 Warm weather and sunshine along the Gulf Coast will result in afternoon showers and thunderstorms developing due to the heat and humidity. Afternoon showers and thunderstorms are also likely from the Great Basin and the southwest into the Rockies. We'll have scattered showers and thunderstorms from Maine to Florida today due to a weak frontal system. Upper Level O will be responsible for the scattered showers and thunderstorms moving through the Great Lakes region and also over parts of the Ohio River Valley. I'm Rob Carolin, Bloomberg Radio.
