southeast alaska forecast discussion
national weather service juneau ak
550 am akdt Mon sep 25 2017

Short term Monday and Tuesday a few lingering showers
across the southern part of the panhandle Monday morning should
diminish through the day. Fewer clouds over the central and
northern panhandle has allowed fog to form over the saturated
terrain. This should be improving after sunrise with heating and
mixing.

A trough digging south in the long wave trough south of the cold
bay region is building up the ridge along west coast of north
america. Expect the ridge axis to the east of southeast alaska,
meaning that the panhandle will be in the wetter side. This will
also shift the flow to be more out of the north central pacific,
which is looking to carry a lot of mid tropic moisture northward
with the waves.

Expect the start of the next system to move into the southern half
of the panhandle Monday night into Tuesday morning. Think the
initial axis of the triple point should move onshore near sumner
strait, then the rain will move north through the panhandle
Tuesday. By Tuesday the evening the upper level flow is more
southerly across the eastern gulf of alaska and that will be
shifting stream of moisture northward towards the cross sound
area by late Tuesday night.

Long term Wed night through Mon still some important model
differences to work out for mid-late week system but threat for
heavy rain somewhere in the area remains on the high side. Precip
water values are running 2.5-3 standard deviations above average
in the GFS ec ensemble guidance for wed-thu. Jet axis aloft will
run N into the NE gulf coast area with speeds in the 100-110 kt
range. At this point, main forecast difficulty is where axis of
heaviest rain sets up, and this is mainly due to models handling
low pressure waves on the front differently. Ended up not making
any big changes to the forecast for Wed night-thu but did bump
winds up some over the area based on model trends.

Later in the period, looking like main cold front will cross the
area late Thu or Thu night. Did speed up transition over to
showers behind this front for Thu night and fri. Weekend looking
on the wet and cooler side with remnant of parent low moving e
across the gulf. Will need to watch for any potential systems
coming out of the southern stream into the area by late in the
weekend or early next week, but there are large model differences
on this.

Aviation Lower clouds and rain over the southern third of the
panhandle this morning will improve as the last of the showers
fade into the afternoon. Across the central and northern inner
channels the morning fog has started to make and appearance. This
should burn off in the morning resulting in a mid levelVFR
ceiling or near ceiling if it clears out. Do expect that the
southern panhandle will start to get more rain spreading in over
the evening hours from the southwest.

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.
