Temperatures are expected to rise above 20C in up to 26 UK counties based on the most recent weather forecasting maps. The ECMWF model suggests that a heat surge is on the horizon for Britons later this month, with some areas potentially reaching temperatures as high as 23C.

According to the data, the peak temperatures are anticipated in the south-east of England and along the south coast on April 29 around 6pm. Additionally, warm conditions are forecasted in East Anglia, the Midlands, and parts of Wales. Even regions further north are expected to experience relatively mild temperatures, with Northern Ireland and southern Scotland possibly reaching highs of 18C and the Scottish Highlands around 16C.

The real warmth is predicted to be concentrated in the southern regions, as reported by the Express. The maps highlight that 28 counties could witness temperatures exceeding 20C on April 29. However, the Met Office has cautioned that some parts of the country may encounter cold air and wintry showers during this period.

Looking ahead, the Met Office’s outlook from April 22 to May 1 suggests that dry weather is likely, with some exceptions. Cold air and potential wintry showers may affect the north and east of the UK, followed by a short-lived cold spell before milder conditions return. The outlook for the start of May indicates that weather patterns are expected to continue evolving, with high pressure most likely situated to the north or northwest of the country.

During the first half of May, temperatures are projected to be close to or slightly above average, with the possibility of chilly nights and late-season frost, particularly in the north.
