UK weather: More heatwaves possible in second half of summer

Current trends suggest a chance of more changeable weather during the second half of summer.

However, the signals from computer weather models are rather mixed meaning there is a lot of uncertainty.

The latest sub-seasonal forecast from DTN – the BBC’s weather data supplier – suggests that areas of low pressure will feature more prominently over the next couple of weeks, especially for Scotland and Northern Ireland.

This would mean an increase in wet weather.

However the Azores high, a semi-permanent large area of high pressure over the North Atlantic which can block weather fronts from reaching the UK, is likely to be close by. This will keep things drier further south, although not necessarily completely so.

Temperatures are most likely to remain above the seasonal norm, especially in England and Wales where further hot spells or heatwaves are possible into early August.
