Forecasts suggest the weather could turn more changeable during late July and August but the risk of heatwaves remains.

The UK's weather may turn a little more changeable during the second half of summer with spells of rain featuring in some long-range forecasts. There is also a high chance that temperatures will remain largely above average during late July and August and further heatwaves cannot be ruled out. The season so far has been notable for its heat, with a number of records broken - including some which date back to the notorious summer of 1976. A lack of rain has also been a big part of summer with some places in southern England seeing no measurable rain for more than four weeks. Hosepipe bans are in force for millions of households and dry vegetation has provided fuel for wildfires to burn in a number of areas. 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.
