Discussion
Synopsis...

aside from a few trouble spots across the west coast and north
slope, relatively benign weather is expected over the next couple
of days. High pressure will keep conditions mild across the
interior as a weather front along the west coast moves offshore.

Snow, wind and low visibility will be the primary threat through
Friday for areas along the western seward peninsula and yukon
delta. The north slope will see winds begin to increase Friday as
high pressure builds to the north. Very strong winds and blowing
snow are likely to reduce visibility through early Saturday.

Aloft 500 mb...

a high amplitude longwave pattern across the north american west
coast continues to be anchored by a deep low in the north pacific
and a strong high over the great plains. The longwave trough
engulfs much of eastern siberia, the bering sea, and the gulf of
alaska, though a weak high pressure system does exist over the
northern kamchatka peninsula. Over the weekend, the north pacific
low will begin to separate from the longwave trough as it becomes
cutoff. This will allow high pressure to strengthen over the
central bering sea and for the pattern to become more progressive
in this region. By Saturday a low will develop over the
southwestern bering sea and and rapidly deepen as it tracks east.

This system will facilitate a return to mild temperatures and
messy wintery precipitation across the west coast and even the
north slope Sunday into Monday.

North slope and brooks range...

a stalled frontal boundary over the eastern brooks range and
beaufort coast will provide light snow into this afternoon. As
high pressure continues to build east across the arctic sea, the
front will fall apart, though east winds will increase as the
pressure gradient tightens. By Friday morning, loose snow
accumulated over the last few days will begin to blow, causing a
drop in visibility to one quarter mile or less for most areas of
the north slope from CAPE lisburne to wainwright as well as from
nuiqsut to barter island. Winds across these areas could gust to
45 mph or greater at times and blizzard warnings have been issued
accordingly. The lone exception will be near utqiagvik, where
lower accumulated snow totals and slightly weaker winds will cause
a less drastic visibility reduction. A winter weather advisory is
in effect for this area. Activity in the bering sea this weekend
will facilitate a major pattern shift early next week as an
invasion of significantly warmer air from the southwest seems
imminent.

West coast and western interior...

a well-defined warm front associated with north pacific low
pressure will move into the y-k delta from the southeast this
evening. This front will catch up to and overtake the occluded
boundary slowly weakening over the western bering sea. Warmer
temperatures will cause a wintery mix of precipitation to occur
into Friday for areas mainly south of the bering strait,
including the southern seward peninsula, eastern norton sound and
y-k delta. Precipitation will be mainly light, though cooler
temperatures farther west will mean an all-snow event for st.

Lawrence island and diomede into late Friday. The next major
system is expected to develop in the western bering this weekend
and track eastward towards the coast. The leading front associated
with this low will reach the coast early Sunday, causing a
southerly reversal of prevailing flow and facilitation a messy mix
of rain and mixed freezing precipitation across much of the west
coast and western interior into Monday.

Central and eastern interior...

abnormal warmth is expected to continue across the region as a
stubborn high pressure ridge refuses to budge. Large scale
southerly flow continues to produce intermittent chinook
conditions resulting in a further increase in temperatures. The
next round of strong gap winds is expected late Saturday as yet
another front rotates up and over the alaska range. East winds are
expected to increase across the brooks range Friday, reaching 30
mph over dalton highway summits. However, visibility should remain
stable, as warmer temperatures should prohibit any significant
blowing snow.

Models...

as usual, models initialize 2 to 3 mb too high along the beaufort
coast, though no major issues elsewhere. Synoptically, good
concensus exists through early next week, including the upcoming
pattern shift expected in the bering sea, with only slight
deviations on shortwave features.

Coastal hazard potential days 3 and 4... Back-to back bering sea
lows will begin to impact the west coast Sunday and continue
through next week. Models are beginning to display better
consensus on timing and strength of the event. However, thin ice
cover across much of the area, particularly in the norton sound,
will complicate the forecast in terms of impacts to local
communities. Surge models indicate a rise in sea levels beginning
early Sunday, though offshore winds prior to the event should
mitigate any significant rise. Regardless, strong southerly flow
is expected to cause elevated surf, mainly along south-facing
shores. We will continue to monitor for additional developments.

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.
