southeast alaska forecast discussion
national weather service juneau ak
505 am akdt Mon aug 20 2018

Short term through Tuesday night strong upper ridge will give
way to a trof lifting NE across the gulf and into NW canada by tue
night. Occluded front over the W gulf will drift slowly e,
reaching the eastern gulf Tue morning, then accelerate across se
ak Tue afternoon and night. Did slow the front moving into the
panhandle by about 6 hrs from the previous forecast. Otherwise,
made mostly smaller changes to the forecast.

Did make some wind tweaks for the E gulf tue. Models suggest a
wave lifting N through the eastern gulf that will increase pre-
frontal winds some, with 25-30 kt SE winds likely over the ne
gulf. Other adjustments to winds were more minor, mostly in the
early on periods to take current winds into account. Still looks
like strongest winds over the inner channels will be near the time
of frontal passage.

The more significant rain was slowed down some due to the slower
frontal movement. Still looks like fairly heavy rain for the ne
gulf coast tue, with a quick burst of moderate rainfall possible
over the northern areas late Tue afternoon and evening as front
moves through. Not expecting any hydro issues, as the expected
rainfall will not be enough for rivers and streams to rise out of
their banks.

Otherwise, pretty much stayed with the previous temp forecast for
today and tue. Still looks fairly warm over the S with some
locations potentially reaching 80 degrees. Areas further N should
reach the upper 60s to mid 70s today, although high clouds moving
through may limit warming a bit over the far n.

Long term Wednesday through Sunday ... Heavy rain over the
northeast gulf coast at the end of the short term forecast period
will diminish somewhat as the front progresses south and east
over the panhandle. Drier conditions are forecast for Thursday as
a ridge of high pressure shift east over the panhandle, but the
break will be short lived. What was being depicted as a short wave
riding over the top of a large surface high over the gulf is now
looking more like a fully developed front with a surface low
located south of prince william sound Thursday night. Model
agreement with regard to this feature is better tonight, and
confidence is higher, but differences are still evident in the
track of the low and the timing of the front as it crosses the
gulf and spreads rain across southeast alaska. Regardless of model
differences, it does look like the coming weekend will be rainy.

Revised pressure grids for Wednesday have less of a southerly
pressure gradient over the far northern inner channels. Diminished
winds down to less than small craft intensity as a result for
Wednesday, Thursday, and Friday with 10 to 15 kts during the
overnight hours for all three days. Winds over the eastern gulf
also looking like they will remain in the 15 to 20 kt range.

No significant adjustments to temperatures with this long range
forecast. Daytime highs are expected to trend right around normal
for late august with overnight lows a degree or two above normal.

Blended GFS and the canadian nh model for updates to pressure with
gfs as the foundation for updates to wind. Blended GFS and sref
with some manual adjustments for pop and qpf. Overall forecast
confidence is average.

Ajk watches warnings advisories
Public... None.

Marine... Gale warning for pkz052.

Small craft advisory for pkz051.

Small craft advisory due to seas for pkz022-041>043.

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.
