More than 8 million are under a flood watch for parts of Ohio, Pennsylvania and western New York, including Cleveland and Pittsburgh, where 2 to 4 inches of rain could fall Saturday -- possibly even 2 inches per hour during the heaviest thunderstorms. There is a line of storms expected to form midday over Ohio and then spread east through Pennsylvania for the afternoon and evening, reaching the coast and New York City around 11 p.m. -- but it will likely no longer be severe by then. A Tornado Watch is in effect until 8pm ET for parts of Ohio, Pennsylvania, and a small portion of West Virginia.
