What do they mean?

...When you see meteorologists on your local tv stations forecasting about the weather, you've probably heard them say 'the doppler radar is showing that there is a 40% 'chance' of rain/ thunderstorms'....or something to that effect...

...now, my questions is: what does that 40% mean? That 40% of a certain area, say High Point, North Carolina will get rain/ thunderstorms and 60% of it won't or does the 40% mean that the chance of thundershowers happening during certain time of day is 40%?
