For the third day running, the sea breeze effect has pushed the developing showers inland before they could even put down any rain here, let alone deliver a thunderstorm.
In this way, the marine layer does tend to bring a run of very fine days here whenever there's a gentle flow around a low that's positioned close to the south, southwest or west. Sometimes northwest.
Interestingly, I've noticed that high-resolution models tend to develop showers a little too close to the south coast. I think this is largely down to underestimated surface heating - for example, ARPEGE predicted a high of 19-20°C for Central-Southern England today, but in reality quite a few places have reached 21-22°C.
This in turn is probably down to cloud cover being increased too rapidly during the morning. It's hard to verify that, though, as I can only see total cloud cover views, which include thin high cloud and so just shows 90-100% cloud coverage all day for most of England.
I don't know why it's not routine for model data to omit high cloud from that parameter. It's not useful information for most people!
