From what I can tell, there's at least 2 different variables that affect the range of temperatures that any given climate type will generate. It will snow if the temperature reaches a certain low temperature. Normally, the Mediterranean climate won't reach that low temperature, but it looks like you got the fluke case where the two different variables coincidentally both decided to be extra low at the same time and hit the magic threshold for snow. It shouldn't happen regularly.
