As the weekend draws to a close, the UK is expected to experience a significant drop in temperatures, attributed to incoming Arctic air. Forecasts suggest maximum temperatures will hover between 3-8 Celsius, with widespread ground frost anticipated on Monday morning. While this weather system promises some sunshine after weeks of gloom, the potential for snow remains uncertain. Residents in Scotland and northern England may see wintry showers, particularly in mountainous areas, but the exact snowfall amounts will become clearer in the days ahead.
