.SYNOPSIS...
A cold front continues to push SE from the Chukchi. Ahead of the
front, today, a chance for thunderstorms is possible along a line
from the Yukon Flats to the Upper Kuskokwim as instability
increases. In addition, gusty winds can be expected across the
Interior today. The associated upper-level, Arctic trough will
continue to dig south through the start of the week. This will
bring a brief period of seasonably colder temperatures to much of
the state. Thunderstorm chances shift further SE on Monday as the
front moves across the Interior, however widespread showers can be
expected during the day. As the week continues, a gradual warming
trend can be expected.

.KEY WEATHER MESSAGES...

Central and Eastern Interior...
- Gradually cooling temperatures are expected through the weekend
  into early next week as increasingly scattered showers and
  isolated thunderstorm chances build in across the Interior.

- Scattered showers and isolated thunderstorms will be along a
  line from the Upper Kuskokwim to the Yukon Flats, today, ahead
  of the cold front pushing SE.

- Gusty west/southwest winds will increase across the Interior
  today, strongest farther north and across higher elevations
  where gusts up to around 30-40 mph are expected.

- Dependent on clearing skies, low temperatures Monday night and
  Tuesday night will bottom out in the 30s and 40s for most, with
  coldest valleys dropping to around freezing. We will continue to
  monitor the potential for frost/freeze headlines for Fairbanks
  during this timeframe.

- More widespread showers expected across the Interior on Monday
  with the frontal passage. Showers will become more isolated
  starting Tuesday, with warmer and drier conditions building back
  across the Interior Wednesday onwards as daily isolated showers
  persist.

West Coast and Western Interior...
- Dry conditions will continue across Western Alaska through
  tonight, with highs cooler on the coast in the 30s/40s/50s and
  warmer inland in the 50s/60s/70s.

- A cold front building in out of the northwest today will
  support scattered rain and snow showers as a colder airmass
  builds in. Showers will shift inland and towards the Y-K Delta
  later in the day Sunday into Monday. Light snow accumulations
  will remain confined to the Northern Seward Peninsula and NW
  Arctic Coast.

- Colder and drier conditions on Tuesday will give way to a
  warming trend Wednesday onwards as temperatures return to more
  seasonable levels with highs rebounding into the 50s/60s/70s
  regionwide.

North Slope and Brooks Range..
- Widespread light snow is expected across the Arctic
  Coast/Plains, with heavier totals in the Brooks Range. A Winter
  Weather Advisory is now in effect tonight through Monday for the
  Central Brooks Range for snow accumulations of 5-10 inches and
  wind gusts up to 30 mph.

- Below normal temperatures continue today north of the Brooks
  Range with highs/lows in the 20s/30s while warmer air remains
  situated to the south of and in the Brooks Range where highs in
  the 40s/50s/60s and lows in the 30s/40s continue.

- Isolated to scattered rain/snow showers will continue to build
  in out of the northwest across the North Slope, expanding to the
  Brooks Range Sunday into Monday as a cold front passes over the
  region.

- Behind the Sunday/Monday cold front, isolated to scattered snow
  showers will continue for Tuesday ahead of warmer and drier
  conditions returning Wednesday onwards as highs build back into
  the 50s/60s/70s with 30s/40s along the coast.

.FORECAST ANALYSIS AND DISCUSSION...
Broad southwesterly flow continues across much of the state with
the 505 decameter low in the Arctic. A weaker low, around 535
decameters, continues to move westerly across Gulf toward the
Alaska Panhandle. Attention pivots toward a cold front, in
association with the Arctic low, that will push SE from the
Chukchi over the next couple of days. Today, areas out ahead of
the front, specifically along a line from the Yukon Flats to the
Upper Kuskokwim, will see the potential for thunderstorm formation
as steeper lapse rates move in. This trough will also tighten
heights, aloft, which will allow the potential for gusty winds
from the West Coast to the Central Interior today. Daytime heating
will also be more sufficient out ahead of the front which will
further support thunderstorm chances. Model soundings along the
line from the Upper Kuskokwim to the Yukon Flats show adequate
amounts of speed sheer which may promote chances for small hail
growth. In addition, sounds are also showing deep inverted `V`
shape from the surface to around 5000 ft. This suggests that some
of these storms have the potential to produce gusty down bursts.

The upper-level trough will continue to dig south, pushing the
front farther SE on Monday. This will allow for thunderstorm
potential along the Eastern Interior and Upper Tanana as the front
will not have passed over just yet. Rain will be the main precip
type for most of the Interior. Areas over the Brooks Range will
see mostly snow with the cooler temperatures still in place. In
addition, this setup will provide widespread snowfall across the
Brooks Range throughout the day today into the early hours on
Monday. A Winter Weather advisory remains in effect for the
Central Brooks Range. Total snowfall accumulations are expected to
be between 5 and 10 inches. The gusty winds, mentioned earlier,
mixed with the snow could produce areas of blowing snow at times
as well.

A more widespread swath of precipitation is expected under the
front itself, bringing another round of showers across the
Interior on Monday. Colder temperatures will accompany the front
as it works its way south, with lows regionwide in the
20s/30s/40s. We will continue to monitor the potential for
frost/freeze headlines for Fairbanks during this timeframe, which
will be centered around Monday night and Tuesday night when
temperatures are expected to be coldest. This will be followed by
a gradual warmup through the rest of the week. More on this in the
extended portion of the AFD.

.FIRE WEATHER...
Sunday, a band of vorticity being stretched from from the middle
Kuskokwim Valley to the Yukon Flats will help showers and isolated
thunderstorms develop over that area, with the highest likelihood in
the Eastern Interior. After Sunday, thunderstorm coverage is pushed
back into the Southeast corner of the Interior as a cold and dry air
mass digs down over Northern Alaska through the middle of the week.

Speaking of the arctic air mass, it is presently keeping the
Northwest parts of Alaska cool, highs under 60F with lows below
freezing. The cold temperatures will suppress fire activity for the
near future and a cold front will begin to swing southeast across
the state on Monday. As it does, it will bring widespread, light
showers through the day Monday. Behind the front temperatures will
be cool but also dry with minimum relative humidities in Interior
Valleys bottoming out in the 20s after the showers end on
Tuesday.

.HYDROLOGY...

No changes from the previous hydro forecast discussion.

Sagavanirktok, Colville, and Kuparuk Rivers

Below normal temperatures continue across the North Slope, with
APRFC`s breakup map continuing to show some open to mostly open
water on the Sag, Colville, and Kuparuk Rivers outside of
immediately along the Arctic Coast where mostly ice remains in
place. Colder temperatures will remain in place through early next
week with warming temperatures expected Tuesday onwards. By as soon
as Thursday and Friday, highs in the 50s and 60s will be in place
across the Arctic Plains with 30s/40s along the Arctic Coast. This
will likely accelerate snowmelt and lead to rises on North Slope
rivers. With the recent cooldown and drop overall in most river
levels, this will likely give enough room for new snowmelt to join
the channels and help mitigate any significant flooding concerns at
this time.

.EXTENDED FORECAST DAYS 4-7...
On Wednesday, the big upper low over the Arctic will loosen its grip
as a ridge over Canada and the Aleutians begins to merge. This
brings a warm up to most of Northern Alaska through next weekend.
While ridging usually means warm and dry, this will be a bit of a
dirty ridge since there is a remnant low in the Gulf. This means
there`ll likely be clouds around with showers and storms across the
region. Exact details with the placement of showers and storms are
uncertain as numerous shortwaves meander around Northern Alaska.
Then towards the weekend, there is a bit more uncertainty with what
happens with the ridge over Canada. However, compared to yesterday,
there is more consensus that the ridge will set up along or just to
the west of the CONUS west coast late next week and into the
weekend. This leaves room for a low around the Alaska Peninsula or
western Gulf of Alaska which would continue to provide southerly
flow to much of Northern Alaska. What all of this is saying is, a
return of summer-like weather is expected in the extended period
with more widespread showers, thunderstorms and warmer temperatures.
Speaking of temperatures, there may be a prolonged period of mid 60s
to mid 70s, potentially warmer, in the Interior with 50s/60s along
the West Coast and 40s to 60s from the North Slope to the Brooks
Range.
