It will be another hot and humid one Sunday, with highs in the upper 80s to low 90s, and dew point in the 60s and 70s. The heat index could reach 95 to 100 degrees in spots. Use caution if you’re outdoors. A few afternoon thunderstorms are possible. Monday will bring a much better chance for showers and thunderstorms. Cooler and less humid weather will eventually move in during the week.
