Britain’s mixed weather is expected to continue with a potential heatwave, torrential rain and thunderstorms forecast.
The Met Office said there was a danger of heavy showers and localised flooding in some parts before the sunshine was forecast to break through early next week as the school summer holidays begin.
It comes after a miniature tornado swept through Greater Manchester at about 5pm on Friday, damaging buildings and cars and leaving debris strewn in its wake.
Mini-tornadoes are known as funnel clouds until they touch the ground and cause damage. There are normally between 30 and 50 a year in Britain.
The latest one hit areas around Manchester airport to the south of the city centre on Friday.
The Met Office posted data from Manchester airport, saying: “Not very often an airport reports a funnel cloud but @manairport’s earlier observation reported ‘FC’ with heavy showers.”
In 2005, one of the strongest tornadoes ever recorded in the UK hit Birmingham, carving a 4-mile path of destruction through the suburbs of the city and leaving 19 people injured.
Heavy rain is expected across western Scotland on Sunday, which may lead to some localised flooding and travel disruption, according to the Met Office. The weather warning for Scotland will remain in place into next week.
For England and Wales temperatures will increase from Sunday with potential for a heatwave and a high of 34C.
Temperatures in London are predicted to peak at 32C on Wednesday, while on Tuesday the mercury could rise to 28C in Manchester, 30C in Bristol, and 29C in Birmingham and Brighton.
Andy Page, the chief meteorologist at the Met Office, said: “As we head into next week temperatures will increase daily across much of England and Wales as hot air is drawn up from France and Spain.
“Temperatures could reach 34C by Wednesday in parts of central, southern or eastern areas and heatwave thresholds are likely to be reached in some places.”
In Scotland and the north-west of England, rain could be heavy later into next week with periods of strong wind bringing a risk of coastal gales.
