Synopsis
Aloft...

a long wave trough over mainland alaska will retrograde to the
west coast of alaska and eastern bering sea by Thu then remain
there through the weekend into next week. The long wave ridge over
nw canada will build into eastern alaska on the weekend and
persist into next week. This pattern change is setting up
northern alaska for a much warmer and more active weather pattern
as flow aloft turns southerly and increases from Thu into the
weekend.

Several short wave troughs will drop from north of the russian
coast over the west coast of alaska and into the long wave
trough over the next few days. The first trough will move south
over the chukchi sea today and to the yukon delta thu. There will
be patchy clouds and flurries with this. The main affect will be
north winds gusting to 25 mph with areas of blowing snow along the
trough. A second trough will move to the northern chukchi sea thu
pm and to the western arctic coast to bering strait by Fri am.

Will see more clouds and flurries with this feature... And north
winds gusting 25 mph with areas of blowing snow.

A series of short wave troughs will make their way north over
interior alaska over the next several days bringing snow or a
chance of snow with each feature along with periods of southerly
chinook winds near the alaska range.

The first trough moving north is now over the eastern brooks range
and will move north of the arctic coast this afternoon. Snow will
taper off to flurries as it moves north of the brooks range.

The second trough moving north is in the gulf of alaska and will
move north over the alaska range by 4am thu... To huslia to old
crow by 4pm thu... To ambler to barter island by 4am Fri and then
elongating northeastward. This trough will feed moisture north
over the interior causing periods of light snow. Snow will be more
focused along the surface frontal boundary that lies from denali
park to chandalar lake. Will address snow below with the surface
front. Snow will shut off just south of this trough as moderate
chinook flows develops thu. Will see south winds up to 40 mph
along the alaska range Thu into fri.

A third short wave moving north will move to the alaska range thu
night and over the interior fri. Expect downslope to prevent snow
in the eastern interior Fri but there should be some snow in the
western interior fri.

Surface...

a 1009 mb low just north of deadhorse will move to 100 nm north
of deadhorse as a 1010 mb low by 4pm wed... To 150 nm north of
deadhorse by 4am thu... Then dissipating. Flurries along this low
will move offshore with the low.

An occluded front stretching from denali to chandalar lake will
remain stationary through Thu am. A low over the kenai peninsula
will move to denali park as a 1008 mb low by 4am thu... And to
near bettles as a 1008 mb low by 4pm thu... And to just north of
barter island as a 1006 mb low by 4am fri. Snow along the front
will increase today as the surface low feeds moisture north along
the front. Expect 3-5 inches of snow along the front. Snow will
shut off south of the surface low on thu. Will see much lighter
amounts of snow with the low north of the brooks range.

Discussion
Models show similar solutions through Friday. See slight
differences in precipitation location but GFS showed locations of
snow best at 06z... So will use GFS locations. Start to see
differences in short wave features Fri night into the weekend.

Still agreement on the long wave pattern into next week. Will use
a more ensemble approach for this weekend into next week the long
wave trough remaining over western alaska with a ridge over the
nw canada and eastern alaska.

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.
