Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
541 AM AKDT Sun Apr 2 2017

.SHORT TERM...Issued at 520 am Sunday. /through Tuesday night/ An
upper level short wave associated with a weakening low over the
northwest gulf moved over the panhandle overnight and has since
entered Canada. This short wave produced widespread shower
activity overnight but has diminished somewhat in the early
morning hours. A slightly cooler low level airmass has also
advected in from the west, resulting in periods of snow showers
instead of rain showers. Freezing rain was also reported for a
short while over the far southwestern panhandle around 3 am.
Forecast high temperatures today should see shower activity today
transitioning to unmixed rain everywhere except the higher
elevations of the Klondike Highway. Another short wave associated
with a mid level disturbance is forecast to cross the gulf from
southwest to northeast today and enhance showers tonight.
Marginally less in the way of frozen precip is expected tonight as
low level warm air advection from the west should result in a
fairly flat or even reversed diurnal temperature curve,
particularly along the central and southern outer coast. Locations
more inland will see overnight lows occurring by midnight with
little change afterwards until Monday morning.

This modest warm up on Monday will precede a marginal storm force
front that will arrive along the southern outer coast late Monday
afternoon or Monday evening. Hot on the heels of this front, a
second will arrive from the southwest and overrun the first late
Tuesday. Both of these fronts are being depicted by models as
having a significant amount of precipitable water and 72 hour
totals of as much as 2 inches are currently forecast. Warmer low
level temps will result in the vast majority of this precipitation
to fall as rain. Exceptions, as before, will be the higher
elevations of the Klondike and, possibly near the border on the
Haines Highway.

Marine winds become decidedly more severe beginning beginning
Monday morning with southeasterly 45 kt gales arriving over the
coastal marine zones by Monday afternoon. At this time, think the
storm force winds may remain well off shore over zone 310. As the
first front weakens Tuesday morning, the second front will arrive
Tuesday afternoon and result in another round of 45 kt gales over
the coastal marine zones Tuesday night.

.LONG TERM.../ Wednesday through Sunday / Rather strong upper low
anchored over the western gulf does not show many signs of moving
on mid week as a strong jet on its southern flank reinforces its
presence. Extended guidance is rather certain on this with just
about every model getting on board. However by late week into the
weekend the southern jet gets pushed southward by various waves
moving east across the northern pacific cutting off the main
source of upper dynamics for the western gulf low. What happens
after that is up in the air as several scenarios are suggested.
However, most paint that at least a weak trough will remain in the
western gulf through the weekend with noticeably reduced upper
level flow over the panhandle and a Pacific storm track aimed more
at the Pacific NW rather then Alaska.

Main trend for the long range for the forecast over the panhandle
is rather wet and windy weather mid week giving way to drier
conditions by the weekend. Incoming gale force front for Tue into
Tue night will bring another round of rain and wind for many areas
of the panhandle. Forecast mainly on track with this system. Gale
force winds possible for many marine areas and with 850 mb winds
approaching 50 to 60 kt strong wind gusts are possible for the
southern panhandle and outer coast as well.

By Friday into the weekend the main Pacific storm track shifts
southward sending most of the storms into Vancouver Island or the
Pacific NW. The main trend is toward an inverted trough at lower
levels setting up over the area by the weekend. The resulting
offshore flow means drier weather and the possibility of more
breaks in the cloud cover. I can not completely rule out any
precip however as some models are still bringing some short wave
energy into at least the southern panhandle Sun into Mon so a
chance of rain for the southern half of the panhandle still
persists.

&&

.AVIATION...Persistent low over the W gulf will push a weak
surface trough into the panhandle this morning. Expect some mixed
precip this morning to result in MVMC as the boundary pushes
across the region. Precip will diminish slightly as boundary
pushes inland, but persistent onshore flow will maintain showers
most of the day. Another surface trough propagating from the low
in the W gulf will impact mainly the central panhandle this
evening/overnight with another period of low MVMC through early
Mon.

&&

.AJK Watches/Warnings/Advisories...
PUBLIC...Strong Wind through this evening for AKZ018.
MARINE...Small Craft Advisory for PKZ012-013-022-041-052.
     Small Craft Advisory due to Seas for PKZ042-043-051-053.
