“Looking ahead, from August 5, mixed conditions are most likely looking, with no specific weather conditions.
“It is likely that from that date, there will be a period of some drought and some showers and rains.
“But as we move toward mid-August, it is likely that more settled and drier conditions will develop.”
Mr Dixon cautioned that the accuracy of the forecasts so far was not guaranteed in the future, but said it looked like warm and drier conditions would develop over much of the UK.
“This does not translate into a specific prediction of another heatwave, but it is possible that warmer conditions will develop,” he said. “It looks like it will be warmer than the average for the month.
“The average for the whole UK is 19C, so warmer than average could mean lower 20s. This is looking like above average for mid-August in terms of temperatures, but obviously over that long range the forecast is higher. Is uncertain.
