UK forecast for the next 5 days

Rain overnight clearing to blustery showers. Gales for many. Colder.

Issued at: 1700 on Mon 20 Oct 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 25 Oct 2014 to Monday 3 Nov 2014:

Early rain across the southeast on Saturday clearing, then showers developing. These are likely to be most frequent in the northwest, where they will be wintry over the high ground. There will be fewer showers further south with some sunny spells developing. Strong winds, especially in the north, and temperatures near normal. This north south split is likely through the following week. There will be generally drier and brighter conditions in the south with a risk of a local frost and fog overnight. More unsettled conditions are likely in the north with outbreaks of rain and a risk of gales which are likely to be interspersed with colder, more showery spells, these possibly turning wintry over Scottish hills at times. The split in conditions will likely continue into November.

UK Outlook for Tuesday 4 Nov 2014 to Tuesday 18 Nov 2014:

The main signal is for a continuation of a north/south split during the first half of November. During this period, the generally westerly flow is likely to bring spells of wet and windy weather, interspersed with drier intervals. These should mostly affect northern and some western areas, but perhaps reaching other areas as well at times. However southern and some eastern areas will probably see more in the way of the drier and settled conditions. These drier intervals will bring some sunshine at times, but also the risk of frost, mist and fog overnight. Daytime temperatures are likely to be near or a little above normal, although feeling cooler during any wet and windy spells.
