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 Jul 19, 2:38 PM AKDT, 13 hours 21 minutes earlier.

Area forecast discussion, Jul 19, 2:38 PM AKDT, 13 hours 21 minutes before
Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
238 PM AKDT Mon Jul 19 2021

.SHORT TERM...Afternoon satellite imagery shows partly cloudy to
mostly clear skies over a large portion of the central Panhandle
as of this afternoon. Low level offshore flow has eroded marine
layer cloudiness on the outer up to Cape Fairweather. Yakutat Bay
is clearing out from the north as well so there is hope that
Yakutat may see some sun later this afternoon before the marine
layer moves back in. The overall trend, however is for increasing
clouds from the south with the present area of mostly clear skies
moving northwest towards Yakutat by tomorrow.

The low southwest of Haida Gwaii is still out there, but its
influence on the weather over the southern Panhandle is greatly
diminished. Looking at IR and water vapor imagery, it does not
seem as if it is contributing much at all to the easterly wave
shower activity that continues to stream over the area. In fact,
observations today have not reported any showers. That is expected
to change tomorrow with showers becoming more likely through the
day over the southern zones and those zones close to the coast
mountains. Afternoon thunderstorms have developed across a large
portion of the Yukon as of this writing, but those are forecast to
remain in the Canadian side of the border north/west of Skagway
and Haines. Likewise across the northern tier of British
Columbia, where an enhanced easterly wave oriented east to west
has persisted all day. The general motion of this feature is
northwest, so those thunderstorms are forecast to remain clear of
the Panhandle as well. The situation changes a bit for Tuesday
afternoon and evening. By then, instability and other thunderstorm
ingredients are forecast to result in some thunderstorms over the
far northern inner channels, between Taku Inlet and Tracy Arm,
and across Misty Fjords to near Ketchikan.

Seasonal temperatures will prevail for this short term forecast
period with daytime highs ranging from the lower to the upper 60s
with 70 degrees possible for Skagway, Haines, and Juneau on
Tuesday. Overnight lows will trend slightly above normal due to
increasing cloudiness.

.LONG TERM...Wednesday through Monday as of 10 PM Sunday. Forecast
reasoning is generally the same as last night since not much has
changed with the model guidance. Easterly wave activity leaves the
central Alaskan Panhandle just before a front approaches the
Panhandle, bringing more of a stratiform rain event into the
Panhandle into the weekend.

Generally, onshore flow from the ridge located over the far
eastern Gulf and Panhandle will be present for into Thursday
morning, yielding more showery type of activity until then. The
ridge will sharpen over the Panhandle through Thursday morning
before it gets pushed eastward out of the area. Additionally,
unimpressive IVT values indicate no real threat of an atmospheric
river with the front toward next weekend.

As for winds, as the front approaches, they were marginally bumped
up for the Thursday into Friday morning timeframe. Winds of up to
25 to 30 knots are possible just off the outer coast before it
comes ashore. Through the rest of southeast Alaska, winds look to
remain comparatively light at around 15 knots or less. Higher
pressure will be poised around the southern Yukon Territory /
northern British Columbia area for the majority of the period.

Daytime high temperatures look remain on the mild side across the
Panhandle through the long term forecast period, but cooler than
the past several days, which were well into the 70s to near 80
degrees. High temperatures will primarily be in the 60s for the
period. The warmest temperatures will be near the Skagway /
Northern Lynn Canal area as they will have a bit less cloud cover
with mainly broken to scattered skies, much less rain chances
through the period, and a chance of some mild downslope winds from
higher pressure positioned to the northeast. Skagway's highs look
to remain close to 70 through the period. Generally, the farther
south that you go through the Panhandle, clouds and precipitation
chances are higher throughout the period either with the easterly
wave activity for the first day of the period through the central
Panhandle, lighter activity across the southern Panhandle
associated with a weakening low coming ashore around the Graham
Island, British Columbia area for the first day of the period, or
the approaching low and associated front moving in from the Gulf,
which will bring more persistent stratiform rain into the
weekend.

There is some minor disagreement compared with yesterday on the
positioning and strength of the low and associated front as it
approaches the Panhandle, but they were generally in good
agreement. Therefore, forecast confidence is average.
