Exceeded 30C at the Leeds university station, which feels about right. Only 36% humidity though - I’ll never understand people complaining that heatwaves in the UK are humid when they’re usually dry.

Well, firstly they’re not on permanent contracts for gritting. They have other jobs to do too. In the winter they will do both.


 
Secondly, when tarmac starts to melt it can become slippery. Sand will add friction and stabilise the road surface. Whether this is enough in a prolonged period of heat remains to be seen. If the road surface becomes unsafe, the only option is to close the road. Also Inspectors are going round checking the bridge joints too. They have expansion joints to allow for movement, but if this is excessive, the joint will buckle and the bridge will have to be closed.

I’ve had a look through today’s readings and top of the list is the A287 Odiham site in Hampshire with 60.4C at just before 1500 BST. 59C was exceeded at 4 other locations between 1400 and 1500.

And that's with Michelin tyres which are only a couple of months old, too, so no tread worries!


It was quite disconcerting.

Saying it's humid is just a line trotted out by many when they just mean to say it's too hot for comfort.

The potential impacts when you start to think about the bigger picture are catastrophic. I appreciate that us as weather nerds love to push these extremes from a statistical point of view but the prospects of a 40c heatwave lasting even a couple of days are scary.


Emergency planning for the highways infrastructure has begun today. There is a reason why 6 days notice has been given. From a national infrastructure perspective this is not a business as usual heat event.

Have been in 43C in sub-Saharan Africa which I didn't like one bit, but 29C in mist on a Costa Rican hillside was far more agonising, to the extend that I did not enjoy our sighting of a toucan and many exciting insects.

Thought about school closures- and thought again.


Send the children home and the parent/s will have to be home (primary age). 


What will they all do stuck at home on a silly heat day?


You guessed it- charge for the coast.


Even if their own car can cope, many will fail in 35C+ heat. All main roads S will be blocked (believe me, that happens on the first 20 in May on the M3). Ambulances etc will struggle to get through and non AC cars (you might be surprised to know how many of these are still around; equally non-maintained AC units) will get very hot. There will be seriously ill children and older folk possibly, with tens of thousands descending on coastal towns and it could be worse.


So- water pistols welcomed, a few hoses if I can rig them up and a few hundred bottles of free (th the children) water if we can get them before the supermarkets run dry. We have shady woods and well ventilated indoor areas. Also means we know where our vulnerable are.


I just hope the LA doesn't make a silly blanket decision. Doesn't happen in gale or snow, thankfully.

I had to resort to cautioning every train individually before I could give permission to pass the signals. Exhausting after 12 hours of that. Then do it all again for the next 15 days...

A potentially very difficult couple of days coming up. Some of the schools I've worked in are very poorly designed from a heat perspective - think acres of south facing glass and little/ no way of opening them.

Excess deaths from the 1976 heatwave were around 20% above normal. 


Should also add that 32c is very different to 40c
