The second and fourth one were taken south of greeley. The first and third one were captured in lakewood. I think the first one was a shelf cloud, and there was also pretty nasty green that i did not capture. I think the second one was another shelf cloud, but more organized. The third one was an approaching rain shaft. I think the fourth one was a developing or complete wall cloud. If you guys have any other ideas on what they could be please tell me.
