A front extending from the Upper Mississippi Valley to the Central/Southern Plains on Friday will move eastward off the Eastern Seaboard by Sunday afternoon. Showers and thunderstorms will develop along and ahead of the boundary from the Upper/Middle Mississippi Valley to the Central Plains. Severe thunderstorms will develop over parts of the Southern Plains and the adjacent Lower Mississippi Valley. Therefore, the SPC has issued an Enhanced Risk (level 3/5) of severe thunderstorms over parts of the Southern Plains and adjacent Lower Mississippi Valley. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. In addition, the system will produce moderate to heavy rain across parts of the Southern Plains and the Lower Mississippi Valley through Saturday morning. Therefore, the WPC has issued a Marginal Risk (level 1/4) of excessive rainfall over parts of the Lower Mississippi Valley and the adjacent Southern Plains through Saturday 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. On Saturday, showers and severe thunderstorms will redevelop over the Southern Plains and the Lower Mississippi Valley. Therefore, the SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the Southern Plains and adjacent Lower Mississippi Valley through Sunday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. Moreover, on Sunday, rain will develop along the East Coast, along with showers and thunderstorms over the Gulf Coast that will linger over southern Texas on Sunday evening. Meanwhile, an upper-level trough over the Northern Rockies on Friday will persist through Sunday. The system will produce late-season light snowfall over the higher elevations of the Northern Rockies, the Northern Intermountain Region, and the Sierra Nevada Mountains Friday night into Saturday, and over the Great Basin and Central Rockies Saturday into Sunday. An approaching cold front over the Northeast Pacific on late Saturday morning will produce rain over the Northwest on late Saturday and the Northwest and Northern California on Sunday.
