Outlook for the UK over the next 6-30 days

UK Outlook for Thursday 3 Sep 2015 to Saturday 12 Sep 2015:

The gradual change to more settled conditions across the UK continues with plenty of dry and bright weather across much of the UK through the weekend, however there will still be the odd shower around at first, especially towards the southeast. The mostly fine and dry weather is expected to continue through until the middle of September, however there is a risk that more unsettled conditions, with further spells of rain, could push into northwestern parts early next week. Temperatures on the whole will be slightly below average, although it will feel pleasantly warm in the sunny spells and light winds. Overnight temperatures throughout the period are likely to be on the chilly side, with a risk of localised rural frost and fog patches, mainly in the north.

UK Outlook for Sunday 13 Sep 2015 to Sunday 27 Sep 2015:

The generally settled and fine conditions are expected to continue across Southeastern parts of the UK through much of September, with plenty of dry and sunny weather, and only a low risk of short lived spells of cloud and rain. In contrast it is likely to remain on the unsettled side in the Northwest for the majority of the month, with occasional bouts of rain and strong winds likely. Temperatures will generally be around average in most parts, but feeling warm under any prolonged sunny periods in the Southeast by day, with some chilly nights in the North.
