UK Bank Holiday Turns Unsettled, Heavy Showers and Thunder Expected

The holiday weekend had already shifted from the warm spell that came before it. After what the Met Office described as a warm start to May, temperatures were set to fall back closer to seasonal averages by Monday, ending the brief run of early-summer conditions that had pushed parts of eastern and southeastern England up to about 25C, with reports of London and East Anglia reaching 27C. The change was a familiar spring pattern: humid air giving way to a colder front, then unstable conditions capable of producing sudden downpours and thunder.

Bank holiday Monday looked like the most unsettled day in the south and centre. The Met Office forecast called for lingering cloud and scattered showers across southern and central areas, while some showers in the southwest could be heavy. Farther north, rain was expected to move slowly across northern Scotland, leaving the rest of the country with a quieter but still mixed picture rather than a clean dry-out.

That split forecast mattered for anyone planning to drive, visit parks or attend outdoor gatherings. The most travel-friendly conditions were likely to be found in areas outside the shower-prone south and southwest, where the rain risk was lower and the main issue was a cooler, cloudier feel. In the places most exposed to the showers, conditions could change quickly, with bright spells interrupted by heavy bursts capable of reducing visibility and making paths, roads and event grounds slippery.
