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 Juneau, AK wrote its last area forecast discussion before this small craft advisory went out at Aug 2, 2:55 PM AKDT, 12 hours 49 minutes earlier.

Area forecast discussion, Aug 2, 2:55 PM AKDT, 12 hours 49 minutes before
Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
255 PM AKDT Mon Aug 2 2021

.SHORT TERM...An upper level low over the gulf continues through
midweek. Clouds cover the panhandle. Over the Northcentral British
Columbia, our anticipated Easterly wave is moving north-west and
satellite detection is showing active convection with this band.
Believe that this will skirt past the northern panhandle this
evening.

There is some colder topped clouds starting to move towards the
southern half of the panhandle so a shot of light rain for that
section of the panhandle is possible. A more enhanced band over the
north pacific will be caught up about the upper level low and will
form into a frontal band and move onshore Tuesday afternoon and
evening.

Wednesday looks to be even a better for rain as a weaker atmospheric
river (IVT values about 400-600) is anticipated to curl in the
southern panhandle about the quasi stationary 500 mb low. Surface
level amounts of rain fall look to be in the 1-2 inch range, while
higher elevations may get a little more. Will need to watch this
over the next few shifts to fine tune rain estimates and to see if
some of the local streams and rivers may have issue. For the time
being, can expect rises in water levels but staying within the banks.

With the Tuesday frontal band, a narrow band of 25 kt small craft
over the southern outside to near southern Prince of Wales Island is
expected. Coastal communities could see gusts 20 to 30 kt.

.LONG TERM.../Wednesday through Sunday night/...An upper low with
a surface reflection will be situated over the central Gulf at
the start of this extended range forecast period. At the surface,
a front associated with the surface low will be affecting the
southern half of the Panhandle and the outer coast from Cape
Fairweather south. Models are all in agreement that this front
will affect much of the Panhandle, but differ in timing of the
push on shore and, most importantly, where and when the heavy rain
will fall. Those details represent the lowest confidence part of
this forecast. At present, the long range forecast has the
heaviest rain on Wednesday afternoon over southern Baranof Island,
Prince of Wales Island, and the Ketchikan area with the event
beginning at the tail end of the short range forecast. Categorical
PoPs are currently limited to locations from Angoon south and it
appears that the northeast gulf coast and the far northern inner
channels may be completely shut out from getting any measurable
rain from this event. By Friday the low and associated front will
have moved off to the southeast and a weak ridge will be shifting
east across the Gulf, giving us a day of dry weather. However, a
weak short wave will work its way over the top of the ridge and
increase the chance for rain once again late Friday night going
into the weekend.

Friday will feature small craft southeasterlies over the central
and southern outer coast marine zones. There is also the
potential for small craft winds over southern Chatham Strait and
Clarence Strait. These winds will relax by Wednesday afternoon as
the strongest winds retrograde to the west over offshore zone
310. Apart from this period of time, the long range forecast does
not contain any significant winds.

Daily highs were off the charts in grids with some locations
featuring highs in the 90s. Not only is this unrealistic, it was
WAY above all ensemble and deterministic model guidance. Changes
to temperatures represented the biggest change to this long term
forecast with reductions as much as 15 degrees in some cases. Even
so, daytime highs for the coming week will range from the mid 60s
to the mid 70s and quite comfortable for early August. -Fritsch
