Temperatures are set to soar in Lancashire this week, with the mercury predicted to hit 27C in Preston and Blackpool today and tomorrow (September 7-8).

But the Met Office has warned the mini heatwave may come to an abrupt end as forecasters issue a yellow weather warning for thunderstorms.

Following overnight rain, intense showers and thunderstorms are expected to break out in places at around 11am on Thursday morning (September 9).

"Whilst most areas will miss the most intense storms, torrential downpours are possible in a few places," a spokesman for the Met Office said.

"Where these occur, there is potential for 20 to 30mm of rain in less than an hour and up to 40mm in two hours.

"This would have the potential to generate surface water flooding, especially if it falls over an urban area."
