A look ahead

Perhaps a touch warmer for Saturday, but still mainly mid-80s to near 90. There's an outside shot at a late-day shower or storm. Confidence: Medium

A bit higher chance for some showers, maybe a thunderstorm, at some point on Sunday, which also means more clouds. Otherwise, still floating around near normal for temperatures with highs in the mid- and upper 80s. Confidence: Medium

More bubbling summertime conditions into the early workweek. Nothing extreme, but daily highs aren't far from 90 and an afternoon storm chance for Monday and Tuesday. Confidence: Medium
