Minecraft, Sleeping Dogs (the rain effects are amazing in SD), DayZ, Terraria. Can't think of any other games for now, but if you want some nice city rain, definitely check out Sleeping Dogs.

Max Payne 2, STALKER series. And it looks like it's going to rain a lot in Arkham Knight.

RPG games like Gothic 3. Provided there's weather change in them.

so far ive seen alot of snowing in borderlands 2 which is rain exposed to certain temperatures, as impressive as it is for immersion i wouldnt mind turning the damn thing off though :)

I haven't played it in years, so maybe my memory is faulty, but there is quite a bit of rain in Knightshift sometimes.

Max Payne 2

GTA IV

Euro Truck Simulator 2, it can rain all day if you want :)

Don't Starve is rainy. As is Cube & Star. Kinda.

Rollercoaster Tycoon :P
