Will there be a heatwave this week and when will the hot weather end?

• The UK Health Security Agency (UKHSA) has issued yellow heat health alerts for the East Midlands, east of England, London, and the South East. These are in effect from 3pm on Wednesday until 8pm on Monday 22 June.
• According to the Met Office , temperatures in the South East could reach heatwave criteria by the weekend.
• “By Friday there is potential for 30C across parts of south-eastern England,” Met Office meteorologist Jonathan Vautrey said. “The exact detail of the temperatures is going to be dependent on cloud amounts”.
• A UKHSA spokesperson said there is “considerable uncertainty for the duration of the very warm conditions” due to “weak weather front moving east into Saturday”.
• They added: “However, there is the potential that the weather front stalls toward the South East allowing very warm or hot conditions to linger across, or near to the far south or South East, perhaps then becoming more extensive again into the following week.”
