Hello Ron,

I'm not commenting on forecast accuracy, merely observations and current satellite imagery.

Fair point on the basis of your local conditions now (though UV levels will be quite high anyway), but there's hardly a cloud in the sky south of a line joining Winchester to the Thames Estuary. If this clear marine air pushes a little further north with the developing sea breeze, then it will become very sunny around London. Or a slight change in wind direction. A delicate balance. There will also be sunny spells further inland.

Cheers Julian

It was mostly sunny here (12 mi S of London) No large Cu. Max 27.3°C
