Heavy showers and thunderstorms could impact weekend and Memorial Day plans in Memphis and across the Mid-South. SATURDAY: Showers and storms are most likely in the morning and early afternoon, between 6 a.m. and 2 p.m., and they could be heavy with lightning. Saturday evening and night will be mostly dry.

Memorial Day weekend marks the unofficial start of summer for many in the United States, but it won’t feel like that in the East leading up to the holiday thanks in part to a rare May nor’easter.
