Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
301 PM AKST Sun Nov 28 2021

.SHORT TERM.../ Through Monday night / The weather for Sunday
into Sunday night is snow showers rolling off the Gulf of Alaska
and into SE AK. Continued winter weather advisory for the
northeast gulf coast and across much of the northern panhandle for
tonight.

A weak ridge of high pressure keeps the southern panhandle on the
dry side this evening, the high moves into British Columbia by
early Monday. An occluded weather front will move east-northeast
across gulf to the panhandle Monday afternoon starting to bring
precipitation into Southwest Panhandle. Snow or a mix switching to
rain for the southern panhandle and then more organized light snow
for the north central panhandle, with the potential to become a
mixed rain/snow for the Icy Strait corridor.

As the front approaches the outside waters bringing gale force
winds Monday afternoon and Monday night as a new wave starts to
move into the Southeastern gulf late Monday night.

.LONG TERM.../Tuesday through Friday as of 4 PM Sunday/ A mean
trough with an associated surface low pressure centers itself
over the Gulf through the long term period. Through the period
multiple lows spin up in the gulf bringing consecutive waves of
precipitation, some more impressive then others. Tuesday, a
strengthening low swings up into the SE gulf bringing with it a
high end gale force front (winds 35-45 kt). This low will lift N
through the day before dissipating over the central panhandle.
This system looks to have decent warm air advection associated
with it, leading to surface temperatures to warm above freezing
across most of the panhandle. Across the south precipitation will
be rain, but across the north precip is expected to start as snow
before changing to rain. Current thinking is that snow
accumulations between 2-4 inches are possible across the far
north with lesser amounts through the north central.

Wednesday turns to more of a shower pattern before yet another
wave enhancement moves through the southern panhandle. This
enhancements looks to bring more rain as temperatures will still
be above freezing. By Wednesday evening, strong cold air
advection moves into the panhandle from the gulf putting SEAK
under a snow shower pattern once again. This time, temperatures
across the entire panhandle could fall below freezing, letting
everyone play in the snow late Wednesday night into Thursday.

Towards the end of the week, confidence drops significantly has
models struggle to place a new low in the gulf. The GFS/CAN have a
drying trend in place for the weekend while the EC brings in a
storm across the NE gulf. One area where agreement is better, is
on cooling 850mb temperatures through the weekend. Today, MOS back
off on such extreme cold temperatures for the weekend so decided
to follow suit and nudge temps back up slightly.
