The boundary will produce scattered rain showers in the morning over the Northeast to the Mid-Atlantic and showers /thunderstorms in the afternoon into the evening from the Mid-Atlantic to the Southern Plains/Gulf Coast. In addition, showers and severe thunderstorms will develop over parts of the Southern Plains on Sunday. Therefore, the SPC has issued an Enhanced Risk (level 3/5) of severe thunderstorms over parts of the Southern Plains on Sunday. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. The showers and thunderstorms will produce heavy rain. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall with these thunderstorms over parts of the Southern Plains. 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 Monday, the threat of excessive rainfall decreases over the Southern Plains, while showers and thunderstorms continue to develop over parts of the Southeast to the Lower Mississippi Valley. Meanwhile, a weak front develops over the Northern High Plains on Sunday evening and moves into the Northern Plains/Middle Mississippi Valley by late Monday, producing scattered showers and thunderstorms over the Northern Plains/Upper Mississippi Valley.
