northern alaska forecast discussion
national weather service fairbanks ak
519 am akdt Thu may 25 2017

Discussion
The active pattern across northern alaska
continues. The main forecast challenge today will be a low
pressure system currently over northwestern alaska that will bring
precipitation to a good portion of the forecast area today. The
models are in good agreement out through the weekend.

Aloft, at 500 hpa a 522 dam low currently situated just north of
the bering sea will move to just north of the bering strait today
where it will be quasi-stationary through late Friday. The upper
low center will push off to the north on Saturday; however, an
upper level trough will remain over the western half of the state.

An upper level ridge will begin pushing into the interior on
Sunday. This ridge will spread west and strengthen early next
week resulting in warmer air aloft moving into the area; however,
by this point there are differences in the models on exactly how
this will play out.

At the surface, a 996 mb low 125 nm NW of kotzebue will slowly
drift northwest and weaken through Friday evening. A 999 mb low
will develop just south of deadhorse this afternoon. This low
will move to 100 nm N of barrow by early Friday morning and will
continue to push nw. A 1002 mb low will develop today in the gulf
of anadyr and will move over st. Lawrence island early Friday
morning before dissipating. A very tight surface pressure gradient
over eastern alaska range will gradually decrease today.

North slope: a weather front moving through will move across the
north slope today will bringing precipitation along with it.

Model sounding show that before the front passes through there is
the potential for freezing rain across most of the north slope.

The area where the potential is the highest is in zone 202,
particularly in barrow where the highest QPF values are expected.

A freezing rain advisory has been put out for zones 201, 202 and
203 through the afternoon. As the front passes temperatures aloft
will cool resulting in any precipitation changing over to snow.

There will be some scattered showers east of barrow; however no
significant. We do expect less fog in coastal areas east of barrow
this afternoon and all along the coast tomorrow as the wind
direction becomes southerly.

Central and eastern interior: a weather front will continue to
pass through the interior this morning. This will result in
temperatures today in most ares being cooler than yesterday. A
winter weather advisory remains in effect for portions of denali
np (particularly from polychrome pass west) where another 5 to 10
inches of snow is possible through Friday morning. Elsewhere
scattered to numerous rain showers today with the best highest
precipitation amounts south and west of fairbanks as a shortwave
rotates around an upper low in northwest alaska. The snow levels
will drop tonight. This will result in mixing with or changing to
snow at lower elevations. In most locations the snow will melt as
soon as it hits the ground. Some locations above 2000 feet could
see an accumulation of a few inches; however, accumulating snow
snow will not be widespread aside from locations in the brooks or
alaska ranges. Many locations close to the southern slopes of the
brooks range could see 2 to 5 inches of snow through Friday
morning. An inch or two is possible above 2000 feet along the
parks and richardson highways through the alaska range. Looking
forward, a warming trend currently expected Sunday into early next
week.

West coast and western interior: the wet pattern will continue
today across the west coast and the western interior. Scattered to
numerous rain and snow showers are expected. Snow accumulations
will generally be less than two inches at the most, with most
locations receiving less. The showery pattern looks to continue
through the weekend with some improvement early next week.

Fire weather
The cool and wet pattern will persist today across northern
alaska. Most locations will see minimum relative humidity values
well above 30 percent. A slow drying trend will begin tomorrow.

Hydrology
Rivers and streams in the interior are starting to
go down after the last rain, and with more on the way expect them
to start rising a bit on Friday, but do not see any issues at this
time. Current forecasts keep them below any action stages. No
updates on the arctic river situation as breakup continues its
slow steady march.

Afg watches warnings advisories
Freezing rain advisory for akz201-akz202-akz203.

Winter weather advisory for akz225.

Brisk wind advisory for 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.
