Not sure why Richard's moaning- or anyone else for that matter. If you're looking for records, the real ones might come from the B movies: try thicknesses.
I remember being amazed when most of England was under 570+ in August 2003 and there was a little 576 swathe across the far SE. This produced some extraordinary surface max temps. Now we have 570s up to the Central Lowlands, 576 across all of Wales and Central England, and 580+ across CS England. I know thicknesses are not the only factor in producing those high temps, but they contribute; we have factors in our favour and against.
The antecedent soil conditions are not what they were in the late Spring; much heat could become latent in drying out the ground. Moreover, SSTs are lower, and the Channel crossing will lower surface temperatures, dependant partly on cross-water fetch.
OTOH, the sun's elevation is much higher, and with 850s above 20 and extreme continental heat (although possibly for less time)I'd say game is potentially on for mid 30s. I use that cautiously as the models still have to verify at at least 5 days out.
