Ahead of bank holiday Monday, thunderstorms could turn severe across much of Wales and England on Sunday.

"Showers and thunderstorms will spread across southern England and into Wales," AccuWeather Meteorologist Tyler Roys said.

Overall, severe thunderstorms will be most likely from the afternoon into the early evening on Sunday.

Thunderstorms will target the South and southern Midlands, as well as much of Wales.

"The area at greatest risk for severe thunderstorms will be in South West England " Roys said.

Thundery showers in this region could produce torrential downpours that could lead to flash flooding, as well as small hail and damaging winds. Wind gusts will likely surpass gale force, topping out near 50-65 mph (80-104 km/h) in the strongest thunderstorms.

Wind gusts of this magnitude are capable for causing broken tree limbs and structural damage, which could lead to power cuts across the region.

Thunderstorms across the rest of southern England, including in London, to southern Wales are more likely to have flash flooding; severe winds and hail reports will likely be more sporadic.

"Overall, thunderstorms on Sunday will be isolated. While one town could get hit, two towns over might end up totally dry," Roys said.

For the bank holiday itself on Monday, thundery showers are expected from Northern Ireland and the central Midlands on southward. Thunderstorms are most likely in the afternoon and early evening, but this time, they are not likely to be severe.

Mild temperatures and sunshine are expected across much of Scotland through the holiday weekend.
