southeast alaska forecast discussion
national weather service juneau ak
611 am akdt Thu mar 21 2019

Short term through Fri night a relatively quiet morning with
little in the way of significant winds or precip. There is a
weakening front that has been producing light rain all night in a
band from sitka northward to haines, but amounts have only reached
a few hundredths per hour at most.

For the next 48 hours, generally quiet conditions are the norm in
the panhandle. The weakening front will remain mostly in place and
continue to weaken through Thu night bringing chance to likely
possibility of precip for the northern inner channels and NE gulf
coast. Snow levels remain around 4000 feet across the panhandle so
even areas as high as white pass will see mostly rain.

The next system is churning away in the SW gulf right now with a
front extending through the central gulf. Indications right now
are suggesting that how far east that front gets will largely
depend on a ridge of high pressure over western canada. That ridge
is expected to build west over the panhandle Thu night, and while
this push west will not be very substantial it will likely be
enough to keep the front (and consequently the precip associated
with it) offshore. Some showers may still linger around the
panhandle from the first front but for the most part expect a more
or less dry forecast for most areas through Fri night.

Likewise, the highest winds associated with the front will also
remain offshore through the period. Expect widespread 25 to 30 kt
winds with the possibility of gales near CAPE suckling
especially Thu night. Otherwise winds remain fairly light across
the inner channels except for the southern panhandle Thu night
where 15 to 25 kt SE winds will likely kick up with a very minor
short wave.

Overall changes minor. Used more NAM early on for its better
depiction of the precip over the area. Then used NAM and GFS for
the rest of the short range.

Long term Saturday through Thursday night as of 10 pm
Wednesday ... Extended range forecast will begin with a large
upper low situated just south of kodiak and west of vancouver
island. An upper ridge will extend from south central canada
northwest across british columbia, the yukon, and the alaska
interior. An upper trough located in the southeast quadrant of
the upper low will have begun to rotate north, causing the jet to
re-orient and shift north over the panhandle while weakening
through Saturday afternoon. The original upper low will drop
south through Monday and allow a large upper ridge to build in
over the gulf from the west. With another upper low over the
bering sea, this ridge may form an omega block on Monday night.

However, current models are still depicting the ridge as pinching
off a closed high which then moves off to the northeast. Gfs
maintains this feature farther south than ECMWF and the canadian
nh even farther south. Continuity in the ECMWF is considered best,
as the GFS was rotating this upper high out into the central gulf
by late Wednesday night in previous model runs.

At the surface, a low over the western gulf on Friday morning will
have tracked northwest in the bering sea by the start of this long
range period, Saturday morning. The associated occluded front
will have become quite ragged by that time. Precip should be
confined to the immediate outer coast. As the upper jet re-orients
and shifts north, a wave on the occluded frontal boundary and
possibly even a closed surface low that will re-orient the front
to a more east-west direction and move it north over the
panhandle on Saturday. Model agreement on this continues to be
average to above average. At this point, precipitation is looking
like it will end Saturday afternoon evening from south to north,
leaving only the northeast gulf coast in rain through Sunday
morning. The majority of southeast alaska should see a dry Sunday
with dry conditions likely lasting into mid-week next week.

No significant changes to most forecast elements. Did diminish pop
for Sunday onward based on latest wpc. Expected low level offshore
flow should result in partial clearing of the skies from the
second half of the weekend into next week. Thus, have increased
daytime highs and decreased overnight lows for the second half of
the long range forecast period. Overall forecast confidence is
average.
