SYNOPSIS. A cool and unsettled showery weather pattern will persist through Monday before a warming and drying trend takes hold next week.
SHORT TERM. Today through Sunday . Water vapor satellite imagery continues to reveal a longwave trough lingering across the Pacific Northwest, northern Rocky Mountain states and western Canada. A large closed upper level low pressure centered over British Columbia and Alberta will continue to result in shortwave troughs and vort maxes rotating south to southeastward into the Pacific Northwest and California over the next several days.
The first storm system is currently shifting from southwest British Columbia into eastern Washington. While the best instability and forcing is expected to remain well north and east of the region today, there is enough lingering low level instability and westerly flow to allow a few showers over the northeast Pacific to continue to shift onshore. As daytime heating ramps up over the next few hours, expect shower coverage to increase slightly inland. However, instability will become increasingly squashed from a lowering subsidence inversion. This will be in response to upper level heights temporarily building across the region in the wake of the aforementioned shortwave trough shifting from southwest British Columbia/eastern Washington into northern Idaho and Montana.
The next storm system of interest is a rather compact closed low pressure currently located near 140W and 47N via satellite imagery. Models are in general agreement it will slide southeastward and reach the northern California and southern Oregon coast Saturday morning. A secondary shortwave trough currently over the Gulf of Alaska will drop southward and help to eject the aforementioned low pressure northeastward across Oregon on Saturday. This will result in a broad area of light rain and mountain snow spreading northward late tonight and Sunday morning across northwest Oregon. Models have trended a bit higher with their snow levels tonight and Sunday morning, presumably due to an extensive mid and high level cloud deck overspreading the region overnight. While cannot completely rule out some light snow accumulations on grassy surfaces around 500- 1000 feet, this should not impact travel where the bulk of the population lives across northwest Oregon.
It should be noted that there may be just enough cooling aloft and late day clearing to allow some surface instability to generate a few showers across Douglas County before spreading northeastward into Lane and Linn Counties late Saturday afternoon and early evening. While instability does not appear sufficient for thunderstorms based on model soundings and projected high temperatures, it could still end up somewhat close. Will examine this more closely with the afternoon forecast package.
It appears likely weak surface low pressure over the southern Oregon coast will shift northward into the Willamette Valley and/or the norther Oregon coast Saturday night. This will result in showers likely persisting across parts of the CWA Saturday night, but exactly where the heaviest QPF will resides remains more uncertain.
Otherwise, the aforementioned shortwave trough dropping southward out of the Gulf of Alaska today and Saturday will shift southeastward towards northern California on Sunday. In doing so, cooler temperatures aloft will work their way over the region, which should result in another round of showers bubbling up across the region Sunday afternoon and early evening. There are also hints of a band of precipitation setting up across northwest Oregon Sunday night that could result in an area of more persistent rain and mountain snow, but substantial differences in the placement and intensity of the band of precipitation exist between the models.
Models continue to suggest shortwave ridging will begin to shift over the region on Monday. While there should be enough lingering instability to generate another round of widely scattered showers in the afternoon and early evening hours on Monday , it appears Monday will be the beginning of a warming and drying trend. /Neuman
LONG TERM. Monday night through Thursday . The upper low continues to drift south off the west coast through Thursday. By late Monday it should be far enough south for any wrap around moisture to bring pcpn to our area. A ridge of high pressure should build in Tuesday through Thursday for a dry period. Ensemble models currently in agreement with this occurring. However with recent model variability will take a wait and see approach.
AVIATION. Cool northwesterly flow aloft will continue today as another weak disturbance drifts inland. This will bring spotty showers through this afternoon with occasional MVFR possible. Expect remaining low stratus in the central and south valley to lift and scatter over the next couple of hours with mainly VFR conditions through tonight under scattered to broken mid and high clouds. Another disturbance then looks to approach from the south tonight resulting in an increasing chance for rain and MVFR conditions late tonight for far southern portions of the forecast area and spread north through Saturday morning.
PDX AND APPROACHES . Spotty light showers could result in brief periods of MVFR conditions through this afternoon. Otherwise, expect VFR conditions through tonight with scattered to broken mid and high clouds. Expect to see an increasing chance for rain and MVFR conditions Saturday morning as another disturbance moves across the region from the south. /64
MARINE. Rather tranquil conditions expected across the waters for the next several days, with north to northeasterly winds less than 15 kt and seas in the 3 to 5 ft range. Low pressure well offshore will approach the south Oregon coast Sat night into Sun, then lift northward along the coast, before shifting inland over northwest Oregon on Sun. May see uptick in southerly winds along the coast south of Cascade Head, but confidence not all that good yet. Even so, winds may get up to 20 kt for a time early Sun for areas close to shore south of Newport.
High pressure will remain offshore to start next week, with weak lower pressure inland over the Pac NW. This will bring west to northwest winds 10 to 15 kt, with seas 4 to 6 ft. /Rockey

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.
