Issued at: 0500 on Mon 20 Oct 2014

UK forecast for the next 5 days

Breezy with sunshine and showers today. Rain and gales overnight.

Today:

A breezy day across the UK. Fairly cloudy, although there will be some sunny intervals too. Showers feeding into the west, with some reaching eastern parts as well. Wind increases later, with some rain by evening in western Scotland.

Tonight:

Gales developing quite widely as rain moves eastwards across the UK overnight. Some of the rain will be heavy. Rain clearing from the northwest later where it will turn colder.

Tuesday:

Remaining very windy. Rain soon clears leaving the UK with sunny intervals, and also some showers, perhaps with thunder and hail in the north and west. Noticeably colder than recently.

Issued at: 0500 on Mon 20 Oct 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Friday 24 Oct 2014 to Sunday 2 Nov 2014:

Generally cloudy on Friday with rain likely moving northeastwards across many parts of England and Wales and showers, locally heavy, across the northwest. It will be breezy in the north and perhaps the far south. Temperatures will be near or slightly above normal. From the weekend high pressure is likely to gradually build from the southwest, creating a north south split. 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 Monday 3 Nov 2014 to Monday 17 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.
