Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK

.SYNOPSIS...
A strong southerly flow pattern for the next week will keep all
of Northern ALaska from the Brooks Range south much warmer than
normal for the next week. Chinook winds blowing across the Alaska
Range will keep the Eastern Interior mainly dry and 10-20F warmer
than normal, while the Western Interior will have periods of rain
and snow, the West Coast will have mainly snow and blowing snow,
and the Arctic Coast remains closer to normal temperatures. The
Brooks Range will develop Chinook winds Fri and remain warmer
than normal for most of the next week.
Aloft...
The long wave pattern consisting over a deep trough over the
Bering and NW Pacific with a ridge over Western Canada will
persist for the next week. A series of strong short wave will make
there way north over Alaska, bringing periods of strong chinook
winds to the INterior, and bring periods of snow and winds to the
West Coast, with a mix of rain and snow in the Western Interior.
Surface...
A 1004 mb low near Demarcation Point will move to near Inuvik as
a 1010 mb low by 4pm Fri and then move east. Strong winds and
blowing snow near Barter Island now will decrease tonight as this
low moves east.
A 993 mb low the Western Interior of Alaska will move to near
Kotzebue as a 998 mb low by 4am Fri, to near Cape Lisburne as a
1001 mb low by 4pm Fri, and then move north and weaken. A weather
front from this low to the eastern Brooks Range will move to
Kotzebue to Barter Island by 4am Fri, to Point Hope to north of
the Arctic Coast of Alaska during the day Fri, and then continue
north and diminish. This is bringing snow to the northern INterior
Now and will bring a chance of snow to the North Slope and NW Ak
tonight and Fri, This will keep east winds 25-35 kt and blowing
snow at POint Lay into Fri am.
A 987 mb low 150 NM southwest of Gambell will weaken very slowly
in place through Sat. An arctic cold front stretching from this
low to the Yukon Delta will move to Nome to Shageluk by 4am Fri,
to Point Hope to Mcgrath by 4pm Fri, to Wainwright to Ambler to
Anvik by 4am Sat, and then moving back over the West Coast Sat.
Snow along this front will spread inland with the front with 1-2
inches along the West Coast and Western Interior through Fri.
A strong low developing in the Gulf of Alaska on Fri will move to
near King Salmon as a 984 mb low by 4pm Sat and then to near the
Seward Pen on Sun. This will push moisture north along the Arctic
front causing snow to become a bit heavier Sat and Sun.
Could see 4 inches or more along the Nulato Hill to the Western
Brooks Range Sat-Sun. Warm air with this low will bring a mix of
rain and snow to the Western and Northern Interior Sat and Sun,
while the SE Interior remains dry.
Strong southerly chinook winds blowing across the Alaska Range
will taper off late tonight and then resume again Fri Night into
Sat. These winds will blow off and on for much of the next week.
This will keep temperatures 10 to 20 degrees above normal over
the Eastern Interior for the next week.
Most areas south of the Yukon River will reach into the 30s and
even the 40s during the day time for the next week, while low
temperatures will be in the teens and 20s. A few calm valleys will
see lows near zero.

.DISCUSSION...
Models initialize well aloft and show similar solutions through
4am Sun. After that time, the GFS and and ECMF and faster than the
NAM and Canadian at moving a strong short wave north across the
Gulf of AK and into S Central AK on Sun PM. Favor the faster GFS
solution, as this very dynamics southerly flow aloft is a set up
to move features quickly and cause rapid deepening.
The GFS and ECMF precipitation fields are broader in area of
coverage than the NAM. Favor the broader GFS areal coverage due
to the slight uncertainty in timing, and the generally southerly
wet flow.
At the surface, models verified well on most features at 15Z, excepting
the high north of the Arctic Coast which was stronger than models
indicated. This will result in slightly stronger winds overt he
Arctic Coast through tonight than models indicate.
Mid range Tue-Fri looks like models are in agreement on the long
wave pattern consisting of a high amplitude trough over the Bering
and NW Pacific and Ridge over NW Canada. Models show little to no
agreement in timing of short wave features, so may need to use
ensemble approach for timing, but will likely need to adjust
surface low depth to max depth shown by deterministic runs.
Bottom line for Northern AK, is this looks like a return to the
very wet, warm and windy pattern of last week for Northern Alaska,
but with little agreement on timing of individual storms.
Coastal Hazard Potential Days 3 and 4...None.

...Very Warm In the Interior for the Next Week...
There will be strong southerly chinook winds blowing across the
Alaska Range off and on for much of the next week. This will keep
temperatures 10 to 20 degrees above normal over the Eastern
Interior for the next week.
Most areas south of the Yukon River will reach into the 30s and
even the 40s during the day time for the next week, while low
temperatures will be in the teens and 20s. A few calm valleys will
see lows near zero.
