C-441 pilot reported prop strike during landing.

Narrative

We had originally filed our flight to ZZZ but due to ceilings and visibility; we diverted to ZZZ1. At the time; ZZZ1 was showing VFR with light winds. We were the final approach for Runway XX after shooting the RNAV XX. We were in moderate precipitation the entire approach. We had broken out about 900 AGL and had a good visual of all the runway lights. We had a stabilized approach and were on approach speed. As we were starting to flair; the aircraft side slipped to the left with the runway lights coming towards the airplane. I added power to go-around and corrected the aircraft back to the runway's center line. The aircraft touched down onto the runway and I cut power and completed the landing. After rolling out onto the taxiway; heavy rain and winds started at the airport; making it difficult to taxi. We proceeded to taxi to the FBO without further incident. Upon shutting down the left engine; we could feel that something was not right with the left engine. We exited the aircraft and saw that 2 of the 5 blades were damaged. No other damage was noted with the aircraft. The next day; the Airport Manager informed us that we had hit one of the runway lights. I can only guess that we hit a gust front. Unfortunately; at night; we did not have any visual cues to anticipate the wind shear. The timing of the wind shear was crucial. A second or two later; I believe we would have been safely on the runway and under control.
