southeast alaska forecast discussion
national weather service juneau ak
556 am akdt Fri may 24 2019

Short term Weakening surface low continues to track east across
the northern gulf and looks to be dissipating as it reaches near
the coast of chichagof baranof islands. The tail end of the
Thursday surface trough finally moving through the remainder of
the southeast panhandle that will lift the lower clouds around but
will stay mostly clouds as there is still widespread clouds in
the gulf that is being pushed towards the coast. Expect lingering
scattered showers for southeast alaska then ending from the
northwest through the day.

A ridge building over the eastern gulf of alaska will keep the
upper level flow pointed north towards southwest alaska, and the
panhandle will be dry with some warming temperatures Saturday and
Sunday. Should see more Sun for the weekend and temperatures will
climb into the upper 60s to near 70 degrees or warmer for parts
of the panhandle. The model solutions are suggesting that the
ridge will slowly drift east into Monday as weather systems from
the western gulf spread east. Rain may get as far east as yakutat
by Monday, but model solutions are not that solid yet on some of
the individual waves moving north along the front for the central
gulf coast.

Local gusty winds near CAPE spencer and CAPE decision with
afternoon heating more so for Saturday and Sunday than for Friday,
as there will be better afternoon heating those days and likely a
light sea breezes for the communities in southeast.

Long term Sunday through Friday as of 10 pm Thursday
upper ridge will remain over and just east of the area into early
next week. After mon, they hint that the ridge will be nudged
slowly E as several shortwaves move N on its W side. Still a lot
of model differences on track of these shortwaves though, so
confidence in making any forecast changes after Mon was on the low
side, so pretty much left the forecast as is beyond then. Did use
an 18z GFS 12z ec blend to tweak pressures and winds for Sun into
early mon.

Did not change pops for the early part of the period due to some
differences in how far E the weakening occluded front would get.

Majority of the models would suggest slowing the eastward shift to
the pops however. Later shifts can change this if the model ideas
become more consistent with this front.

The upper ridge may weaken and drift far enough E by midweek to
better allow systems to move across the area. However, kept in
only chance pops for that time frame given significant model
timing track differences with those systems.

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.
