Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
457 AM AKST Sun Feb 24 2019

.ANALYSIS AND UPPER LEVELS...
With this ridge in place over southcentral, radiational cooling
has been at its finest overnight. A number of locations hit single
digits and below zero. For much of the night, its been colder at
Ted Steven's International Airport than Deadhorse. Just before 3
AM AST a small wedge of stratus moved over the airport and the
temperature spiked a skosh at the airport, but the temperature at
the NWS Office in Anchorage remained in single digit territory
thus remaining colder than Deadhorse. To the west, there is a
surface low in the northern Bering with a mature frontal boundary
extending from it and a second low southwest of Attu Island. The
latest ASCAT/advanced scatterometer pass has detected widespread
gale fore winds with the system in the Northeastern Bering and
has detected both gale and storm force winds with the system
southwest of the chain.

&&

.MODEL DISCUSSION...
Comparing the 7z ASCAT/advanced scatterometer pass to the GFS and
NAM12 at 6Z the placement of the front in the eastern Bering and
the high over the Gulf of Alaska initialized well. The global
models are in good agreement with the synoptic features through
Tuesday morning. There are some very minor differences on the
location and intensity of the surface low moving across the
western/central Aleutians. The potential fly in the ointment will
be fog development over the Cook Inlet with that ridge in place.
There has been a lot of consistency with the longwave pattern the
past month which has had a trough over NE Russia, NW Pacific and
some portion of the Bering with a ridge over the central and
eastern Pacific and the ridge axis vacillating between the Alaskan
interior, the Yukon Territory and other Canadian provinces.
Looking at the models, expect more of the same for the next
several day.

&&

.AVIATION...
PANC...Low cigs or intermittent low cigs and light winds will
persist this morning. The Baldy Webcam has detected an area of
fog/low stratus near Knik Arm and the potential for fog or low
stratus moving over PANC is actively being monitored. At 1151Z OR
2:51 AM AST a low deck of stratus moved over the aerodrome at
PANC. The specialized satellite imagery that normally pings into
fog/low stratus hasn't detected this stratus yet, so most likely
its a microscale feature. As daytime heating occurs, the trend is
for the dewpoint and the temperature to spread farther from
eachother, and as that occurs the fog or stratus will lift and or
dissipate. &&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
(Tonight through Monday night)

An amplified upper ridge continues over the Gulf and Southcentral
Alaska through early this week. The main forecast challenge will
be the development and extent of fog. Low and mid-level warming
will tend to strengthen surface inversions and increase the
likelihood of fog develop over interior valleys, northern Cook
inlet, and across the Anchorage Bowl, during the overnight and
morning hours. Knik Arm will be the main contributor to fog across
the Anchorage Bowl. Cold air over the Copper River Basin aided by
favorable pressure gradients will continue gusty outflow winds
through Thompson Pass and the Copper River Delta into Monday. A
weak frontal boundary and southeast winds will hold the threat of
light rain or mix(overnight hours) and fog over Kodiak Island
through Monday.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2...Sunday
through Monday night)...

A stout occluded front remains in place over Southwest bringing
gusty southerly winds along the coast. Snow has already begun
falling overnight across the northern Kuskokwim Delta while
temperatures over the AKPEN and coastal areas of Bristol Bay will
allow for rain today. Although this front makes an attempt to
push further inland, a blocking area of high pressure over
Southcentral prevents the advance, forcing the remnants of the
front to retrograde back to the west beginning Sunday night.
Meanwhile, the area of high pressure will have more of an
influence over areas further inland across the lower Kuskokwim
Valley and therefore may see some areas of patchy fog develop
Sunday night into early Monday morning. As the front retraces its
steps westward early Monday, lingering precipitation is expected
to become more of a rain/snow mix. Gusty southeast winds along the
coast will persist through Monday before finally tapering off
Monday evening.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2...Sunday
through Monday night)...

The main story for the Bering is a storm force low bound for the
western Aleutians today. The leading edge of the front will
move in over the western and central Aleutians, bringing
southerly gales with a large area of embedded storm force winds.
Warm air associated with this southerly flow will allow for
precipitation to fall as rain. As the low tracks northward,
westerly storm force winds will lift over the western Aleutians
tonight. With ample cold air wrapping in on the backside of the
low, precipitation will change over to snow by Monday morning.
Currently, the low center is on track to pass just east of Shemya,
keeping the Near Islands on the colder side of the low which will
allow for snow and blowing snow through Monday morning. As the low
continues to lift northward, storm force winds will diminish to
gales over the western Bering by Monday evening.

&&

.MARINE (Days 3 through 5)...

There is a bit more divergence between the numerical guidance as
compared to yesterday, especially in the strength and timing of
the low tracking through the Bering Wed/Thu. Still, a general
consensus remains that the active pattern will persist with strong
southerly winds and significant wave heights over the Bering
through midweek. Confidence remains above average that winds and
waves will slowly diminish in intensity and height as the first
low tracks toward eastern Russia late Tuesday. Confidence also
remains high that a second deepening low moving across the
central Aleutians and into the central and eastern Bering late
Tuesday through Wednesday will bring widespread southerly gales
and wave heights building to 20 feet. The discrepancy lies in
whether this system deepens enough to produce an area of storm-
force winds across the central Bering and Pribilofs on Wednesday
before lifting north. Nonetheless, expect at the very least strong
southerly gales, and areas of rain spreading north and east
across the Bering midweek with this system. Westerly winds and
waves again relax in the wake of this system as another deepening
low brings southeasterly gales across the western Aleutians by the
end of the week.

High pressure anchored over the Gulf of Alaska will allow
generally westerly, sub small-craft winds along the coast from
Kodiak Island to Cordova through the end of the week with only
a slight chance of scattered precipitation south of Kodiak Island.

LONG TERM FORECAST (Days 3 through 7)...

The longwave trough/ridge pattern extending from the western
Bering to the eastern Gulf will remain in place through midweek.
After that, model guidance begins to diverge in how this pattern
evolves moving into the second half of next week. The GFS is most
bullish progressing the main trough east, splitting the ridge,
and bringing a phased shortwave into the northern Gulf. The EC and
Canadian, while showing something similar, is slower with the
movement of these features and holds the ridge over the Gulf a bit
longer. For what it is worth, the deterministic GFS and its
ensemble means have been inconsistent over the past 24 hours or so
with the timing, placement, and strength of the developing
shortwaves in the Bering. This has resulted in a forecast weighted
a bit more towards the EC/GEM solutions, with the ridge holding
on for now.

For Southcentral, expect the tranquil pattern to continue with a
few periods of higher clouds passing overhead as weakened
shortwaves crest over the ridge. This pattern will also lend to
persistent large diurnal temperature swings with average to
slightly below average overnight lows and slightly above average
daytime highs. The biggest challenge to the forecast will
continue to be fog, especially as the high drifts to the east
through next week. A southerly flow on the back side of the ridge
could advect just enough moisture to combine with the overall weak
surface flow to allow overnight/early morning fog to develop
along Cook Inlet and portions of the MAT-SU and Copper River
valleys. The southerly flow may also bring moisture to produce a
few scattered showers across Kodiak Island by the end of the week.

For the AKPEN and southwest coast, expect periods of strong
southerly winds and precipitation (mainly rain) as the occluded
fronts attached to lows tracking north across the Bering slow and
weaken as they to push inland and run up against the ridge. The
first of these will impact the coast late Monday through Wednesday
before drifting east across the southwest interior. The second
arrives overnight Wednesday and lingers through early Friday
before weakening as it, too, drifts east. Behind it, a ridge then
attempts to build in for the weekend.

For the Bering and Aleutians, one departing low will give way to a
second, gale-force low tracking north across the central Aleutians
and into the Bering beginning early Wednesday. Expect strong,
southerly gales (with areas of storm force winds possible) moving
northeast from the central Aleutians to the Pribilofs and eastern
Bering. Broad, westerly small-craft winds and areas of showers
continue across the Bering late week as this second storm lifts
north and a weaker shortwave slides underneath the main low.
Southeasterly gales redevelop along the western Aleutians by the
weekend as another deepening NOrth Pacific low tracks east toward
the chain.
