Heat lightning is lightning that is very far away, but conditions like overcast let you see the flash over great distances, up to 100 miles away. It makes thunder, but sound doesn’t carry anywhere near as far as light so you can’t hear it. But anyone who was nearby to the actual lightning strike would’ve heard thunder.

Edit: Oh, and it doesn’t actually have anything to do with heat. The name’s a misnomer.
