southeast alaska forecast discussion
national weather service juneau ak
430 am akdt Sun may 20 2018

Short term through Monday night a weak occluded front will
move N through the eastern gulf today. A stronger occluded front
will move NE into the eastern gulf tonight, then move onshore se
ak by Mon afternoon. Models were slowing both fronts about 3 hours
from the previous forecast, so mainly time shifted the grids to
reflect the slower trend. Did make some other adjustments as well.

A band of rain is moving N through the area early this morning,
associated with a shortwave trof moving N ahead of the first
front. There may be a few hour break before more precip moves in
with the first front later this morning and afternoon. There is
also a short duration burst of wind with the shortwave, with 15-20
kt winds over the N channels attm. This wind should drop off some
early this morning, but winds will increase again during the late
morning and afternoon ahead of the first front. The gulf will see
winds reach SCA levels by early afternoon, and these stronger
winds should get into the clarence strait and cross sound areas
tonight.

With the second front, a more widespread and heavier rain is
expected. The moist plume with it has fairly decent vapor
transport (300-450 kg ms) with it. This will lead to locally heavy
rainfall later tonight into Mon across much of the area, with 1 to
2+ inches likely by Mon evening. Heaviest rain should fall near
and along south facing slopes. Should see decent rises on area
rivers and streams, but do not expect any flooding as water
levels are fairly low to start. Winds will pick up to gale force
over the gulf tonight, and more of the inner channels will
increase to SCA levels Mon morning as front gets closer to the
coast.

After this front moves through, precip should transition to
showers. Winds will drop off as well, but still expect SCA level
winds over the gulf Mon night as weakening second wrap of the
front moves in.

Long term Tuesday through Sunday as of 10 pm Saturday
continued outlook of a wet and cool pattern through next week.

Aloft an upper trough will remain over the gulf before lifting
out Thursday morning. Meanwhile the surface low in the western
gulf will weaken until it eventually gets overtaken by the next
front later in the week.

Overall models tend to remain fairly consistent with the idea
that skies will remain cloudy with widespread precipitation across
the panhandle Tuesday. Winds will diminish Tuesday afternoon
becoming fairly light by Wednesday morning. Used gfs ECMWF to make
minimal changes to the forecast Tuesday and wpc solution through
the weekend. High temperatures expected to remain in the low to
mid 50s through mid-week.

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.
