A front extending from the Northern Mid-Atlantic to the Lower Great Lakes/Ohio Valley/Middle Mississippi Valley and Central/Northern Plains will dissipate over the Central/Northern Plains by Sunday evening. The system will produce showers and severe thunderstorms over parts of the Northern Mid-Atlantic. The SPC has issued a Slight Risk (level 2/5) of severe thunderstorms over the Northern Mid-Atlantic and the Northern Plains through Monday morning. The hazards associated with these thunderstorms are frequent lightning, severe thunderstorm wind gusts, hail, and a few tornadoes. Moreover, the WPC has issued a Moderate Risk (level 3/4) of excessive rainfall over parts of the Northern Mid-Atlantic on Sunday. 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 showers and thunderstorms with heavy rain will continue over parts of the Mid-Atlantic into Southern New England. Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive rainfall with these thunderstorms over parts of the Mid-Atlantic into Southern New England. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, small streams, and low-lying areas the most vulnerable, and landslides on roads. However, the threat of severe thunderstorms has decreased to a Marginal Risk over parts of the Mid-Atlantic and Upper Midwest on Monday as well. Meanwhile, a second front over the Northern High Plains, southwestward into the Great Basin, will move into the Northern Plains and the Great Basin by Monday morning. The boundary will produce showers and thunderstorms over parts of the Northern High Plains, the Northern Intermountain Region, and parts of Washington State on Sunday afternoon into Monday. As the front moves eastward, showers and thunderstorms will continue to develop over parts of the Upper Midwest, Northern Plains, Northern Intermountain Region, and parts of Washington State on Monday. Elsewhere, an influx of moisture over the Great Basin will trigger showers and thunderstorms from late afternoon into the late evening on Sunday, and to a greater extent on Monday. Diurnal heating and ample moisture will trigger showers and thunderstorms from late afternoon into the late evening over parts of the Gulf Coast and into Florida.
