Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
502 AM AKDT Wed Aug 30 2017

.ANALYSIS AND UPPER LEVELS...
A broad 980 mb low centered over the northern end of Kodiak Island
remains the primary driver of the weather pattern across southern
Alaska this morning. Deep onshore flow and orographic enhancement
along the coastal mountain ranges is keeping the bulk of the rain
focused over the North Gulf Coast, with downslope flow helping to
keep inland portions of Southcentral AK mostly dry. Rain has also
spread west into portions of Bristol Bay and the Lower Kuskokwim
Valley as what's left of the front continues to push inland. The
Bering Sea remains locked in a fairly benign northerly flow
pattern between the Kodiak Island low and high pressure building
in from the west, although some gusty winds are present from the
Pribilof Islands eastward to the coast as the pressure gradient
tightens between these two features.

&&

.MODEL DISCUSSION...
Models are in generally good agreement through the end of the work
week as the upper trough over the Gulf lifts slowly northward into
Southcentral AK, with the surface low over Kodiak Island
eventually moving into the Upper Cook Inlet region and dissipating
by Thursday night. This will keep abundant rainfall focused along
the Gulf Coast, with showery conditions prevailing elsewhere
across the southern mainland as shortwave energy from the Arctic
helps to reestablish the longwave trough farther to the west over
the Y-K Delta region by Friday. Mainly utilized a NAM/GFS blend
for the morning forecast package.

&&

.AVIATION...
PANC...Strong downslope flow is expected to keep any showers away
from the terminal through the TAF period, although a few showers
may develop elsewhere in the Anchorage Bowl. VFR conditions are
expected to persist through Thursday morning. Gusty southeast
winds may make it into the terminal during the afternoon as the
down inlet pressure gradient slackens a bit.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
The weather around Southcentral Alaska will be slow to change
much over the next few days with the longwave trough over the
area. The surface low over Kodiak Island will stay nearly
stationary through tonight and then move up Cook Inlet tomorrow
and be absorbed into a low in the interior. This basic situation
will be happening at the upper levels as well.

What all this means for the forecast is that the downslope on the
lee side of the Kenai, Chugach, and Talkeetna Mountains will
continue today keeping most of the rain showers away with the ones
that make it through only producing light rainfall. The north
Gulf Coast will see a number of inches of rain over the next few
days with the focus shifting from eastern Prince William Sound to
Western Prince William sound and the eastern Kenai Peninsula.

As the low lifts northward on Thursday and Thursday night it will
cut off the downslope and likely bring some rain into the lee
side areas that are currently in the rain shadow so POPs for those
time frames were increased over upper Cook Inlet and the Mat-Su
regions.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
The very slowly moving upper low over Kodiak Island along with a
separate trough descending down the west coast will be the focal
points for widespread rainfall over much of the Southwest today.
The exception to this will be over the Kuskokwim Delta as a very
abrupt break in the western edge of the rainfall has developed
just to the east of Bethel. As a result there is increasing
confidence that areas from Bethel west will remain dry with even
some sunny breaks and continued gusty northerly winds during the
day today. This agreement begins to break down this evening-
Thursday as the upper trough approaches. Further east over the
Kuskokwim Valley and Bristol Bay, cold air associated with the
upper level trough moving into the area will cause for the rain to
redevelop throughout the area by this evening, then persist for
most of the day Thursday. This active pattern will then continue
into Friday as yet another upper trough quickly moves overhead,
bringing clouds and rain to much of the region into this weekend.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
Northerly flow will continue over much of the region today,
however overnight satellite imagery indicated more stratus
development than initially expected, so most areas won't see as
much clearing as first thought today. Showers will then spread
into the Central Bering by this evening as a weak trough moves
through, which will then spread into the Aleutian chain late
tonight. Over the Western Aleutians, a weak frontal system will
bring rain to the area for Thursday ahead of a stronger low
expected to impact the area for Friday.

&&

.LONG TERM FORECAST (Days 3 through 7)...
More cool and wet weather is expected. A highly dynamic pattern
is on tap for this forecast period with broad troughing
influencing the entire state. This weekend expect a low north of
the Western Aleutians concurrent with a pair of lows over the
mainland. As time elapses expecting southwest flow to set up over
the AK Peninsula with moisture being advected into southcentral
AK. This forecast package, the pops where bumped up to reflect the
run to run consistency with the ECMWF with regard to the trio of
lows and the sensible weather highlights.
