Synopsis A weak upper level disturbance will bring a few sprinkles
or areas of light rain to SW washington and NW oregon through this
evening. High pressure will build into eastern wa or Tuesday,
resulting in offshore flow and warmer temps through Thursday. The
next chance for rain comes around Friday, as a weakening cold front
moves into the pac nw.

Short term Today through Wednesday... A few sprinkles have been
reported around the portland metro area this morning, and as far
south as corvallis in the willamette valley. The light precip is
associated with a weak upper disturbance riding along a stalled and
poorly defined frontal zone left behind by last week's upper trough.

Weak isentropic lift should diminish this evening, bringing an end to
the sprinkles overnight. High pressure, both at the surface and
aloft, will begin to strengthen offshore tonight.

The ridge continues to strengthen Tuesday then noses eastward into
washington Tue night wed. Meanwhile, a thermal trough pushes north
along the cascades Tuesday then drifts westward Tuesday night
becoming established over western oregon Wednesday. This results in
easterly flow across the cascades to the valley with a secondary node
of the thermal trough bringing weaker flow from the valley and across
the coast range to the coast. This will bring temperatures into the
upper 70s Tuesday and into the lower to mid 80s Wednesday.

Additionally, the coast will see temperatures pushing 80 Wednesday
along the north coast where the winds will be most enhanced by the
mt. Hood mt. Adams gap followed by the lower columbia gap. By late
Wednesday, models are indicating the thermal trough on the coast
will be in the process of closing to a low center over the coastal
waters inducing onshore flow for the south coast. Weagle mh

Long term Wednesday night through Sunday... The upper ridge
continues getting pushed east by a high amplitude upper trough
digging well offshore. The surface thermal trough axis will likely
weaken Wednesday night but could still exert enough influence to
hold onshore flow at bay Thursday.

Southwesterly flow aloft dominates the flow by Thursday night with
the ECMWF being the most aggressive at advancing the upper trough
over the area. Both the GFS and euro swing a weak front toward the
area Thursday night and early Friday with the GFS showing the
frontal energy and associated precip dissipating before the front
hits land. Added in some low end pops for Thursday night and Friday
as a slight nod toward the non-zero rain threat, but potential qpf
remains meager at best.

A brief period of zonal flow is in play for Saturday and Sunday from
the combined lifting of the trough and a return of a building ridge
off the california coast. May get another weak shortwave or two
crossing during this time for very low end pop chances, mainly
across the north. Jbonk

Aviation Patchy ifr very low end MVFR CIGS at the coast which
happen to only be at the TAF sites for the time being. Should
see the low cloud lift over the next couple hours. Otherwise,
vfr CIGS start lowering today and will start obstructing coastal
terrain this afternoon. The cascades will become obscured
starting 00-04z this evening and last through much of the night.

Kpdx and approaches...VFR conditions expected through the period,
however, visual approaches look to be impacted around 04z
continuing through about 15z Tuesday morning. Jbonk

Marine No significant changes made. Previous discussion
follows. Light winds expected through the day Monday and for
most of Tuesday before northerlies increase late in the day on
Tuesday as a thermal trough builds up the coast. Expect to see
gusts over 20 knots starting around 00z Wed and continue through
mid- day Wednesday before winds switch offshore and the gradient
weakens. Beyond Wednesday winds will remain light for the
remainder of the week. Seas will remain 4 to 6 feet through the
period. Bentley

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.
