It was the storm that preceded the hottest day of the year when the temperature briefly touched 34C in Wanstead – that’s higher than the official recognised figure of 33.5C at Heathrow and Northolt.

Earlier people all around town and across the country wilted in the heatwave waiting for news on the royal sprog, many of them ignorant that things were about to go bang. But no matter – it’s days like this they say is good to bury bad news – so the weather, it seems, decided to get in on the act too. The first spots of rain fell on an exhausted crack Sky News commentary team outside Buckingham Palace just before midnight. About the same time reports started coming in of thunder in Canning Town and Poplar – but all went quiet after three flashes. Then 11.58pm reports of rain in Luke Howard’s old haunt – Plaistow. My own ride back from town saw reasonably heavy, if somewhat shortlived, rain in Southwark. Yet by the time I reached Aldgate the ground was dry. Things began to liven up again at 1.30am – distant rumbles of thunder getting closer – further reports of multiple thunder, lightning and heavy rain with hail mixed in at 1.45am. Then, bang, the storm hit Wanstead. I failed to get any footage of the event because of the ambient light washing out every shot. Multiple crashes of loud thunder followed by, at one point, dazzling lightning flashes. You know how close a storm is by counting the seconds between lightning and peal of thunder. At 1.51am I barely counted to one between a dazzling flash and one of the loudest cracks of thunder I’ve heard. Only 6.5mm of rain was recorded, though this fell at a rate of 60mm/hr – the highest rate since I put the meteo live online last November. It doubled the previous highest rate! There followed frequent, distant rumblings of thunder to the east along with copious flashes and occasional bursts of rain. Epping recorded 19mm in two storms at 5am and 6.30am. The thunder and oppressive humidity made sleep difficult. And judging by the number of bleary eyes on the school run this morning I wasn’t alone. The were other storms around London and the UK – a notable one in Brixton precipitated this account on Brixton Buzz. And Steve Brice managed to capture the lightning in Gillingham, Kent. Pershore in Worcestershire recorded over 56mm of rain in 3 hours while lightning damaged rail networks. It was one of the most dazzling displays I can remember – certainly the best since probably 2000 if not before. People often ask me what first got me interested in the weather. Until last night I’d almost forgotten that thunderstorms were one of the main attractions. A night to remember – just like the overnight storms in the Eighties I remember as a lad.

The 2mb pressure drop, the 60mm/hr rainfall rate, the 2C dive in temperature, and the sudden gust of wind This pressure drop is also reflected in the temperature fall at the same time: 2C in a matter of minutes.
