Watching the Next Rain in the South, Ohio Valley

The storm dragging a zone of heavy snow eastward through the central Plains this weekend will bring drenching rain to portions of the Ohio Valley and southeastern U.S. into early next week.

Dry, sunny weather over much of this area now will be replaced with clouds, rain and localized thunderstorms beginning Saturday night in parts of the Ohio and Tennessee valleys and Sunday into Monday over the southern Atlantic Seaboard.

The rain itself will be locally heavy enough to cause urban flooding problems and blinding downpours.

The saturated state of the ground and streams and rivers running high from the winter could make matters much worse in some areas.

Rainfall will average from 1 to 2 inches in much of this area. On the local level once again, heavier amounts can fall.

Unfortunately, these concerns may be repeated over and over in coming weeks, until the strengthening sun produces substantial evaporation rates.

If you have a stream on your property or you live in a flood plain along a river, you will want to keep one eye on the situation later this weekend, and even through much of the spring.
