A weather warning for rain has been issued for Oxfordshire ahead of what is expected to be the hottest day of the year so far.

Temperatures could reach as high as 27C on Sunday, but the recent warm and sunny spell could disappear by the end of the day.

Thunderstorms could strike the west of the country including Oxfordshire with a warning in place between 1pm and 11pm today (May 12).

Heavy rain is likely to bring some transport disruption and possible flooding in a few places.

The Met Office also warns of the possibility of some interruption to power supplies.

It comes as Sunday is expected to be the warmest day of the year so far.

Parts of the UK will be warm and humid in the morning, with temperatures expected to peak at 27C in some places, before the thunder and rain roll in.

Oxford Mail:

Temperatures peaked on Saturday as all four home nations recorded their hottest days of the year so far.

However, Simon Partridge, a meteorologist at the Met Office, said the year-so-far records were “not likely to last long” because forecasters expect it to be even warmer on Sunday.

He added: “The difference (on Sunday) is that it is not likely to be as warm for Northern Ireland, Wales or Scotland.

“The really warm air will probably be confined to southern and eastern parts of England, with temperatures expected to peak in central parts of the country at around 27C.”
