 Good evening. It's a warm and muggy night with mostly clear skies overnight. Lows only dip into the mid to upper 70s. The scorching heat returns Tuesday. Highs are in the mid to upper 90s with a heat index likely over 105. It'll be partly cloudy with a chance for some late day storms. Wednesday, partly cloudy with a better chance of scattered storms. Highs climb back into the mid 90s with high humidity. I'm meteorologist Kat Campbell in the Weather Center.
