Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
237 PM AKDT Sun Aug 27 2017
.SHORT TERM.../ Through Tuesday / Rather active short range
forecast today as we deal with the remains of the current system
tonight followed by a gale force front Mon into Mon night. What
remains of the current system is bringing showers to the northern
half of the panhandle this evening which will gradually diminish
through the night as easterly flow ahead of the next front
increases. Still have a slight chance of thunderstorms up for the
northern gulf and gulf coast this evening as the last of some
cooler air aloft and some upper level dynamics moves through.
Focus then shifts to a new system coming out of the northern
Pacific for Mon into Tue. The main low center will stay well to
the west of the area taking up a position south of Kodiak Island
by late Mon night. The initial warm front however will be moving
through the area Mon into Mon night from north to south bringing
some winds and rain. Highest winds mainly confined to the gulf
waters with gale force pre-frontal winds developing in the
northern gulf due to barrier jet effects Mon afternoon. For the
inner channels, winds will be switching to the N for many marine
areas, before switching back to the south post front. As for
rain, indications right now point to most of the rain staying west
of Kake and Stephens Passage through some light rain east of that
line is not out of the question. Highest amounts are expected
from Yakutat westward as an atmospheric river pumps tropical
moisture from near Hawaii into the northern gulf coast through
Tues night.
Behind the warm front the rest of the panhandle drys out as the
main cold front remains out in the gulf through Tue. As a result
the panhandle is looking at a period of warmer temperatures Tue
into Wed as indicated by rather high thickness values over the
area and guidance predictions of temperatures 1 to 2 standard
deviations above normal in the warm sector of the storm. Ended up
raising temperatures a bit more over what the long term
forecaster did last evening for Tue (ended up with upper 60s for
most areas for highs Tue). It might also feel a little more humid
as well with dew point temperatures reaching into the mid to upper
50s during that time.
Guidance for the short term was rather good with not much model
disagreement on display today. Used mainly GFS and NAM for
guidance today.
.LONG TERM...Tuesday through Sunday...As of 900PM Sat...Little
change to forecast reasoning through the extended. Period begins
with an upper low over the W gulf with surface low moving N
towards Kodiak. Models in fairly good agreement on the track, but
differ some on the strength with central pressures ranging from
low 970s to low 980s Tue afternoon. This pattern favors precip
along the N gulf coast with persistent WAA across the rest of the
panhandle. Ensembles continue to indicate temps 1-2 standard dev
above normal Tue into Wed so nudged temps up a couple of degrees
Tue. As the low moves into the W gulf, SCA likely will develop
over the gulf with marginal gales over the offshore waters and
possible along the N gulf coast as barrier jet develops ahead of
the approaching low. Overall upper level pattern remains onshore
(W-SW) through the extended so maintained increased PoPs for the
latter half of the week to account for quickly moving mid level
impulses tracking across the region in the active flow pattern.
Forecast confidence about average early, but given the large
spread in ensembles and operational runs, it drops to below
average for the latter half of the week.
