There were some violent thunderstorms at the end of the month. After a wet start an anticyclone gave some warm, sunny days in the second week, but with some night frosts, even in the south of England. The maximum pressure of 1039 mbars made was the highest for June since 1962. There was another short-lived heatwave near the end of the month, with 32.6C in London (Heathrow) on the 19th - the warmest June day there since 1976 (and with an unofficial 34.4C at Kensington). It was very humid, too. Flash-flooding followed very severe thunderstorms that night, with some large hail - in fact the most widespread occurrence of very large (>20mm diameter) since 17 May 1997. There were some high minima too, with a minimum of 20C in London on the night of the 19-20th. There were some severe thunderstorms over the North York Moors on the afternoon of the 19th. Rainfall overall was variable, depending on where the thunderstorms hit. Overall it was quite dry in the south. There were more violent thunderstorms on the 29th, with 35 mm hailstones causing damage in Essex.
