Storm or not storm...

After a lethargic day that was a bit too warm for my taste, these clouds rolled up around 8.00pm.
There was rather a lot of lightning away to the south and the radar showed a tight mass of storm, with very heavy rain, racing towards us... should get here in about half an hour...
Two hours later: nothing. Look at the radar: nothing. Where did it go?!!

Rats - I was really looking forward to a good storm. Oh well, it has cooled down just a tad...


Edit: Pruned a little off the bottom to give more weight to the sky.
