UK forecast for the next 5 days

Fine with sunny spells, but rain for the north-west later.

Outlook for the UK over the next 6-30 days

UK Outlook for Friday 2 Sep 2016 to Sunday 11 Sep 2016:

Outbreaks of rain in the northwest, occasionally heavy, will move erratically east or southeast on Friday and Saturday, weakening as it does so. This will clear to brighter, but showery conditions with the showers most frequent in the northwest. Thereafter there is some uncertainty, however it is most likely to remain changeable, with showers or longer spells of rain, interspersed with drier and brighter conditions. The wettest and windiest weather is likely across the northwest with the driest and sunniest conditions in the southeast, though even here there is a low risk of thundery showers at times. Temperatures will generally be near or a little above normal, with warmer spells in the east at times.

UK Outlook for Monday 12 Sep 2016 to Monday 26 Sep 2016:

Confidence remains low in the forecast for this period, however the most likely scenario is for the changeable, and at times rather unsettled, weather to continue, at least through the start of this period. This will bring showers or outbreaks of rain, 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 drier and more settled conditions looks possible during the second half of September. Temperatures are likely to be above normal.
