Discussion
Light snow in the western interior and west coast, windy in the
alaska range and ground blizzard possible on the north slope
beginning Friday afternoon and continuing into Saturday morning.

Aloft at 500 hpa, a strong upper level ridge along a nome to great
slave lake line will persist into Saturday and will produce mostly
clear skies and limit precipitation for much of the central and
eastern interior through the weekend with much above normal
temperatures continuing into the weekend. Weak upper level low
pressure will continue over the eastern bering and gulf of alaska
through Saturday. A deep upper level low moves northeast into the
central bering sea on Sunday and through the bering strait late
Sunday night. A strong upper level low pushes north into the
southern bering sea on Monday.

A 1000 mb low pressure system over the interior combined with a
1032 mb high pressure system that builds east from wrangel island
today over the north slope Friday and Friday night will produce
strong winds and combined with recent snowfall along the north
slope will likely produce ground blizzard conditions along the
eastern north slope especially to the east of prudhoe bay and near
cape lisburne on the western north slope beginning Friday
afternoon and will continue into Saturday morning. Winter storm
watches have been issued for these areas.

Wind advisories continue for the eastern alaska range and for the
delta junction area as strong southerly winds aloft combined with
a weak mountain wave occasionally mix down to the surface. Expect
the mountain wave to dissipate later this morning and surface
winds to diminish as upper level winds diminish as well.

Mild chinook conditions over the southern portions of the central
and eastern interior will produce mostly clear skies and limited
precipitation through the weekend. High temperatures are expected
to reach the upper 40s to near 50 degrees from fairbanks south to
the alaska range through Sunday.

A slow moving front over the western interior today will continue
to push to the west over the west coast and western capes tonight
and will weaken as it continues to move west into the eastern
bering sea Friday morning. Less than an inch of snow is expected
in the western interior while 1 to 3 inches of snow is expected
over the west coast, the western capes and st lawrence island
through Saturday.

The 00z model suite initialized well against the 00z surface
analysis and verified well against the 06z surface analysis. Model
spread is reasonable through Saturday but begins to show
considerable spread by late in the weekend and into early next
week.

Coastal hazard potential days 3 and 4...

models continue to indicate the potential for a strong storm to
move into the western and central bering sea Monday, however there
remains significant differences in track and strength of the
storm. Several model solutions indicate the potential for
elevated water levels along the west coast early next week. We
will have to continue to monitor this system.

Afg watches warnings advisories

Winter weather advisory for akz213-akz214.

Winter storm watch for akz201-akz203-akz204.

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.
