Drenching rain may lead to new flooding and aggravate existing flooding over the Ohio, Tennessee and lower Mississippi valleys as well as parts of the southern Appalachians and the Carolina coast.
A few downpours will dot the Gulf coast.
While much of the Plains will be dry, a new storm will spread cold rain along the coast and snow over the inland areas of the Northwest.
