Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
446 AM AKDT Sat May 5 2018

.ANALYSIS AND UPPER LEVELS...

Ridging remains over western Canada, while a vertically stacked
low sits behind it over the Y-K Delta. This low that brought
breezy conditions over the past day to the Kenai Peninsula and
Turnagain Arm is now pulling cold air from the Bering into
Southcentral. An amplified 130 kt jet is directed at Southcentral
from Prince William Sound eastward, bringing a subtropical
moisture fetch to the north Gulf coast from the atmospheric river
in the North Pacific.

The Kenai Peninsula and Prince William Sound have both seen
decent amounts of rain in the past day. Currently heavy precipitation
remains along the north Gulf coast and is switching over from
rain to snow in Valdez, as the moisture is shifting eastward as
the cold front passes over the area.

&&

.MODEL DISCUSSION...

The numerical models are in excellent agreement with the large
scale synoptic pattern through the middle of next week. The
pattern is relatively stable as the strong low which moved into SW
Alaska yesterday slowly weakens. Meanwhile, over the Bering Sea,
a rather strong (for this time of year) near storm force low is
also being well-modeled by the guidance with little spread among
the model members. Forecast confidence is high.

&&

.AVIATION...
PANC...Gusty southeast winds are expected to remain at the
terminal through the forecast period. Intermittent showers will be
a threat as well, but conditions are expected to remain VFR.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
The main bulk of the precipitation that is currently spread from
Prince William Sound eastward will push east today and be in the
Panhandle by the afternoon. Broad southwesterly flow aloft will
continue to bring showers to the area through Sunday evening.
Showers will increase across the Cook Inlet area through the
Matanuska and Susitna valleys Sunday afternoon and evening as an
upper level short-wave moves across the area from the southwest.
Showers will then diminish or end from west to east Sunday
night behind this short-wave as the flow aloft becomes westerly.
Breezy conditions will continue over much of Southcentral through
Saturday as the low centered near the Yukon Delta slowly moves
north. Winds will then become fairly light on Sunday as surface
high pressure builds over the area.

&&

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

A northward drifting, vertically-stacked low continues to spin
over the Y-K Delta this morning. Colder air advecting in behind
this occluded system is helping to keep the atmosphere
destabilized. This will result in a continuation of widespread
mixed precipitation from the Kilbuck Mountains on north through
early Saturday. Mixed precipitation will also continue to push
northeast from Bristol Bay through the Nushagak River valley and
northern AKPen as a trailing surface trough east of Cape Newenham
slides into SW AK by mid-morning. Scattered snow showers will
continue over SW AK through Sunday afternoon as two upper-level
shortwaves pinwheel through SW AK, keeping the region in a moist,
westerly flow and enhancing instability. A fast-moving ridge of
high pressure sliding across the eastern Aleutians will provide a
brief respite from the unsettled weather Sunday evening through
the first half of Monday before clouds begin to overspread the
area in advance of the next warm occlusion lifting up from the
central Aleutians.

&&

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

Cold air continues to spill southward over the Bering and across
the Aleutians as the first low continues to spin slowly northward
across the west coast of mainland Alaska. Gusty north winds along
with a shortwave digging south through the central Bering today
will trigger numerous snow showers for the Pribilofs and the north
side of the Aleutians and Alaska Peninsula through late Saturday.
Conditions will briefly improve across the central and eastern
Aleutians overnight Saturday through Sunday morning as a
deepening low well south of Shemya amplifies a building ridge of
high pressure downstream.

For the western Aleutians, conditions will quickly deteriorate
overnight Saturday and into Sunday as rapidly strengthening low
pressure brings another shot of gale-force winds, warm air, and
rain to the region. By Sunday afternoon, this low will deepen to
970 mb and swing a warm occlusion ahead of the center of
circulation. The front will move quickly through the central
Aleutians, nearing Cold Bay by Sunday evening. Widespread
precipitation and gales will encompass much of the Aleutian chain,
Bering Sea, and western AKPen as this system becomes the dominant
weather feature through the first half of next week.

&&

.LONG TERM FORECAST (Days 3 through 7: Monday through Friday)...

On Monday, surface high pressure will build across the Gulf,
extending northward across much of Southcentral. This will be the
cause of a rare wind-free, precipitation-free, partly cloudy day
for most of Southcentral. Outdoor plans should definitely be made
for Monday. Meanwhile, for Kodiak and most of Southwest Alaska,
the next front will move in on Monday, though not reaching Kodiak
until late in the day. The front is associated with a sprawling
low, the center of which is expected to be about halfway between
Adak and the Pribilofs Monday afternoon.

On Tuesday, the Bering low remains in roughly the same area as on
Monday as it stalls. However, the front will continue drifting
slowly eastward, thus, the coast from Prince William Sound west
will see rain developing through the day, but the front will start
up the gap winds, so areas downwind of the Kenai Mountains and
Anchorage will stay dry, albeit cloudier than Monday. Meanwhile
points north and east of Anchorage will remain dry as well, but
that will be simply because the front doesn't make it that far.
Rain, heavy at times, will be likely on Tuesday from Kodiak
northward to about Seward.

From Wednesday onward, the models diverge significantly as to how
the front behaves. The GFS and EC keep the front largely
stationary, holding the heaviest rain in about the same areas as
on Tuesday, with relatively little rain for northeastern Prince
William Sound and points north and east. Downsloping continues to
keep the Anchorage area mainly dry regardless. The Canadian model
advances the front across the area, so all of the Gulf Coast gets
hit with rain on Wednesday. The GFS/EC solution brings the
remnants of the front into the rest of the Gulf Coast on Thursday,
which in its highly weakened state would diminish the downsloping
enough for the Anchorage area to potentially get in on the
rainfall action.

Meanwhile the low over the Bering dissipates in place on Thursday
with its remnants absorbed into a new low moving north out of the
Pacific towards the Alaska Peninsula. With the easterly flow
continuing, western Prince William Sound will remain wet
throughout Friday, while the rest of the area north of Kodiak
starts out the day dry. The next round of precipitation with the
associated front reaches the north Gulf Coast by Friday evening.
The models are in surprisingly good agreement on the behavior of
the front on Friday considering the previous days (Wednesday and
Thursday), there is far more disagreement.
