Temperatures in 28 counties across the UK are projected to exceed 20°C, with some regions reaching 23°C on April 29. The latest forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) indicate that the warmest areas will be in south-east England and along the southern coastline. Milder conditions are also expected in East Anglia, the Midlands, and parts of Wales. Northern Ireland and southern Scotland are predicted to see highs of 18°C, while the Scottish Highlands may reach 16°C. The Met Office reports that high pressure will dominate the weather, leading to dry and sunny spells, although some areas may experience chilly conditions and low cloud. Despite the warmth, there is a warning of possible unseasonable April snow, particularly in northern and eastern regions, as unsettled weather could return over the weekend. Confidence in the exact details of this change remains low.
