Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

southeast alaska forecast discussion
national weather service juneau ak
516 am akdt Sat jun 23 2018

Short term through Sunday night first part of the weekend
shaping up to be somewhat quiet. Another upper level short wave
moving through the northern panhandle this morning is responsible
for the clouds over the north and the 20 kt southerly winds in
lynn canal, but other wise skies range from mostly to partly
cloudy with low winds.

Forecast remains quiet for today as we await the next low coming
up from the sw. Sky conditions will vary depending on where you
are. Northern panhandle will potentially see some decent sunny
breaks today as general flow starts to turn offshore while the
southern panhandle will see increasing clouds as the leading cloud
shield from the next low approaches. Some guidance is still
currently overestimating the rain potential across the panhandle
for today given that very few places in the panhandle have even
seen a trace of rain over the last 24 hours. As such today's pop's
lean more to the dry side of the curve.

Sat night into sun, sees the return of wetter weather as a low
swings well south of the panhandle. The associated frontal bands
are expected to impact the panhandle starting Sat night and
continue into Sun with most of their effects being felt in the
southern panhandle in the form of rain and some stronger winds (10
to 25 mph SE winds). Farther north, the question becomes how far
north the rain will get as the frontal bands will be falling apart
due to divergence and offshore flow the farther north they get.

Most guidance is suggesting that at least a chance of rain is
possible for most of the panhandle except yakutat on Sun so left
pops at chance for many areas on sun.

Overall changes to the forecast were minimal with local effects
being the main concern. Used GFS and NAM for guidance in the short
range.

Long term Monday through Saturday ... An upper level low will
continue its trek as it swings inland from haida gwaii over to
british columbia Monday while a flattening ridge moves in over the
gulf. Zonal flow pattern will continue over the gulf through
Tuesday. Isolated to scattered showers are possible Monday and
Tuesday. Also watching the mid level low possibly redeveloping
over northern bc which could send an easterly wave over the inner
coastal mountains.

A surface ridge builds in over the eastern gulf Tuesday night
with surface winds over the gulf backing from westerly to
southerly into Wednesday and Thursday. The models continue to
suggest a frontal feature will slide into the central gulf
Wednesday. The front will likely shear and stall in the eastern
gulf. The upper low near the aleutians will continue to drive
weather across the gulf through later in the week, so left chance
of rain across the panhandle.

The operational models continue to follow along a similar line of
thinking as with the wpc solution. Minimal changes were made to
the forecast using a GFS ec blend for adjusting pop. Also nudged
winds on Friday towards the wpc.

Ajk watches warnings advisories
Public... None.

Marine... Small craft advisory for pkz012.

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.
