Outlook for the UK over the next 6-30 days

UK Outlook for Thursday 26 Oct 2017 to Saturday 4 Nov 2017:

The north and northwest will be cloudy and windy on Thursday with rain at times, and rain may affect other western areas for a time on Friday. Elsewhere it will be a mostly dry end to the week, with southern and southeastern parts seeing the best of any sunshine, although some stubborn overnight fog patches are also possible here. Temperatures will generally be above average and it could become very warm in these sunnier areas. Thereafter the weather is generally expected to become less settled. The north and northwest should see the wettest and windiest of the weather though, with some drier spells expected to develop towards the southeast. Temperatures are most likely to start above normal, although could trend downwards through the period.

UK Outlook for Sunday 5 Nov 2017 to Sunday 19 Nov 2017:

There is an increasing chance that the weather will become more settled during this period, especially across southern parts of the British Isles. As a result frost and fog could become more likely. The north may continue to have more unsettled conditions though. Temperatures are most likely to be near or slightly above average, although probably below normal in some of the more settled spells, especially where any overnight fog proves slow to clear.
