Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
301 PM AKST Mon Feb 1 2021
.SHORT TERM.../Monday and Tuesday/ A very complex and dynamic
winter storm continues to unfold across Southeast Alaska this
afternoon as a developing area of low pressure moves SE out of the
northern gulf. Heavy bands of snow continue to move through the
northern half of the Panhandle this evening as seen on satellite
and radar imagery. Lower resolution models struggle with
identifying mesoscale features and their evolution through time;
making forecasting bands of heavy snow very difficult more than a
few hours out. Guidance over the past few days has been indicating
a convergence zone setting up over the Central Panhandle where a
heavy snow band would likely develop; however lower confidence
existed on the exact location it would form. Guidance last night
trended the placement of this band further west and model runs
today continued that trend. What looked to be a Kake snow event
yesterday has turned into a Juneau to Angoon to Little Port Walter
snow storm as the narrow band of heavy snow has set up right over
this area. 12z RAOB soundings and recent MDCRS soundings indicate
a stable boundary layer with NE winds keeping cold air at the
surface with a very unstable layer above 850mb and into the DGZ.
Mid and upper level lapse rates exceeding 8.5C/km and a fully
saturated column indicate efficient snowflake production in the
DGZ, high snow to liquid ratios, and the possibility for
impressive snowfall rates of 1-2" per hour.
This morning, Yakutat received 8-10 inches of snow within a 10
hour period with only 0.25 inches of liquid, yielding snow ratios
upwards of 40:1! With the banded and showery nature of the snow,
snow accumulations will greatly vary from one town to the next.
Under the heavy snow band across the north central Panhandle,
expect an additional 3-6 inches through this evening with snowfall
rates exceeding 1" per hour. The Winter Weather Advisory for
Juneau and Angoon has been upgraded to a Winter Storm Warning as
total snow accumulations through tonight will be upwards of 4 to
9+ inches. Lower, sub advisory snow amounts expected around
Haines, Gustavus, Pelican, and across the southern half of the
Panhandle.
As the area of low pressure moves SE along the coast, expect
precipitation to pivot and sag southward along the Outer Coast.
Guidance has also trended a tad further west with the position of
the low, keeping the heaviest snow slightly offshore of POW
Island. Kept slight chance to chance wording for POW Island as a
few snow showers will still be possible through Tuesday morning.
A northerly outflow event begins as this system departs tonight
and into Tuesday. Storm force northerlies develop in Lynn Canal
with small crafts in the Central Inner Channels on Tuesday. Expect
gusty winds to 50 mph in Skagway during this time frame as well.
Mountain Wave guidance indicates marginal conditions for Taku Wind
development late tonight through Tuesday morning. Currently do
not expect a full Taku to develop; however with a strong northerly
gradient, gusts to 40-50 mph are still possible in Downtown
Juneau and Douglas. Along the Northeast Gulf coast, expect gale
force winds blowing out of interior passes.
Confidence is only around average for the short term as the main
challenge will continue to be pin pointing exactly where smaller
snow bands set up Monday evening.
.LONG TERM.../Wednesday through Monday night/...Extended forecast
period begins with a broad ridge to the south. Northwesterly flow
will be in place behind a low that has departed to the southeast
and will promptly be replaced by another low and associated
frontal system. A very tight pressure gradient through the
northern inner channels will be slackening at the beginning of the
forecast period as well. Overall, the region should be cold enough
for the predominant precip type at the onset for this Wednesday
system to be snow, however, flow will switch around to the south
and should see a transition to rain early for most coastal areas
and the southern inner channels. Through the inner channels, early
indications are that this warm push should be able to transition
precip over to liquid as far north as Hoonah before the end of the
day. Precip associated with this system should linger through
Thursday for many areas and by the end of day two, may see the
change over to rain reach Gustavus and Juneau. Snowfall totals
from this system look to be mostly unimpressive for southeast with
the exception being the interior location of Hyder which remains
cold enough for snow and gets the added benefit of the highest
precip totals being in the southern panhandle.
Any break that we get from precip should be short lived as the
pattern remains active with yet another front poised to impact the
region from the southwest Friday into Saturday. Noticeably warmer
air can be expected with this front. How far this can actually
drive the rain/snow line north is still up for a great amount of
scrutiny, but what is becoming increasingly evident is that Haines
and Skagway do not look likely to see much of that warm up and
with the amount of moisture that could be accompanying this front,
a decent snow event may be in the works.
For the duration of the forecast, a sizable break in
precipitation does not appear to be in the cards as the Fri/Sat
front is projected to trough out over the region before being
absorbed into yet another frontal system late in the period. By
this point, enough "warmer" air may have crept into the region,
and with persistent cloud cover, diurnals may not be in play which
could lead to less likelihood for snow for many areas, or the
alternative of temperatures fluctuating right around the freezing
mark. Still have plenty of time for future analysis regarding such
things, but for now, optimistically wishing for the warm up.
