A weather front that is currently over the bering sea will bring
snow and gusty winds as it moves north and east across the
forecast area this evening into Monday.

Aloft, at 500 mb, a shortwave trough that is currently over the
bering sea will move north along the bering sea coast this evening
and along the chukchi sea coast early Sunday morning. A second,
stronger shortwave will push east across the bering sea on Sunday,
will reach the west coast of alaska Sunday evening and will push
east across the interior Sunday night and Monday. Westerly flow
will persist across most of the forecast area Monday night. On
Tuesday a high amplitude ridge will build over bering sea with the
corresponding deep trough situated over the yukon territory. The
ecmwf and the GFS both have the ridge axis slowly pushing to the
east through next weekend; however, they differ how far east the
ridge axis will move.

West coast and western interior: a front moving through the bering
sea will push through the west coast tonight. The front is
currently pushing over st. Lawrence island where blizzard
conditions are ongoing. The conditions on st. Lawrence island
will improve this evening; however deteriorating conditions are
expected on the mainland as the winds increase this evening and blowing
snow develops. The ongoing winter weather advisories for blowing
snow in zones 211, 212 and 214 look to be in good shape. In
addition, I added a few winter weather advisories for blowing
snow north of the bering strait (zones 207 and 209). The front
will push inland late tonight into Sunday. Relatively warm air
will lead to a mixed bag of precipitation, particularly for inland
areas south of galena. I added winter weather advisories of zones
215, 216 and 227 for a mixture of freezing rain and snow. For
inland areas of the western interior north of galena, snowfall
amounts tonight into early Sunday of 3 to 6 inches are expected.

North slope and brooks range: the front moving north along the
chukchi sea coast early Sunday will result in gusty easterly
winds developing. The increased winds combined with very cold
temperatures will result in wind chill values reaching advisory
criteria (minus 50 degrees fahrenheit in this case) along the
chukchi sea coast as well as portions of the beaufort sea coast
early Sunday morning. Thus, I issued wind chill advisories for
zones 201, 202 and 203. Areas along the chukchi sea coast will
see around an inch of snow as the front moves through. In the
brooks range, southerly gap winds with gusts to around 35 mph are
expected to develop early Sunday but should die down Sunday

Central and eastern interior: a front will push into the central
interior Sunday and stall. Snowfall is expected to develop along
the front. 2 to 4 inches of snow is expected early Sunday for
areas west of fairbanks. Freezing rain will likely mix with the
snow at times west of fairbanks. A shortwave trough will push
north and east into the central interior Sunday afternoon. This
will help to get the front moving again and will provide a surge
of moisture. From an additional 3 to 5 inches of snowfall is
expected across most of the central interior Sunday afternoon
through Monday afternoon. It is not out of the question
that some light freezing rain will fall in fairbanks Sunday
afternoon; however, right now this looks like it will be hit or
miss with a better chance of snow being the dominant precipitation
type. In fairbanks 3 to 5 inches inches of snow is expected
Sunday afternoon into Monday with the highest snowfall rates
expected to occur Monday morning right before rush hour. As far as
the winds go, southerly gap winds with gusts up to 45 mph are
expected to develop in the passes of the alaska range Sunday. On
Monday gusty westerly winds will develop across much of the
interior. The strongest winds will be just north of the alaska
range where gusts of around 40 mph are possible. In fairbanks wind
gusts around 20 mph are expected with higher gusts in the hills
north of town. The strong winds will be coincident with falling
snow and thus blowing snow will likely cause some travel
difficulties around the interior. A cooling trend is expected
after Monday as the upper level trough digs south over the yukon

Coastal hazard potential days 3 and 4... None.

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.
