Partly Cloudy and Humid with Isolated Showers and Thunderstorms

Breezy and Humid Overnight

Lingering moisture and instability combined with daytime heating have resulted in isolated showers and a few thunderstorms over the Crossroads late today, but the main and persisting issue is extreme heat. With air temperatures deep into the 90s and relative humidity between 55 and 75 percent, heat index values above 105 degrees are commonplace. Expect stifling afternoons and humid nights for the next week as upper level high pressure remains the dominant weather factor. Isolated showers return for your Tuesday. Remnant moisture from Barry continues to flood the Lower Mississippi Valley, but the tropics remain quiet for now.
