Blowtorch looks primed for next week. Interesting development at this time of the summer.
Ugh, I really hope not, but of course the weather will do what it will. I wouldn't be surprised to see an unpleasantly hot spell, TBH, considering that we had a decent easterly spell just over 3 months ago... these sort of blocky patterns can be stubborn to shift once they're in place. The "European Monsoon" was pretty much a nonevent this year too, which is unusual.
The ECM ensemble shows (for Reading, chosen as it's inland away from coastal grid points) a prolonged period of warm conditions:

These things have a nasty habit of being made warmer as the time approaches and I note, warily, that the 90th percentile is close to the 30C mark by next weekend.
Even the other 90th percentile is above 19C, which suggests a warm spell is pretty much odds-on. Still time for that to change (he says, hopefullly) but I doubt it will.
