We still have some hot summer weather to contend with out there, but a gradual cool-down can be expected through the weekend as the monsoon flow returns. Looking at another warm one today with highs in the upper 80s to around 90 degrees, light & variable winds to 10 mph at times. Don't expect much cooling for tomorrow as highs reach the upper 80s one more day under mostly sunny skies. High pressure over the region will shift off to our east over the weekend, a position more favorable to tap into monsoon moisture. 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, importing 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. Though, some activity could spill westward over our valley areas Monday or Tuesday. High pressure should remain in place throughout most of next week, with the heat and humidity continuing for scattered showers and thunderstorms at times.
