It would also be the second time this summer Montgomery had a top-three rainfall streak, following a stretch of nine straight days with rain in July.

Tuesday and Wednesday will bring additional rounds of showers and thunderstorms to many of these same areas. A cold front will finally move through the South Wednesday into Wednesday night, ushering in a drier air mass for the end of the workweek.
