ELI5 - Why is some lightning not accompanied by thunder?

We're currently having a great lightning storm in the UK right now, but there is no, or very little, thunder accompanying the lightning. Why is this? It's very eerie!

It is just lightning that is too far away for you to hear the thunder. It takes the right atmospheric conditions for you to see it. It is often called "heat lightning" but there is nothing different about it.
