped off
enough to be below advisory criteria. Temperatures across much of
the arctic plain away from the coast will reach -25 to -35
tonight. Temperatures along the beaufort sea coast (especially
around deadhorse will reach near -25 tonight with similar
temperatures expected for Thursday and Friday nights.

West coast and western interior: northerly winds with gusts as
high as 50 mph will continue today from the bering strait south to
st lawrence island. This will cause high surf for the the north
side of st. Lawrence island as well as little diomede. The ongoing
high surf advisory for zone 213 is in good shape. A band of
heavier snowfall will pass over st. Lawrence island this morning.

This snowfall, when combined with the strong winds, will produce
blowing snow that will reduce the visibility to one half mile or
less at times. The ongoing winter weather advisory looks to be in
good shape. As the surface low moves to the south tonight, winds
through the bering strait will diminish some; however, gusty
northerly winds will persist through the end of the week.

Coastal hazard potential days 3 and 4... See west coast section
above.

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

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.
