Fxus66 kpqr 172115 afdpqr area forecast discussion national service portland or 215 pm pdt Sat aug 17 2019 Synopsis After today's marine push of cooler air and partly to mostly cloudy conditions, temperatures will warm slowly but steadily through Tuesday. A weakening cool front will approach the coast Wednesday afternoon, bringing increasing clouds, cooler air, and a slight chance of showers Wednesday night or early Thursday. The end of the week looks dry, with morning clouds and daytime temperatures near normal. Short term Tonight through Wednesday... A fairly uneventful pattern for the next several days in terms of sensible weather. The rex block over the pacific begins to break down, with the upper high over the aleutian islands and bering sea retrograding, and the persistent upper cutoff around 42n 160w moving slowly eastward. This cutoff is eventually entrained by an upper trough dropping southward over the gulf of alaska. Heights build over the pacnw in advance of this system, with temperatures peaking on Tuesday several degrees above normal. As the aforementioned upper trough and its surface low move into the central bc coast Wednesday, a decaying cold front will drag across the pacnw late Wednesday or Wednesday night. At 18z Wednesday, ensemble mean ivt is a not-too-shabby (for august) 350- 400 kg m S over the eastern pacific as the front approaches the or wa coast, but ivt quickly diminishes as low-level southerly flow collapses in the 6-12 hours thereafter. There could be enough lingering moisture and ascent for a slight chance of light precipitation across southwest wa and far northwest or, particularly along the coast. Precipitation certainty aside, there is high confidence of a moderate marine intrusion and seasonably cooler airmass arriving by Wednesday evening. Bright Long term Wednesday night through Saturday... Following the passage of the decaying cold front Wednesday night, onshore flow persists through the end of the week. With the break down of the pacific block, westerly flow with embedded progressive shortwaves will bring

a seasonable august weather scenario for the end of the week. The timing of individual shortwaves will augment the morning cloud afternoon clearing regime, but ensemble mean heights are high enough that precipitation appears unlikely Thursday through Saturday. Bright Aviation Moderate to strong northwesterly onshore flow continues, with a lowVFR to MVFR cloud deck lingering across the region. This cloud shield will continue to gradually clear from southeast to northwest through the afternoon and evening, with clearing reaching a konp to kmmv line around 22z. Marine stratus likely reforms across nearly all of the forecast area tonight after 09z-12z. Kpdx and approaches...VFR stratus will continue to slowly lift and possibly scatter late this afternoon. Surface winds remain light. MVFR stratus likely returns around 11z tonight. Cullen Marine High pressure remains in place well offshore as thermal low pressure persists over northwestern california and southwestern oregon. The surface pressure gradient isn't particularly strong and will maintain winds closer to 15 kt over most of the waters, though a few gusts to 20 kt possible over the southern and outer portions of the coastal waters.. Meanwhile, seas holding around 6-7 feet, with a mix of a larger 8 second and smaller 15 second swell. Little change to the overall pattern through the start of next week. A front will move near the waters early next week, bringing south winds to the waters Tuesday and Wednesday. Cullen Pqr watches warnings advisories Or... None. Wa... None. Pz... None.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
