Frank Saunders, Chief Meteorologist at the Met Office, said: “After weeks of predominantly high temperatures and very little rainfall for many parts of the country, high pressure is finally breaking down allowing a cold front to introduce cooler, fresher air from the Atlantic to all parts of the UK.
“Temperatures will still often be in the low to mid-20s Celsius in eastern parts of England for the rest of this week, which although is above average for the time of year, will be notably cooler than recent weeks.
“Elsewhere, temperatures in Scotland, Northern Ireland, Wales and western England will be closer to average, the high teens being typical.”
