4 different sets of 10-20 fireballs traveling downward at a slow speed

On my drive home from work I saw what I believed to be a set of meteors falling threw the atmosphere. There was 5 to 10 balls of fire in the sky looking like they were falling. Two to three minutes later I saw another set. I called my wife to ask her if she had seen anything. About 5 minutes later I saw another set, this time it appeared like one was burning up and another would start again at the same location or it was coming out of the same place as the first one. When I got home a few minutes later I went inside to tell my wife, and post on Facebook to see if anyone else had seen it. I went back outside again and saw another set. This time I got photos. 3 different people on our local Facebook page reported that they had seen the same thing.
