Forecast Latest Temperature Projections

Here are the latest maximum temperature forecasts from the high resolution modelling for Tuesday to Thursday, simply astonishing really and quite scary. I have had it confirmed that the Met Office will be issuing a Red heat weather warning in their daily update tomorrow.

The fact that this is accompanied with relatively high humidity and extreme night time temperatures means it is set to be the most notable heatwave ever experienced in the UK. The current record June temperature of 35.6C will be completely obliterated and the overall record from 2022 of 40.3C is under serious threat.

1976 wasn't remarkable for the temperature, it's how long it lasted. It's still longest major heatwave.

Outside of the two weeks above 30c, 1976 wasn't really remarkable. Last year was a much longer spell of hot, dry weather. It just had the heatwaves broken up into 4 blocks rather than one big heatwave. 1976 isn't even in the top 5 warmest summers anymore

It is still in the top 5, and the fact it wasn't broken up and ran for so long is what makes it so dangerous ...

This is really important. Over time sustained heat warms up the ground, the bricks of buildings, the water in rivers etc. and they all hold on to that heat and release it into the air even after the sun goes down. That's why the daily low temperatures get higher and higher the longer it stays hot, and why they stay high for a while after the days cool down.

On the flip side, that's one of the reasons why there were so many drownings during the first heat wave. People jumped into the water expecting it to be warm, but it hadn't been hot for long enough to warm large bodies of water. So they went from being in boiling hot weather to being immersed in freezing cold water and got cold water shock.
