 Frontal system will produce scattered showers and thunderstorms today along the east coast from Maine to the Carolinas and Florida. We'll also see a weak system bringing showers and thunderstorms to portions of the plains in the western Ohio River Valley region. Afternoon showers and thunderstorms are likely across parts of the southwest and they'll extend into the southern Rockies. The heat persists across much of the western United States, but it will start to break over the next few days. I'm Rob Carolin, Bloomberg Radio.
