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 230359 afdpqr area forecast discussion national weather service portland or 859 pm pdt Sat jul 22 2017 Synopsis A weak upper trough will pass over washington on Sunday for a slight increase in onshore flow over southwest washington and northwest oregon, bringing a bit of cooling to to the coast and to the northern willamette valley. An upper ridge will build over our forecast area on Monday and Tuesday for a warming trend. An upper level low to our southwest may produce some thunderstorms in the lane county cascades Sunday through Tuesday afternoon and evening. Increased onshore flow and cooler conditions are expected for the second half of next week, bringing temperatures back to near normal. Short term Tonight through Tuesday... A fair amount of low clouds were solidifying along the washington and oregon coasts this evening and will spread inland later tonight and Sunday morning as an upper trough passing by to the north on Sunday results in increased onshore flow. While Saturday afternoon temperatures reached the lower 90s in most valley locations, we should see about 5 degrees o cooling Sunday, especially north. There is a developing upper low off the coast of california which will move to near the northern california coast Sunday and linger through at least Tuesday. Southerly flow develops aloft ahead of the low and will likely result in increasing higher level moisture and instability over the southern portion of our oregon cascades for a chance of thunderstorms Sunday afternoon through Tuesday, especially during heating in the afternoon and evening hours. This appears to be the most significant chance of lightning with the potential for fire starts in the cascades so far this summer. Models show that any moisture that does form will be high level and not likely to produce any significant precipitation from these storms. The southerly flow combines with the upper ridge to the north of the low for warming on both Monday and Tuesday, with highs in the valley in the lower 90s on Monday and upper 80s on Tuesday. Tolleson Long term No changes. Previous discussion follows... Tuesday night through Saturday... Models are in good agreement kicking out the upper low over northern california and moving it northwest during the day on Wednesday. Weak westerly flow develops at 700mb as the low moves out it looks like the threat of thunderstorms will be greatly reduced. However, this could change if the upper low lingers, which they are notorious for doing this time of year. That could prolong convection for another afternoon and evening heating cycle. Models show a upper trough approaching from the northwest by Thursday which puts us back in wsw flow aloft and drys out the cascades ending any thunderstorm threat. Night and morning low clouds may become more extensive Thursday through Saturday with temperatures returning to near normal. Schneider |
Aviation Low clouds have moved onto the coast south of tillamook, with lifr conditions expected to continue at onp overnight tonight. Clouds will eventually make their way up to kast but expect CIGS to be a bit higher with ifr CIGS later tonight. Inland isVFR tonight, and will stay predominantlyVFR overnight. Some indication in the models that we will see some areas of MVFR CIGS move into the north willamette valley Sunday morning, but not feeling that confident since there isn't the solid cloud bank off the coast of ast just yet. If mfr CIGS do develop inland, expect them to clear by 17z-18z. Along the coast, CIGS will hold on until around 18z-21z. As winds increase along the coast, expect improving conditions at onp earlier than ast. Expect a breezy day along the coast with wind gusts up to 30 kt Sunday afternoon. Inland will become breezy as well with north winds up to 20 kt. Kpdx and approaches... PredominantlyVFR through the next 24 hours. Small chance of MVFR CIGS around 2000 ft moving into the terminal between 13-17z Sunday, but confidence is low. Gusty northwesterly winds to 20 to 25 kt possible Sunday afternoon and evening. -mccoy Marine No changes. Previous discussion follows... high pressure will continue to strengthen over the NE pacific this afternoon, while hot weather over SW oregon and NW california will help to strengthen a thermal trough over those areas. This will bring an increase in northerly winds, with gusts 25-30 kt expected across our southern waters by sunset and spreading north into our northern waters later tonight. The increasing winds will result in steep wind- driven seas. Winds will continue to increase on Sunday. Models continue to suggest that gale force winds are possible over our southern waters. However, northerly gales over our waters are relatively rare, so given that the stronger models continue to only show marginal gales will stick with our current small craft advisories for winds and hazardous seas, but would not be surprised local gusts to 35 kt. SCA conditions look to persist into Tuesday so the current advisories will likely need to be extended. Models then show an upper trough from the gulf of alaska moving closer to our waters which will likely bring a decrease in winds seas towards the middle of next week. 64 Pqr watches warnings advisories Or... None. Wa... None. Pz... Small craft advisory until 6 am pdt Monday for coastal waters from CAPE shoalwater wa to florence or out 60 nm. Small craft advisory for rough columbia river bar from 3 am to 7 am pdt Sunday. 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. |
