Synopsis An incoming weakening frontal system will bring clouds
and a little rain mainly to the coast and north interior overnight
and Monday. Then, a strengthening upper ridge and developing low
level offshore flow will bring sunshine and warmer weather by mid
week. By the end of the week, onshore flow is expected to return for
some cooling and a threat of some showers.

Short term
The positive tilted upper ridge was over western washington this
evening and sagging southeastward. A shortwave was near 130w with
the cloud shield was spreading onshore into british columbia and
western washington. On doppler weather radar, some light
precipitation was beginning to appear about 100 miles off the coast.

Upstream, a sharpening or amplifying shortwave was near 165w and
should build an upper ridge downstream as the pattern amplifies. The
progs continue to show this trend with heights beginning to build
over western washington late Monday, continuing through Wednesday.

This trend should tend to weaken and dissipate the incoming 130w
shortwave through Monday. The greatest chance of measurable rain
should be the coast, particularly the north coast, and then taper
off to the south and east. The interior from puget sound southward
may only get sprinkles Monday. With the increase in cloud cover
Monday, daytime temperatures should be a bit cooler than highs on
Sunday. But temperatures should begin to rebound on Tuesday with
clearing skies.

By Wednesday, thermally induced lower pressure nosing northward
along the oregon coast should turn low level flow offshore for
considerable sunshine and even warmer highs with many areas in the
70s. The current forecast is on track. Buehner

Long term From the previous edition...

an upper ridge over the area will begin to shift inland Thursday. A
thermal trough just offshore will weaken but remain in place for
another sunny and unseasonably warm day. Highs will be in the 70s
most areas and some locations could reach the lower 80s. An upper
trough and a weakening front will reach the area Friday for a chance
of rain with highs cooling several degrees. The ECMWF is a bit
stronger and wetter with this system compared to the gfs. The
forecast is a blend for now. Fairly uneventful zonal flow aloft will
prevail next weekend. A warm front might clip the north part of the
area Sunday but not much is expected from this right now. Schneider

Aviation Expect increasing clouds tonight as a warm front
approaches from the west. The air mass is stable. The flow aloft is
northerly. The front will reach the area early Monday morning with
light rain mainly over the coast - MVFR to ifr conditions are
likely. The interior will see spotty light precip by 15-18z and
continue through Monday afternoon. An upper level ridge will shift
inland Monday night for drier weather. However, the low level air
mass will remain moist for low clouds and MVFR to ifr conditions. 33
ksea... Increasing clouds tonight into Monday. Light winds becoming s
by 12z. Light precip in the vicinity by 15-18z. 33

Marine High pressure over the NE pacific will maintain light
onshore flow tonight. A warm front will clip the area on Monday with
small craft advisory winds over the coastal waters. The flow will
turn offshore by midweek as a thermal trough forms along the coast.

A weak cold front will cross the area on Friday. 33

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.
