I wasn’t in the UK for these but looking at my vineyard PWS there was an interesting evolution around 12.30-1am:
Temperature rose from 15.2 to 19.4C in 10 minutes, then fell back to 15.2C
Pressure bumped up from 1014hpa to 1017hpa then back down again.
Wind rise from zero to 13mph then zero again, and from SSW to W before going back to SSW
7mm of rain in about 20 mins.
