A very select few might come across a stray shower. But most will stay dry under mostly sunny skies.
Up Next: Expect nothing more than a continuation of heat and humidity on Tuesday. However, a cold front will be approaching from the northwest. As the front arrives on Wednesday, it will stimulate the development of isolated showers and thunderstorms. The latest data seem to indicate a frontal passage by Thursday.
