1 bright reddish/orange glimmering light west of Union City, OK

I was in my back yard looking straight west. I saw a very bright light just above the horizon. I thought at first it was a plane considering we live in a fly zone and within 15 min of a large airport and 5 mins from a small airport. I put my thumb over it and closed one eye thinking the light would move past my thumb, but that never happened. Then I thought we’ll maybe that’s Mars. We live out in the country away from city lights, so we can see a lot of stars and planets. I tried to dismiss it but after a few minutes I started to realize that this was something that didn’t make sense to me. I couldn’t process what I was seeing. I knew it wasn’t a planet, star, or plane because there is an overcast tonight and I can only see clouds. There was only 1 light and it glimmered… sometimes it was slight reddish/orange, then it would be a bright white that flickered. After what I think was 4-5 mins it instantly disappeared. I went inside to tell my wife shortly afterwards. This happened to me 30-35 mins ago.
