UK Outlook for Tuesday 2 Sep 2014 to Thursday 11 Sep 2014:

Dry for many on Tuesday and Wednesday with sunny spells. However, thicker cloud across northern parts may bring some showery outbreaks of light rain here. The settled conditions will likely extend north from Thursday and into the weekend with sunny periods and light winds. However, the far northwest may see some patchy light rain and drizzle at times. Temperatures are likely to be above average, particularly across southern parts where it could be very warm. Into the following week, the settled conditions may give way to a return of more changeable conditions, with northern and western areas most prone to see some rain at times, whilst southeastern areas are likely to remain mostly dry. Temperatures will be close to average in the northwest, but remain above in the southeast.

UK Outlook for Friday 12 Sep 2014 to Friday 26 Sep 2014:

During mid to late September most regions can expect to see periods of fine weather, with some warm sunshine at times. However, these fine periods may well be interspersed with occasional spells of cloudier, more unsettled conditions bringing showers or longer spells of rain. Northern and western parts are probably most likely to see the more frequent bouts of unsettled weather, whilst southern and eastern parts should see the better fine and dry spells. Daytime temperatures are likely to be above average during fine weather leaving conditions feeling pleasantly warm. Nights, however, may well be on the chilly side. During any unsettled weather daytime temperatures are more likely to be near or below average leaving conditions feeling cool.
