Discussion
Aloft...

a longwave trough continues to dominate over the west coast of
alaska from the chukchi sea and south into the northern pacific
ocean. High pressure is situated along the canadian border east
of fort yukon this morning. A weak cutoff low southeast of cordova
will move southeast today and be south of juneau by this
afternoon. High pressure will build into most of alaska behind
this low and remain in place throughout the weekend.

A second cutoff low northwest of wainwright will move east and be
north of kaktovik by early Saturday. Two merging longwave troughs
in the bering sea will persist in and around bristol bay into the
middle of next week. A series of shortwave troughs will come from
the south early next week and slowly break down the ridge.

Surface...

a thermal trough situated over chalkyitsik will track to the
northeast today. Scattered thunderstorms expected in this region
due to the favorable environment of 500-880 j kg CAPE and lifted
index between -1 and -2 this afternoon. A second low centered
north of wainwright will move east and merge with a developing low
north of kaktovik by this afternoon. As this low slides to the
east, high pressure builds into norton sound today.

The next feature of interest is a low tracking north from the
northern pacific ocean beginning this afternoon. The low will
continue to strengthen and be located northeast of atka by early
Sunday morning. Chinook gap winds expected to develop late
Saturday as the low continues to move north. Model consensus of
location and intensity still undetermined at this point, but
confidence is still high for a chinook event beginning Saturday
evening and lasting into early Monday morning.

North slope and brooks range...

snow currently falling at point lay and wainwright, with dense fog
from utqiagvik and east to deadhorse this morning. The surface
low pressure northwest of wainwright will track east today,
bringing isolated chances for rain and snow from point lay and
east to utqiagvik. Weak high pressure builds in along the north
slope Saturday afternoon, bringing partly to mostly cloudy skies
with intermittent fog and low ceilings along the north slope
through the weekend.

West coast and western interior...

dense fog occurring along the west coast and into kotzebue sound
this morning. High pressure builds into norton sound today, with
clearing skies throughout today and tonight. A strong low pressure
from the south will break down the high pressure in place over
norton sound beginning this evening. As this low continues to
track north, models are in good agreement with the next chance
for precipitation expected for the west coast and western interior
by Saturday evening.

Central and eastern interior...

a thermal trough is currently centered over chalkyitsik and
southeast to eagle. Scattered thunderstorms expected in the
eastern yukon flats today with frequent lightning, small hail, and
gusty winds. As the trough moves northeast and dissipates this
evening, thunderstorm chances in the interior diminish
significantly into early next week.

The approaching low into bristol bay this weekend will bring
southerly flow to the mountains. Chinook gap winds expected to
develop Saturday afternoon and last through Monday afternoon.

Maximum winds expected to be occur Sunday morning and into the
afternoon hours. Drier conditions in the interior expected
tomorrow as the chinook gap winds begin to develop tomorrow.

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

Fire weather
Thermal trough setup is centered around chalkyitsik and stretches
southeast to eagle today. This trough will allow for isolated
thunderstorms this afternoon from eagle to fort yukon. Scattered
thunderstorms expected from chalkyitsik and east to the canadian
border with frequent lightning, small hail, and gusty winds. The
thermal trough is expected to dissipate for the weekend, with only
isolated chances for thunderstorms around eagle on Saturday.

Winds up to 15 mph sustained from indian mountain to fort yukon
and north to the brooks range expected this afternoon, coincident with
the thermal trough and maximum daytime heating. Chinook winds
through the gaps will develop beginning Saturday afternoon and
reach its peak early Sunday morning. High confidence on gap flow
occuring but modest confidence on peak winds through isabel and
windy passes as model spread is still large on the low pressure
location and intensity in the eastern bering sea by early Sunday
morning.

Rh will remain above 30 percent today. A warming trend is expected
over the weekend, leading to lower minimum rh values for Saturday,
reaching below 25 percent in scattered locations in the central
and eastern interior. Sunday is forecasted to be the warmest day
in the interior for the near future. Minimum rh still hovering
around 25 percent in most areas of the interior for Sunday.

Hydrology
Flood warning for rapid snowmelt continues for the koyukuk river
at allakaket. Minor flooding of roads and outbuildings have been
observed as of 8 am yesterday. The river is expected to crest over
the weekend, with a slow retreat next week.

Flood advisory remains in effect for rapid snowmelt along the
koyukuk river downstream of allakaket to hughes. The river was
observed to be rising and overbank at one end of the airport
runway in hughes yesterday afternoon. High water and erosion
expected to occur as the high water crests at huslia towards the
middle of next week.

Afg watches warnings advisories
Brisk wind for pk240 and pk245.

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.
