UK weather forecast latest: Temperatures set to soar to 20C after forecasters issue severe fog warning

Parts of Britain woke up to a blanket of thick fog on Saturday with temperatures set to soar to almost 20C later in the day.

A severe yellow weather warning was issued across southern England, with forecasters warning that dense fog could cause travel disruption.

The fog is set to lift by lunchtime, making way for glorious sunshine and another exceptionally warm day ahead.

The mercury is set to stay in the mid-teens into next week, with tomorrow’s fog expected to be less severe.

Many flights were delayed on Saturday morning because of the fog.

Planes were unable to land at City Airport, with flights also delayed at Gatwick and Heathrow.

Met Office meteorologist Marco Petagan said: “This morning the fog will be clearing and the south east will get the best of the sunshine.

“There might be some rain across Northern Ireland and western Scotland, which could sink to east Cumbria and west Wales.

“It’s another very mild day to come, with temperatures in the mid-teens and 15-17C as a high.

“The north of Wales will be the warmest while the Moray coast in Scotland will also do well.

“Tonight there is a chance of the fog reforming, particularly in east Wales and the Midlands. There could be the odd patch elsewhere, but we’re not expecting warnings at this stage.

“There’s a chance of the odd pocket of frost, with temperatures falling to single figures.

“Tomorrow any fog will be lifting, with another lovely day for most, and Scotland and Northern Ireland will be brighter than today.

“It’ll be a generally dry day, with temperatures of 15-16C, and that won’t change a lot into the start of next week.

“There’s a chance of mist and fog in the mornings, but it’ll be fine and settled with temperatures in the mid-teens.”
