This was just downloaded from the Missouri State Park webpage. I am not sure how the recent thunderstorms will affect this, but I know the rains haven't been statewide so I am sure it is still in effect in some areas.
...Due to dry and excessively hot weather, Missouri State Parks has issued an OPEN FIRE BAN on all state parks and historic sites. The open fire ban includes prohibiting campfires and other open fires. Contained charcoal fires used for cooking as well as gas and cook top stoves are allowed under the open fire ban.
