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 Apr 28, 2:47 PM AKDT, 13 hours 8 minutes earlier.

Area forecast discussion, Apr 28, 2:47 PM AKDT, 13 hours 8 minutes before
Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
247 PM AKDT Wed Apr 28 2021

.SHORT TERM.../Through Thursday night/...A front lies situated
over the southern half of the Panhandle as of this afternoon and
rain has been steady over the southern inner channels, the
southern outer coast, and Misty Fjords all day. So far, the
precipitation has been light, but that is expected to change by
this evening. Although the rain will spread north through the
night, the most widespread heavy precip is expected to remain
south of Sumner Strait. Moving on to tomorrow, heavy rain is
expected to spread north to the Icy Strait corridor. A warmer low
level airmass is advecting in from the south with this front, and
Thursday looks like it will be the warmest day through the end of
this work week. Look for temps to reach the lower 50s in many
locations. After Thursday, a cooler airmass will move in from the
west. Even with tomorrow's relative warmth, higher elevations,
such as the Juneau Ice Field, will remain at or below freezing, so
P-type will be snow vice rain on top of existing snow. This will
aide in preventing large scale snowmelt and attendant flooding
concerns. To be certain, there will be rises on Panhandle
waterways, particularly over the southern half, but there are no
flooding concerns at this time.

Winds associated with this weather system are not very impactful,
with only marginal small craft conditions at times over the
eastern Gulf, Clarence Strait, and Cross Sound through Thursday
evening. By late Thursday night, conditions over Lynn Canal will
increase in the post frontal southerly pressure gradient.

Forecast changes today included a slight reduction to inner
channels winds for much of the time, but an increase over the far
northern inner channels late Thursday night. QPF was studied
closely and in coordination with the River Forecast Center in
Anchorage. Blended in the current high resolution model data to
existing grids and the resulting solution produced a little more
storm total precip than the previous forecast. 36 hour totals
ranging from less than 1/2 inch over the northeast Gulf Coast and
far northern inner channels to more than 3.5 inches over the
southern inner channels and Misty Fjords. Overall short term
forecast confidence is average.

.LONG TERM.../Friday through Wednesday as of 10 pm Tuesday/ A wet
pattern with high temperatures at or slightly below normal looks
to continue for the foreseeable future. Night time low
temperatures should be above climate normals during this time
period. We begin the period with low pressure off the coast,
weakening from a closed low into a trough. Winds may be a bit
elevated, especially along coastal areas and the northern inner
channels, during the first several hours of this forecast period,
but have opted not to go all in quite yet as timing of the low
weakening and the loosening of the associated pressure gradient is
still up for debate amongst the various model solutions. After
this low becomes a non-factor, ridging will begin to build over
the region for the weekend. Flow will be onshore, so expect
showers to continue through the weekend and cloud cover to
continue to be pervasive. By Sunday, showers will become more
spread out and while far from certain, there may be enough breaks
in the clouds to get some of us hints of sun during the day. After
the weekend, another low pressure system begins to move in on the
region. Timing and intensity of this system is still pretty much
up in the air but have opted to trend toward the WPC forecast for
guidance. Toward the end of the forecast period, yet another low
begins to move toward the region. Again, I reiterate that the
models are not coming to a consensus, but if the latest
operational GFS is to be believed this event will be quite a wind
and rain maker. By no means has this made it into the current
forecast, but it will be something to keep an eye on for future
consideration. Regardless, the trend of clouds moderating the
temperatures and continued rainy, unsettled weather looks to
continue through the duration of the forecast.
