Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
435 AM AKST Wed Mar 1 2023

.SHORT TERM...Made minimal changes to the Wednesday forecast with
a Warning in place for snowfall and the approaching frontal band.
The snow increased its intensity from the late evening to the
early morning hours. Based on visibilities, a satellite estimates
top rates are 0.5 to just over 1.0 inches an hour. The front
appears to be tracking close to what was expected through tonight.
The biggest change that was made to the forecast was a slight
adjustment to winds over the gulf and panhandle for the late
afternoon tonight. The Central Gulf storm force winds were bumped
up to 55 kt and the panhandle got a boost as well to sustained and
gust, mainly due to the westerly push reaching the area.

.LONG TERM.../Wednesday Night through Sunday/ A rapidly developing
low in the Gulf of Alaska is expected impact the region with the
heaviest snow accumulation expected Wednesday morning and through
the afternoon. Gale force winds will accompany the front
extending from this feature as it impacts the panhandle early
Wednesday with some areas experiencing storm force winds along the
outer coast as the front approaches. Winds in the inner channels
will also increase to upwards of 25 knots before subsiding through
Thursday night. Winds in the gulf are expected to reach storm
force Wednesday night before beginning to slacken as the low
stalls and progressively weakens over the northern gulf.
By Wednesday night, the heaviest of precipitation is expected to
be over with mostly trailing showers and persistent onshore flow
as the low remains in the northern gulf. Thursday and Friday, most
of the panhandle is expected to see continuing diminishing
showers, shifting to all snow for the southern half of the
panhandle as temperatures continue to drop heading into the
weekend.

Both deterministic and model guidance continue to suggest the low
departing the gulf to the south on Friday, with high pressure
building over the Yukon Territory. Thus the panhandle will once
again be shifting into a northerly outflow pattern with winds in
Lynn Canal reaching gale force Friday night into Saturday. The
gradient associated with this high pressure may shift to be
oriented more East/West, thus leading to winds in the northern
inner channels slackening early next week, but still maintaining
overall outflow.

&&

.AVIATION...A poor day for flight as IFR to LIFR conditions with
strong SE LLWS last through the day as the current frontal
boundary moves over the AK Panhandle. Weather will improve
slightly by the evening as the front moves SE, precip rates
decrease, and snow begins to mix with rain resulting in improved
visibility. LLWS shifts to the SW this evening as secondary wrap
moves in with another stronger burst of winds. Showers will last
for next 48 hours with conditions becoming more variable by
Thursday.

&&

.MARINE...Storm force frontal band along the outer coast Wednesday
morning. Behind the front, A Strong area of 50 to 55 kt winds move
across the gulf to move to the central and southern panhandle
coast Wednesday evening and night. The combined seas created the
westerly band will be into the lower to mid 30 ft range. The storm
surge is expected to be largest in the evening time frame while
raising the water levels occurring around a low tide time frame.
However, coastal areas should be prepared for large seas (25+ ft)
to be breaking on the coasts, and any moorings or harbors should
be prepared for the situation.
