Synopsis Another low will was moving into western washington and
northwest oregon this morning with another round of more steady rain
and some additional high cascade snow turning rather quickly into
showers and isolated thunderstorms today. Heavy rain is possible
around the columbia river northward this morning. The primary upper
trough low will linger over washington and oregon Thursday then
slowly move east by the weekend, with showers slowly decreasing. High
pressure builds in over the weekend and continues into early next
week for some great late september weather in store for the region,
with cool nights with patchy fog but mild sunny days.

Short term Today through Friday... As expected, the layered
moisture that was well offshore early Tuesday and moved toward
southern oregon Tuesday interacted with a northern cooler surface low
that moved toward the western washington and northwest oregon coasts.

The moisture spread northward and developed into an east-west
oriented deformation zone that has slow moved north overnight. It is
now along the columbia river northward, then will move eastward later
this morning and early this afternoon. Data in southwest washington
and around mount hood show the snow level runs between 5000 and 6000
feet and have issued a snow advisory for this morning until the
deformation zone moves east. To the south of mount hood and the
deformation zone, snow levels have risen and precipitation is mostly
rain until you get to pretty high elevations.

There are quite a few showers and thunderstorms over the coastal
waters that will spread onshore this morning and cover more of the
forecast area as the deformation zone moves eastward. Snow levels
will ease back down to 5000 to 6000 feet in the remainder of our
oregon cascades this afternoon as this occurs. Thus it will stay
pretty unsettled all day today. The upper jet will be in close
proximity for a while this morning, moving southeastward into
southeast oregon later today with decreasing vertical wind shear. The
best chance for any of the convection to be strong might be more this
morning than this afternoon.

An upper low develops in the south end of the parent upper trough on
Thursday, centered over south central oregon and northeast
california. We should see some showers develop in the northerly flow
on the back or west side of the low on Thursday as some energy drops
south and due to daytime heating. The low lingers over central and
eastern oregon Friday and we should again see some showers develop on
the back side of the low, especially over the cascades.

Will continue the flash flood watch for burn areas on the oregon side
of the columbia river gorge and the north and central oregon
cascades. Rainfall rates have not reached values yet that research
says results in flash flooding in burn scars, but plenty of rain has
fallen and will continued to be monitored. Tolleson

Long term Friday night through Tuesday... An upper ridge builds
over the NE pacific this weekend and slowly expands into the pacific
northwest early next week as the inland upper low finally but slowly
moves eastward. This will bring drying and warming to the area,
though the warming will be more of the fall variety than of the
summer variety as the ground is wetter and we will probably see areas
of radiational morning low clouds and fog as nights are lengthening
and cooling. The models show some energy riding over the upper ridge
to our north that may keep some low clouds along the south washington
and far north oregon coasts at times, especially in the nights and
mornings. Tolleson

Aviation Ifr conditions have come in a bit more widespread than
expected. Have made some changes to the tafs to reflect this change.

Otherwise will be monitoring the progression of the front through the
area to try and time the improvement to MVFR orVFR at each of the
terminals.

Kpdx and approaches... Combination of low end MVFR and ifr conditions
through sunrise until the front moves through. Bentley

Marine Pushed up the timing of the small craft advisory for winds
as the front has already pushed through buoy 89 with gusty nnw winds
and gusty pre-frontal winds at buoy 50. In addition, extended the
small craft advisory for seas for the outer waters through 12z
Thursday as it appears outer waters will stay around 10 feet through
much of the period.

Quieter marine weather is expected by late this week and into the
weekend as typical summertime northerlies return to the area.

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.
