Was at an open day at the Met Office today and this unusual occurrence was discussed at Donna Nook.

A dying storm that fell in on itself and created this 9pm temperature spike of 32.2c.

Just thought I would share this for thoughts, they are checking it out.

Forgot to mention the sudden wind that came as well. Local amateurs commented how strange the sudden warmth was.

It's happened before.  In the downcurrent near the storm, adiabatic heating at the dry lapse rate (3 C / 1000 feet or 1 C / 100 metres).  When the downcurrent hits the ground, the air spreads sideways in the form of wind.

Such events in vicinity of storms must offer the potential for record breaking high temperatures.

What did you think of the place then?

The Met Office you mean?

Impressive building and an interesting afternoon, I could have stayed all week but the doorman wanted to lockup a six I thinks.

Always difficult knowing what level to pitch such events, the majority I would say were retired, in fact the local U3A had a load of people there. But saying that some interesting presentations. Did a bit on climate change and showed the 400,000 year Co2 graph with the massive spike in the the last 50 years. I didn't need convincing, but some seemed to question that it was *their* fault. Of course we are ALL guilty due to our life styles.

Glad I went, just wish I had payed attention at school 40+ years ago.

There was a similar case on Guernsey on 31 July 1983.  A downdraught overshoot.
