Great Britain is set to experience a surge in temperatures as an Iberian plume brings warm air from Spain towards the UK. Maps from WXCharts indicate that temperatures will reach as high as 23C in some parts of the country, with even northern areas witnessing a rise to 17C. This change in weather conditions follows a cold and snowy April that saw temperatures plummet across the UK. The warm weather is expected to spread across the country, with southern England and southeastern areas particularly at risk due to their proximity to the source of the warm air plume.
