A slow moving storm system extending across the Plains will bring a threat for flooding to the mid section of the nation. Flash Flood Watches extend from near Lake Superior to the Rio Grande River in Texas. More than 6" of rain may fall in some areas through the middle of the week.
A strong Jet Stream coupled with high humidity will aid in producing heavy rainfall. "Summer-like" Gulf of Mexico moisture and waves of energy riding along the Jet Stream will produce numerous showers and thunderstorms throughout the week.
