Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
341 PM AKDT Tue Jun 11 2024

.SHORT TERM.../ Through Wednesday night / Quiet weather across
much of the SE AK panhandle. The low that passed south of Haida
Gwaii moved into British Columbia and spread some clouds into the
southern third of the panhandle and a bit of light rain from the
part of frontal band that pushed to the Dixon Entrance area.
Along the western portion of the remaining panhandle clouds which
were pushed onshore are catching on the terrain and then moving in
the flow along the coastline towards the Northeast Gulf coast.
The northern inner channel regions got a few more breaks in the
clouds and warmer high temps.

Widely scattered shower may continue tonight and into Wednesday
and Wednesday evening. Better chance still over the southern
portion of the panhandle with some moisture flow from Central
British Columbia into the southern panhandle into Wednesday and
Wednesday night. Patchy fog could also develop overnight in areas
with sufficient moisture, and supporting conditions. Am not
anticipating widespread fog development.

.LONG TERM...For the end of the week, we expect to have a low continuing
to meander around the BC coast and southern panhandle that should
bring some showers to parts of the panhandle. This could also
bring some thunderstorms to the border and areas around the border
for the weekend. As this low slowly moves out of the area, high
pressure will remain off to the west allowing for NW flow across
the gulf. Temperatures across the panhandle are also expected to
respond to the mild weather with some increasing warmer
temperatures as well. This will make things feel more like summer
instead of feeling like spring. For the extended into next week,
conditions are expected to be more likely warmer and drier for
most of the panhandle according to the Climate Prediction Center.

Big changes to the long term forecast today are a continued decrease
in winds across the area as well as the introduction of a few
possible thunderstorms during the day on Saturday.

.AVIATION...Generally good flying weather for the next 24 hours
with conditions ranging from 1000ft to clear & 7. Lowest CIGs
associated with rain showers over the southern Panhandle and
onshore flow over the northeast Gulf Coast. Convective build-ups
clearly seen on visible satellite imagery and a noticeable lack
of cloud cover over the inner channels. These clouds will diminish
as nighttime approaches. Overnight radiational cooling where
skies remain mostly clear is expected to result in some fog, but
should not be enough to affect operations and any of the TAF
sites. Freezing level is right around 5000ft, so instrument flight
over higher terrain will likely result in some airframe icing.
Low level wind flow will be light, so any turbulence out there
will be a result of convective thermal activity - which will end
with the end of daylight. Setup across Southeast Alaska basically
the same for tomorrow: wash, spin, rinse, repeat.
