Thunderstorms Sunday from Ohio Valley to Southeast
The area of low pressure associated with a cold front stretching from the Great Lakes southward into east Texas will steadily weaken on Sunday. Winds and shear will also weaken ahead of the front. Moderate to high instability over the Southeast and portions of the Ohio Valley will support at least a marginal risk of strong storms capable of heavy rain, frequent lightning, and damaging winds. Widespread rainfall totals of 1-3 inches with locally higher amounts in excess of 5 inches are expected.
