6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported. 5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive. 5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds. |

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 kpqr 211032 afdpqr area forecast discussion national weather service portland or 324 am pdt Mon aug 21 2017 Synopsis Onshore flow will produce varying degrees of morning clouds, afternoon sunshine and inland temperatures in the 70s and 80s for much of the next week. The coolest temperatures will likely be late Wednesday and Thursday as a weak storm system brings a chance for a few light showers to the area. Short term Today through Thursday... Fog product reveals marine stratus congealing over the waters and pushing onto much of the oregon and washington coastline. This stratus field is quite shallow with CIGS generally hovering a couple hundred feet agl. This should prevent too much inland penetration, but nonetheless, should see some marine clouds into at least the kelso-longview area by daybreak... And perhaps even into the eastern pdx metro towards 7-8am. Given little change in the pressure pattern, wind fields and the solar eclipse should begin to limit solar insolation around the time stratus typically begins to dissipate along the coast, suspect those along the coast that are currently cloudy will remain so through the duration of the eclipse. The good news is that away from the columbia river and willapa bay, the marine stratus should not extend more than a few miles inland. It should be noted that there will be a few passing high clouds this morning for areas that are not socked in the marine clouds. However, these clouds should be considerably thinner and more transparent than the mid-high level clouds observed yesterday. Otherwise, expect inland high temperatures to top out in the mid to upper 80s today and Tuesday. Thunder chances look to remain south and east of the region Tuesday and Wednesday afternoon and evening. The next front will approach the region Wednesday and bring cooler temperatures, increased cloud cover and a chance for some light rain showers Wednesday night and Thursday. Neuman Long term Thursday night through Monday... Shortwave ridging should build over the pacific northwest and bring a return to more sunshine and warming temperatures Friday and Saturday. In fact, some models suggest another hot spell and dangerous fire weather conditions are possible late in the weekend and or early next week, but still too early to say much more than that at this point.

Aviation Stratus deck has filled in along the coast now with ceilings between 200 and 400 feet. Kast has briefly broken out of the stratus, but expect the stratus to return and remain through the morning. The biggest question will be how quickly the stratus clears. Given that 925 and 850 winds are slowly becoming more ne between now and 18z, expect the stratus to clear quite quickly... Possibly even in time for the eclipse. However, given the slower daytime heating due to the eclipse, this may also limit mixing and cause the stratus to linger longer than otherwise expected. Kpdx and approaches...VFR conditions through the period. Still a small possibility of a few scattered clouds this morning near the terminal, but expect mostly clear skies. Bentley Marine A persistent weather pattern will result in little change in the marine weather the next several days. High pressure will continue over the NE pacific with a thermal trough of varying strength along the south oregon coast. This will lead to small craft strength winds again today in central waters. Winds should be below small craft strength through the remainder of the week before northerlies strengthen again by the weekend as the thermal trough strengthens again. Seas will remain small but steep through the period. Dominant periods will remain between 8 and 10 seconds. A rough bar is in effect for the very strong ebb this morning. Otherwise, no sea driven headlines should be needed this week. Bentley Pqr watches warnings advisories Or... None. Wa... None. Pz... Small craft advisory for winds until 11 pm pdt this evening for coastal waters from cascade head or to florence or out 60 nm. Small craft advisory for rough columbia river bar until 7 am pdt this morning. Interact with us via social media: |

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. |
