Human Factors; Weather
I was PIC of a Piper Cherokee landing at ZZZ. Weather was VMC and I was number three on arrival for XXR and looking for Citation traffic inbound. About 3/4 of a mile abeam the numbers; ZZZ Tower instructed me to make an immediate right base; and to switch to a cleared XXR landing; the parallel runway; for traffic (one Citation had just landed; another on the way in). I complied; responded to ATC; and began an immediate descent to avoid too high of a final approach onto XXL.I came in to land on XXL as normal. Just before touchdown; I felt a crosswind gust on the starboard side and felt the aircraft nose point to the right; so I applied left rudder to keep the nose straight. At this point the aircraft touched down; the nosewheel also then touched down and the aircraft began to slide to the left. I attempted to return rudder/nosewheel input to neutral but the aircraft began to skid to the left. This caused the aircraft to turn 45 degrees left of runway XXL centerline.The aircraft then entered the grass area left of XXL; cut across an intersecting taxiway (what I believe was taxiway  E); the right wing root impacted a taxiway location sign; the aircraft then went from the grass onto the taxiway B surface; I then applied rudder pedals to put the aircraft onto the taxiway centerline; and applied full braking power.I do not recall the time between the first jet landing on parallel XXR and my aircraft touching down on XXL; but it was within two minutes. The second Citation landing on parallel XXR was behind my aircraft at all times so I do not believe the second aircraft wake turbulence was a factor.I do not know if I could have avoided this accident with a go around. I remember thinking the landing was a particularly smooth one very briefly; under the nose wheel touched down and the aircraft began veering to the left. I attempted to bring it back to centerline but was afraid that too much right rudder would cause it to skid the other direction. Once I entered the grass; I recall trying to put all control surfaces to their neutral position until the aircraft returned to the tarmac that was taxiway B.
PA-28 pilot reported a loss of control on landing that resulted in a runway excursion.
