「Chance of rain 2」

The “chance of rain” is actually something that indicates “how many % of a certain area is going to get rain“.

Say you’re overhead a town called A. A has districts from 1 through 10, all equal in size. A’s chance of rain is 80% starting from 5PM, and hearing that, you sort of read in between the lines that you ought to take an umbrella with you when you leave. After 5PM, it will be raining in 80% of A, and in 20% it will not.

That could be districts 1 through 8, or maybe districts 2 through 9. But if you’re inside that remaining 20% area, you won’t get wet in the rain (it also means that if it’s over 0%, rain will always come down without exception). However, they have yet to find a way of determining that area of no rain. I wonder if you get what I mean. Me, I’m a researcher of just that.
