Synopsis
Snow will begin to fall across the north central brooks range
this afternoon and spread east as a low pressure system drops
south from the high arctic. A winter storm warning is in effect
beginning midnight tonight through Tuesday morning for heavy snow
totaling 4 to 8 inches in the eastern brooks range including the
dalton highway. A mix of rain and snow is expected along the
immediate arctic coast where temperatures will hover near or just
above freezing. Scattered showers are possible across the interior
late tonight into Monday as a low moves east through the gulf of
alaska. Snow is likely across higher elevations of the alaska
range Monday into Tuesday, including light accumulations on
denali park road passes. Most of the west coast will remain clear
of precipitation, through rain is likely across the y-k delta and
lower yukon south of galena this afternoon into early Monday.

Discussion
Aloft 500 mb...

a highly progressive longwave troughing pattern will continue to
encompass much of the eastern bering sea into western canada,
sending a series of shortwave systems east through the southern
portion of alaska. This pattern will be reinforced by a deepening
closed low over the arctic coast which will gradually drift into
the chukchi sea by Wednesday. This will force incoming bering sea
shortwave systems further south, allowing arctic air to infiltrate
farther and farther south into next weekend.

North slope and brooks range...

showers will increase along the coast through this evening as low
pressure drops south from the high arctic. Temperatures will
gradually fall, and a rain snow mix is expected to develop by
late this evening along much of the coast. In the brooks range,
northerly upslope flow along a developing frontal boundary will
amplify snowfall. The heaviest snow will fall along the front in
the north central brooks range from anaktuvuk and atigun pass, and
north to sagwon. 4 to 8 inches of snow is expected through Tuesday
and a winter storm warning is in effect beginning midnight tonight.

West coast and western interior...

rain will continue across the y-k delta and lower yukon through
early Monday morning, confined mainly south of nome to kaltag to
minchumina. Rainfall totals will amount to around a quarter inch
through that time. A few showers are expected farther north Monday
afternoon as a weather front sweeps southeast from the brooks
range. Otherwise, northerly winds will continue to gradually lower
temperatures throughout the week as an arctic low moves into the
chukchi sea by Wednesday.

Central and eastern interior...

partly cloudy skies are expected through tonight as a few showers
emerge north of the alaska range by early Monday. Much of
Monday's shower activity will be confined to the higher terrain
east of fairbanks to eagle. However, models are beginning to
depict greater chances for precipitation along a weather front
which will move southeast from the brooks range late Monday into
Tuesday. Freezing levels will begin to fall late Monday, and light
snow is expected across the higher terrain of the interior,
mainly north and east of fairbanks, as well as elevated passes
along the dalton highway. Rain and snow will mix at times Monday
night across parts of the northern interior such as bettles and
parts of the yukon flats. However, accumulation is unlikely at the
lower levels. The heaviest snow will be confined to the northern
brooks range. However, snow is likely in the southeastern brooks
range from the dalton highway as far east as arctic village,
with generally 1 to 2 inches of snow is expected through Tuesday.

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

Fire weather
Temperatures will continue a downward trend through late in the
week. Relative humidity values are expected to remain above 40
percent with excellent overnight recovery. Some gusty winds to 30
mph on summits above treeline Sunday evening into Monday morning.

Otherwise, winds generally north to east at 5 to 10 mph.

Hydrology
No areas of concern at this time.

Afg watches warnings advisories
Winter storm warning for akz206.

Small craft advisory for pkz210-pkz220-pkz225-pkz230-pkz240-

It is not checked for accuracy either by anyone at L-36.com 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.
