Narrative:
There was a strong cold front passing through the area causing very strong winds out of the west-southwest. Aircraft X was north-northwest of ZZZ and was being vectored for an ILS runway 17L descending to 3;000 ft. Aircraft Y was east of ZZZ northbound being vectored for an ILS runway 18R at 3;000 ft. I turned aircraft Y to the northwest and the pilot questioned me about the weather on the runway 18R final approach course because he didn't want to fly through it; so I turned aircraft Y back to the north. I went on to turn aircraft X onto the runway 17L final approach course; but I immediately noticed my transmission had been blocked by the pilot of aircraft Y; complaining about weather. As soon as the pilot of aircraft Y finished talking I immediately turned aircraft X to the southwest and told the pilot to expedite the turn. I climbed aircraft Y and descended aircraft X; all in an effort to prevent a loss of separation. The inability to make all my transmissions in time because the pilot of aircraft Y was complaining about the weather caused me to lose separation between aircraft X and aircraft Y.
