The heat and humidity peak Saturday as highs surge into the upper 80s, thanks in part to a southerly breezy gusting up to 30 mph. Sunday is the transition day, rain is likely, with possibly thunderstorms. Downpours could bring more than one inch in total rainfall through Monday morning. The start of next week will feel more like fall but the warm season does not look to be over yet.

Tonight: Mostly clear. Low of 66.

Saturday: Partly cloudy, breezy. High of 88.

Sunday: Showers and storms, heavy rain possible. High of 78.
