A marked shift in weather has brought cooler temperatures and morning frosts across the United Kingdom in the first week of May, ending a brief period of unseasonable warmth that saw temperatures reach 25°C in parts of England. The Met Office confirmed that northerly winds and changing pressure systems are driving the cooler, more variable conditions nationwide.

Northern regions began the bank holiday weekend with frost and rainfall as weather fronts moved in, while Northern Ireland saw dry, sunny conditions and England and Wales experienced early fog followed by cloud cover. Showers and isolated thunderstorms were reported in southern areas, with higher temperatures persisting briefly in northern England and Wales due to limited sunshine.

Nighttime temperatures have dropped significantly, particularly in rural and upland areas, raising the risk of ground frost; Scotland and Northern Ireland face the coldest nights under clear skies. Wintry showers are possible over high ground, with Tuesday expected to be cold and foggy with scattered sun and showers in central and northern regions.

Wednesday will likely be the coolest day of the week as stronger northerly winds intensify cold conditions, while a return to milder, southerly airflow on Thursday may bring warmer temperatures despite strong winds and steady rain in Scotland. Scattered showers are expected elsewhere, with neutral pressure patterns limiting broad improvements.

The Met Office indicates a developing low-pressure system over southern UK by the weekend could bring additional rainfall to drier regions, with forecasts to be updated as models refine track and intensity. Daily weather updates will continue via official channels.
