Short term Relatively benign summer weather pattern will
continue in the short term. Upper ridge over NW canada currently
with a vertically stacked low over the western gulf. This
persistent, blocky type pattern will be the rule through Sunday
night. The upper ridge will gradually flatten and retreat
northward on Saturday as the upper low in the western gulf slides
east and southeast. A weak pv MAX rotating around the main upper
low will lift north across the panhandle on Saturday morning. This
will likely lead to some light rain developing and spreading
northward late tonight over the south and Saturday morning over
the north. Not expecting significant rainfall amounts and in fact,
many areas may not even see measurable rainfall. Thus kept pop in
the chance to low likely category for early Saturday. Main impact
will be the potential for low clouds affecting aviation late
tonight and early Saturday morning as a soupy airmass and light
winds continue.

Weak surface low will develop and slide south of haida gwaii on
Sunday as a surface ridge develops in the western gulf. Low level
flow will turn a bit more offshore and thus precipitation chances
and cloud cover should decrease across much of SE alaska on
Sunday. Under partly to mostly cloudy skies, temperatures may end
up a few degrees warmer than the past few days. As offshore flow
in the mid levels strengthens on Sunday night, guidance is
indicating easterly wave potential once again increasing over the
north. Raised pop to likely category for the haines skagway areas
late Sunday night as a result.

Long term Sunday to Friday as of 9 pm Thursday aloft the
general pattern is fairly similar but not progressive and not
supporting of strong features to spread across the area. An upper
level low west-southwest of haida gwaii roughly near 50n 140w
will weaken and drift closer to haida gwaii by mid week. An upper
level ridge from the north pacific to the alaskan interior-yukon
territory will close off through mid week and the upper ridge axis
will extent to the alaskan interior-yukon territory out of the
midwest of the lower 48 by the later part of the week.

Looking at the surface pressure pattern over the gulf and
northwest canada shows very little in way of any pressure
gradient, with weaker pressure inland, which has been supported by
the thermal heating leading to lower pressures. By the end of the
week low pressure should be trying to move from the bering sea
into the western half of the gulf and with a ridge axis setting up
over the panhandle.

Little in way of pops are expected from Sunday onward ranging
from 20 to 40 percent across the panhandle. No significant weather
systems are anticipated through next week. Daytime highs are
still expected to slowly climb for much of the panhandle into the
70s for the next week. Lows will not get that cool with lows from
the upper 40s to lower 50s.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com 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.
