Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
940 PM AKST Sat Dec 27 2025

.UPDATE...Looking at the latest observations, along with the latest
radiosondes available in Annette, WAA has taken over the southern
half of the panhandle. Most areas have either transitioned fully to
rain or heavy mixed precipitation in sheltered areas. Stronger winds
have also moved in, with SE winds in Metlakatla up to Kake
increasing with gusts up to 45 mph. With strong WAA, cut down on
snow accumulations in Juneau. Given the latest snow accumulations
for Juneau and surrounding areas, and the incoming warm air
advection cutting snow ratios down, the Juneau area is looking at
much lower snow totals. That being said, looking on satellite, a
frontogenesis band looks to have set up north past Auke Bay in
Juneau over to Gustavus, which is expecting to stay somewhat
stationary for the next few hours. Therefore, these areas are
expected to be most inline for heaviest snowfall, with rates well
over one inch per hour. For down south, heavier rain rates are on
our doorstep, with PW over 200% set to stream in in the following
hours.

&&

.AVIATION...For the 06Z TAF update we have increased visibility
and ceilings in the southern and coastal areas (Sitka, Ketchikan,
Klawock, Wrangell) to MVFR prevailing through the rest of tonight
into tomorrow given the warm advection off the surface has
overtaken the snow production process, and mostly rain expected
there through tomorrow. Rain could be heavy at times during the
day tomorrow with short periods at IFR in the south. Further
north, the transition zone to a snow/rain mix has shifted north to
just south of Juneau. Higher resolution models are pointing to
increased southeasterly to eventually southwesterly flow (and
warmer air in the snow growth zones through 700 mb), and that
will start to shut off the heavy snow process for Juneau through
morning as we start to see a transition to a snow rain mix and
eventually to all rain by late afternoon. For the Icy Strait
corridor to Haines, a zone of heavier snowfall is being observed
in the satellite data, and this is occurring closer to the Arctic
front where the heavier forcing for snow, lower visibilities and
lower ceilings are being seen from Elfin Cove, to Gustavus,
northern Admiralty Island and north to Haines. Haines is where the
lowest ceilings and visibilities will prevail through morning and
where the heavier snow rates will continue to be seen at IFR/LIFR
through at least 20Z. Skagway will eventually trend down prevailing
more towards IFR as well through late morning.

&&

.PREV DISCUSSION...ISSUED AT 415 PM AKST Sat Dec 27 2025

SHORT TERM...Moderate to heavy snow continues to fall across most of the
panhandle. Temperatures have been slowly warming with the
precipitation coming down. Most places remain below freezing but
some of the outer coastal locations like Sitka have started to warm
above freezing and seen a transition from snow to rain. This warm up
is expected to work into the Inner Channels still and bring a
transition from snow to rain. The central and southern panhandles
are still expected to switch to rain tonight through tomorrow. The
main question still remains the Icy Strait corridor. Depending on
how far north the warm air gets, Juneau could still make the
transition to full rain or potentially see freezing rain mix in.
With the uncertainty, elected to keep the current forecast going
with only some updates to precipitation amounts, especially for the
southern panhandle. Precipitation is expected to continue through
Monday as onshore flow continues with a low remaining in the Gulf
of Alaska.

LONG TERM.../Tuesday through Wednesday Night/...The overall
message is that this timeframe will be the downhill slope in terms
of receiving heavy precipitation, with precip becoming lighter as
we progress through the period. Generally, in the mid levels of
the atmosphere the long wave trough will be closing off to a more
simplified closed low pattern over the central gulf by midweek.
Meanwhile, the surface feature goes from an extend low/trough
pattern to a single low, as well, & becomes more vertically
stacked & weaken.

The biggest challenge we are still working on honing in on is
that the warming may not end up reaching a stopping point as far
northward. The gradient indicating the location of the arctic
frontal boundary looks to stay in the southern Lynn Canal / Icy
Strait Corridor area appear & would keep the cooler air filtered
south into the Juneau area & would also keep Juneau in a rain /
snow mix or snow setup.

The atmospheric river continues to slide southward away from the
southern panhandle through Tuesday. We may have a few remaining
minor flooding issues, still, as the precip continues to taper
down. As the main flow pattern shifts southward, temperatures will
slowly cool down a bit, again, & push chances for a wintry mix of
precipitation back down toward the central & southern panhandle
again by Wednesday. With the surface low still sitting in the
central gulf into midweek with atmospheric waves rotating around
it, onshore flow will continue, & chance-level PoPs into the
Wednesday night remain likely.

AVIATION.../Until 00Z Monday/...A potent frontal system
continues its push into Southeast Alaska through the period,
bringing a mixed-bag of weather to the region. For the northern
panhandle TAFs, conditions primarily in the IFR/LIFR range
continue through the end of the TAF period as these areas continue
to receive significant snowfall. Southern panhandle TAFs will
continue the process of changing over to rain through the evening
& into the overnight hours as a warm front gradually pushes
northward. Central & southern Outer Coast areas like PAKW & PASI
are seeing this changeover first as those locations are currently
either already mixing or have fully changed over to rain. PAKT in
the southern panhandle will be next, then the central panhandle.
When the full changeover to liquid occurs, these central &
southern panhandle & Outer Coast areas will experience improving
conditions approaching & moving into the MVFR category. Winds will
generally be gusty out of a generally easterly or southeasterly
direction for most places. The exception will be the Lynn Canal
area TAFS(PAGY & PAHN), which will maintain a northerly direction
through the period. LLWS magnitudes peaking out at up to around 45
kt, between 150 & 200 degrees in direction, & centered aloft
between 1 & 2 kft are in store through the 24-hour TAF period as
the frontal system continues moving through.

MARINE...
Outside (Gulf/Coastal Waters): As of 3pm Saturday a southeasterly
storm force front is moving ashore into the inner channels,
weakening to gale force. Upstream, SW winds are becoming dominant,
with strong breeze to near-gale force strength. Southeast seas
reached peak intensity along the northern coast of 20 to 25 ft
this afternoon, and are expected to slowly subside to 12 to 18 ft
Sunday, with the dominant energy out of the southwest; highest
seas aimed at Prince of Wales coast. Several gale force systems
will rotate around the parent storm over the next few days,
freshening up winds along the northern coast to gale force at
times.

Inside (Inner Channels): For Saturday evening a frontal passage
will be the primary threat, with winds reaching peak intensity of
gale force into Saturday evening with gusts to strong-gales,
potentially storm force in Clarence. While Stephens Passage and
Clarence Strait hold on to gale force conditions Sunday morning,
most areas will start to reach fresh to strong breezes. Lynn Canal
continues to see northerly winds of fresh to strong breezes,
building to gales by Monday.

HYDROLOGY...A rain on snow event is ongoing for the area
starting lasting into Sunday starting for the southern panhandle.
Temperatures will continue to warm into the mid 40s to low 50s
through the southern panhandle as well as snow levels increasing
to around 5,000 to 7,000 ft. Farther north, the temperatures for
the central panhandle and Icy Strait corridor warm up to the mid
30s to upper 30s while snow levels warm up to 2,000 to 4,000 ft
during this time as well. Most of this warming is expected to
occur during the day Sunday, continuing into early Monday for the
southern panhandle. 24 hour rainfall amounts on Monday are
expected to reach up to 3-5" during the day for the southern
panhandle, while in the central panhandle, 24 hour totals are
closer to 2-3.5" of rain. Most of the heaviest rain rates are
expected this evening through early Monday morning. We have
issued a flood watch for Sunday and Monday from Sitka eastward to
Petersburg and south to Dixon Entrance due to the significant snow
amounts on the ground, what is expected to fall on Saturday, and
the heavy rain and snow melt.
