Weather maps indicate a significant warm spell is on the horizon for the UK, with temperatures potentially reaching 26C in parts of England. The GFS weather model shows that 74 counties across England, Scotland, and Wales will see temperatures of 20C or above from May 4 to May 6.
On May 4, temperatures are expected to climb to 21C and 22C across southern and central England, with North Wales also reaching 21C. The mercury will continue to rise, with London and the south-east hitting 24C on May 5. Scotland may see 20C, while Wales could reach 23C.
The warmest day is forecast to be May 6, with highs of 26C in and around London. The Midlands, Yorkshire, and East Anglia could experience 24C or 25C. However, Northern Ireland and Scotland will be cooler, with Northern Ireland only reaching 19C.
Despite the heat, this spell is not expected to constitute an official heatwave, which requires temperatures to meet or exceed the threshold for three consecutive days. The threshold varies from 25C to 28C across the UK, with the highest in the south-east.
