Discussion
Models... The last few solutions have tracked well initially with
good run to run continuity in the first 24 hours. There continue
to be issues beyond the 24 hours. Good initialization of the
16 00z run against the 16 06z surface analysis. Will lean on the
nam for precipitation again today as it will be spotty around the
forecast area.

Aloft... At 500 hpa... Ridge over the eastern arctic coast will pull
back into canada by this evening. 505 dam low over nunivak island
will swing southeast as the trough opens up and moves east across
the state. By Sunday morning a 515 dam low will be over the
northern gulf of alaska, and a 512 dam low will be over the middle
tanana valley. The trough will continue to slowly move east to be
over the alcan border by Monday morning. Weak riding lies over the
dateline this morning and will move over the eastern bering sea
and chukchi sea by Sunday morning, and over the west coast by
Monday morning. It will continue east with the axis lying from
kodiak island to minchumina to wainwright Monday evening, then
over the alcan border by Tuesday afternoon. A 492 dam low will
move into the western bering sea by Sunday morning and to the
western gulf of anadyr by Tuesday morning at 490 dam. A strong
shortwave associated with the low will move to the eastern bering
sea by Monday afternoon, and over the west coast by Tuesday
morning. At 850 hpa... The forecast area is below zero, while
areas north of the brooks range are -10c or colder this morning.

A slow cooling trend will continue into Monday when a warming
trend will start on the west coast as a weather system moves into
the area.

Surface... High pressure remains over the arctic as it extends
southeast from a 1039 mb high near 80n 160e to south of banks
island and will persist into Monday before it is pushed just
offshore by the approaching low pressure system as troughing
develops over the arctic coast. A broad area of low pressure will
remain over most of the state as a stacked 973 mb low pressure
system that is over nunivak island this morning rotates southeast
to be over kodiak city by Sunday morning at 994 mb while a 984 mb
low develops over nenana this evening in leeside troughing, and a
997 mb low develops over kotzebue sound. A ridge of high pressure
over the central aleutians and central bering sea will move east
to lie from unalaska to st lawrence island by Sunday afternoon,
and over the southwest mainland and bristol bay by Monday morning.

A low pressure system will move to the western bering sea Sunday
morning with a front moving to the central bering sea and central
aleutians by Sunday night. The low will slowly move east in the
northern bering sea and the front will move to the west coast by
Monday afternoon. The front will bring some warmer air with it and
could produce freezing rain in the lower yukon delta and on st
lawrence island Monday.

Arctic coast and brooks range... Cloudy, light snow or flurries,
fog, blowing snow, and persistent winds of 20 to 30 mph will
continue through today and most of tonight. Winds will diminish a
bit Sunday to 10 to 20 mph, and the blowing snow will diminish as
the winds come down and the falling snow tapers off. Temperatures
will continue to cool.

West coast and western interior... A bit messy in the west as the
low has moved over nunivak island and snow is spreading north and
east. At least a period of snow for most locations today, with up
to 3 inches of accumulation. Winds diminishing this morning for
most of the area, but the stronger winds will hang on a bit longer
in the lower yukon delta, and around point hope. Temperatures
cooling through Monday morning. The next weather system will be
moving to the west coast and st lawrence island Monday and it will
be quite messy with models currently indicating snowfall of 3 to
10 inches, freezing rain in the lower yukon delta and on st
lawrence island, and winds gusting 50 to 60 mph on st lawrence
island and the bering strait coast. This is building into a
significant weather system that will impact the area that will be
monitored closely over the next couple days.

Central and eastern interior... Some light snow and flurries around
the interior will taper off as a decaying front moves to the
south slopes of the brooks range by this afternoon. Cloudy
conditions will prevail, but look for some breaks during the day.

Another chance of snow Sunday as a weak low moves east across the
area, but not looking for any significant snowfall today or
tomorrow. Temperatures will continue to cool. Gap winds in the
alaska range diminishing rapidly this morning, elsewhere winds
will be light.

Coastal hazard potential days 3 and 4... Strong south winds moving
to the west coast Monday may impact the area. There is some
potential for a minor ice push on the south facing coastal areas.

Extended forecast for days 4 to 7... A strong weather front will
move into the interior Tuesday and Wednesday that could produce 2
to 6 inches of snow.

Afg watches warnings advisories
Heavy freezing spray warning for pkz210-pkz220.

Gale warning for pkz210-pkz225.

Small craft advisory for pkz220.

Brisk wind advisory for pkz230-pkz235-pkz240-pkz245.

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.
