Synopsis
A weather front causing rain now over fairbanks will move west
tonight and cause rain in the western interior tonight and fri.

A second weather front will move north from the gulf of alaska fri
and Fri night causing significant amounts of rain to spread north
over the eastern interior on Fri and Fri night.

On Saturday, a strong cold front will move east across the
eastern interior, causing snow levels to drop from 3500-5000 feet
fri night down to 2000 feet by Sat afternoon. This could cause
4-6 inches of snow above 3000 feet in the alaska range on sat,
with 1-2 inches possible across the eastern interior above 2000
feet on sat. Expect temperatures to fall during the day Sat and
for west winds to increase to 10 mph gusting to 20 mph.

Aloft...

the long wave pattern consists of a trough over the bering sea and
mainland alaska with a ridge over western canada. A series of
short wave troughs will move move northeast over mainland alaska
through this weekend bringing periods of rain snow. This will
keep NRN alaska in a cool wet pattern with periods of rain and
snow through early next week.

A low aloft just west of point hope will remain quasi-stationary
through sun. There is a surface low located under this feature.

The will cause scattered rain showers along the coast between the
bering strait and CAPE lisburne through Sat and possibly into sun.

A low aloft 200 nm north of deadhorse will move to near wrangel
island by 4pm fri, then merge with the first low on sat. This also
has a surface low located under this feature along with scattered
rain and snow showers.

A short wave trough along the west coast will move over the sw
interior tonight and to the central interior fri, then over the
eastern north slope Fri night and sat. This will induce a frontal
wave on the arctic front near illiamna tonight that then moves ne
on Fri into sat.

Surface...

a 997 mb low 80 nm west of point hope will remain quasi-
stationary through 4pm sat. This is cause scattered showers and sw
to NW winds over the southern chukchi sea that will continue
through sat.

A second 998 mb low 100 nm north of deadhorse will move to 100 nm
northwest of utqiagvik by 4am fri, and to near wrangel island by
4pm fri. Scattered rain snow showers will occur near this low.

This is causing SW winds and stratus fog along the arctic coast
now, with the winds turning east tonight then persisting along
with stratus and fog into Fri night.

A low pressure trough will develop over the north slope
of alaska Sat pm and persist into sun. This will cause rain snow
along the arctic coast Sat into sun.

A strong low moving into the northern gulf of alaska tonight will
move north over the eastern interior Fri and Fri night. This will
spread widespread rain northwest over the eastern interior fri
and Fri night. Could see .25-.50 inch of rain with this.

An arctic front that lies from old crow to denali to king salmon
will move to old crow to tanana to a 995 mb low developing near
illiamna by 4am fri, the move to arctic village to a 990 mb low
near ruby by 4pm fri, with a cold front from ruby to king salmon.

Rain along the front will diminish to a chance of rain tonight,
with rain likely south of mcgrath tonight, with rain moving north
along the frontal wave to the central interior on fri. By 4am sat
the front will be front arctic village to a 994 mb low near
bettles with a cold front from bettles to minchumina, and by 4pm
sat the low moving to chandalar lake as a 995 mb low with the cold
front from chandalar lake to tok, and then moving east of the
alcan border Sat evening. Rain occur along the front will occur as
snow at elevation. Snow level will remain 3500-4000 feet east of
the front through Fri night, with the snow level dropping to 2000
feet along the front on sat. Could get several inches of snow
above 2000 ft over the eastern interior sat, with 4-6 inches of
snow in the alaska range above 3000 feet. Also will see west winds
10g20 mph.

A 1004 mb low in the western bering sea will move to the central
bering sea as a 998 mb low by 4pm fri, to the yukon delta as a 993
mb low by 4pm sat, and over the seward peninsula as a 992 mb low
by 4pm sun. Expect rain to spread to the yukon delta and norton
sound with this low on Sat am, then move northeast to the seward
pen and SW interior on Sat pm, and to the area between the seward
pen and point hope by sun. Could see mixed rain snow with this sat
night and sun. Also expect winds 15-25 kt around the low center
fri into sat.

Discussion
Models initialize well aloft, and show similar solutions through
4pm fri. After that time, the NAM brings the short wave in the
bering sea into SW alaska more quickly than the GFS ecmf canadian
models. Since this feature will be dropping some of its energy
down the back side of the long wave trough on fri, favor the
slower GFS solution over NAM for Fri night into sun.

On precipitation, models similar through fri, then the NAM brings
in precip to the west coast more quickly with is faster surface
low. At this time, favor the GFS precip.

At the surface at 15z, models all verify 3 mb too weak on both the
surface low north of deadhorse and the surface low near point
hope. Following the pattern aloft, favor the GFS surface field to
account for the pattern aloft. Will account for the deeper surface
lows on the arctic coast by bumping up the winds around those two
surface lows by 3-5kt through fri.

Bottom line is we will use the GFS for precip, temps, winds
through Sun but bump up GFS winds along the arctic coast and nw
alaska by 3-5 kt through fri.

Coastal hazard potential days 3 and 4...

no significant issues expected.

Fire weather...

cool and very wet through the weekend. Rh will remain above 40%
through sat. Expect west winds 10g20 mph Sat across the eastern
interior accompanying a wet cold front.

Hydrology
Rises on interior rivers through weekend, with more significant
rises in the tanana river basin, but no flood issues expected.

Expect another .25-.50 inch of rain across most of of the eastern
and southern interior through sat, with up to 1 inch in the
alaska range.

Much of the alaska range precip will be snow above 3500 feet from
denali west, so should be less runoff in the denali area. From
isabell pass east, snow level remains 5000 ft through Sat morning,
then falls rapidly to 2000 ft during the day sat, so that area
will have more runoff and higher river values.

Afg watches warnings advisories
None.
