Synopsis A series of fronts will continue periods of wet weather
into next week. Snow levels will remain above the cascade passes
today and tonight. The snow levels will lower to near the cascade
passes Thursday afternoon and night, but the precipitation will be
light. There is a better chance for snow to impact the passes on
Sunday.

Short term Today through Friday... A moist front is making its way
across NW oregon this morning. A warm front associated with a low
around 450 miles off of the oregon coast will maintain rain across sw
washington and the oregon coast this afternoon and evening. This
front will slow down or stall the current front over the oregon
cascades and foothills continuing rain there too. Otherwise, the
interior valleys including the willamette valley may see a brief
break in the rain late this afternoon through the early evening, but
do not expect much for cloud breaks.

It will be a seasonally mild day with high temperatures in the low
60s which is close to daily records for the lowlands.

The cold front will then come through tonight and Thursday for a wet
holiday in most areas. Precipitable water remains above an inch with
this front, and expect an additional 1 to 2 inches of rain for the
coast, coast range, and cascades (north of lane county) tonight
through Friday night with 0.5 to 0.75 inch for the interior valleys.

Snow levels will be above the cascade passes through Thursday morning
then lower to near the cascade passes behind the front Thursday
afternoon and night as the precipitation dwindles.

A warm front passing by to the north may result in showers continuing
along the coast and SW washington Friday morning, but precipitable
water values lower considerably (~0.5 inch) and the rain totals
should be fairly light. Areas away from the coast south of salem will
be mostly dry late Friday morning into Saturday ~tj

Long term No changes. Previous discussion follows... Friday night
through Tuesday... The models say the next system spreads in with more
rain Saturday as snow levels rising well above the cascade passes.

Snow levels drop back near the passes in showers behind the front on
Sunday. A cool system moves through Sunday night and Monday with more
rain and mountain snow, followed by decreasing precipitation on
Tuesday. Basically the unsettled weather pattern will continue.

Aviation MostlyVFR inland today with a mix ofVFR and MVFR
along the coast. Cold front offshore will slowly push towards our
area today, with rain gradually increasing later today into this
evening. Front will push predominantly MVFR CIGS into the region
tonight, and will increase southerly winds at terminals along the
coast around midnight tonight and inland Thursday morning.

Kpdx and approaches... PredominantlyVFR through this evening,
with easterly winds 8 to 15 kt. Rain increasing this evening,
with CIGS lowering to MVFR this evening around 03-06z. -mccoy

Marine No changes. Previous discussion follows...

rather extensive pressure gradient across the coastal waters,
enough to maintain gusts 25 to 35 kt today, with stronger winds
stay well offshore. Cold front will slowly push across the
coastal waters tonight. This will bring the stronger gusts closer
to shore tonight. Will extend gale warning for all of the
coastal waters today through tonight. Southerly winds will be
just below gale force this am, winds will pick up again this
afternoon as the front draws nearer.

Seas generally 12 to 17 ft, but again, the higher seas will be
over the outer waters where the stronger winds reside.

Brief break in the weather for Thu and fri, with winds generally
15 to 20 kt, and seas relaxing back to near 10 ft. But, another
strong front will bring southerly gales and higher seas again on
sat into sun. rockey.

Hydrology The heavier rain over the S wa coastal mountains last
night resulted in the grays river rising above flood stage. The rain
has eased this morning, and the river level has peaked. However,
additional moderate rain over the willapa hills expected later today
and tonight will likely keep the river above flood level through
Thursday morning. ~tj

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.
