Area Forecast Discussion National Weather Service Pendleton OR 125 PM PDT Fri Jun 13 2025 .SHORT TERM... Tonight through Sunday Night...Southwesterly flow will prevail over the region through the short term period. Several weak disturbances will move through the flow over the weekend. Any lingering precipitation over the eastern Oregon mountains should come to an end this evening. Dry conditions are expected through the period. However, some guidance is suggesting showers or even a few thunderstorms over the eastern mountains on Sunday. At this time, probabilities are very low (15%) but will need to see if chances increase over the next day or two. Breezy winds through this evening will decrease through the weekend, though there will still be some breezy locations Saturday, especially along the Cascade gaps. RH values are expected to remain in the 15 to 20 percent range in many of the lower elevation areas through the weekend. .LONG TERM... Monday through Friday...Another weak disturbance/trough moves across the area on Monday. This system will bring some rain to the Cascades into Tuesday while the rest of the region remains dry. Zonal flow then develops into Wednesday, followed by a return to southwest flow Thursday into Friday. By the end of the extended period, a large low and trough is approaching the Pacific Northwest. Gusty winds are expected to redevelop Monday afternoon and then again Wednesday and by the end of the week with the approach of the upper low/trough. Winds will generally gust in the 25 to 35 mph range in the Cascade Gaps, Gorge, portions of the Basin, Kittitas Valley. On Monday, the NBM probabilities of wind gusts >=39 mph are generally 50 to 70 percent in these areas and a bit higher in the Kittitas Valley. On Wednesday, the values are slightly lower, about 40 to 60 percent. High temperatures look to be near normal through Wednesday then about 5 degrees below normal toward the end of the week. && .AVIATION...(Previous Discussion) 18Z TAFS...VFR conditions are expected through the TAF period. However, due to area wildfires, there could be some smoke impacts at DLS/PDT/ALW/PSC which could lower VSBYS or CIGS through the period, but confidence is too low to include in the individual forecasts at this time. Breezy winds will continue at all sites except PSC through the afternoon and evening hours before decreasing. DLS will gust 25 to 30 kts, while the other locations will gust to around 20 kts. Later this evening/overnight, all sites will decrease to around 10 kts or less. DLS will gust again on Saturday afternoon to around 20 kts. && .PRELIMINARY POINT TEMPS/POPS...
