My thinking based on past few years is we all dont want a cold winter. So it will probably break all records. Snow galore, Ice hanging off rooftops for months on end. Skating on the Thames.
36C at bang on 11am here It was 33C at 11:45. Not that it totally makes a comparison but still reasonable confidence from me that I hit 40C. But let's see.
I am sure if UK public demands this in future it will happen. I can't think the spend would be warranted IMHO. But maybe my view is outdated. I would not be surprised.
