The models are in overall good agreement out through the middle
of the week. The main weather concern today will be the potential
for precipitation Monday in for the interior as well as the north
slope and brooks range.

Aloft, at 500 mb, a 531 dam low will persist over bristol bay
before starting to to move south Monday night. A shortwave
associated with this low will sit over the southeastern interior
tonight into Monday. A trough associated with a low in the high
arctic will move from west to east across northern alaska tomorrow
into Tuesday. While the models agree on the timing of this trough
moving across the state, they differ on how cold the air is aloft
the NAM has temperates a few degrees colder at 850 mb than the gfs
or the ecmwf, particularly in the northern portions of the
interior on Monday night. This will in turn have some impact on
snow levels Monday night in the northern interior. An upper level
ridge will build over the chukotsk peninsula on Monday and over
the west coast of alaska on Tuesday. A shortwave moving eastward
through the chukchi sea will help to knock this ridge southward
Tuesday night. The aforementioned shortwave will move across the
arctic coast on Wednesday. An upper level ridge will build along
the canadian border Wednesday into Thursday.

At the surface, a 998 mb low near bristol bay will persist
through Monday, gradually weakening. A cold front will move across
the arctic coast of alaska Monday into Tuesday. An area of high
pressure will build east just north of the brooks range Tuesday
behind the front. This area of high pressure will push east on
Tuesday night as a low pushes across the chukchi sea well north of
the coast. High pressure will build over the chukotsk peninsula
tonight, this will strengthen the pressure gradient over the
bering strait and northern bering sea for tonight and tomorrow.

Central and eastern interior: a front will move in to the interior
this evening and stall. The front is expected to stall along a
line from circle to fairbanks to mcgrath. Precipitation is
expected along this front from this evening through early Tuesday
morning with the heaviest precipitation expected early in the day
on Monday. An upper level trough associated with a low in the
high arctic will spread colder air aloft tomorrow and tomorrow
night. This will cause snow levels to drop between now and Tuesday
morning. Snow levels this evening across much of the interior will
be around 5000 feet and by Tuesday morning the snow level drop to
1000 to 2500 feet (higher from fairbanks south). Current thinking
is that the precipitation type will mainly be rain tonight and
Monday (with the main exception being above pass level in the
alaska range). On Monday night in areas above 2000 feet the
precipitation type will change to mix of rain and snow and by
early Tuesday morning to all snow. Fortunately the precipitation
will be tapering off by early Tuesday morning. Up to three inches
of snowfall is possible along the steese highway at eagle summit
Monday night. Conditions should clear up during the day on
Tuesday. Another round of precipitation will move from southeast
to northwest through the interior Wednesday night into Thursday.

West coast and western interior: some precipitation is expected
along a stalled front on Monday mainly for areas south of the
yukon river. High pressure should keep things relatively quiet
for Tuesday and Wednesday. There is some potential that a storm
system will affect the west coast over the weekend; however, at
this point, there is still a lot of uncertainty about the details
of this given the differences between the models.

Arctic coast and brooks range: a weather front will pass along the
arctic. As this front passes through it will bring snow. Generally
1 to 2 inches of snow is expected as the front moves through in
areas away from the coast. Lesser amounts are expected closer to
the coast where rain is expected to mix in with the snow.

Coastal hazard potential days 3 and 4... None. The models are
hinting at the potential for a storm affecting the west coast next
weekend; however, at this point, there is still a lot of
uncertainty about the details of this given the differences
between the models.

No issues anticipated at this time.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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 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.
