Brits have been told to prepare for “turbulent” weather as heavy showers and strong winds are due to sweep across the country.
Warmer spots in the south east of England saw highs of 21C on Tuesday but the sunshine is due to give way for more unsettled weather for the rest of this week.
A severe weather warning for downpours is set to come into force, with the possibility of some localised flooding in the wettest locations.
Met Office meteorologist Steven Keates told the Evening Standard: “We’re entering a much more unsettled and turbulent spell of weather with many places seeing heavy rain and also some strong winds as well.
“On Wednesday morning, particularly in eastern areas of the UK, it will start off fine and dry.
“It might be a touch on the chilly side, as further west we’ve already got cloud and some heavy rain coming in from the Atlantic.”
The Met Office has issued a weather warning for rain across south west Scotland for the morning as the wettest spots might see a couple of inches of rain which could cause some localised flooding.
“Through the day tomorrow, a band of rain will be working its way further east and by dusk it will reach East Anglia and the far south east of England,” said Mr Keates.
Temperatures are set to reach highs of 16C to 17C in the southeast on Wednesday.
The rain is then set to clear out into the north sea by the evening, but it will linger across the northeast of Scotland.
Mr Keates added: “Things turn more unsettled still as we move through Friday into the weekend. We’ve got a very strong jet stream coming across the Atlantic coming our way.
