A slow-moving stationary front will keep the chance for showers and thunderstorms through the end of the week for a large section of the United States. Several low pressure systems will "ride" along the front, bringing not only the chance for flooding rainfall, but also severe weather.

As is often the case during the summer, ample moisture from the Gulf of Mexico will help to "fuel" these thunderstorm chances. Incredibly heavy rainfall rates and several rounds of storms over the same territory is a concern. Flash flooding and river flooding is likely.

On Thursday, the risk for severe thunderstorms will impact several states. From New Mexico eastward to North Carolina, thunderstorms may include gusty winds and small hail. Cities such as Lubbock, Oklahoma City, Memphis, and Nashville should stay "Weather Aware."

On Friday, a few more strong storms will be possible, especially from Dallas to Memphis.

With numerous clusters of thunderstorms expected from the Great Plains all the way to the Mid-Atlantic, the threat of flooding rain is wide-reaching through the end of the work week.

Weather models indicate that some of the highest rainfall totals will occur in the Missouri, Mississippi, and Ohio River Valleys. Widespread totals of 3 to 5 inches will be possible.

Flood Watches and Flash Flood Watches will likely be issued off-and-on throughout this period. As of Thursday, a Flash Flood Watch is in effect for parts of Kansas, Nebraska, Missouri, Illinois, Indiana, and Kentucky.
