Discussion
Models... Still seeing the same trend with models trying to bring
far too much precipitation into the interior. NAM seems to have
the best handle on it again today so will lean that direction. Big
picture the models are in good agreement into the midrange. For
the 26/00z runs the surface initialized well at 26/06z against the
in house analysis.

Aloft... At 500 hpa... Ridging persists over the interior extending
from whitehorse yt to a 534 dam center over wrangel island. A 548
dam low nearing banks island has a shortwave extending southwest
over the eastern arctic coast into the arctic plain and it will
drag east exiting the area Thursday morning. A shortwave
associated with a low over the western aleutians will move north
into the central interior tonight breaking down the ridging a bit
and pulling some moisture north. The 524 dam low over the western
aleutians will move east and dissipate over sand point Friday. The
534 dam high over the chukchi sea will slowly move east to be
over point barrow by Thursday afternoon at 536 dam, then merges
with the ridge as it moves over the beaufort sea Friday. The low
over unalaska yesterday continues to move east and will move into
northern british columbia and dissipate Saturday night. A 517 dam
low in the sea of ohkotsk Thursday will move east to be over
shemya by Saturday evening. At 850 hpa... Temperatures a bit cooler
as they fall another 3 to 4 degrees celsius over the next couple
days across the forecast area before starting to warm again.

Surface... A 1021 mb high over the central arctic will continue to
move east with ridging persisting east to west across the area.

Weak troughing persists over mainland alaska and the bering sea. A
1005 mb low develops in the upper tanana valley Thursday but at
this time looks like little impact. Troughing persists over the
west coast as a series of lows moves into the the central
aleutians and dissipates only to be replaced by another low. Some
gap winds in the brooks range is the gradient tightens over the
area with the high moving east. Gradient also tightens a bit in
the upper yukon river valley and winds may be gusty around eagle
later today and tonight.

Arctic coast and brooks range... Stratus and flurries over the
coast and plains will continue. Sheet of stratus looks like it
covers most of the arctic and extends well west into the siberian
arctic. No significant snow accumulations. Patchy fog. Winds
northeast to east 10 to 30 mph with the strongest winds over the
northwest coast.

West coast and western interior... Pretty similar to yesterday with
lots of clouds and some showers of rain and snow mainly south of
the bering strait. Mainly rain, but mixing or changing to snow
overnight north of the lower yukon delta. Strong winds out on st
lawrence island and in the bering strait with gusts around 40
mph. Otherwise winds winds northeast to east at 5 to 20 mph on
the coast, and 5 to 10 mph in inland areas.

Central and eastern interior... Generally cloudy, but sunshine
breaking through at times. Some showers moving through the area
tonight into Thursday afternoon will bring a chance of measurable
rainfall, mainly east of tanana and south of the yukon river.

Winds northeast to southeast at 5 to 15 mph.

Fire weather Cloudy, with some periods of sun, with relative
humidity values falling near 30 percent in a few upper tanana
valley locations for a short time this afternoon. Showers tonight
bring a chance of wetting rains to the eastern alaska range and
areas south of delta junction. Showers will move through the
central and eastern interior Thursday, but not expecting
significant accumulations. No significant winds expected through
the weekend.

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.
