166 FXUS66 KPDT 102126 AFDPDT Area Forecast Discussion National Weather Service Pendleton OR 226 PM PDT Wed Jul 10 2019 .SHORT TERM... Today through Sunday Night...Rather benign weather is expected with near seasonal temperatures and mostly dry conditions. For the rest of today, expect scattered to overcast high and mid level clouds to linger as southwesterly mid level flow continues. Showers have persisted much of the day across portions of western Washington. Some of this moisture will likely crest the Washington Cascades, with light rain likely over their east slopes. Other isolated shower activity is possible over the Blue and Wallowa Mountains of northeast Oregon and far southeast Washington. This activity will diminish quickly around sunset with loss of daytime heating. For Thursday and Friday we will remain in a generally unchanged weather pattern with broad strong ridging to the south and a trough centered off the Pacific Coast. This will place the Pacific Northwest within a persistent southwesterly flow scenario, favoring high temperatures near to just slightly below seasonal norms (generally in the mid 80s to lower 90s lower elevations and 70s mountains). and a very low chance of showers and a stray storm across the Blues and Wallowas of Northwest Oregon/southeast Washington. 79/Austin .LONG TERM... Saturday through Wednesday...Fairly good model consensus for the period with ridging over the central US stretching back towards the desert southwest as the Four Corners' high continues to build. In addition, trough will likely remain just off the PacNW coast, keeping the region under continued southwest flow aloft. Shortwaves will rotate around the base of the trough into the PacNW and could fire off showers and possibly even a few storms but models do differ on timing of these systems. The best potential looks to be Saturday and Sunday with better instability and lift as a stronger disturbance works onshore. Lowered heights aloft with the trough proximity will help keep temps near to slightly below average for this time of year. Saturday will still be quite warm with highs in the mid 80s to mid 90s but will lower down into the upper 70s to near 90 from Sunday on. Typical afternoon/evening breezes expected through the Cascade gaps and passes, especially the Columbia Gorge and Kittitas Valley, with a thermal trough over eastern OR/WA. 84 && .AVIATION...00Z TAFs... VFR conditions with continued mid to high level cloudiness with bases fluctuating between 6-10kft. A disturbance moving through will bring a few showers and possibly isolated storms through evening, mainly over the mountains, but don't have enough confidence to include in any terminals. The best potential would be near PDT and ALW later this afternoon into early evening. Westerly winds will pick up to around 8-15kts with higher gusts possible this afternoon and evening, especially at DLS. 84 && .PRELIMINARY POINT TEMPS/POPS...
