Short term A short-wave tracking north from the north pacific
will carry just enough strength to nudge our upper level ridge,
which has been responsible for our string of warm dry days east
into western canada tonight and memorial day. As a result rain
will likely spread into yakutat tonight and persist into the
holiday. Elsewhere parades and outdoor ceremonial observances for
the holiday will be rain free with partly to mostly sunny skies.

Temperatures will be largely above normal again tomorrow ranging
from low 60s to low 70s. A stronger short- wave will swing
farther eastward across the rest of the panhandle Monday night and
Tuesday. This will progressively invite clouds into the rest of
the panhandle and at least give the northern panhandle a chance of
rain. Unfortunately, the southern panhandle, plagued with extreme
and severe drought looks to remain dry until at least the next

As a surface ridge blankets the region with very light gradients,
we are not expecting any significant winds through the period.

Thus winds will largely be dictated by mesoscale thermal gradients
like local channel breezes and stronger sea breezes through the
inner channel gateways like cross sound and CAPE decision. We did
switch the far southern panhandle including ketchikan from
northwesterly to southeasterly Monday night and Tuesday and
lowered temperatures in response to a weak frontal passage.

Overall synoptic forecast looks good. Forecast confidence is above

Long term Wednesday through Sunday as of 10 pm Saturday long
range period mainly features a gradual change to a wetter and
cooler pattern by late week. The upper ridge that provided the dry
and warm weather this weekend will gradually be pushed east
through the period and will nearly be non-existent over western
canada by next weekend. The ridge does try to rebuild over the
eastern gulf Wed into thu, but an incoming trough from the SW will
push it out before it can really anchor itself. Meanwhile the
rather persistent upper low over the eastern aleutians will remain
in place and even expand its influence into the eastern gulf and
panhandle by next weekend. This will result in more SW onshore
flow aloft by next weekend.

At the surface, the main question for the long range is when wet
weather will return. The answer right now seems to be not until
late week as a incoming front attempts to dislodge the persistent
surface ridge over the eastern gulf. Some differences on timing
of the front from guidance, but most are generally settling on
Friday at this time. There also is a slight possibility of some
light rain Tue as a trough tries to push through the ridge, but
this feature is rather weak and will likely mostly produce clouds
rather then rain. With the persistent ridge and the dry weather,
winds will be rather low across the area (only afternoon sea
breeze circulations will produce anything more then 10 kt).

Temperatures will also be somewhat warm with mainly 60s for highs
and 40s for lows. High temperatures expected to become closer to
average this weekend.

Overall changes were minor. Main change was a push of the surface
ridge axis a little farther W on Wed and Thu which brought more
nw winds along the outer coast at that time.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
