What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Anchorage, AK wrote its last area forecast discussion before this small craft advisory went out at Jul 31, 4:47 PM AKDT, 10 hours 44 minutes earlier.

Area forecast discussion, Jul 31, 4:47 PM AKDT, 10 hours 44 minutes before
Southcentral and Southwest Alaska Forecast Discussion
National Weather Service Anchorage AK
447 PM AKDT Mon Jul 31 2017

.ANALYSIS AND UPPER LEVELS...
Today's weather pattern is dominated by a few key features. To
begin, high pressure across Canada and into Alaska is slowly
beginning to retreat. An upper level low and attached surface low
are churning away in the Gulf of Alaska. Water vapor analysis
shows a that this low is tapping into Pacific moisture near the
30th parallel. Farther West are two distinct shortwaves heading
towards the mainland. The first is riding along a ridge across the
southern Bering while the other is diving down from Siberia. Both
of these features will come into play bringing weather across the
AOR.

&&

.MODEL DISCUSSION...
Overall synoptic model agreement is strong through about days 2
to 3. It is in that timeframe that there is some disagreement with
models in the upper levels and how they transition a digging
trough across the Bering. Guidance is somewhat similar to the
intensity of the trough, surface low (and attached frontal
features) but the biggest difference is in timing. The Canadian
solution is by far the quickest. The GFS and EC are lock and step
with about a 12 hour lag. The NAM is the slowest yet, but is still
painting a similar picture. Beyond 84 hours - features get pretty
messy to decipher and confidence in finer details begins to
decrease. Short term forecasts were tied close to the NAM for
today's forecast package.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)...
Most of the area will move into a cloudier and cooler pattern by
late tonight as an upper level trough approaches from the
Southwest Mainland. Ahead of this trough there remains some weak
instability along the southern edge of the thermal trough which
may produce a few thunderstorms along the higher elevations of the
the Copper River Basin this evening, however development so far
this afternoon has been very weak so significant convection is not
expected. Rain will then begin moving into the Gulf Coast late
tonight as a weak low approaches the southern Gulf. Widespread
wetting rains will then spread into Southcentral for Wednesday as
an upper level shortwave approaches from the west.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)...
There is a weather front slowly moving from west to east as it
tracks across the Kuskokwim Delta this evening. This is bringing
widespread rain accompanied by southerly flow before spreading
eastward into the Lower Kuskokwim Valley, and the Bristol Bay
region by late evening tonight. Meanwhile, an upper level trough
tracks off the northern Bering into the Kuskokwim Delta by Tuesday
afternoon. This brings another round of wetting rains to the
aforementioned region before pushing into the Lower Kuskokwim
Valley, and the Bristol Bay area by Tuesday evening time-frame.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)...
The majority of the Bering Sea/Aleutians is influenced by a ridge
extending from a North Pacific high pressure located near 46N
174W. This is producing a westerly flow with widespread marine
layer stratus accompanied by fog. While the northern/eastern
Bering has a front tracking eastward as it continues to push
inland over the Southwest Alaska region this evening. While
upstream a 1005 mb North Pacific low tracks just southwest of
Shemya by Tuesday morning. The associated front will enter the
Western Aleutians during the same time-frame bringing a large
swath of rain with gusty southerly winds. This system tracks into
the western Bering by late Tuesday night with the winds shifting
more southwesterly through the Central Aleutians, and the Bering
Sea.

&&

.LONG TERM FORECAST (Days 3 through 7)...
The long term will first be characterized by high pressure over
the Gulf that will extend over Southcentral Alaska and troughing
to the west that will bring rain to the Eastern Aleutians and
Southwest Alaska. This pattern will hold into the weekend but on
Sunday the pattern will shift with a low moving south of the Gulf
and ridging building in over the Bering and Aleutians. This will
leave southern Alaska in unstable conditions for early next week
with afternoon convection possible.
