Lucked out...

The weather forecaster on the BBC last night said if we were looking forward to sunshine today, we had lucked out.

But what exactly did he mean?

Have you ever lucked out? Well, good for you. Or not. Depending on where in the world you live.

to luck out
(Colloquial, idiomatic, informal: US, Canada) To experience great luck; to be extremely fortunate or lucky.
"I lucked out, and got the last two tickets to the big show."

to luck out
(Colloquial, idiomatic, informal: Britain, Australia) To be unfortunate or unlucky; to run out of luck.
"I lucked out, and didn't get the last two tickets to the big show."

And sure enough, the BBC forecaster was right. We had lucked out. It rained today round our way.
