The Met Office expects temperatures to rise from Monday (August 9) and reach 30C by Tuesday and 31C on Wednesday. Clear skies are expected on Tuesday and Wednesday turning to clouds and highs of 23C-26C at the end of next week. It comes as a yellow heat health alert was issued for York on Saturday until Tuesday. East Anglia and south-east England, however, could see temperatures even higher on Thursday. Nineteen counties across England recorded effectively no rainfall – 1mm or less – across the whole of the month, Met Office figures show.
