A cold and crisp start, with frost and perhaps fog for a time. A fine day will then follow with plenty of sunshine and light winds. Temperatures will then fall quickly after dusk. Maximum Temperature 9C.

Tonight:

Staying cold and clear over night with light winds leading to a widespread frost, and the risk of freezing fog. However cloudier across the far northwest, and perhaps some rain. Minimum Temperature -3C.

Tuesday:

Another cold start, with any fog slow to clear. Whilst some sunshine is likely for a time, cloud and patchy rain will spread sporadically north during the day. Staying chilly. Maximum Temperature 9C.

Mostly cloudy with outbreaks of rain spreading north Wednesday. These gradually easing on Thursday with variable cloud, but also brighter spells possible during Friday. Turning milder, with winds also strengthening.

Issued at: 0400 on Mon 24 Nov 2014

UK forecast for the next 5 days

Generally fine and sunny. Cloudier with rain across the northwest.

Today:

A cold and crisp start for many, with isolated fog patches clearing. A generally fine and sunny day then follows, however a band of cloud and outbreaks rain will move southeastwards into northwest Scotland and Northern Ireland during the afternoon.

Tonight:

The band of cloud and occasional rain will continue gradually southeastwards, stalling and weakening across southern Scotland and northern England. Elsewhere, cold and frosty, with fog, dense in places.

Tuesday:

Another cold start, with fog patches gradually clearing. A fine but chilly day follows, although some central parts remaining cloudier. Sporadic rain and cloud then spreads north into southern counties.

Mostly cloudy with outbreaks of rain spreading north Wednesday. These becoming largely confined to western parts Thursday afternoon and Friday, with brighter spells elsewhere. Turning milder, with winds gradually strengthening.

Issued at: 0400 on Mon 24 Nov 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Friday 28 Nov 2014 to Sunday 7 Dec 2014:

Outbreaks of rain, locally heavy, and strong winds are likely across the west on Friday and into the weekend. The rain and strong winds will push slowly eastwards through the period with southeastern areas perhaps seeing little rainfall. Southerly winds will reach gale or severe gale force at times in the west/northwest, and draw in milder air than of late; especially by night. The unsettled conditions are likely to persist into the following week. The heaviest rain and strongest winds most likely to affect northwestern areas whilst eastern parts are likely to see the best of the drier interludes. Temperatures will mostly be around normal or milder during spells of cloud and rain, but drier and clearer interludes between weather systems will allow an increased risk of frost and fog.

UK Outlook for Monday 8 Dec 2014 to Monday 22 Dec 2014:

There is no strong signal in weather pattern during this period. However, the most likely scenario is for a continuation of unsettled and, at times, windy weather, especially in western parts of the UK, with eastern parts seeing the best of any dry weather. Temperatures are generally expected to be around, or a little above, average for the time of year. There is a chance of some overnight and morning frost and fog in places - this will be more likely across northern areas where there is also a chance of some snow on higher ground.
