An upper level disturbance is going to be a problem into Monday and through next week. For now, sunny skies will continue in areas where smoke is not invading. By Tuesday, building clouds across the region, increasing moisture and rising instability is going to bring unstable conditions to much of the viewing area. Thunderstorms are going to be a big concern through the entire week for many areas. Even west side valleys could see isolated thunderstorms, and those areas where fires currently are burning.
This low pressure system is going to continuously hang out to our west, into next weekend. It’s exact location will have a large impact on what exact areas through the week will see the greatest threat for storm activity. The only good news is that some of the thunderstorms that do develop may be capable of dropping a good amount of rain. Others though, will still threaten land and wildlife with lightning strikes.
For now, the warming trend will continue into the next several days, not exactly helping firefighting efforts. Winds into Sunday morning will shift to the Northeast again. This will drive smoke further west into Curry County as well as the Illinois Valley. By Sunday afternoon and evening, winds will begin turning more northerly and northwesterly, bringing smoke to places south of the fires and further inland. That trend will be ongoing through the start of the week.
