 Large low-pressure system brings scattered showers and thunderstorms to portions of the upper Midwest, the Western Great Lakes, the Northern Plains, the Northern and Central Rockies today. Some of the storms may produce some very heavy downpours. Another area of low pressure likely brings scattered showers and thunderstorms to portions of the Southeast and the Gulf Coast today. High pressure continues to control the weather in the West, scattered showers and storms in the Southwest. I'm Rob Carroll in Bloomberg Radio.
