Not challenging your knowledge. Just adding color for the thread.I know it’s in OC ( I’m in OC) and the weather was cloudy/ foggy all day. A Google search says the closest airport to the crash site is Van Nuys Airport and they reported the weather was at IFR during the time of the accident. Camarillo Airport to the north reported MVFR so it’s safe to say the weather at the time of the accident was MVFR at best.
