Hello Peter
Thanjs for the links there. They are computer generated forecasts based on the GFS extended model output. They are fairly useful as a rough guide but their accuracy beyond 5 days is questionable. Having said that, in regions such as the Med (at this time of year) patterns are generally quite static and longer-term outlooks are slightly easier to predict. The data I have used in my prediction of extreme heat is somewhat more extensive and I suggest that the Accuweather forecast of around +28 to +31 next week is very conservative. I hope I'm wrong as I hate the very hot stuff.

It is beyond anyone's range to go further than 10 days and any forecast you see is pure guesswork. However, going by historical means it would be reasonable to suggest any very hot weather will be temporary and it should return to the high 20s before long. As for storms - well, I hope we get one or two as I love a good thunderstorm (at night that is!)
