 Low temperatures dip into the low to mid-70s overnight, and Friday brings the best chance for rain in a while. On and off, showers and thunderstorms are likely. Otherwise, it's mostly cloudy and less hot. High temperatures in the low to mid-80s. Saturday, it's mostly cloudy early, then a chance of a storm. Highs are in the low 90s.
