I really thought that we were going to get it this time ... It was very sunny earlier, then it got very humid and the clouds started to build. It was so dark just now that I needed to put the lights on in the house. I have been watching the display on LightningMaps.org, however, and the storm seems to be about 55 km NW of here at the moment so I think it might just sneak past again.
Perhaps I am a bit slow but I suddenly realised what the expanding, fading circles on the LM display represent - thunderclap wavefronts! I want to see if I hear a bang when the display shows that I should but the storm needs to move closer for that.
