Synopsis
Aloft...

a ridge over northern alaska will weaken slowly through Wed then
strengthen slowly in the second half of the week. Temperatures
will remain above normal over the area south of the brooks range,
while the north slope will remain below normal through at least
mid-week. Interior alaska will see a general increase in clouds
through mid-week but remain generally dry while the west coast has
increasing chances of precipitation through mid-week.

A short wave trough in the gulf of alaska will move north over
the alaska range Mon night, to bethel to eagle by 4pm tue, and to
the bering strait to circle by 4pm wed. Will see moisture increase
ahead of this trough with a chance of precipitation along with
the trough. Will see weak downslope winds along the alaska range
following the trough tue.

A second short wave trough in the high arctic will move south
along the arctic coast of alaska Tue night and along the brooks
range wed. Expect this to continue feed of low level clouds,
flurries and fog into the north slope with clearing behind this
trough.

Surface...

a cold front stretching from 300 nm north of barter island to
barrow to CAPE lisburne will move to demarcation point to cape
lisburne by 4pm mon... Then along the brooks range by 4am Tue and
then persist into wed. A large area of stratus along with fog and
flurries is visible on satellite extending north to 80n. Expect
the stratus along with fog and flurries to push south over the
north slope with the front and persist into wed. Will see some
clearing Wed from the north with the trough aloft mentioned
above.

Patchy low fog currently along the arctic coast will thin by
afternoon as the stratus lay mentioned above moves over the
surface fog.

A 1028 mb high over the chukchi sea north of the front will build
southeast over the chukchi sea today and persist into wed. This
will cause north winds along the capes of the west coast and
through brooks range passes to persist through wed.

An arctic front stretching from savoonga to nome to indian
mountain to circle will persist through wed. Expect any
precipitation to fall as snow north of this front and mixed along
and south of the front... With mainly liquid further south of the
front.

A weak lee side trough over the tanana valley will persist
through tue. This will cause gap flow winds through alaska range
passes through tue... With some increase Tue as the trough aloft
passes north and enhances the lee side trough.

Discussion
Models initialize 10 to 20 dm too weak with heights in the high
aloft over northern alaska. Expect this to cause high aloft to
weaken slower than models indicate. Models agree on large scale
pattern of ridge weakening slowly through Wed then rebuilding
slowly through next weekend. The GFS again over does precipitation
in the eastern interior for the first several days. With weak
downslope flow through Tue the precipitation in the eastern
interior will remain nil today with just isolated showers from
tue into Wed along the arctic frontal boundary. GFS and ecmf
precipitation more similar over the west coast and a mix of them
seems reasonable.

Fire weather
Today will be slightly higher rh than sun... Then increasing
gradually through Wed as clouds increase. Highs will be in the 50s
south of the arctic front with lows in the 20s and 30s. Alaska
range passes will see gusts to 30 mph through tue. Could see
gusts spread north to delta junction on Tue with near red flag
conditions, but expect rh higher than 25% on Tue in the gusty
areas.

Afg watches/warnings/advisories
Small craft advisory for pkz210.

Brisk wind advisory for pkz220-pkz225.

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.
