This NOAA satellite image taken Sunday, April 03, 2011 at 10:45 AM EDT shows widespread cloud cover spanning areas from the Great Basin through the Upper Great Lakes and the Ohio Valley as a strong low pressure system treks northeastward into the Upper Mississippi Valley. Strong winds associated with this system draws moisture from the Gulf of Mexico northward into across the Eastern Valleys and the Great Lakes through the day. Moisture interacts with energy along an associated warm front that extends from the Mid-Mississippi Valley through the western Tennessee Valley and kicks up areas of rain, sleet, snow, and scattered thunderstorms in the Midwest, Upper Great Lakes, and Ohio Valley. There is a moderate risk of severe weather activity from northeastern Kansas into northern Missouri and a slight risk of severe weather activity from eastern Kansas and Oklahoma northeastward to the southern Lake Michigan area. Meanwhile, moisture also wraps around this system and pools along an associated cold front that reaches from the Central Plains through the Great Basin. Much colder air follows this cold front and supports the development of colder daytime highs and light snow in parts of the Intermountain West with heavy snowfall in portions of PORTIONS eastern Utah and western Colorado.
