Update 840 pm Convective activity has decreased
significantly across western wa this evening. Just a few showers
remain as of 840 pm. Additional hit miss showers will remain
possible overnight, though thunder appears unlikely. -wolcott-

Synopsis An upper level trough approaching the area will move
over the pacific northwest on Wednesday. The low will be over the
area until late Friday. The low will slide east on Saturday with a
weak trough over the area on Sunday.

Short term tonight through Friday Satellite imagery shows
high clouds over much of W wa this afternoon with mid level clouds
pushing north across the southern portions of the cwa. A band of
showers is sliding north across lewis county and into the south
sound ahead of the upper level low off the coast. A few showers
will be around through tonight with isolated thunderstorms across
the cascades. A stray thunderstorm will be possible from lewis
county into the sound sound into this evening. Temperatures will
warm a few more degrees this afternoon with highs in the upper 60s
to mid 70s.

An upper level low located near 45n 135w will continue to slide
southeast through tonight and be positioned off the central oregon
coast by Wednesday afternoon. Flow aloft on Wednesday will
transition from southerly to more southeasterly. Instability will
increase throughout Wednesday with daytime heating. CAPE values
along the cascades will vary between 700-1000 j kg, this, combined
with lifted indices from -1 to -4 will promote isolated
thunderstorm development along the crest of the cascades Wednesday
afternoon. Given the flow aloft transitioning more southeasterly,
thunderstorms may push into the foothills late Wednesday afternoon
into Wednesday evening, forecast updated to show this.

Thunderstorm activity further west across the lowlands will be
dependent on the degree to which 700mb to 500mb winds have a more
easterly component. Have kept isolated thunderstorms to cascades
and foothills, but slight possibility exists for activity to
slide further west. Temperatures on Wednesday will be in the mid
60s with a few low 70s in spots.

The upper level low will slide east over the area Thursday and be
over the pac NW through Friday. Numerous showers around W wa on
both days with isolated thunderstorm activity kept along the
southern cascades on Thursday where at least some instability
will exist. Both days will be cool with the upper level low
overhead with highs in the low to mid 60s across the area. Jd

Long term Saturday through Tuesday Guidance suggests
solutions that are a bit different through weekend but both show
similar weather for W wa. Both GFS and ECMWF slide the upper level
low northeast on Saturday with GFS being a tad faster. The gfs
develops a weak upper trough over the area on Sunday with
relatively drier weather for Monday and Tuesday as a weak upper
level ridge builds into the area. The ECMWF generally keeps an
upper level trough over the pac NW through Tuesday with
intermittent showers around W wa. Temperatures will warm into the
upper 60s to low 70s in spots for Saturday and Sunday with mid 70s
possible for Monday and Tuesday. Jd

Aviation Southwest flow aloft becomes southerly tonight as
an upper trough digs southward over the offshore waters. High and
mid level moisture is spreading northward and scattered shower
activity is decreasing this evening.

The air mass will moisten further on Wednesday with some MVFR
ceilings possible mainly west of puget sound by morning. The air
mass will become more unstable on Wednesday afternoon and evening
with shower activity increasing. Thunderstorms are possible again
over the cascades and could locally drift into the foothills and
lowlands.

Ksea...VFR conditions through the period. Shower activity is
decreasing this evening, but cannot be completely ruled out. Shower
chances increasingly sharply by 00z Thursday. Surface winds w-nw
less than 10 knots this afternoon backing to light southerly after
06z tonight. 27 wolcott

Marine An upper level low will move into the offshore coastal
waters and will linger in the region throughout the week. This
will maintain onshore flow across the area over the next several
days. Flow will be strong enough to produce small craft strength
westerlies along the central and eastern strait of juan de fuca
during most afternoons and evenings. Other waters will remain
mostly below advisory criteria. 14 27

Hydrology The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed
until then.

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory until 5 am pdt Wednesday for central u.S.

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.
