southeast alaska forecast discussion
national weather service juneau ak
250 pm akdt Mon may 29 2017

Short term Upper level flow remains onshore tonight into
Tuesday, which will keep the region overall mostly cloudy. However
there have been large breaks over the inner channels this
afternoon based on visible satellite imagery. Think that most
locations will see an increasing trend to the clouds tonight.

Tuesday afternoon into Wednesday an upper level low approaching
from the south will turn flow more offshore. This will help to
decrease clouds over the northern panhandle through the afternoon
and evening, but will likely see them increase across the south.

Models are showing some energy assoc wrapping around the low and
some moisture as well. Therefore have increased the potential for
some showers in the forecast Tuesday night, spreading north on
Wednesday. A surface low approaching from the south will also help
to increase rainfall potential over the southern panhandle
through Wednesday night.

Models came into better agreement on the new low to our south on
wed which increased pops. Preferred the GFS for updates to this
forecast package.

Long term Wednesday through Monday as of 10 pm Sunday night
upper ridge will remain east of the area with upper low trof
sliding east into the northeast pacific through midweek, then will
likely be weakening and curving into the gulf. The later time
frame operational models of ECMWF gfs are showing differences
regarding trough low over the north pacific. The forecast
Wednesday to Thursday, the operational models have good agreement,
and are positioned just a little more east closer to the
southeast coast.

The surface low late Wednesday to Thursday will be lifting a band
of light rain into the southern panhandle with periods of rain
through the end of the week. General low pressure, will continue
to persist to the weekend over the gulf of alaska. So continued
chance to likely pops for the end of the week for the forecast.

With expected continued cloud cover over the panhandle, lowered a
few of the highs over the end of the week for southeast alaska.

Highs from the upper 50s to lower 60s.

Public... None.

Marine... Small craft advisory for pkz012.

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.
