Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
247 PM AKST Thu Dec 6 2018
.SYNOPSIS...The shift into a wet, windy, and active, but still
seasonably warm weather pattern will occur over the next day. This
new weather regime will persist through next week.
&&
.SHORT TERM...A return to an active weather pattern will occur
over the next 24 hours. Current satellite imagery shows a surface
low pressure system just south of Kodiak, as well as a large area
of energy over the northern Pacific. This energy will organize
into a surface low pressure system over the next day and push
northward across the gulf of Alaska. A band of storm force winds
will accompany this low as it tracks north over the gulf.
Additionally, seas will build to 20 to 30 feet over the vast
majority of the gulf by Friday night. For land areas and the inner
channels, expect the strongest winds to be along the outer coast
as the low tracks north and for the East-West orientated channels
specifically Sumner Strait and Cross Sound. While some strong
gusts are possible out of the system along the coast, high winds
are not expected due to low level atmospheric stability acting to
keep the strongest low level jet winds from mixing down to the
surface. That being said, if the low takes on a slightly more
easterly track, Yakutat could see a very brief southerly high
wind on the back side of the system early Saturday morning. As far
as precipitation impacts, the biggest area of concern will be the
Haines and Klondike Highways where precipitation looks to fall as
snow, but with the front significantly weakening by the time it
reaches these locations, significant accumulations are not
expected.
This active pattern continues into Saturday as another strong low
pressure system tracks north over the gulf. While the surface low
center takes a more westerly track than the Friday system, strong
gale and some storm force winds are expected again over the
eastern gulf waters. Precipitation will be more impactful out of
this storm as well, with periods of heavy rain expected for much
of the Panhandle Saturday. Along the Haines and Klondike Highways
some significant snowfall is possible; however, with lower
confidence in the ultimate timing and track of this storm, no
watches are currently in effect.
Overall little to no changes were made regarding the Friday low.
The intensity of Saturday's low was increased to bring strong
gales and some storm force winds into the forecast; however,
confidence is lower for Saturday's storm as a fair amount of
spread still exists. The 12 GFS was favored to adjust Saturday as
needed; however, this portion of the forecast could still see some
refining by future shifts.
.LONG TERM.../Saturday through Wednesday/Upper trough will be
deepening and taking on a negative tilt over the Gulf by Saturday.
Low level frontal zone will remain draped over the Panhandle or
perhaps just offshore in the eastern Gulf into Sunday. Models are
struggling greatly with timing and strength of individual pieces
of energy ejecting out of the base of the trough towards SE AK on
Saturday into Sunday. Diffluent upper jet will provide ample upper
support to tighten the low level front late Saturday into Sunday,
as evidenced by the presence of 70-80kt at 850 mb in many of the
models along the frontal zone. This could lead to strong gales or
storm conditions over the eastern Gulf with the potential for high
wind gusts for parts of the coastal and southern Panhandle at some
point late in the weekend. Still too much uncertainty to pin down
strength and location, so later shifts will need to monitor.
Heavy precipitation will likely occur as well Saturday into Sunday,
again dependent on the exact track and strength of any surface
waves. Thermal profiles along the Haines and Klondike highways
initially will support snow, with the potential for enough warming
to change the Haines road over to rain by Saturday night. Should
the precipitation remain all snow, significant accumulations will
be possible for the higher elevations of the highways through
Sunday. Elsewhere, only rain is expected near sea level.
For early to mid next week, most ensemble guidance continues to
call for a very strong and active zonal Pacific jet to develop and
nose into the western Gulf. This will set the stage for yet
another significant storm to enter the Gulf by late
Monday/Tuesday, bringing another round of heavy precipitation and
strong winds. Temperatures begin to cool by mid week as modified
arctic air begins to drawn into the Gulf from the Bering Sea,
however no significant snowfall near sea level is expected through
mid week at this time.
&&
.AVIATION...Biggest aviation concern will be the threat of
significant low level wind shear beginning late tomorrow morning
for the southern Panhandle and tracking north with the low through
the day evening and overnight hours. A significant low level jet
will develop northeast of the of the low center with around 50 to
60 kts of wind around 2000 ft. sliding northward along the
coastline.
