southeast alaska forecast discussion
national weather service juneau ak
251 pm akdt Sat mar 23 2019

Short term through Monday southeast alaska is headed into a
period of more benign weather. A vertically stacked low south of
the gulf of alaska will rotate and drift east through Monday just
south of 50 north. A weak trough will spin out of this low
northward to the central gulf coast tonight and early Sunday,
spreading a little light rain to that area, it should stay west of
yakutat.

The high pressure ridge that builds over the panhandle and western
canada into Sunday will nudge west to the northern gulf as well
by Sunday night with small axis from the northern gulf-yukon-
northern british columbia. This will result in a general
northerly offshore like flow pattern. It won't be a true offshore
flow due to a high building across the gulf. Along the outer
coast a northwest flow pattern will develop through the first half
of Monday, most of the inner channel outflows would end up
exiting the panhandle south of the frederick sound.

Southeast alaska should see the rain stop early Sunday, except
near or west of yakutat where that will end by Monday. Slow
clearing on headed into Sunday for the panhandle. The northeast
gulf coast will start to see more Sun early Monday. With the
clearing and some moisture around early Sunday morning have added
some fog around petersburg, ketchikan and klawock and angoon.

Long term Monday through Friday as of 9pm Friday. On Monday,
weak variable flow at the jet stream level takes a turn out of
the north due to a high amplitude ridge building over the state.

At the surface, high pressure centered over the gulf will slowly
shift to the western gulf and an inverted trough will be over the
inner channels. The upper level and surface pattern support dry
weather and northerly winds.

Through Tuesday, the upper level ridge will continue to amplify,
extending up to the arctic then back down across the yukon and
finally across the SE alaska. It may bring slightly cooler air
with it, but nothing really notable. Models are bringing some
moisture along with the jet streak and a vorticity MAX wave. Some
models are developing this into a closed upper low and will need
to be monitored over the next few runs for more development. Most
of the moisture should stay on the eastern side of the coast mtns
but will certainly see some increased cloud cover. Expect winds to
pick up for a period tues night into Wed along with mountain wave
potential. As the vort upper level low tracks south, a weak
surface reflection (or the inverted trough already in place) may
develop once it hits the gulf waters, so pop has been increased
to chance over the southern inner channels. Behind this feature,
the flow shifts more NE as the upper level ridge tips over. This
will help to keep us dry with likely downslope warming for
Wednesday.

The upper level ridge closes off with the high pressure center
shifting south through Friday which will cause flow aloft to turn
onshore, although perhaps not for long. Models disagree on how
quickly the high pressure pushes off to the south. The surface
inverted trough looks to weaken, causing winds to become light and
variable, however some have it redevelop right away with no precip
in sight.

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.
