High pressure will strengthen across the region through the end of the week, bringing warmer temperatures. Low pressure to our south, combined with this ridge to our east, will also gasp for one last hurrah of monsoon moisture, with a few afternoon showers or thunderstorms possible on Thursday. Daytime highs will top out in the mid-70s through Friday, with overnight lows generally in the 50s. Winds will remain from the east 5-15 mph, gusty near any thunderstorms. Drier conditions should return on Friday with cooler temperatures over the weekend as another trough develops off the West Coast. Highs will fall from the mid-70s Saturday to the upper 60s on Sunday, with gusty west winds 10-20 mph at times. Low pressure off the West Coast will draw mid and upper-level moisture into the Desert Southwest early next week for a chance of showers. Unfortunately, the deepest moisture and dynamics will stay to our south and east but expect some cooler fall weather with possible showers on Monday or Tuesday. High pressure will regain control later in the week for fair and warmer weather.
