Synopsis A front will produce rain across NW oregon tonight and
Tuesday morning. Showers will decrease behind the front Tuesday
morning, but an upper trough will support post-frontal showers in the
afternoon, and possibly a few thunderstorms across lane county late
in the afternoon. Onshore flow will support deep marine pushes
Tuesday night and Wednesday night. Gradual warming is expected
Wednesday and Thursday with a threat for showers over the cascades in
the afternoons.

Short term Tonight through Thursday... Showers will pick up this
evening as a surface low currently around 400 miles off of the north
oregon coast approaches. Satellite imagery shows a fairly well
organized front associated with this low that will begin rain at the
coast early this evening, then rain spreading inland later this
evening and tonight. The best chance for rain is over NW oregon, with
lower chances for SW washington.

The rain will decrease from north to south Tuesday morning, but then
reinvigorate over lane county,and the oregon cascades & coast range
Tuesday afternoon when the low moves inland. The cascades, coast and
coast range can expect 0.25 to 0.5 inch of rain this evening through
Tuesday morning with less than 0.25 inch elsewhere, and generally
less than 0.10 inch north of salem. Thunderstorms are possible in the
afternoon across lane county where isolated down pours will result in
local additional QPF from 0.10-0.25 inch. Temperatures will be on the
cool side with daytime highs expected to peak in the low to mid 60s.

The showers will decrease Tuesday night as an upper ridge tries to
build over the pacific nw. A large upper low moving inland across
western CONUS prevents the ridge from fully materializing. Onshore
flow and a fairly deep marine layer will result in marine clouds
moving inland Tuesday night through Wednesday morning. Diffluence
aloft between the upper low and the upper ridge moves over the region
Wednesday afternoon and provides enough instability to support a
chance for afternoon showers across the cascades.

There will be little change in the pressure pattern Wednesday night
and Thursday and expect a cloudy start to the day ton Thursday
followed by cascade showers in the afternoon. Daytime temperatures
will gradually warm Wednesday and Thursday. ~tj

Long term Thursday night through Monday... Dry weather is expected
for Friday as the upper ridge asserts itself over the pacific nw. The
ridge is not very strong though as upper troughs moving over the
ridge will return a threat for showers for the weekend. The models
are showing these troughs to deepen and form an upper low over nw
oregon by Saturday for cooler conditions and periods of rain for
Saturday and Sunday. Drier weather is possible on Monday, but expect
showers over the cascades in the afternoon as the upper low moves
inland and increases the chance for diffluent flow aloft.~tj

Aviation...VFR conditions continue this evening and likely
through at least 12z inland. However, some showers will continue
and mountains will likely remain obscured through the night.

Meanwhile, potential remains for MVFR CIGS from ksle to keug from
12z through sunrise Tuesday. Conditions improve from north to
south Tue morning as the surface low pressure area slides
southeast into southwest oregon.

Kpdx and approaches... Expect predominant lowerVFR conditions
through Tuesday morning, with some showers in and around the
terminal. There remains about a 25% chance, however, of MVFR cigs
developing between 12z and 15z.

Marine Low pressure system continues to move through the
waters, with the strongest winds remaining ahead of the low over
the southern zones. Solid small craft advisory level speeds over
the waters overnight through sunrise Tuesday.

The low looks to be centered just west of buoy 46050 early
Tuesday before pushing onshore near newport jetty mid-morning. Wind
will back to the east late tonight and Tue morning. Small craft
advisory level northwest to north wind develops over the waters
tue afternoon behind the departing low. This northerly wind
pattern continues through at least fri.

Wave heights will be in the 9 to 11 ft range tonight, and build
to near 12 or 13 ft on Tuesday. Seas then remain at or slightly
above 10 ft through at least Wednesday evening. Weishaar cullen

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.
