Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
247 PM AKDT Wed Jun 12 2024

.SHORT TERM.../Through Thursday night/...Little in the way of
impactful weather for this short term forecast period. Most
notable item is the possibility of heavy rain showers on Thursday
night over Juneau as an easterly wave moves through the area.
Looked at the possibility for thunderstorm activity associated
with this feature, but decided against including them due to the
event being late at night and crossing the ice field - both of
which work against vigorous convective activity.

Daytime highs are still trending below normal with values ranging
from the mid 50s to low 60s under partly to mostly cloudy skies.
Overnight lows will be getting down to the low to mid 40s.

.LONG TERM...For latter half 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 Friday through 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 were the introduction of
more chances of an isolated thunderstorm along the Coast mountains
up to White Pass and over towards Haines Pass.

&&

.AVIATION...For the TAF period, VFR conditions are expected to continue
across the panhandle. Some lowered ceilings are possible but
these are not expected to be impactful. Otherwise, with the
clearing skies and warming temperatures, sea breezes are expected
to continue until sunset then should calm down. With similar
weather expected tomorrow, expect the sea breeze to become active
again by mid- morning tomorrow.

&&

.MARINE.../Through Thursday night/...Lightweight summer conditions
with little in the way of impactful winds...except for Lynn Canal.
There, southerly winds of 20 kts this evening will diminish
overnight. Similar situation for the eastern Gulf of Alaska: SE 15
to 20 kts with seas 7 ft or less.
