I was wondering about that yesterday, reading the local forecast. It
was showing various percentages for each hour, 20%, 30%, 40%, 70%.
Even
threats of thunderstorms. Does the first 20% mean that there is a 20%
risk of some rain within that hour, or something else?

I guess that what it means, perhaps some may think that it means
there's a 20% chance of rain in their lifetime, how anyone would come
to that conclusion escapes me, but there's some on here that think the

Years ago I was outside working on my car when a wagon pulled up to
collect a neighbour's car. The road is narrow and nothing could get
through while is was there. At that point a woman stopped her car
alongside mine, got out and asked if I'd reverse her car for her because
she couldn't do it for the distance required. She looked a bit panicky
when I reversed it at speed for the whole length of the road.
