Q: What's the deal with weather forecasts always being 90% chance of precipitation, but it's still sunny outside?

A: Because meteorologists are like the weather equivalent of your aunt, always trying to sell you something you don't need.

*Note: This is not actually true. Meteorologists are actually highly trained professionals who have dedicated their lives to understanding the intricacies of the atmosphere.

Q: Why do weather forecasters always use 'sunny' and 'cloudy' when they mean 'mostly sunny' and 'partly cloudy'?
