.ANALYSIS AND UPPER LEVELS...

There is a shortwave ridge axis moving east across the ALCAN as a
shortwave trough lifts northeast across Southern Alaska. This
trough is supporting a mixed bag of precipitation with mainly snow
over interior locations of Southcentral and mixed rain/snow along
the coasts. Current Kenai radar imagery clearly depicts the back
edge of this trough axis quickly moving up Cook Inlet, and The
parent low is over the Bering Sea, with the strongest pressure
gradient along the Southwest coast of Alaska. Over the North
Pacific, a low is forming south of the Eastern Aleutians along the
periphery of a sharp baroclinic zone with the associated surge of
warm air advection forming an impressive baroclinic leaf on
satellite imagery. This low is going to be a major factor in
weather across Southern Alaska through Monday, bringing a wide
range of impactful weather to the region.

&&

.MODEL DISCUSSION...

The numerical models are in excellent agreement with the large
scale pattern through the middle of next week. They are also
in very good agreement with the track of the aforementioned North
Pacific low moving into Southern Alaska today through Monday as
well as a near storm force front moving into the western Bering
Sea Sunday night and Monday. Although they are in good agreement,
there are still significant challenges with the storm moving into
Southern Alaska in relation to the models and the small details.
The biggest challenges will be precipitation type across parts of
the region as warm air pushes north and erodes the cold air which
has been in place for the past couple weeks. This forecast favors
the hi-res models for winds and precipitation.

&&

.AVIATION...
PANC...Snow showers have moved away from the terminal this
morning, but steady snow is expected to return this evening and
early tonight. However, southeast winds will increase overnight
and will eventually allow for enough warm air to change
precipitation to periods of rain mixed with snow heading into
Monday morning.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...

The weak baroclinic boundary moving across Southcentral this
morning is the beginning of a significant pattern shift which
will bring windy and wet continues across Southcentral through
early week.

As the upper ridge retreats east today the long wave trough over
the eastern Bering Sea digs and sets up broad southerly flow
across Southcentral tonight which continues through Monday. At
the surface, a moderately strong low moves north across the Ak Pen
late this afternoon and into Southwest Alaska tonight. While its
associated frontal trough moves into the western Gulf this
afternoon and into Southcentral tonight before exiting to the east
late Monday. The moisture will surge north across Southcentral
with the onset of strong southerly flow aloft and advancing
surface front. Significant snowfall is expected across the
Susitna Valley and Talkeetna mountains tonight and Monday along
with Valdez area and the coastal mountains. Significant warming
will accompany the front and will give rise to widespread mixed
precipitation types across the Kenai Peninsula and Cook Inlet
regions this evening. Snow should mix or become predominately rain
across the Anchorage Bowl and portions of the Matanuska Valley
Monday. Weak cold advection on the backside of front brings a
parting shot of snow across Cook Inlet/Anchorage Bowl Monday
evening.

Pressure gradients will be intensifying through this afternoon and
tonight with the approach of front and will generate generally
windy conditions along with brisk/strong gap flows (Turnagain
Arm, Portage Valley, Knik River Wind, Copper River, etc.) which
will hold into Monday afternoon. Cold advection Monday
night brings westerly gales to the western Gulf and strong
outflow winds to the eastern Kenai Peninsula and Western Prince
William Sound.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...

A progressive pattern is on tap this forecast period. The longwave
pattern features a trough axis over the Aleutians along with a
shortwave north of Toksook Bay and a separate cluster of energy
approaching the AKPEN. As of 13z or 4 AM AKST there is a line of
showers on the Bethel radar (PABC) from Eek to Russian Mission.
The orientation of the showers on PABC doesn't match any of the
projected QPF fields for that time. Right off the bat, we know
there are some level of uncertainty. But as the shortwave lifts,
expect the showers to follow. There will be a brief lull before
the next wave of precipitation. A second shot of moisture will
continue to push towards Southwest today as a warm front moves
into the region. Temperatures in some locations may reach the
upper 30s and possibly even 40F. This system will track up
Kuskokwim Bay and the west side of the Kuskokwim Mountains late
tonight into Monday morning. There is high confidence that this
will be a stratiform event but there is some uncertainty about the
transition time between rain and snow. At this time, did not issue
any winter weather headlines.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...

The forecast period commences with a decaying low near the
Pribilof Islands. This system will slowly push northward. A new
surface low will cross 50N this morning and is head directly for
the AKPEN. The models have a good fetch of sub-tropical moisture
associated with this system. The other attribute that jumps out
about this storm is all of the warm air advection associated with
it. For the Eastern Aleutians expecting all rain. West down the
Chain, a ridge axis will move over Adak and will be over Unalaska
Monday morning. Thirdly, a strong front moves into the western
Bering and Aleutians late Sunday night, traversing much of the
Bering by Tuesday morning. This system is expected to bring gale
force winds and rough seas to the region.

&&

.LONG TERM FORECAST (Days 3 through 7)...
A change to a warmer pattern remains in store for the beginning
of next week. On Monday, a low pressure system approaches the AK
Pen from the North Pacific and then moves into the eastern Bering
Sea. This system is accompanied by a lot of warm air, which makes
precipitation type a challenge for Monday's forecast. Models have
been somewhat inconsistent with the track of this low as well,
finally coming into some agreement with this morning's 18Z run.
Current forecast keeps a more southerly flow aloft, which
indicates a greater chance for precip reaching the lee side of the
mountains. This will also prevent a true snow-eater Chinook in
Southcentral, but some liquid precipitation is expected with
temperatures rising into the 30s at the surface.

On Tuesday and Wednesday, a short wave ridge will move through the
region, temporarily clearing skies first in the eastern Bering,
then over the mainland. This ridge is followed by a series of low
pressure systems that move into the central and western Bering.
Models forecasts have been very inconsistent on these next
systems, so there is little confidence in specific storm tracks
and timing past Wednesday. Overall though, an active pattern
looks to persist over the Bering and Western AK while high
pressure builds over Southcentral leading to quieter weather by
the middle of next week.
