Synopsis for southern washington and northern oregon coast.. Weak pressure will maintain benign marine weather through Saturday morning. High pressure strengthens Saturday afternoon. Daily variations of the thermal trough along the north california and south oregon coast will result in gusty winds in the afternoons Sunday and Monday. The thermal trough weakens Tuesday and Wednesday.

Synopsis A warm weekend ahead before cooler temperatures arrive
with increasing onshore flow Sunday evening. Monday will warm close
to 90 again before cooler weather arrives for the remainder of the
week. Thunderstorms are possible in the central oregon cascades, but
the main threat will remain along and east of the crests.

Short term Tonight through Sunday night... Summertime northerly
winds tomorrow will allow temperatures to warm into the upper 80s and
near 90 in the valley. Sunday will start the same, but the gradient
will become more onshore through the day which will limit heating
despite slightly warmer temperatures aloft. This will also usher in
cooler temperatures in the evening. What will likely be the most
notable will be the increasing mugginess. Dewpoints will increase to
at least the low 60s by Saturday afternoon evening with the gfs
increasing dewpoints into the mid 60s. Sunday will also need to be
watched, but uncertainty is a bit higher at this time with afternoon
dewpoints ranging from 48 to 66 depending on the model of choice.

These increasing dewpoints are associated with an area of
unseasonably high moisture off the coast with pwat values as high as
1.75" within 100 miles of the coast as of this afternoon. In fact,
bufkit soundings are forecasting pwat values near record (1.5" to
1.6") at ksle by tomorrow morning. This mugginess may lead to
increased heat related impacts than would otherwise be expected for
high temperatures near 90 degrees.

In addition to the warm temperatures, the other focus in the short
term period is the potential for thunderstorms along the central
oregon cascades Sunday afternoon evening. There has not been much
change in thinking from previous days, but due to increasing
confidence and better model continuity, have increased pops to chance
for the areas right along the crest. The main threat from these
thunderstorms will be related to recreation and fire weather,
primarily in the willamette national forest. Bentley

Long term Sunday night through Thursday... Models have started
coming into better agreement with the handling of the upper low
spinning off the california coast early next week. Both the ECMWF and
gfs hold the low offshore on Monday and start lifting it towards
central oregon on Tuesday which continues the thunder threat through
Tuesday. However, the low is also continuing to track further south
each run which is precluding any thunder threat further north along
the cascades. In addition, it is worth noting that the beginning
stages of the upper low cutting off can be seen on water vapor just
inside 140w, but the moisture appears quite limited. This lends
support for moisture being a limiting factor and the nature of the
storms being high based and somewhat dry (hence the fire weather

Besides the thunder threat Monday and Tuesday along the central
oregon cascades, dry conditions will prevail with temperatures at or
slightly below normal. Bentley

Aviation Ifr conditions should return to the coast this
evening and persist into Saturday morning. Light rain or drizzle
is possible for ktmk and kast and extreme SW wa late tonight and
Saturday morning as a warm front clips the region.VFR inland
tonight and Saturday. Light and variable winds tonight and
Saturday morning becoming onshore and increasing Saturday
afternoon adn evening.

Kpdx and approaches...VFR conditions through Saturday. Onshore
winds this afternoon will become light and variable tonight
through Saturday morning onshore winds return Saturday
afternoon. ~tj

Marine No changes... A weak surface pressure gradient
continues over the waters through Saturday morning for light
winds and low seas. High pressure increases Saturday afternoon
returning north winds to the waters. Diurnal changes in a thermal
trough over n. Ca and s. Or will result in gusty north winds
Sunday and Monday afternoons and evenings. The strongest winds
will be south of lincoln city where models are showing the
possibility for gale force gusts. The seas will increase in
response to the winds for steep and choppy conditions. Low
pressure to the south weakens on Tuesday for a slight decrease in
winds,but fresh NW swell will maintain steep seas. ~tj

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.
