PHOENIX (AZFamily) — A ridge of high pressure that could bring moisture into Arizona will not, because it’s moving east from New Mexico and will remain over Arizona for several days.
That will allow temperatures to near records around the state and greatly reduce the chances for thunderstorms, even in the mountains.
We have First Alert Weather Days for Friday and Saturday, with Saturday being the hottest of those two days and another set of First Alert Days for extreme heat next Wednesday and Thursday. It’s possible that by Thursday, we could see a high of 117 degrees in Phoenix.
With a few exceptions, not much moisture will be allowed into the state due to the position of the high, which will both block moisture from coming into Arizona from the south and catch the rest of the moisture, sending it west into southern California.
We ended July with an average high of 107, which is much cooler than the average high in July 2024 of 112 degrees. While last July was the second-hottest on record for Phoenix, the July we’re just finishing up ranks as the ninth warmest.
