Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 21 Sep 2014 to Tuesday 30 Sep 2014:

Sunday should be mostly fine with sunny spells, although still with the risk of showers in the south, while thickening cloud in the far northwest may bring some light rain later. It is then likely to remain largely settled into early next week, especially in the south, but a little cooler than preceding days, whilst outbreaks of rain alternate with sunshine further north. Later in the week, these more unsettled conditions are likely to spread southeastwards, bringing an increasing risk of spells of rain to much of the UK, but always heaviest towards the north and west. Winds mostly light across the south, but stronger in the northwest, with an increasing risk of gales. Temperatures generally around or somewhat above average, perhaps still warm at times in the southeast.

UK Outlook for Wednesday 1 Oct 2014 to Wednesday 15 Oct 2014:

The first half of October is likely to see more changeable conditions across the UK, with a mixture of fine and settled weather, interspersed with occasional unsettled spells. The drier and brighter conditions, with some warm sunshine, is then expected to be most prolonged across the south and east, whilst outbreaks of rain would then be most frequent across the north and west. During the more settled conditions daytime temperatures are likely to be around, and often above, average although it could turn quite chilly overnight with a risk of fog patches in places. However during any more unsettled spells, daytime temperatures are then likely to be below or close to average.
