The Toledo ANG Base is about three hours from Cleveland by convoy, so I don't think support to Cleveland is the reason. As far as the base being on the alert, they may have raised the terrorist threat level for some reason they are not saying - Toledo flies F-16s and is responsible for air defense of the Davis-Besse Nuclear Power Plant, among other things. Close air support for urban police departments isn't one of them. These threat levels change frequently based on current intel, and are generally on a need to know basis, like you work there.
