We face a likely chance for storms on your Memorial Day. The heaviest rain will fall over northwestern Alabama where storms have been ongoing this morning. A few strong storms are possible especially over the Shoals and into southern Tennessee.
Through midday, most along and east of I-65 will avoid any heavy rain. Storms will be approaching, though, heading into the afternoon.
For the early afternoon, storms will be winding down over the Shoals. They should be fairly widespread along I-65 and moving into northeastern Alabama. Heavy rain and frequent lightning can be expected. The more intense storms will produce damaging wind gusts.
By this evening, the widespread rain and storm threat will begin shifting out of the Valley. We should stay relatively quiet overnight, but storms are likely once again on Tuesday.
For Wednesday and the rest of the week, we shift into more of our typical summer time pattern. That means it will be warm and muggy with pop-up afternoon storms.
