A quasi-stationary front extending from the southern Mid-Atlantic westward to the Southern Plains and then northward to the Northern High Plains will help trigger showers and thunderstorms over the Southeast to the Northern High Plains, producing heavy rain over the Middle/Lower Mississippi and Tennessee Valleys, as well as the Southeast. Therefore, on Friday, the WPC issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Middle/Lower Mississippi and Tennessee Valleys, and the Southeast through Saturday 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. Similarly, showers and thunderstorms with heavy rain will continue over parts of the area on Friday. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Southeast from Friday into Saturday 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. Meanwhile, showers and severe thunderstorms will develop over parts of the Southern High Plains. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the Southern High Plains through Saturday morning. The hazards associated with these thunderstorms include frequent lightning, severe wind gusts, hail, and the threat of tornadoes. On Saturday, a second front over the Northern Rockies/Northern Intermountain Region will bring showers and thunderstorms to parts of the Northern High Plains, with heavy rain. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Northern High Plains through Sunday 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. Moreover, showers and thunderstorms will develop over parts of the Northern/Central Plains, producing severe thunderstorms. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the Northern/Central Plains from Saturday through Sunday morning. The hazards associated with these thunderstorms include frequent lightning, severe wind gusts, hail, and the threat of tornadoes. The front will advance into the Northern/Central Plains by Saturday. Showers and thunderstorms will develop over parts of the Northern/Central High Plains, and some storms will become severe. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the Northern/Central High Plains on Saturday. The hazards associated with these thunderstorms include frequent lightning, severe wind gusts, hail, and the threat of tornadoes. Overnight Saturday, rain/snow will develop over parts of the Northern Rockies. Furthermore, showers and thunderstorms will develop over the Northern/Central High Plains into the Middle Mississippi Valley on Sunday.
