southeast alaska forecast discussion
national weather service juneau ak
302 pm akdt Thu mar 21 2019

Short term Little progressive weather today between the high
pressure ridge anchored over british columbia and the yukon with a
large slow moving low in the far western gulf of alaska, with the
associated frontal band strung out over the central gulf of
alaska. A weak trough band of clouds is hanging on over the
northern panhandle will continue. Light rain to sprinkles have
been reported for the northern gulf.

The strung out band will lift north and will likely try and spread
some rain and showers into the southern and then central Saturday
and Saturday night, at the the moment have not bumped the pops
for the southern.

Small craft marine winds for the outer coastal with a some
lingering gales for the norther gulf waters. Lighter winds over
the inside waters through the weekend. Forecast confidence is
average through the weekend.

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.

Small craft advisory for pkz022-035-036-041-042.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
