Several rounds of thunderstorms, some with torrential rainfall, are expected Tuesday and Tuesday night. Several inches of rain may occur by Wednesday morning with training storms. A flash flood watch covers much of the area from Tuesday into Wednesday due to the potential for heavy rain on already saturated soil.
