Upper-level energy and moisture flowing northward off the Gulf of Mexico will help produce showers and thunderstorms over parts of the Southern Plains, Southern Rockies, and the Lower Mississippi Valley from Friday into Sunday morning. On Friday, showers and thunderstorms will produce heavy rain over the Southern Plains. Therefore, the WPC issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Southern Plains through Saturday morning. The associated heavy rain will mainly cause localized flash flooding, with urban areas, roads, small streams, and low-lying areas most vulnerable. Moreover, a front extending from the Upper Mississippi Valley to the Central Plains will move into the Great Lakes by Saturday morning. The boundary will trigger showers and severe thunderstorms over parts of the Central Plains and the Middle Mississippi Valley. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the Central Plains and the Middle Mississippi Valley through Saturday morning. The hazards associated with these thunderstorms include frequent lightning, severe wind gusts, hail, and the threat of tornadoes. In addition, the showers and thunderstorms will produce heavy rain. Therefore, the WPC issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Middle Mississippi Valley/Central Plains through Saturday morning. The associated heavy rain will mainly cause localized flash flooding, with urban areas, roads, small streams, and low-lying areas most vulnerable. On Saturday, the front moving into the Northeast/Ohio Valley will produce severe thunderstorms. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the Northeast/Ohio Valley from Saturday through Sunday morning. The hazards associated with these thunderstorms include frequent lightning, severe wind gusts, hail, and the threat of tornadoes. Furthermore, heavy rain will develop over part of the Southern Plains and adjacent areas of the Lower Mississippi Valley. Therefore, the WPC issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Southern Plains/ Lower Mississippi Valley from Saturday through Sunday morning. The associated heavy rain will mainly cause localized flash flooding, with urban areas, roads, small streams, and low-lying areas most vulnerable. Also, a front moving over the Northern High Plains will trigger showers and severe thunderstorms. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the Northern High Plains from Saturday through Sunday morning. The hazards associated with these thunderstorms include frequent lightning, severe wind gusts, hail, and the threat of tornadoes. On Sunday, showers and thunderstorms will develop over parts of the Central/Southern Plains and Middle/Lower Mississippi Valley, producing heavy rain. Therefore, the WPC issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Central/Southern Plains and Middle/Lower Mississippi Valley on Sunday. The associated heavy rain will mainly cause localized flash flooding, with urban areas, roads, small streams, and low-lying areas most vulnerable. Elsewhere, onshore flow over the Pacific Northwest will produce rain over the area through Sunday morning. Upper-level energy moving over the Northern Intermountain Region will produce rain over parts of the Northern High Plains and Northern Intermountain Region from Saturday night into Sunday.
