Aircraft X called me as a pop up going VFR. I issued squawk code and within a few sweeps he was inside of Class B airspace. I called ZZZ for the point out. Pilot became disoriented due to low clouds and was getting closer to the Runway XX final at ZZZ. I was able to guide him out of the Class Bravo airspace. At one point the pilot got down to Mode C readout of 200 FT and I issued a low altitude alert fearing that he was just continuing down until the clouds were gone. I got the latest ASOS reading for [nearby airport] and told the pilot that area had better weather at 1;100 FT ceilings. The pilot stated he was in the clouds but could see through the top. I gave him a safe heading range for the climb because he asked for a vector. I asked if he could see the bridge to the right and he said yes I said to follow the bridge then pilot said he wanted to get on top of the clouds and I suggested; based on my knowledge of the area weather patterns to head down the bay toward [the southeast] but the pilot continued NE bound and said he could see the tops. Once on top I had the pilot resume own navigation. I believe that I forgot to say the pilot was RADAR identified; although I observed him squawk the code I assigned and pilot's initial position report was correlated. I do not recall if he gave me the altitude. I was more concerned with getting him away from the ZZZ arrival and safely though the weather he was encountering. I could have told the pilot on initial contact what the latest PIREP for cloud base and tops were at ZZZ1. I wasn't sure if he was on top or below or in the clear when he called.
