900 am pdt Sat may 27 2017

Synopsis A strong upper level ridge will remain over the
pacific northwest through the memorial day weekend, with sunny
skies and afternoon high temperatures well above normal.

Increasing onshore flow will finally cool temperatures starting
Monday night and Tuesday. Moist south flow aloft could bring a
few showers to the area from Tuesday onward.

Short term Overnight lows were mostly 45 to 55 degrees, which
is an awfully nice temp that will see highs well up into 80s in the
typically warmer locations. Low marine layer stratus is along the
coast, but that will burn off from the beaches and possibly from the
coastal waters just offshore as well. The upper level ridge axis
will shift from near the coast this morning to east of the cascades
by Sunday evening, 500mb height stays about the same but 850mb temps
around 15c today could get a couple degrees warmer. That gives most
areas away from the water into the 80s, cooler on the coast with
highs just off the beaches and a couple miles inland well in the
70s, but cooling to the 60s Monday while the interior remains warm
and concludes a four day stretch of warmth on Monday.

Long term There is a general consensus in the extended models
that the upper level ridge will shift east and an upper level
trough will develop off the coast on Tuesday. The airmass will
become somewhat unstable with the moist southerly flow aloft.

Models differ on the strength of the onshore flow on Tuesday with
the weaker GFS only showing 5 degrees or so of cooling while the
ecmwf is stronger with the onshore flow. Pops were increased a bit
with the a chance of convection Monday afternoon and evening and
perhaps a better chance Tuesday as the flow aloft backs to sse and
then even a bit more SE on Wednesday. The 00z GFS has a better
defied upper low center reaching NW oregon Friday afternoon, so the
threat of showers will continue into the end of the week.

Aviation A ridge of high pressure will remain over the region
through Sunday. Light variable or southerly flow aloft. Air mass dry
except moist near the surface toward the coast. Khqm may have
periods of ifr fog and low stratus the next couple mornings.

Otherwise ifr skies with light northerly flow after 18z.

Ksea...VFR skies with light north to northwest winds up to 8 kt
after 18z. Light variable or northeast winds after 04z.

Marine Higher pressure offshore with lower pressure inland will
result in weak onshore flow today. The flow will become nearly flat
or neutral tonight before becoming onshore again Sunday afternoon.

Small craft winds could briefly develop in the central and eastern
strait by Sunday evening.

Strengthening high pressure offshore along with lowering pressure
east of the cascades will result in stronger onshore flow Monday and
Tuesday. This will lead to the likelihood of gale force winds over
parts of the strait of juan de fuca Monday night, and possibly
Tuesday. Stronger flow off the pacific along with a 15-20 degree
temperature difference between the wa coastal beaches and the
interior wa lowlands Monday afternoon will only increase the
potential for gale force winds over the strait of juan de fuca.

Climate Friday was the 10th dry day in a row for seattle. Dry
weather is forecast through the holiday weekend. The last time
seattle had 13 dry days in a row in may was may 19th through the
31st, 1995. Felton

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.
