UK Weather: Temperatures Tumble After Last Week's 25C Peak as Cooler Week Forecast

After last week's warmth, the first full week of May is set to see temperatures tumble across the UK. Temperatures peaked around 25C (77F) in parts of England on Friday, but this week is shaping up to be noticeably cooler. There is a mixed forecast for this May Bank Holiday. Scotland started on a frosty note before a passing weather front is set to bring rain to the far north. But the picture is much brighter elsewhere, feeling springlike and pleasantly warm in the sunshine thanks to the strengthening May sun. Northern Ireland will fare well through the day, staying mostly dry with warm sunny spells. In England and Wales, where the early patchy fog cleared quickly, cloudier skies are expected to dominate into the afternoon. Where the cloud breaks and sunshine develops across northern parts of England and Wales, it should make it feel warmer than Sunday. Further south, however, sunshine will be more limited, and there is a greater chance of lively showers developing, with the possibility of an isolated rumble of thunder. Monday night will feel fresher and ground frost is possible, particularly across Scotland and Northern Ireland. Showers will ease for most, although over the highest Munros any lingering showers may fall as snow. Tuesday will begin on a chilly note, with any early fog soon clearing to leave sunny spells, but also a scattering of showers - most frequent across Scotland, northern England, the Midlands and Wales. Wednesday will have a colder start with patchy ground frost more widespread. It is also likely to be the coolest day of the week as a gentle northerly flow takes hold. This will otherwise be another day with sunny periods and occasional slow‑moving downpours.
