A weakening stationary front extending from the Southeast northwestward to the Central Plains, combined with upper-level energy, will trigger showers and thunderstorms over the Southeast to the Middle Mississippi Valley, producing heavy rain over the Middle Mississippi Valley and the Southeast. Therefore, the WPC issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Middle Mississippi Valley through Monday morning. The associated heavy rain will cause mainly localized flash flooding, with urban areas, roads, small streams, and low-lying areas being the most vulnerable. Furthermore, showers and thunderstorms with heavy rain will develop over parts of the Southeast on Sunday. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Southeast through Monday morning. The associated heavy rain will cause mainly localized flash flooding, with urban areas, roads, small streams, and low-lying areas being the most vulnerable. In addition, showers and thunderstorms with heavy rain will develop over parts of the Northern High Plains on Sunday. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Northern High Plains through Monday morning. The associated heavy rain will cause mainly localized flash flooding, with urban areas, roads, small streams, and low-lying areas being the most vulnerable. Also the showers and severe thunderstorms will develop over parts of the Central Plains/Middle Mississippi Valley.
