system will push slowly across the Ohio Basin, staying mainly south
of the Ohio river. These two systems will combine to bring showers
and some thunderstorms to the region on Monday into Tuesday. Rain is
expected across the entire Ohio Basin, with the heaviest amounts
falling south of the Ohio River.
