A slow-moving occluded front moving across the Northern Plains will produce severe thunderstorms and heavy rain. The severe weather threat has prompted the SPC to issue an Enhanced Risk (level 3/5) of severe thunderstorms over parts of the Northern Plains through Sunday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. In addition, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall over parts of the Northern Plains through Sunday morning. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas being the most vulnerable. Furthermore, as the front moves east, over the Northern Plains/Upper Mississippi Valley, severe weather will develop over the region. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the Northern Plains/Upper Mississippi Valley on Sunday into Monday morning and over the eastern part of the Northern Plains and the Upper Mississippi Valley on Monday. The WPC has a marginal Risk of excessive rainfall over the region through Monday. Moreover, heavy rain will develop, with showers and thunderstorms, over parts of the Southern Ohio Valley from Saturday through Sunday morning. Therefore, the WPC has issued a Moderate Risk of excessive rainfall over parts of the Southern Ohio Valley. Therefore, the WPC has issued a Moderate Risk (level 3/4) of excessive rainfall over parts of the Southern Ohio Valley through Sunday morning. Upper-level energy and a front nearby will produce showers and severe thunderstorms over parts of the Southern Mid-Atlantic on Sunday through Monday morning. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall with these thunderstorms. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas being the most vulnerable. The threat of excessive rainfall will end on Monday. In addition, showers and thunderstorms will develop along and east of the Dryline on Saturday, Sunday, and Monday afternoon. Elsewhere, onshore flow will help produce rain over parts of the Pacific Northwest and into the Northern Intermountain Region, with isolated mixed precipitation at the highest elevations through Monday evening.
