Weather: wet, dry, cold, hot, sunny, windy or downright weird - there’s nothing quite like it as a conversation starter, from Austin to Jakarta. And judging from the large volume of emails about all things meteorological in the CrowdScience inbox, there’s plenty to talk about.

What’s the weirdest weather on Earth, and how big a chance is there of it happening? Why does it always seem to rain on the days when we’re not working?
