.KEY WEATHER MESSAGES...
Central and Eastern Interior...

- Much colder temperatures will move into the area through the
  weekend as snow levels slowly drop to 2000 feet by Sunday.

- Frost possible in valleys Monday morning where skies clear.

- Rain and snow or all snow possible above 2000 feet elevation by
  Sunday. Accumulating snow possible at Coldfoot, over summits,
  and through Alaska Range passes. See Special Weather Statement
  for details.

- Breezy easterly winds Saturday turn westerly overnight into
  Sunday.

- Due to very cold temperatures aloft, isolated thunderstorms are
  still expected across the eastern Interior, mainly over terrain
  on Saturday.

West Coast and Western Interior...

- Clearing skies across the West Coast with conditions remaining
  mostly clear through the weekend. Areas of fog possible in the
  mornings along north facing shores.

- North-northwest marine winds 15 to 25 mph shift westerly Sunday
  morning and southerly Sunday night. Southerly winds strengthen
  through the Bering Strait Monday to 25 to 35 mph.

- Temperatures will be well below normal with highs mainly in the
  40s. Frost is likely across Western Interior valleys in the
  mornings where skies are clear. Warming back to seasonable
  conditions expected beginning Monday.

North Slope and Brooks Range..

- Heavier snow showers persist in the Brooks Range and north to
  Toolik Lake through Sunday evening. Lighter showers expected to
  continue through Monday. Additional snow accumulations of 3 to 6
  inches possible.

- Intermittent snow showers are also expected across the North
  Slope and Arctic Coast east of Deadhorse through Sunday.

- Well below normal temperatures continue with highs around
  freezing and lows mainly in the low 20s. Warming is expected
  toward the middle to end of next week.

- Persistent onshore flow results in low stratus and fog potential
  continuing through the weekend, especially during the `night`
  when the sun is lower in the sky.

- Winds generally 20 mph or less.

.FORECAST ANALYSIS AND DISCUSSION...
A trough stretches from the Arctic through a 530 dam upper level
low over the Western Brooks Range to a stacked 530 dam low just
southeast of Kodiak Island in the Gulf of Alaska. A 990 mb
surface low sits under the stacked low. The northern of the two
upper level lows is very cold for this time of year with 850 mb
temperatures near -10C. The southern low is sending ample moisture
over the Interior as a front passes through Saturday afternoon
creating ample opportunity for showers through Monday. With the
colder temperatures, snow is very likely in the Brooks Range and
Alaska Range with these systems and quite possible along Interior
summits, especially in the early morning when surface temperatures
are coolest. Cold rains are expected for Interior Valleys.
Easterly surface winds peak Saturday evening in the Eastern
Interior as the front passes by and then shift westerly Sunday.

A ridging pattern moves into the Bering Sea by Sunday and pushes
into the North Slope and West Coast by Monday afternoon. The Gulf
of Alaska low slows its progress in the Interior as it fills in,
but not for long as the ridge builds further into the Interior by
Tuesday night. Temperatures across the region see a warming trend
under the ridge and climb back to seasonal normals by midweek and
above normal for the weekend.

&&

.FIRE WEATHER...
Isolated thunderstorms possible along elevated terrain in the
Eastern Interior from the southeast slopes of the Brooks Range to
the Fortymile Country Saturday afternoon. A front moves north into
the Interior Saturday afternoon bringing numerous showers to the
area through Monday. These showers will be quite wet with high
chances of wetting rain, especially along elevated areas. Cool
temperatures persist through Monday which will keep fire weather
concerns to a minimum. Ridging begins to build in Tuesday through
the end of the week which will bring a warming and drying trend to
the area, before another low approaches the West Coast near the
end of the week to push the ridge out again.

&&

.HYDROLOGY...
The only breakup concern remaining is the Sag River. Temperatures
remain below normal through early next week so break-up is not
expected quite yet. There are no major concerns unless there is a
rapid warm up. Warming is expected toward the middle to end of
next week, though as this time, temperatures look to remain mostly
in the 50s across the Sag basin. This should be enough to finally
get breakup started up there, and we`ll be monitoring conditions
as they evolve along with the Alaska-Pacific River Forecast
Center.

Rivers and streams draining the south slopes of the central Brooks
Range including the Koyukuk will see minor rises this weekend,
but there are no concerns there or elsewhere.

&&

.EXTENDED FORECAST DAYS 4-7...
A ridge continues to build into the region Tuesday. A low in the
Gulf of Alaska will slowly weaken as the ridge builds.
Temperatures are expected to increase to normal for most of the
region by Wednesday and above normal by the end of the week.
Thursday a low moves into the Bering Sea and will push against the
ridge. This will bring unsettled weather to the West Coast and
Western Interior with showers likely and thunderstorms possible
near the end of the week.

Coastal Hazard Potential Days 3 and 4...None
