Discussion
High pressure will continue to bring warm and dry weather to much
of northern alaska. Isolated thunderstorms from the north slope
south to the interior will persist into Friday and continue over
the interior through the weekend. Today is expected to be the
warmest day so far this year with temperatures in the 70's and
80's over a wide swath of the forecast area. Temperatures will
also climb into the lower 60's along portions of the arctic coast
as stratus and fog get pushed offshore. Slightly warmer
temperatures are expected in the central and eastern interior on
Friday.

High pressure aloft will remain over the interior but weaken some
through the weekend. Low pressure aloft over the yk-delta will
gradually drift offshore and remain nearly stationary over the
bering sea. A sharp trough will drop out of the high arctic and
into the northwest arctic coast late Friday. This will bring
cooler temperatures to western and arctic alaska and push the main
core of warm air east to the alcan border. Models are in good
agreement the next 48 hours and we will only make very slight
adjustments to the current forecasts.

Arctic coast and brooks range... A nice warm and sunny day over
the arctic as fog has pushed offshore. Fog will likely move back
to the coast east of utqiagvik tonight and impact deadhorse to
barter island before burning off again on Friday. Temperatures
will cool starting Friday. Winds will shift to the north and
northeast on Saturday and increase to 10 to 20 kt across much of the
region.

West coast and western interior... Isolated showers and thunderstorms
will develop from the brooks range south across the western
interior and into the seward peninsula this afternoon and evening.

Thunderstorm activity will diminish the next couple days and
mainly be east and south of galena by Saturday. Winds will be
variable inland and mainly 15 kt or less over the marine waters.

Temperatures will cool into the 60's and lower 70's by the
weekend.

Central and eastern interior... Hot and dry weather will continue
into Friday with a slight cooling over the weekend. Friday will be
the warmest day with readings approaching 90f in the yukon flats.

Isolated thunderstorms will be west of a line from bettles to
northway today. Thunderstorm activity will slowly shift east the
next few days and develop as far east as the alcan border by
Sunday. A tightening pressure gradient over the northeast interior
on Saturday will bring increasing northerly winds, especially
through brooks range passes.

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

Fire weather Hot and dry especially over the eastern interior
with temperatures well in the 80's and relative humidities in the
20's percent range. Cooler temperatures in the west with relative
humidities in the 30 to 40 percent range the next few days. As
mentioned above, thunderstorm activity will shift east through the
weekend. Other than thunderstorm gusts, variable winds 10 mph or
less. Northeast winds will increase to 10 to 20 mph over the
south slopes of the brooks range late Saturday and we will keep an
eye on whether conditions may approach red flag criteria.

Hydrology Warmer and drier with melting level above 9000
feet the next couple days. High elevation snow and glacier melt
will bring increasing flow to the streams fed by them, and
mainstem rivers like the tanana will slowly rise over the next few
days.

Afg watches warnings advisories
None.

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.
