The Heat Is On; A Hot & Humid Week

Scattered thunderstorms are also possible in the area on Monday both during the morning and again during the mid-afternoon and evening hours with some storms carrying a localized flash flooding and gusty wind threat. The weather will remain hot, humid, and relatively unstable in the following days with a warm, moist air mass in place creating chances for scattered showers and storms each day. However, there will still be plenty of dry hours each day.
