This NOAA satellite image taken Sunday, April 10, 2011 at 10:45 AM EDT shows areas of widespread cloud cover over the Upper Midwest as a low pressure system lifts through southwestern Minnesota. Showers, periods of heavy rain, and thunderstorms accompany this system and develop from the Great Lakes through the Northern Plains and in parts of Nebraska. Showers in the Great Lakes are enhanced by an associated warm front that extends from southern Minnesota through Ohio. Meanwhile, severe weather activity is possible within the vicinity of an associated cold front that extends southward from this low pressure system. Parts of southeastern Minnesota, northeastern Iowa, northwestern Illinois, much of Wisconsin, and western Upper Michigan remain at moderate risk for severe weather activity, while areas from the Great Lakes through central Texas remain at slight risk for severe storms. These storms may produce large hail and tornadoes. Elsewhere, warm, dry, and windy weather create the potential for fire weather conditions from New Mexico and western Texas through Kansas and northwestern Missouri.
