Temperatures are expected to rise above 20C in up to 26 counties across the UK based on the latest weather forecasts. The ECMWF weather model indicates a potential heat surge later this month, with some regions reaching as high as 23C. The peak temperatures are forecasted for April 29, primarily in the south-east of England and along the south coast around 6 pm. Additionally, warm conditions are anticipated in East Anglia, the Midlands, and parts of Wales.
Northern regions are not expected to be significantly colder either, with Northern Ireland and southern parts of Scotland potentially reaching highs of 18C and the Scottish Highlands around 16C. However, the real warmth is predicted to be felt in southern regions, with 28 counties likely to experience temperatures of 20C or above on April 29.
Despite the warmth, the Met Office has warned of possible cold air and wintry showers moving through some parts of the country. The weather outlook from April 22 to May 1 suggests a fair amount of dry weather overall, with exceptions such as rain and breezy conditions in the southwest due to Atlantic frontal zones. Towards the end of April, a brief cold spell may bring wintry showers to the north and east, followed by milder conditions.
Looking ahead to the start of May, the Met Office forecasts a continuation of slowly evolving weather patterns. During the period from May 2 to May 18, high pressure is likely to dominate in the north or northwest, while low pressure may affect southern regions. This setup could result in drier conditions in the north and west, with more rain or showers expected in the south and possibly the east. Overall, temperatures are projected to be close to or slightly above average, with the potential for chilly nights and late-season frost, especially in the north.
