 That excessive heat warning in effect for the afternoon. Storm chances, like yesterday, will be isolated. But nonetheless, those that come together could pack a punch with some damaging winds, some heavy downpours. So be alert for that. Temperatures into the 80s overnight with any storms tapering off. Upper 90s tomorrow, but feeling like 105 or greater. Scattered storm chances through the afternoon. Ushers in some cooler weather late week.
