The meteorological autumn is well underway, but the astronomical season doesn't begin until 23rd September this year. So by that definition, could this record-breaking summer have one last trick up its sleeve? Quite possibly, as it increasingly looks like turning much warmer early next week.

Rain clearing to sunny spells and showers

Patchy outbreaks of rain steadily clear southeastwards by early afternoon. All areas then have bright spells, but there will be showers in the north and west. It will be blustery, particularly in the north.

Temperatures range from 11°C in the north west to 20°C in the south east. Check the weather radar for the most up to date view.

Saturday: Patchy outbreaks of rain affect parts of southern and central Britain. Northern areas have a mix of sunny spells and scattered showers. Windy.

Outlook: High pressure builds northwards, leading to more settled conditions, particularly in southern and central areas. Despite that, some rain is likely at times, especially in the north and west. Temperatures climb and there is the potential for it to become very warm for September.
