UK forecast for the next 5 days

Turning much colder through Wednesday with snow in the north.

Today:

Cloudy, mild start in the south with some rain, locally heavy and squally, before clearing by lunchtime. Much colder, brighter conditions follow with frequent sleet and snow showers in the north/northwest with some accumulations likely. Windy, gales in the north.

Tonight:

Windy night with frequent snow showers, locally thundery, across northern and northwestern parts. Scattered wintry showers elsewhere, these mainly in west. Clear spells allowing a frost away from western coasts.

Thursday:

Another cold day with sunny spells and sleet and snow showers. Across southern parts, however, snow primarily falling over hills. Strong winds, especially in the west, will accentuate the cold.

Outlook for Friday to Sunday:

Sunshine and wintry showers Friday, mainly rain to low levels. Thereafter, colder northerly winds will bring snow showers to northern parts and windward coasts, but some may push well inland.

Updated at: 0300 on Wed 28 Jan 2015

Outlook for the UK over the next 6-30 days

UK Outlook for Monday 2 Feb 2015 to Wednesday 11 Feb 2015:

The general cold feel to the weather will continue during the first week of February, as the northerly winds bring hail, sleet and snow showers to the country. Showers will be frequent across northern parts and may affect other coastal areas at times, with widespread overnight frost and ice too. There is a low probability of more widespread rain and snow over southwestern areas, early in the week. Strong northerly winds at first, with gales in places, will lead to a significant wind chill, this gradually easing. The driest and brightest weather will be across sheltered southern parts. There are signals for a change to less cold temperatures and spells of rain by next weekend, though there is still a risk of snow, frost and ice at times.

UK Outlook for Thursday 12 Feb 2015 to Thursday 26 Feb 2015:

It looks most likely that unsettled conditions will continue across much of the UK with temperatures closer to normal when compared to the start of February. This may be more obvious across parts of southern and western Britain where it might be a little wetter than average as spells of wind and rain make their way in from the Atlantic. However, there is the possibility of pressure building around the middle of the month bringing more settled conditions, particularly in the south.
