While the recent warmth felt across the United Kingdom will last right through the upcoming bank holiday weekend, showers and thunderstorms may dampen some outdoor events.

A broad area of showers and thunderstorms stretching across Spain and France late this week will slowly advance northward into parts of the U.K. this weekend.

“Despite the risk for rain, a warm bank holiday is expected for most of the United Kingdom,” said AccuWeather Meteorologist Tyler Roys.

The warmth may tempt some to plan outdoor events; however, showers and thunderstorms will put outdoor plans in jeopardy across parts of England, Wales and Northern Ireland from Saturday into Monday.

This includes London, Bristol, Manchester, Cardiff and Belfast, where sunshine will be limited by cloud at times throughout the holiday weekend.

While all-day washouts are not expected at this time, a shower or thunderstorm can form and ruin outdoor events with little notice.

Locations from Manchester to Belfast will be at greatest risk for a thunderstorm on Sunday; however, there will be a risk for rainfall each day in London, Plymouth and Cardiff.

Even though these thunderstorms are not expected to be severe, some may produce heavy rainfall and locally strong winds.

Meanwhile, high pressure centered east of Scotland will shield northern parts of the U.K. from any wet weather for the upcoming holiday weekend.

Sunny spells will dominate the upcoming holiday weekend from northern England into Scotland.

High temperatures of 18-22 C (64-72 F) will be common across the U.K. on Saturday, with a few of the warmest locations in the southeast approaching 25 C (77 F). Temperatures will climb a couple of degrees higher across the country on Sunday.

The one exception to the warmth will be locations near the east coast. A wind off the cooler waters will result in lower temperatures with highs near 16 C (60 F) both days.

Widespread warmth is expected on Monday as temperatures soar to 21-25 C (70-77 F) in many locations. A few spots near London that dodge any showers or thunderstorms could have the temperature reach 27 C (80 F).

Beyond the holiday weekend, bouts of showers and thunderstorms are expected to continue across the south for much of next week.

Unseasonable warmth is also expected to continue across the entire country into next weekend.
