Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
442 AM AKDT Wed Aug 8 2018

.ANALYSIS AND UPPER LEVELS...
The trough that brought rain to Southcentral Alaska Tuesday
remains over the area as it slowly tracks east. However, the axis
has shifted just east of Cook Inlet which has shifted the majority
of the rain to the east. To the west of the trough, northwest flow
moves down the southwest coast bringing gap winds to the Alaska
Peninsula. Another system is also approaching the western
Aleutians from the North Pacific bringing a strong push of warm
air with it.

&&

.MODEL DISCUSSION...
The models are in good agreement until Thursday when they struggle
to deal with a low moving into the Bering from the south. The EC
is the fastest with this system with the NAM and GFS being slower.
However, the EC has been the most consistent with the handling of
this system and is the preferred model.

&&

.AVIATION...
PANC...VFR conditions and light winds will persist.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Today through Friday)...
A very slowly moving upper level low will bring widespread
rainfall to the Copper River Basin and Northern Susitna Valley,
with a few lingering rain showers from the Matanuska Valley
southward. As occurred yesterday around the Anchorage Bowl, cold
air with the upper level trough that has moved eastward into the
Copper River Basin may produce isolated thunderstorms from the
Wrangell Mountains to possibly as far west as the Copper River
during peak heating this afternoon. Further to the north along
the Alaska Range, the persistent heavy rainfall that developed
early Tuesday will finally begin to diminish this afternoon as the
upper trough begins to fill and drift to the south.

Starting later in the day Thursday, a weak ridge of high pressure
will begin to approach from the west, which should finally allow
for clouds and showers to begin departing the area. This ridge
will provide for what looks to be the nicest day on the horizon on
Friday as temperatures begin to rebound into the 70s for interior
areas, with light winds and clearing skies. This unfortunately
looks to be short lived as a frontal system will enter the
Western Gulf late Friday and bring active weather back to the
region for the weekend.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (through Friday morning)...
Southwest remains under the influence of a broad upper trough and
northwest flow. Since the trough axis is east of the Alaska Range,
moisture and rain is also well east of the region, so only
diurnally enhanced showers are expected today, with those showers
diminishing in the evening. Overnight, weak upper ridging starts
building in and remains in place through Thursday evening.

The next low will move into Southwest early Friday, spreading in
widespread light rain and clouds as the upper flow becomes
southwesterly.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (through Friday morning)...

A warm front and the associated low is moving into the far
southwest Bering Sea this morning. MIMIC precipitable water
values in the warm sector are high (in the 2.0-2.5" range). With
decent upper level forcing in the form of a deep but slow moving
PV anomaly, sufficient low level frontogenesis is supporting
widespread elevated convection with embedded thunderstorms. These
will impact the marine waters from the Rat Islands eastward to
Adak and Atka. The low will then lift north into the central
Bering Thu and reach the Southwest coast by Thu night, bringing
rain and 20-30 knot winds with it.

&&

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

As previously advertised, there remains good agreement once again
that Friday will at least start out dry in Southcentral, as weak
ridging moves across southern Alaska. As compared to yesterday,
the agreement has broken down regarding a weak low pushing
northeastward into southern Alaska during the day. The EC and
Canadian are holding their ground, spreading rain into Southwest
Alaska at somewhat different points during the day. Meanwhile, the
12Z GFS and the end of the NAM have both changed to take a
weaker, drier route, with no precipitation at all affecting any
areas north of a Dillingham to Homer line. Thus, the lion's share
of Southcentral and Southwest Alaska would stay dry if this came
to fruition. For now, minimal changes will be made, since the EC
has been the most consistent with it. Thus, the official forecast
for now will stay with rain overspreading areas east of the
Kuskokwim Mountains Friday afternoon, reaching the rest of
Southcentral Friday night.

Saturday is also somewhat uncertain with precipitation to start
out the day, depending on how strong the wave gets. Even the 12Z
GFS brings in additional weak upper level shortwaves by Saturday
afternoon which in turn sets off some shower activity through the
overnight. The EC remains the fastest model, showing most of the
energy moving through early in the day with the stronger faster-
moving wave, resulting in a drier Saturday afternoon across
Southcentral. The wettest solution is the Canadian, which lingers
shower activity throughout the day Saturday.

Now on to the major weather feature for the long-term, the
remnants of Typhoon Shanshan. The models are following yesterday's
EC run the closest today, with significantly better agreement,
though by no means perfect with the track. The Canadian (a.k.a.
GEM) is by far the fastest, bringing the leading edge of
associated precipitation into Southwest Alaska Saturday evening,
overspreading the rest of Southcentral by Sunday morning. Timing-
wise, this is most similar to yesterday's EC run. The 12Z GFS/EC
runs now both begin the associated precipitation very early Sunday
morning at the coast of Southwest and Kodiak, getting into the
Kenai Peninsula around sunrise, then spreads north across much of
the rest of Southcentral around midday Sunday.

A new change to the forecast with both models (especially the EC)
for Monday and Tuesday is now they suggest the parent low
drastically slows down and nearly stalls over Southwest Alaska,
which in turn keeps a steady southwest upper level flow over much
of Southern Alaska straight into Tuesday. This would keep things
very wet over all of Southern Alaska through Tuesday as the rain
transitions from a stable steady soaking rain Sunday into an
unstable showery pattern by Tuesday.
