Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
631 AM AKST Sat Jan 16 2021
.SHORT TERM.../Through Sunday night/...This short term forecast
will be more of the same that southeast Alaska has seen for
several days now with only minor plot twists. Namely, the current
front in the gulf will be storm force strength vice gale force,
and there are currently no winter weather advisories or warnings
for the far northern inner channels.
The storm force front will remain far enough off the coast that
only strong wind gusts (40 to 45 mph) are expected for the central
and southern outer coast, Kuiu island, and the downtown Juneau
area. Over the eastern gulf, the storm force winds will be gone by
this afternoon, being replaced by southwesterly small craft winds
late tonight. By late Sunday night, the next storm force front
will be entering the eastern gulf from the west.
Warm low level air resulting from a seemingly never ending series
of fronts and deep layer onshore flow will continue to produce
rain. There is some snow in the forecast for the far northern
inner channels, but not enough to warrant another round of weather
advisories. Even though the intensity of the current front will
diminish steadily beginning this afternoon, frontal precipitation
is expected to stall over the northeast gulf coast and Panhandle.
Don't expect a break in the rain until possibly Sunday afternoon.
Sunday night looks like it will be less wet, but any break will be
soon overcome by the precip associated with storm force front
number two that will enter the eastern gulf late Sunday night.

.LONG TERM.../Monday through Saturday as of 10 pm Friday/ Pattern
change in the works as we head through next week. Initially we
will still be stuck in an active SW flow pattern aloft with at
least one more storm system moving through the area in the first
part of the long range. That gradually changes mid week into late
week as more ridging begins to show up over most of the Gulf of
Alaska and Central Alaska. However, this ridging is not strong
enough to be a blocking pattern as at least one storm will be
trying to push through the ridge and into the panhandle next
weekend. Depiction of the SW flow and the initial ridge mid next
week has fairly average forecast confidence, but that confidence
falls to low toward late week and next weekend as long range
guidance has trouble figuring out how strong system trying to
break through the ridge will play out and if it will make the
panhandle or not.
At the surface, the first part of the long range remains fairly
active with a wet storm-force front moving through the area Mon
into Mon night. IVT and PW anomalies continue to indicate a
fairly decent atmospheric river connection with this front.
Fortunately, the front does not linger over the area very long so
we are looking at around 1 to 3 inches of QPF over any given area
through Mon night right now. Still there will be periods of
moderate to even heavy rain at times for most of the panhandle.
Most areas will be warm enough for rain, but the Haines and
Klondike highways may see some snow (possibly several inches worth
near White Pass). Winds will be the other concern, but with the
parent low so far W, the front will be weakening as it moves E.
Storm force winds are expected for the northern gulf while gales
(Marine areas) and gusty winds 40 to 55 mph (land areas) are
expected elsewhere.
The forecast quiets down for Tues onward as the ridging aloft
begins to develop. Some fairly weak system will still try to
advance on the panhandle through the period, but they do not have
the strength that previous systems have had. There is also more
forecast uncertainty showing up from Wed onward as guidance tries
to figure out what to do with the developing ridge. Overall trends
point toward a drier forecast with the possibility of some cold
air working southeastward Thu into Fri. The cold air is somewhat
uncertain as the Canadian is being rather aggressive with it
while the ECMWF is not as aggressive and the GFS is has it barely
there at all. We will continue to monitor how this pattern change
develops.
