Synopsis – THU JUL 09 2026

Dry conditions and warm temps will continue to the end of the week into the weekend. All due to high pressure building aloft over the SE. Afternoon temps will top out at about 5 – 10 degrees above normal in the Owens Valley. Further nighttime lows will stay on the warm side. As next week begins, high pressure nears 4-corners, setting up a South / Southeast flow and possibly allowing monsoonal moisture to advect into our area. Stay tuned for updates on this…DMATT
