Huge Tornado Watch

A tornado watch is out until 9pm EDT for a large part of the Ohio Valley.

Strong thunderstorms are already developing between the Ohio River and Interstate 70 as indicated on AccuWeather radar:

People in the watch should keep up on the weather the rest of the day.

UPDATE 6pm:  While only one damaging tornado so far (red), more than 180 reports of damaging winds and large (≥1") hail. Compare to the outline of the tornado watch. Quite accurate.
