southeast alaska forecast discussion
national weather service juneau ak
233 pm akst Tue jan 16 2018

Short term A low is tracking across the central gulf and its
associated front will pass over the panhandle late tonight.

Another front coming up from the north pacific is on its heels and
will move into the southern panhandle Wednesday while the parent
low stalls southwest of haida gwaii. A short dry period should
exist between these two weather fronts Wednesday. Temperatures
continue to cool off, but stay mild through mid week.

The GFS and NAM were the preferred models. Previous updates remain
on track and no significant changes were observed in the new
models, so no significant changes made to the existing forecast.

Minor edits and updates made to areas of precipitation and on
temperatures.

Gales force winds over the eastern gulf verified by at least one
ship observation earlier today and cman buoys located in the gulf.

Gales will subside from south to north through the night with no
significant shift in wind directions. Easterly winds over the
southeastern gulf will ramp back up again to gale force tomorrow
along the northern periphery of the low approaching from the
southwest. Pressure gradient between the panhandle and western
british columbia remains tight, so small craft winds over the
eastern inner channels were included for tomorrow in the
afternoon forecast update.

Long term Thursday through Tuesday as of 10 pm Monday
complicated flow pattern looks to be developing in the long range.

Higher latitudes will be transitioning to a blocky pattern with a
ridge over the bering sea, a trof over mainland ak, and another
weak ridge over NW canada by late week. Mid latitudes will be
somewhat progressive with many shortwaves passing E across the pac
toward the pac NW states. The interaction between the northern and
southern streams will be the tricky part of the forecast. Some
models suggest phasing of streams over the epac gulf of ak area
for late weekend and early next week, with other models keeping
streams separate.

Main adjustment for thu-fri was to shift a low that moves toward
the haida gwaii area in short range further S and to decrease
pops. Also, a cooling trend looks likely for much of the long term
period, but there are some model differences on how cold it will
get. Temps were tweaked down some based on trends. Did make some
wind tweaks through 00z Sun to show more low level ridging over
the gulf. Overall, due to the complicated flow pattern developing,
forecast confidence is well below average.

Aviation Some areas of wind shear still exist, but conditions
in terms of wind and CIGS are slowly improving. Wind shear becomes
an issue again Wednesday afternoon as a low level jet to 60 kt out
of the southeast associated with the approaching haida gwaii low
moves over the southern panhandle.

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.
