UK weather: Britain to see hottest day of the year as temperatures will exceed 20C

On Friday, a transition to wetter weather will begin, with showers hitting much of the UK as an “unsettled period” hits.

Met Office Deputy Chief Meteorologist Steven Keates said: “While Friday will be another warm day for many, we start to see some wet weather arriving, initially in Cornwall but gradually moving to parts of Wales and central and southern England later in the day.

“This heralds the move to something more unsettled for the UK’s weather on Saturday, with more rain or showers developing for much England, Wales and Northern Ireland through the day, and some heavier bursts likely in places.

“Western parts of Scotland are also likely to see rain on Saturday, with this gradually moving eastwards across the rest of Scotland through the weekend.

“Unsettled weather, with occasional rain or showers for many, will continue on Sunday, with plenty of cloud around as well.”
