Type 2 conceptual sounding for predicting severe weather

This sounding type is common in the tropics but observed at times over much of the U.S. east of the Rocky Mountains, especially in the summertime over the Gulf Coast and Southeast. It is characterized by a deep, moist, conditionally unstable layer with relative humidities >60% from the surface up to 7 km AGL. There is no capping stable layer so that widespread convection is typically observed.
