southeast alaska forecast discussion
national weather service juneau ak
246 pm akdt Fri sep 20 2019

Short term Mimic indicated precipitable water traces a long
tentacle of subtropical moisture north-northeastward across the
north pacific squarely into southeast alaska. Precipitable water
and ivt values for the yakutat 12z sounding are not record worthy,
but still are very near during one of our wettest times of year.

With the previous systems priming us, and a few before that, we
have reached the point of concern with minor flooding for the
taiya river near skagway, montana creek in juneau, and the indian
river in sitka. Rainfall amounts of 1 to 2 more inches are
expected tonight with isolated amounts up to 3. Increasing
cyclonic curvature over the northern panhandle at 500 mb also led
us earlier to increase winds through the juneau area for gusts to
60 mph and for much of the rest of the panhandle of 40 to 50 mph.

Winds will slowly come down at juneau this evening but remain
strong over haines, skagway, and ketchikan through early Saturday
morning.

Rainfall will turn more showery by Saturday as more unstable air
migrates in. Weak ridging will occur across our CWA through most
of the weekend, but continued southwesterly flow in the low levels
will allow for showers to continue during this time period.

Showers may become more scattered in nature, but QPF amounts are
still relatively high, in general to account for short-duration
more intense rainfall. The next big system arrives Sunday night
into Monday. This will bring another round of very strong winds
and heavy rainfall for much of the panhandle.

No changes were made to the forecast so as to free staff to
monitor and react to the current dynamic system.

Long term Sunday through Friday as of 10 pm Thursday
the weather will be most active during the first half of the long
range period, then a quieter pattern is becoming more likely
during the latter part. A strong occluded front will move NE into
the area Sun night into mon. Looking like a significant low will
form and move nne into the gulf by Mon morning, then curve back
to the W and merge with the original parent low that will be
moving E into the gulf during mon. This combined low should move
across the gulf and through SE ak tue. After that, there may be a
couple of weaker systems that might move in toward midweek, then
looking like late week into the weekend will see upper ridging
developing over much of the gulf and SE ak. Used mainly the 12z
gfs to handle things through 00z tue, then wpc nbm after that. Did
use 21z SREF to help with pops through late Sun night.

One of the main model issues is how far E the developing low will
track before it curves back and merges with the parent low. 12z gfs
represented a middle ground compromise, taking low into the
central gulf, with the 12z canadian further W and the 12z ecmwf
further e. The timing of the occluded front moving onshore was
slowed some. Overall, system looks fairly wet and windy, but with
the main upper level jet sinking S fairly early in the period, a
prolonged heavy rain event is less likely with the front. May get
some heavier precip Mon night into Tue as the combined low moves e
and onshore flow increases.

Precip chances look like they will decrease for the latter half
of the long term as upper ridging takes over across the area.

Still some important amplitude and positional differences to work
out with the placement of the ridge axis, so cannot completely
remove mention of precip further out yet.

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.
