This NOAA satellite image taken Friday, July 15, 2011 at 1:45 PM EDT shows clouds develop over the Upper Midwest, as well as the Southeast.

Meanwhile in the South, a stalled frontal boundary continues to trigger scattered showers and thunderstorms across the Gulf states. (AP Photo/Weather Underground) less
