Narrative:
Heavy to extreme weather was moving east along the runway xx final at ZZZ. I descended the MU30 to 1600 feet; the MVA nearest the aircraft. I vectored the aircraft to a 330 heading then a 350 heading. The pilot advised that he wanted to weave in and out of some build ups. I said approved. When the aircraft was getting close to an MVA I told the pilot the MVA altitude was 2700 and pointed out the obstructions. I asked a fellow controller in the room if I could fly through the MVA while I was not vectoring the aircraft. He said just tell him to maintain visual separation from the obstructions. So I did that; the aircraft read it back and then he proceeded to fly into the western side of the MVA as he was moving around the storms. Low altitude never went off. If the pilot needs to deviate; then climb to the MVA altitude. Check with a flm rather then another cpc. Vector aircraft away from the MVA if too close.
