Will,
I was going to say the same thing, but just looking at the BBC Radar. All the rain seems to be "stopping" halfway across the UK, which is strange given the forecasts. Is this due to the High not budging as easily as first thought or some other reason? I'm guessing that this throws the forecast for the rest of the week a little awry. Wokingham still muggy - 28C indoors, very mild but with a slight breeze outdoors (no temp reading).

Ian, Wokingham temps currently (2128Z), Dry 24.6, DP 17.6, RH 65 %.
There is an interesting looking thunderstorm working its way across the Channel from Cherbourg at the moment. -- Bernard Burton Wokingham, Berkshire, UK.

South East - Sandy soils. Seen it all before.
Like a desert here these days ![]() Seriously, usually takes 2 or 3 'goes' after a dry spell before we see any rain here. ---------------------------------------------------------- "Bernard Burton" wrote in message ...

As ever, thoughtful thoughts Will.
What has gone wrong? What factors hasn't materialised, what slight change happened, what was missed, what trigger was thought to be there but wasn't, why wern't these things added to the mix? I suppose if we know that it wouldn't have gone wrong?!
