southeast alaska forecast discussion
national weather service juneau ak
522 am akdt Thu jun 20 2019

Short term Satellite imagery and surface analysis indicate high
pressure over the gulf with marine layer stratus clouds expanding
se over the gulf and along the outer coast this morning. Expect
this layer to recede slightly during the day with increased
sunshine allowing temps over the inner channels to rise into the
60s and even push 70 in some areas. Marine layer is expected to
advect back onshore again tonight and retreat from coast fri
afternoon. The period of warm and dry weather over the panhandle
will be short lived as high pressure gives way to a low moving
into the SW gulf fri. Increasing cloud cover and precip chances
expected heading into the weekend. Thermal gradient will help
drive near SCA winds in lynn canal Fri afternoon otherwise
strongest winds will be in the afternoon evening near cape
spencer and decision today and fri. Forecast confidence in
synoptic pattern remains above average with the biggest forecast
challenge being the evolution of the marine layer over the gulf
and outer coast through the period. Minor edits to forecast to
account for current trends and add detail to winds Fri night.

Long term Saturday through Thursday night ... The gulf of
alaska will be dominated by a large upper level low that will
extend all the way down to the surface at the start of this long
range forecast period. The associated front will just be coming
ashore Saturday morning. Model trends since Tuesday night have
carried the front farther inland and maintained it farther north.

Opted to honor this shift and have made corresponding changes to
the pop grids. It now appears that locations from CAPE spencer
south on the outside and berners bay south on the inside will see
some rain on Saturday. One constant from earlier forecasts
concerning this front is that this will most likely be a low-qpf
event. In spite of favorable upper level support over the gulf,
this front will have to get past or otherwise displace a very
strong surface ridge. What is left of the front when it arrives
over land will weaken rapidly. Have rain transitioning to showers
by Saturday evening. As the associated surface low weakens and
departs the forecast area to the southeast Sunday night, easterly
wave showers will move into the forecast area from british
columbia and the yukon. Farther west, there is some substantial
model disagreement on whether or not a strong surface ridge will
build back into the central gulf or a weak low will drop south out
of south central alaska mid week. Current forecast thinking
reflects the surface ridge building back in as depicted by ecmwf
and wpc.

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.
