It wasn't a low level weather abort. It was a toss bomb attack on a laser-designated simulated target which went wrong because the aircraft entered cloud on the pull-up and the pilot apparently became disoriented, exiting the cloud in a nose-low attitude with insufficient time to recover. Ejection was initiated from the WSO's seat but too late. Callsign was Deuce 31, not Badger 21.
Cloudbase was reported by his wingman, Deuce 32, as 2700ft amsl (c.1800ft agl) at the time of the accident.
