What do you believe weather forecasters mean when they say "40% chance
of rain"?

1) It will rain for 40% of the day.
2) There's a 40% chance it will rain at some point.

I googled it and apparently it depends on the forecaster? 1) and 2) are
completely different meanings.

I think it means 2

Yesterday Accuweather MinuteCast was showing no rain for at least
120mins - I only looked at the site because it was raining and I
hadn't noticed a forecast for it.

Meteox showed no thunderstorms within about 50 miles of us, when we were in a
thunderstorm.

I've seen the Met Office get yesterday's forecast wrong!
