Area Forecast Discussion National Weather Service Pendleton OR 1037 AM PDT Thu Aug 7 2025 Updated Aviation Discussion .AVIATION...18Z TAFs...VFR conditions to prevail through the period. SCT-BKN CIGS around 4kft AGL will continue to impact sites RDM/BDN into the early afternoon, with CIGS otherwise above 10kft AGL through the rest of the period for all sites. Breezy west to northwest winds 12-20kts with gusts up to 30kts will impact sites DLS/PDT through 7Z, becoming 12kts or less overnight and through the remainder of the period. Winds 10-15kts with gusts up to 25kts will impact site YKM through 4Z, and site ALW through 00Z, and RDM/BDN through 3Z, becoming light through the rest of the period. Winds will be 12kts or less at site PSC through the period. Lawhorn/82 PREV DISCUSSION... /issued 142 PM PDT Wed Aug 6 2025/ DISCUSSION...Stratiform precipitation currently moving through the region as a front pushes through. Most precip will be light albeit expecting some isolated thunderstorms to develop near WA Cascade/Cascade Crest in the early afternoon hours. Additional daytime heating and some CAPE developing near ~250 J/KG will be enough to trigger a pop-up storm. Not expecting a widespread event, but some storms could produce some gusty outflow winds and pea size hail. Not expecting significant amounts of precip, but wetting rains (>.10" inch per 24 hours) is very possible (>90% chance) with NBM showing up to a half inch falling overnight where the heaviest storms are. SPC does not have this area in a risk, so not expecting anything severe overnight. Cooler temperatures will continue today and tomorrow as a shortwave continues to push into the area with highs in the upper 70s to lower 80s for much of the Basin and other mountain regions. This will provide adequate lifting and moisture for thunderstorms to shift towards SE Washington/NE Oregon as the shortwave progresses to the east over the next 36 hours. Thunderstorm chances shift to the Wallowas, Eastern Mountains, and parts of SE Washington. Not expecting as much QPF as the storms we'll have in the Cascades, but they will have the same possible hazards of gusty outflow winds and pea size hail. Fire weather conditions will be tamed very much thanks to the wetter, cooler weather. Not expecting any Red Flag criteria to be a concern until we head into early next week as ridging starts to take over the synoptic pattern. Drying and warming will take place starting the work week, which will come with low RH, high temperatures concerns. NBM currently doesn't show widespread event of low RH, but small pockets of overlap begin to pop-up. Additionally, heat concerns make a come back with the ridge building in heat, temperatures could reach triple digits in small parts of the Basin. HeatRisk only shows widespread "2"s but only a small pocket of Major "3"s. Will need to keep an eye how strong/weak the ridge develops as it will tell us a clearer story of how hot temperatures will be. NBM clusters are split about pushing on a stronger or weaker ridge. For now, we don't anticipate any heat highlights with current forecasts, but will always need to monitor for any possible trends that favor heating concerns. && .PRELIMINARY POINT TEMPS/POPS...
