Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
955 AM AKDT Wed Aug 27 2025

.UPDATE...Update to the aviation section to include the 18z TAF
issuance.

The short term forecast remains on track from this morning as fog
has begun to dissipate and clear skies continue for a majority of
the panhandle. The NE gulf will continue to see overcast skies
with the potential of lower clouds as a weak trough moves over the
area. Winds overall will remain light with sea breezes developing
late this morning into the afternoon increasing isolated areas up
to 15 mph.

&&

.SHORT TERM...Conditions this morning are starting out very
similar to yesterday morning with light winds being reported
across most of the panhandle with the exception of a few areas
over the water in the Inner Channels. Some clouds continue to move
over the Yakutat area while mid level clouds have developed in
the Northern Panhandle this morning. Some patches of fog are
present this morning with the most significant fog being located
in the Klawock area. Temperatures today should continue to be
similar to yesterday with most locations getting into the 60s and
70s. Right now, any place that is likely to see any rain would be
west of Yakutat along the northern Gulf coast towards Cape
Suckling. Otherwise dry conditions are expected to continue for
the short term.

.LONG TERM.../Thursday through Sunday/...
Key Messages:
- High pressure over the gulf continues warm, dry weather for
  a majority of the panhandle
- Areas of the southern panhandle will see high temperatures
  reach 80 Thursday

Broad upper level ridging continues to extend through the gulf
and over the panhandle through the week, helping to direct surface
flow up and over the panhandle. This will keep the panhandle dry
and warm through the week, with clear skies in the south and
partly cloudy skies in the north. Yakutat may experience more
cloud cover and potential for rain as the remnants of a system in
the southwestern interior attempt to push through the northern
coast. Outflow winds will remain light through the southern
panhandle, with Icy Strait and Lynn Canal seeing stronger inflow
winds due to sea breezing and a tightening pressure gradient over
northern Lynn. This also means winds will diminish overnight,
allowing for fog to develop in sheltered areas and a marine layer
along the outer coast to push into channel entrances.

850 mb temperatures aloft have continued to increase to 14 to 17
degrees Celsius for Thursday and Friday, allowing for surface
temperatures to reach into the 70s for most of the panhandle.
Temperatures in the southern panhandle are expected to reach near
80 degrees, with inland areas feeling the warmest temperatures as
they are not susceptible to sea breezes. A heat advisory has been
issued for communities in the southern panhandle through Thursday,
though this may be extended as it gets closer. Remnants of an
interior panhandle front look to reach the northern outer coast
again over the weekend, though this system may have enough energy
to push more into the panhandle. Rain accumulations are expected
to remain light, though Yakutat may see heavier totals due to a
potential weak atmospheric river trying to move over the northern
coast. This system at the very least will bring some more cloud
cover and in turn slightly cooler daytime temperatures going into
next week.

.AVIATION...Quiet Aviation weather continues today with mostly
clear skies and only a few isolated areas of overcast skies near
the northern coast. The NE gulf coast may see some of that cloud
cover lower to around 2500 ft this morning due to a weak trough
moving through, but ceilings there are expected to rise back to
VFR by late afternoon. For the rest of the panhandle, VFR
conditions are expected to continue through tonight. Some
isolated fog or low clouds could return late for areas around
Cross Sound for the north, and near Klawock again for the south.
Little in the way of winds to worry about expect for localized
stronger sea breezes in the afternoons. The strongest sea breeze
will be located near Skagway with winds increasing to 10 to 15 kts
with gusts to 25 kts.

.MARINE...

INSIDE WATERS...Light to gentle breezes continue this morning
although there are some areas of isolated moderate breezes for the
Inner Channels. These isolated areas are mostly confined to
Sisters Island over Point Couverden as well as Point Gardner.
otherwise, conditions remain light with only some areas of fog
possible this morning. Winds are expected to increase later today
as sea breezes return to the area. Otherwise conditions today are
expected to be similar to yesterday.

OUTSIDE WATERS...High pressure continues to remain over the
eastern Gulf this morning bringing west winds to the Cape
Fairweather area while farther south, NW winds are being reported
at Cape Edgecumbe. As high pressure shifts to the east more in
response to a low moving north towards Prince Williams Sound,
winds are expected to decrease. Farther north and west towards
Cape Suckling, winds are out of the east this morning and are
expected to remain out of the east in response to the low passing
by. Wave heights across the Gulf area expected to remain fairly
small today as quiet weather continues for most of the Gulf
waters.
