Oh, Azazel, unfortunately I don't agree with your statement, there is no such thing as "We've seen this so many times in recent summers". It doesn't matter what Summer we're in, it's just that recently parameters have not been good enough to sustain MCS development over the UK, nothing to do with the year, it's to do with that. I have good confidence that at least thunderstorms with a certain degree of MCS development will move across Kent this evening, there's already thunderstorms in France so will be quite interesting to see what happens later.
