UK Outlook for Sunday 28 Aug 2016 to Tuesday 6 Sep 2016:

Sunday looks set to be very warm with some sunshine across England and Wales, but with the risk of heavy and potentially thundery showers breaking out during the day. In contrast, Scotland and Northern Ireland are more likely to be cloudier and cooler with spells of rain. Bank Holiday Monday is expected to be often dry and bright with some sunshine, though still with a scattering of showers around - particularly across northern and eastern areas. For the rest of the period, it looks as if it will be rather changeable, with spells of wet and breezy weather at times. The unsettled conditions probably most dominant in the north, with comparatively more in the way of warm and fine weather for the south.

Updated at: 1244 on Tue 23 Aug 2016

UK Outlook for Wednesday 7 Sep 2016 to Wednesday 21 Sep 2016:

A flow of air from the Atlantic between high pressure to south and low pressure to the north looks the most likely weather pattern at this stage, giving rather changeable conditions. The weather probably most unsettled towards the northwest of the country, and most settled towards the southeast. With this regime, temperatures are expected to be near normal for September, though probably warmer than average at times in the southeast.
