Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
418 PM AKST Thu Dec 1 2016

.SHORT TERM...A storm force low will move NE into the eastern
gulf tonight, then move onshore near Cape Fairweather by early Fri
evening. Associated occluded front will move NE across the area
tonight and Fri morning, with second wrap of front affecting the
outer coast late Fri morning and afternoon. Used blend of the 12z
GFS and GEM, which took low track a little further W and
strengthened it some.

Big concerns will be winds and snowfall. The low level jet ahead
of the front reaches 75-85 KT at 850 mb, which will be enough for
gusts to 55+ KT over many land areas ahead of the front. Kept the
high wind warnings going for zones 23, 27 and 28. Added in zones
25 and 26 to warning area. Zone 23 will also get hit by second
wrap of front beginning late Fri morning, which will bring another
round of high wind to them. See NPW statement for valid times.
Have strong wind headlines for zones 21, 22, and 24 as well. These
areas will get strong winds with both the initial front and second
wrap. Will have storms for entire gulf area and over Clarence
Strait/Cross Sound with initial front tonight, then most of the E
gulf will have second round of storm force winds as second wrap of
front moves in Fri. Expect high end gales for much of the
remaining central and southern channels tonight and Fri, both from
the initial front and second wrap. Far N channels should reach SCA
levels at most during tonight and Fri.

Most places will get rain from this system, but the far N and
Hyder areas will see snow. Think heavy snow is likely for the
Haines highway west of the Chilkat River bridge and the Klondike
highway near White Pass. Kept the winter storm warnings going for
these areas, although did shorten the zone 19 warning until Noon
Fri with precip decreasing in the afternoon. Snowfall will be 9 to
14 inches in the zone 19 warning area and 12 to 18 inches in the
zone 18 warning area. Haines and Skagway will probably only see 1
to 3 inches of snow...mainly due to warmer temps and some rain
mixing in especially near Haines. Hyder could see 3 to 5 inches of
snow by late Friday morning.

Otherwise, temps will generally remain fairly steady or rise
slowly over much of the area, with the far N having better chance
to cool off tonight as low level flow shifts to northerly. There
could be a few TSTMS Fri afternoon over the S gulf but confidence
was not high enough to include at this time. Seas will get
extremely high especially near second wrap of front, with 34 to
38 feet likely over the SE gulf Fri.

.LONG TERM...The storm force low will have partially moved
inland by Friday night. Strong southwesterlies winds will slowly
fall overnight, but most who venture outside will begin to notice
a distinct chill in the air. Atmospheric thicknesses and snow
levels will begin falling Friday night with snow making an
appearance over most of the Panhandle on Saturday. Onshore flow
with the possibility of a convergence zone setting up ahead of the
the flank of cold air moving south will likely yield 1 to 3 inches
of snow across portions of the northern and central Panhandle for
Saturday into Saturday night. Friday night we raised Lynn Canal to
30 kt southerlies and there lies the possibility of very windy
conditions for Skagway Friday night. Quickly though as the
pressure gradient relaxes Saturday, higher pressure will build to
our north allowing a surge of colder air and drier air to
infiltrate the Panhandle from the north. Winds will then turn
northerly Saturday night in a big way. With such cold air, our
confidence in strong northerlies for Skagway and Haines are
bolstered. We have even placed freezing spray in many of the
northern and north-central Inner Channels into early next week.

We expect the frigid air mass and associated clearing to lower
temperatures to levels we have not seen in quite a while with
highs nearing 20 and lows approaching 10 for the areas of the
central Panhandle and subfreezing temperatures all the way south
across Southeast. Haines and Skagway could dip to near zero. This
cold and dry pattern looks benign except for the northerly outflow
winds through Haines and Skagway and some northern Inner Channels.
Eventually though, we feel that some system will interrupt it by
infusing our atmosphere with overrunning moisture from the south.
The ECMWF is more bullish on these prospects...spreading snow into
the Panhandle as early as Wednesday. The GFS though keeps things
cold and dry. However, the late 18Z GFS run now is following the
ECMWF's hints of an overrunning event Wednesday/Wednesday night.
At this point, we made very little changes in the extended period
with a chance of snow and continued cold from mid-week onward.

GFS/ECMWF was used Friday night into Saturday night with some new
WPC employed mid-next week. Forecast confidence good.
