    Me when the weather app says 80% chance of rain, so I go everywhere with an umbrella but it’s overcast all day long. Then it says 15% and I get rained on while walking to the store.

    I’m never going to learn.

      I found out recently that those percentages actually mean 80% of the local AREA would have rain and 20% would not. Meaning if there is a chance of rain in your town at all it’s likely raining somewhere even if it’s just a tiny drop or two.

      So if you don’t want to get wet at all bring an umbrella if the chance is over 0%.

      Source: was talking to a meteorologist about this exact thing.

      Well rain chance is a compound probability it’s the probability that it will or will not rain multiplied by the percent of land hit with rain. Like if 50% of an area will be hit and there’s an 80% chance it will rain the number the weather Channel will give you is 40%
