UK forecast for the next 5 days

Rain sinking south and weakening. Largely fine elsewhere.

Today:

A band of rain across some northern and western areas will move southeastwards but will weaken. Turning brighter behind but breezy and showery into the northwest. Fine and warm ahead of the rainband but cooler than of late.

Tonight:

Generally dry and clear with mostly light winds leading to a cool night in places with local mist or fog patches. Breezier into the far northwest with showers later.

Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 4 Sep 2016 to Tuesday 13 Sep 2016:

Unsettled on Sunday, with showers or longer spells of rain, but also drier, brighter spells. It'll remain unsettled into the start of the week across northern parts, with showers or rain and stronger winds, whereas it should become largely drier in the south. Perhaps a longer, dry, settled spell developing more widely next week. Otherwise, this changeable weather is more likely to continue with showers or longer spells of rain, interspersed with drier and brighter conditions. The wettest and windiest weather is likely across the northwest and the driest and sunniest conditions in the south, though even here there is a low risk of thunder at times. Temperatures should be near or above normal, with warm spells in the south and east and rather cool in the northwest at times.

UK Outlook for Wednesday 14 Sep 2016 to Wednesday 28 Sep 2016:

Confidence remains low in the forecast for this period, however the most probable scenario is for the changeable weather to continue at first. This will bring showers or outbreaks of rain to some, these interspersed with drier and brighter interludes. The heaviest rain and stronger winds are likely in the northwest, with the drier conditions and lighter winds in the southeast. A trend towards more widespread drier, settled conditions looks possible for the second half of September. Temperatures are likely to average out above normal.
