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.

Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
523 AM AKDT Sun Oct 31 2021
.SHORT TERM.../Through Mon night/ Nothing particularly scary in
this halloween edition of the short range discussion. Some areas
of fog have formed overnight in a few areas of the inner channels.
Visibilities have dropped as low as a quarter mile at times, but
it has been rather localized and tends to shift around (adding to
the creepy ambiance). Webcam images this morning also show that
the fog banks are rather thin. Only a few hundred feet thick at
most. The rather thin and scattered nature of the fog is possibly
due to the continual stream of high thin clouds over the panhandle
from the front to the west. This fog should start to burn off
after sunrise this morning.
Warmer and dry weather remains the main aspect of the forecast for
the next 48 hours. An upper level ridge combined with surface high
pressure over northern BC are teaming up to keep the front, that
is currently over the central gulf, from moving any farther east.
There is little sign of that changing until late Mon night at
least with all the wind, and precip remaining situated over the
gulf waters. Little in the way of forecast changes as a result.
In the mean time, a warmer air mass is being pushed into the area
with 850 mb temps expected to reach 5 to 7 degrees C Today
through Mon night. This translates to high temperatures reaching
into the 40s and low 50s across a wide area for Sun and Mon
afternoon (though some areas could be cooler due to not having the
inversion break, or warmer due to downslope warming). Overnight
lows however will still drop to near or below freezing with the
clearer skies and longer nighttime hours. Fog may also become an
issue again Sun night as low level inversions develop under the
light winds and clearer skies. Though high thin clouds streaming
over the area could still limit how thick that fog will become.
Overall, any Halloween activities this evening will enjoy rather
pleasant weather across the panhandle. Dry weather is the main
story under mostly clear skies (though Yakutat will see more
clouds). Initial temps will likely be in the 40s dropping into
the 30s by late evening. Fog may become an issue through the
evening hours reducing visibility, so be careful if you are out
and about this evening.
.LONG TERM.../Tuesday through Sunday as of 10 PM Saturday/...The
long term portion of the forecast begins with a change in the
weather pattern from a drier to wetter pattern.
Starting with the weakening ridge of high pressure being replaced
with a trough. The timing of these ridge breakdowns are usually
not handled well by the models and last longer than expected. But
if current timing holds true, the ridge will break down Tuesday,
allowing for rain to slowly move in. The rain looks to come in
from the south from a pair of low pressure systems. This set up
would give SE AK a wet Wednesday.
Afterwards, a general area of low pressure will sit over the
gulf, giving the panhandle a chance at showers Thursday into
Friday.
Friday and the weekend could bring some potential active weather.
The individual runs in the models bring strong areas of low
pressure into the gulf. However, because these are 7-9 days out,
the uncertainty is high. Between the deterministic runs and the
member-wise minimums in the ensembles, the strength of the surface
low could be down to near 960 mb but the spread of timing and
travel path is very wide. So next weekend will be monitored over
the coming days.
There isn’t much for snow potential in this long term forecast.
850 mb temperatures really don't get too far below 0C so for now,
rain is likely if any precip is expected.
Highs and lows will slowly cool down during the long term. The
long term forecast starts with highs in the 40s to low 50s and
lows in the 30s to low 40s. But by next weekend, highs average in
the mid 40s with lows in the low to mid 30s.
