    Regional forecast for Wales

    Frosty in the east, rain later north and west.

    This Evening and Tonight:

    Under clear skies, frost will re-form in eastern Wales during the evening. Patchy rain will move into northern and western parts overnight, falling as sleet or snow over northern hills. However, much of the southeast will stay dry until morning. Minimum Temperature -1 °C.


    Rain in the south will ease later, but it will stay drizzly in the west. Sunny spells in the east will fade as cloud builds later in the day. Maximum Temperature 8 °C.

    Outlook for Friday to Sunday:

    Friday will be breezy but milder, with patchy rain and hill-fog. Saturday's strong winds, rain and then wintry showers will be followed by a colder, brighter Sunday with wintry showers.

    UK forecast for the next 5 days

    Sleet, hill snow and ice for the north and east.

    This Evening and Tonight:

    Central and eastern areas will be frosty with a few mist patches. A band of patchy rain, sleet and hill snow will move southwards from Scotland to central England and Wales. Patchy ice may form where wet surfaces freeze.


    After patchy rain and sleet clear from the south, eastern parts will have another bright cold day. It will become cloudier in the west with some rain here later.

    Outlook for Friday to Sunday:

    Friday: breezy, often cloudy but milder, with patchy rain and hill fog. Saturday: strong winds and heavy rain followed by showers. Sunday: colder, brighter and windy with wintry showers.

    Outlook for the UK over the next 6-30 days

    UK Outlook for Monday 28 Jan 2019 to Wednesday 6 Feb 2019:

    Cold and showery conditions are likely at first on Monday, ahead of thicker cloud and rain, perhaps preceded by snow, which is expected to move eastwards later in the day. Cold and showery weather will probably make a return on Tuesday. Beyond there, the broad signal is for the unsettled period of the weather to continue, with further bands of rain and hill snow moving east or southeast across the UK, interspersed with brighter showery interludes. Snow remains a risk, mostly in the north, but perhaps further south too, and frosts could be quite widespread. There is still a chance that even colder conditions may develop later in the period with winds swinging round to the east or northeast, bringing an increased possibility of snow.

    UK Outlook for Thursday 7 Feb 2019 to Thursday 21 Feb 2019:

    This period will most likely start changeable and cold, with spells of rain and hill snow, occasional stronger winds, and brighter showery interludes. As we head further through February there is an increased chance of seeing very cold conditions developing with a greater probability of northeasterly or easterly winds. This will bring an increased risk of widespread, perhaps severe frosts as well as snow, especially in eastern areas. In this scenario the driest conditions will be across the west and northwest, whilst the south could see wetter and occasionally milder spells, bringing the risk of some significant snow, but only if very cold air becomes established across much of the UK.
