Synopsis
A series of storms will make their way up the west coast and the
north slope over the next few days, bringing strong winds and
heavy snow to those areas. Over the interior, a strong ridge of
high pressure will persist into next week, resulting in relatively
quiet weather and warmer temperatures through the weekend.

Aloft, at 500 mb, a strong ridge building in place over mainland
alaska is dominating the weather pattern over the interior. This
will bring quiet and generally clear conditions over the mainland,
and temperatures will gradually be warming into early next week.

The west coast and north slope are a different story, with
several shortwaves expected to impact those regions over the next
week. Currently, a shortwave trough moving northeast across the
chukchi sea and into the north slope has been the focus of
increased winds and snowfall across portions of the western coast
and the north slope. This feature will also serve to somewhat
dampen the ridge, and some snow may make its way farther inland
than a ridge this strong would normally allow. A second strong
shortwave trough is moving across the bering sea and will be the
next large system to impact western alaska over the next couple of
days. This second system will move up the west coast primarily
Saturday and Saturday night, and impact the north slope by Sunday.

Central and eastern interior: stratus clouds are rapidly clearing
out of the area under the intensifying ridge of high pressure. The
ridge will build north and strengthen Saturday and Sunday. Expect
one more night (tonight) of temperatures below zero across most
locations in the region, then gradually warming over the next
week.

West coast and western interior: a weather front associated with a
low moving ashore has brought widespread snow and strong winds to
the west coast.

At the surface, a 980 mb near CAPE navarin will move to 300 nm
north of point barrow as a 1002 mb by 3pm sat, and to near banks
island on sun. This will bring strong winds and heavy snow to the
western coast and the north slope through sat. This feature will
rotate through the ridge just offshore of the north slope, and
winds and snow will intensify in areas such as utqiagvik and
nuiqsut this evening and Saturday. Some freezing rain is possible
along the leading edge of this system as early
a second strong low will move north into the southern bering sea
fri night, to near CAPE navarin as a 980 mb low by 3pm sat, and to
wrangel island as a 979 mb low by 3pm sun.

Some freezing rain is possible along the leading edge of this
system as early as tonight and Saturday morning along the west
coast, moving into the north slope by Saturday afternoon and
lingering through Sunday. This storm will bring more strong winds
and heavy snow to the west coast through sat. While temperatures
may be warm enough along the coast to support freezing rain along
the leading edge Saturday and Sat night, and accumulations should
be very light. A trailing cold front will move into the west
coast sun, and then moves a little farther inland Sunday night.

This will bring more snow and winds to the west coast sun, and
also southerly winds will increase across the brooks range,
including the mountain passes, with gusts up to 45 or 50 mph.

Discussion
Gfs was model of choice through mon.

Coastal hazard potential days 3 and 4...

strong southerly gales will blow across the eastern bering sea
and the west coast of alaska now through Saturday night. Expect
sea levels to rise to 3 feet above normal in most areas this
weekend. This may cause water to seep into low lying areas along
the coast, such as along rivers and sloughs. At this time no
flooding is expected, but travelers should be aware of water
moving onto sea ice and river ice near the coast. The highest sea
levels should be Saturday night and early Sunday morning.

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.
