Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 22 Oct 2017 to Tuesday 31 Oct 2017:

Next Sunday will likely see an unsettled start, with wet weather clearing to the east, leaving a mix of sunshine and blustery showers for the rest of the day. The following week looks set to remain unsettled, with further periods of wet and windy weather, especially in the north and west. However, it is possible that there will be some longer spells of drier and brighter weather in between, most likely across the southeast. This may lead to more settled conditions towards the end of the month, although there remains some uncertainty. Temperatures will vary around normal through Sunday and Monday, before becoming slightly warmer through the rest of next week. There is an increased risk of chilly nights in any more settled spells.

UK Outlook for Wednesday 1 Nov 2017 to Wednesday 15 Nov 2017:

As we head into the start in November, a changeable pattern is most likely at first bringing spells of wet and windy weather, interspersed with some drier and brighter interludes. The most unsettled weather is likely across the north and west, with the south and east often drier and brighter. These drier conditions may become more prolonged as we head through the first week of November, bringing an increased chance of frost and fog overnight. However, the northwest may remain more unsettled, leading to a more general northwest/southeast split by mid month, with the wettest and windiest weather in the northwest. Temperatures are likely to stay close to normal, although it may be colder than normal where settled spells are prolonged.
