Britons have been warned to prepare for a double-digit drop in temperatures from Monday, with the balmy conditions on the hottest day of the year so far giving way to considerably cooler climes.Highs of 25.5C (77.9F) in Cambridge on Sunday set a new record for 2017, comfortably eclipsing the 22.1C recorded last month, as sun lovers were lured to parks and beaches in droves.But those expecting Sunday’s weather to be an indication of the early onset of summer are likely to be brought back down to earth with a bump – with temperatures plummeting by at least 10C (50F) this week. Greg Dewhurst, senior forecaster with the Met Office, said: “Sunday was the hottest day of the year so far, and in fact several places recorded highs of at least 25C – in Lincolnshire, St James’s Park in London, Kew Gardens and Heathrow, for example.”But this week will feel much more like normal for the time of year. We are looking at temperatures of around 14C – that’s 10C lower than on Sunday.”There will be some cooler west to north-westerly winds, which will also help bring the temperature down.” It was very warm once again yesterday, with plenty of sunshine. However, cooler and cloudier weather slowly moved in from the north and west pic.twitter.com/09OIRiFlU5— Met Office (@metoffice) April 9, 2017v And he said early signs showed more of the same for the Easter Bank Holiday weekend. Mr Dewhurst said: “It looks like there will be a mixture of showers and some sunny spells over the weekend. “In the sun it won’t be too bad, but it will generally feel much cooler than the weekend many of us have just had.” UK weather forecast: Monday, April 10 Want the best of The Telegraph direct to your email and WhatsApp?
