Synopsis Seasonable weather through this weekend, with areas of
morning clouds. Warmer weather is expected next week with interior
temperatures likely warming into the upper 80s to lower 90s.

Short term Today through Monday... Ridging beginning to build over
the pacific northwest today bringing dry and warming conditions. Not
much change to the forecast through the weekend. The ridge won't get
much more space to build after today as an upper trough drops
southeast out of the gulf of alaska. This flattens the ridge starting
Friday afternoon, keeping temperatures seasonable through the
weekend. As large scale upper troughing moves over the area Friday
night into Saturday, may see a weakening front clip the SW washington
coast and willapa hills for a slight chance of rain, but expect dry
conditions elsewhere. Ridging begins to build again on Sunday,
starting a more significant warming trend into next week. Bowen

Long term Monday night through Thursday... Stronger ridging builds
next week, but confidence remains low in exactly how hot temperatures
will get. Models diverge by Tuesday regarding the location and
strength of thermal troughing, which will have a significant impact
on temperatures. If troughing builds such that we end up with strong
offshore flow, temperatures next week could be quite hot - at least
in the mid 90s for a day or two. But if offshore flow is limited,
temperatures will remain slightly more moderate, maybe reaching 90
for a couple of days. The place with the biggest swing based on the
flow pattern will be the coast, which can get just as hot or even
hotter than inland areas with strong offshore flow but otherwise
remains quite moderate. Didn't make a ton of changes to the forecast
temperatures in the long term period due to significant model changes
in the last 24 hours and previously mentioned model discrepancies.

Bowen

Aviation Dry westerly flow aloft, with variable high clouds
through fri. Will see areas of ifr stratus along the coast later
tonight into early Fri am.

Kpdx and approaches... Dry air mass with westerly flow aloft will
maintainVFR through fri, with variable high clouds. Rockey

Marine High pressure steadily rebuilds through late this
afternoon, tightening the pressure gradient against the thermal
low along the south oregon and north california coast. The
central oregon coastal waters should see winds gusts to 25 kt
later this afternoon and tonight. An advisory has been issued for
this event. High pressure weakens later Friday and into the
weekend as a weak trough moves through. The high pressure
strengthens again early next week.

Seas around 7 ft with 10 to 11 second periods, but should
subside through Friday to around 4 to 5 feet with 7 to 9 second
periods.

Pqr watches warnings advisories
Or... None.

Wa... None.

Pz... Small craft advisory until 5 am pdt Friday for waters from
cascade head to florence or from 10 to 60 nm.

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.
