The states of Ohio, Kentucky, Illinois are looking at as very dangerous and, thankfully, very rare weather situation tonight and tomorrow. Forecasters are warning of severe weather for the region including a possible derecho, for the area. Derechos are lines of severe weather that bulge out into a bowing segment that can extend several hundred miles as the figure below demonstrates (this is an example, not a current weather radar)
So it is imperative that persons living within these states keep abreast of local conditions WELL IN ADVANCE to the arrival of such a vicious storm. Make sure to listen to local media for watches and warnings and breaking weather news.
It is best to have a battery operated radio that you can trust when the power goes out. And please, make sure you have fresh batteries! Or better yet, get yourself a crank radio like the ones advertised below.
