I suspect (although as I'm stil a complete novice, this is guesswork based on what's happened in past years rather than great meteorological insight) that the SE of the country probably will scrape 30 degrees C at some stage in the next few weeks. Having said that, I'd be surprised if we got it here (Norfolk), and I would be pretty disappointed - my genetics are Celtic, and us Celts don't cope well in searing weather. I never again want a repeat of July last year when, on a few days away to go to an outdoor concert near Basingstoke we roasted for the entire period, especially in the Travel Inn (near Newbury) at night, in beds with duvets (horrible things!)
Even nearby thunderstorms one night failed to cool things down; the next day it was just as hot as it had been previously. Nearly as bad as 1989 and 1990, which I well remember as a kid being ridiculously hot, and worse, IMO than 1995. We don't realise here in Norfolk how lucky we are to have the sea so close by keeping our maximum temps down a notch compared to the Berkshire area. Give me 20-25 degrees tops and 13-14 at night and I'm a happy bunny.
