According to the latest weather forecasting maps from the ECMWF model, temperatures across 26 counties in the UK are projected to rise to 20°C and above, with some areas reaching as high as 23°C on April 29. The warmest conditions are expected in the south-east of England and along the south coast, while regions in East Anglia, the Midlands, and parts of Wales will also experience mild weather. Northern Ireland and southern Scotland may see highs of 18°C, with the Scottish Highlands reaching 16°C. However, the Met Office has cautioned that cold air and wintry showers could affect parts of the country, particularly in the north and east. Their outlook from April 22 to May 1 indicates a mix of dry weather and potential rain from Atlantic frontal zones. The forecast for early May suggests that high pressure will dominate, leading to drier conditions in northern and western areas, while southern regions may experience more rain. Overall, temperatures are expected to be around average, with the possibility of late-season frost during chilly nights.
