It is much quieter across northeastern this morning, following last night's severe weather outbreak. It should remain quiet through the morning hours with partly cloudy skies expected.
This afternoon, the atmosphere will destabilize once again, ahead of an approaching cold front. Scattered thunderstorms will erupt this afternoon and continue through tonight. Very heavy rainfall is possible, and a flash flood watch has been issued for most of northeastern Ohio. In addition to the flood threat, some of the storms could become severe with damaging winds and hail possible.
The cold front will slip to the south of the area late tonight or early Wednesday. We may see a break in the rainfall Wednesday morning, then showers and thunderstorms are expected to redevelop Wednesday afternoon as an intensifying area of low pressure moves toward the state from the southwest.
Rain, heavy at times, is expected across the region Wednesday night through Thursday as the low deepens and tracks northward across the state. Rainfall amounts from today through Thursday could exceed 2 inches across much of the area.
