Cloud coverage Humidity Turbidity (2 clean, 10 hazy) Wind (m/s) Rain Snow Coverage spread across the map Precipitation spread

Regional weather (varies across the map) Change over time Allow snow when changing Transition (s) Wind strength Rain and snow (above 1: downpour) Raindrops on the lens Drops on the lens Smallest drop (% of height) Largest drop (% of height) Average state length (s)
