Discussion
Current overview...

mostly cloudy conditions currently across most of alaska, except
along the west coast where skies are clearing out from point hope
south to unalakleet. A weak low pressure currently centered in
norton sound continues to move south, resulting in strong
northeast winds along the west coast, north of unalakleet. Light
snow along with onshore flow on the north slope from wainwright
east to kaktovik expected to continue for Thursday. Isolated to
scattered snow showers in the eastern interior expected to
increase in coverage throughout today.

Aloft...

at 500 mb, a 510 dam low is currently centered over st. Micheals
with weak ridging in the interior. Over the next 24 hours,
troughing over the west coast and western interior along with weak
ridging in the interior will continue. A 513 dam low will move
southwest from the beaufort sea to point lay, with the 510 dam low
over st. Micheals moves south to togiak. The low over togiak will
bring a shortwave northward on Friday, moving over the alaska
range and into the interior early Saturday morning. Beyond 72
hours, model guidance of a longwave trough over western alaska
continues, but details of low placement and intensity are unclear.

Surface...

the weak surface low currently over norton sound will continue to
move south and weaken throughout today. A high pressure extending
north of 80n in the arctic sea will remain quasistationary and
persist into the weekend. A second low pressure situated in the
gulf of alaska will move into yakutat by this afternoon and
continue moving north into the eastern interior by Friday
morning.

North slope and brooks range...

a weather front continues to push through the eastern north slope
today, bringing light snow with accumulations up to an inch from
nuiqsut to kaktovik. Northeast winds of 10 to 20 mph will
continue throughout the rest of the week and into the weekend.

Areas of low stratus, fog, and flurries will continue with the
northeast winds.

West coast and western interior...

strong northeast winds from point hope south through the bering
strait and to st. Lawrence island will begin to subside this
morning. Winter weather advisories for zones 213 and 217 are
active for the wind gusts and blowing snow. The weak low pressure
located in norton sound will bring scattered snow with light snow
accumulations south of norton sound today.

Central and eastern interior...

a weather front moving through the interior will bring numerous
snow showers for today. Snow accumulation ranging from 1 to 4
inches are possible from eagle west to the dalton highway and
surrounding hills north of livengood. Fairbanks snow accumulation
expected to be up to 1 inch. As the flow turns more southerly
after today, chinook conditions will decrease chances for more
snow on Friday and into Saturday for fairbanks. The best chances
for snow stretch from tanana northeast to arctic village for
tomorrow night and into Saturday.

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

Fire weather
Dewpoints along the tanana river valley east of delta junction
have began to rebound, as the low pressure south of the alaska
range continues to move north, increasing minimum rh values above
30 percent into the weekend. Weak downsloping will develop early
Saturday morning, decreasing rh values below 25 percent with peak
gap flow winds of 25 to 35 mph.

Afg watches warnings advisories
Winter weather advisory for ak213-ak217.

Heavy freezing spray warning for pkz200-pkz210-pkz215.

Brisk wind advisory for pkz220-pkz225.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
