southeast alaska forecast discussion
national weather service juneau ak
255 pm akdt Thu jun 20 2019

Short term satellite imagery showing mostly sunny skies over
the panhandle as a ridge of high pressure has built in. There is
a large area of marine layer stratus clouds over the northeast
gulf. The area of low clouds will move back in along the coast
tonight. Temperatures this afternoon have been in the 60s for most
areas with a few spots reaching the 70 degree mark. One more day
of pleasant weather is expected on Friday as the ridge of high
pressure begins to push out of the region in response to an
approaching low in the gulf. Winds should be light across most of
the panhandle except for the northern lynn canal where SCA winds
will be present due to an increasing pressure gradient from the
thermal difference between the yukon and southeast alaska.

Clouds will begin to increase Friday night ahead of the next
weather system forecast to swing a weakening front through the
area on Saturday. Light rain moves in on Friday night and persist
into Saturday for most areas. Precipitation amounts are expected
to be light generally under 1 4 inch. Temperatures this weekend
will fall back to seasonal norms with the increasing clouds and
rain. Confidence in the forecast remains above average for the
period. Minor changes made to the forecast mainly for day 3 on
Saturday to make adjustments and add detail to winds in the inner
channels.

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.
