Bright teal column of light from that came from clouds and touched the ground then disappeared, didn’t go back into clouds.

Driving on the highway south and saw a bright teal column of light come from the clouds and touch the ground from what appeared to be several miles south and slightly west, possibly Belleville, Illinois. It lit up the clouds that it came from bright teal but it was 20 degrees outside and not lightning or a spotlight. Continued to stare in the direction with the other witness and didn’t not see any evidence of a tower or spotlight. It came from above and touched the ground then seemed to disappear and not go back into the clouds. Did not see object in the cloud from which it could have come from.
