The flashes through Wednesday morning were incredible! I've never seen anything like it so I assume it was because the Perseid shower occurred at the same time and it was cloudy. We had some mild thunder until it really came overhead about 2 hours later. Before then the ground was rumbling as the sky out up like some mad photographer had a flash going endlessly!
We had more thunder tonight which stuck around for hours and some of that flashing but nothing by comparison.
Good luck catching some more. Our forecast says we have more thunder to come through to at least the end of Thursday. But now you will be renamed Stormchaser James
