High pressure over the Great Basin will strengthen this week, bringing warmer temperatures and a return of the monsoon flow for possible afternoon thunderstorms by the weekend. Clear and mild tonight with light winds and lows in the 50s. Mostly sunny and warmer on Wednesday with highs in the mid-80s. We'll also see a few afternoon clouds as mid and upper-level moisture begins to trickle in from the southeast. High pressure will shift a little further to the east, putting us in a more favorable southeast flow to draw deeper monsoon moisture into the region. This will bring a better chance for afternoon showers and thunderstorms beginning Thursday and persisting into the weekend. Temperatures will start to come back down as a result of the increased humidity and cloud cover. Near-normal temperatures are forecast into next week with a slight chance for afternoon thunderstorms continuing.
