We still have some hot summer weather to contend with out there, but a gradual cool-down is expected through the weekend as monsoon moisture increases. Don't expect much of a cool-down today as highs reach the mid to upper 80s under mostly sunny skies. High pressure over the region will shift to our east this weekend, a position more favorable for the monsoon flow. We'll see a few afternoon clouds on Saturday, but should stay dry as highs cool slightly into the mid-80s, southeast winds developing 10-15 mph. The southeast flow aloft will strengthen on Sunday, drawing additional mid and upper-level moisture into the area for a chance of showers and thunderstorms. Deeper moisture is forecast to arrive early next week, possibly enhanced by an inverted trough generating widespread showers and thunderstorms, mainly over the mountains and deserts each afternoon. However, some activity could spill westward over our coastal valley areas on Monday and Tuesday. High pressure will remain in place throughout most of next week, with the heat and humidity continuing for scattered showers and thunderstorms at times. Another easterly wave could also move into the region later next week, coupled with additional moisture from a tropical system off of Mexico, keeping thunderstorms in the forecast all the way through next weekend.
