 A stalled frontal system will produce scattered showers and thunderstorms today from the southern mid-Atlantic region across parts of the southeast, the Tennessee River Valley, and the Gulf Coast. A few of these storms may produce heavy rainfall. An area of low pressure is going to be responsible for scattered showers and thunderstorms over the central and northern Rockies. Monsoonal moisture in the southwest will fire some showers and thunderstorms up later today from the southern Rockies to the southwest and Great Basin. I'm Rob Carolin, Bloomberg Radio.
