Yahoo News UK weather: London to see 26C highs before temperatures plummet and Autumn showers arrive
After days of basking in warm weather Brits should brace for Autumn's arrival as temperatures are set to drop by 10C across large parts of the UK.
Sun lovers have been making the most of the balmy weather – which saw temperatures hit 25.4C in Yeovilton, Somerset, on Monday.
However, for most of the country those highs will not last past Tuesday or Wednesday with temperatures eventually dropping to 16C by the end of the week.
Even London and the south east, which started out with warm, dry and sunny weather this week, will be cooler by the weekend.
Operational meteorologist Martin Bowles said: “We are saying there could be a 10C change in the maximum temperature.
“We have had this period of rather summery weather over the last few days – that is going to change on Tuesday and Wednesday, quite significantly.”
It comes as warm air from southern Europe is replaced by cold air from the north Atlantic which should see temperatures drop by Thursday.
The Met Office said it may still reach 26C in some places on Tuesday, including in London, but 16C is set to be the highest temperature anywhere in the country by Thursday.
It is still going to be warm, dry and sunny in parts of the UK on Tuesday – in areas such as south-east England, the Midlands and East Anglia – but cloud is set to build up in the North West.
Large swathes of the country can expect some rain by Wednesday and there will be some reasonably strong winds in the North West, with heavy showers on Thursday.
Mr Bowles said: “There will be a very autumnal feel to the weather which is quite appropriate in a way because Tuesday is the autumnal equinox.
“It is when the astronomical autumn begins so it is quite appropriate we are getting quite a significant change in weather.”
He added: “You would expect a gradual change as we move later in the year, it just happens that as we have got these low pressure systems coming in tomorrow that it coincides with the autumnal equinox.”
In a forecast covering Wednesday to Friday, the Met Office said: “Turning much colder than recently and unsettled with showers and occasional longer spells of rain.
“Some drier, brighter interludes are also likely, especially in the west on Friday.”
