Synopsis A ridge of high pressure persists over the eastern
gulf through Saturday night. A weather front will move north
across the central gulf Saturday and Saturday night.

Short term Another round of good model agreement with the ridge
remaining in the gulf that keep the worst of the weather to our
west. Model guidance came from the NAM and gfs. A blend with our
anchorage forecast office at our border brought in a slight
increase to the winds over the central gulf, it did not result in
anything higher than a 25 kt starting Saturday morning for the
extreme western edges of marine zone 310 and 51.

Clouds move into the yakutat area overnight with the bulk of
the rain staying west of yakutat bay until Saturday night.

Elsewhere over the panhandle, mostly clear to partly cloudy skies
although with recent rains we could see some patchy fog form in
the overnight hours for the central panhandle. There was
significant drying today, which should keep fog impacts minimal.

Wind across the panhandle is generally 5 to 15 kt, with a weak sea
breeze in some locations this afternoon. After sunset winds
should return to light and variable over much of the area. One
location that will be a little tricky is haines area with a
southeasterly flow relaxing tonight that may allow for weak
downsloping bring a northwesterly wind to the chilkat valley late
night and early Saturday morning.

Long term Saturday night through Thursday as of 10 pm
Thursday. Generally only a few small changes to the forecast in
the mid to later time frames. The most significant change over
the weekend was the the idea that the ridge axis has been moved
about 150 miles eastward to lie more over the panhandle than
rather off shore. The result for Saturday night and Sunday for the
coastal waters is that northwest winds along the outer coast is
now a southerly or becoming a lighter west for the marine area
west of prince of wales island.

Forecast solution from wpc, which is what was being used for
minor changes into midweek was for the ridge of higher pressure to
persist along the panhandle coastal mountain range while a broad
area of low pressure develops and moves into the southwestern gulf
of alaska. The flow about this will be trying to spread some
moisture and rain into the eastern half of the gulf of alaska
though it may take until Wednesday before the precipitation does
so with a frontal band about the western gulf low.

The weekend ridge area of high pressure is not as substantial as
some of the thoughts in the previous forecast, and it is being
moved northward or being weakened. As a result the threat of a
widespread marine deck with the low clouds and fog bank are
lessened at least for the main gulf waters. However the high
pressure will take the marine deck that is in the eastern pacific
waters that is being maneuvered to the british columbia coast
late Saturday and start moving that north to be approaching the
dixon entrance area later Sunday into memorial day. This may end
up being pushed northward early part of next week and could lower
the temperatures there for the first half of the week.

For now left the highs in 60s to near 70 for panhandle which are
being supported by a warm layer of air that is being advected
north. Expect to see the 850 mb temperatures to rise 5 to 10
degrees c between Friday and Sunday with 850 temperatures from 4
to 10 c by Sunday.

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.
