THE Met Office has issued a yellow warning for thunderstorms for parts of Scotland and northern England on Sunday from 1pm-9pm.
These could cause localised flooding. Rainfall will “vary significantly, but some locations could see 30-40mm in 1-2 hours”, according to the forecaster.
Some places could see hail that is up to 3cm in diameter along with strong, gusty winds.
The Met Office said: “Whilst there remains some uncertainty in whether thunderstorms develop as cooler conditions follow from the west, there is a chance that an organised line of thunderstorms could develop across northern Britain during Sunday afternoon before clearing east into the North Sea during the evening.
“This is more likely to happen across eastern parts of the warning area including northeast England and eastern Scotland.”
Met Office chief meteorologist Matthew Lehnert described the prospect of thunderstorms developing as “finely balanced”.
He had said: “It’s worth noting the temperatures in the south will remain quite high overnight this weekend, so it’s important to look out for those who may be more vulnerable to heat.”
He added: “There are some marked contrasts in the UK’s weather this weekend, with some potentially impactful thunderstorms developing affecting the northern half of the UK on Sunday, while further south it will become hot.
“For those in the north, there is a chance of thunderstorms developing as we see a change to cooler conditions with a chance that these could become organised with heavy rain, hail, lightning and gusty winds.”
