Discussion
Clearing and colder in the interior and less wind over the west
coast and bering strait.

Aloft at 500 mb, a weak trough will migrate east as an upper level
high pressure center over siberia merges with a ridge of high
pressure building north out of the gulf of alaska over western
alaska. As the two high pressure systems merge, clouds will
dissipate and will cause the temperatures in the interior to
dramatically drop tonight and remain cool into Friday before
clouds ahead of a front moving northeast out of the yk delta into
the western interior late Friday and into the central interior
Saturday.

On the surface a 1032 mb high pressure system over the northern
yukon will push a much colder airmass into the interior tonight
that will remain in place into Saturday with 30s below in the
interior portions of the north slope, and the yukon flats.

Temperatures in the southern interior will depend greatly on both
cloud cover and local northeast drainage winds making the
difference between single digits below and 20s below.

A weak trough will persist over the eastern bering sea and will
deepen as a low in the northern pacific moves north to be located
300 nm south of kodiak island Friday morning as a 996 mb low and
near cold bay as a 1000 mb Friday night. This low will weaken and
be absorbed by a 990 mb low moving northeast along the aleutian
chain on Saturday. This new low will continue move into bristol
bay as a 986 mb low Saturday night.

Arctic coast and brooks range... Mix of clouds and fog as well as
areas of partly cloudy skies will continue tonight and into
Friday. Winds southwest at 10 to 20 mph along the coast with
light winds in most of the brooks range. Temperatures will be
cooler the next couple days, then warm slightly.

West coast and western interior... Mostly clear along the coast
with offshore flow will transition to southerly flow as a front
moves north along the coast tomorrow afternoon and tomorrow night.

Winds will remain gusty north of the seward peninsula and through
the bering strait to around 40 mph. Inland some clouds this
evening will begin to clear by morning. Temperatures cooler the
next couple days.

Central and eastern interior... Flurries will taper off this
evening with clearing expected after midnight tonight.

Temperatures will fall dramatically with lows in the -5 to -25
range around fairbanks, with slightly cooler temperatures to the
north and slightly warmer temperatures to the south. Winds around
delta junction will increase Friday night as tanana valley jet
kicks in and winds gust to around 35 mph.

Models, the 12z model suite initialized well against the 12z
surface analysis and verified well against the 18z surface
analysis. Model spread is minimal through the end of the week and
begins to increase significantly by the first part of next week.

Extended forecast for days 4 to 7... Temperatures will warm
slightly with increasing chances of snow on the west coast and
across the interior. The arctic will not see much change with
generally cloudy conditions with periods of light snow and areas
of fog.

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

Afg watches warnings advisories
Heavy freezing spray warning for pkz200-pkz210-pkz215-pkz220-
pkz230.

Small craft advisory for pkz200-pkz210-pkz235.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
