UK Outlook for Thursday 4 Sep 2014 to Saturday 13 Sep 2014:

Dry for many Thursday and Friday with variable cloud amounts and some sunny spells once early morning low cloud and mist patches clear. However, northwestern Scotland and the south of England may see some patchy drizzle at times. Temperatures generally above average, particularly across central and southern parts where it could be very warm. However, through the weekend, there is likely to be an increasing risk of rain or showers spreading from the west. Rather changeable conditions are most likely into the following week, with northern and western areas most prone to see some rain at times, whilst southeastern areas will see the best of the drier and bright weather, especially later in the period. Temperatures ranging from near normal in the north to rather warm in the south.

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.
