UK forecast for the next 5 days

Feeling cold with further wintry showers.

Wintry showers mainly in the north and west, but settling snow mainly confined to hills. Still feeling cold, especially in the north and west with significant wind chill. Drier further south and east, with sunny spells developing.

Tonight:

Further wintry showers overnight, with snow over hills. Gales in the north and west, but a windy night for all parts.

Saturday:

Turning colder still across Scotland and Northern Ireland, with showers turning to snow again even at low levels. Feeling very cold in the strong winds, gales in exposed western parts.

Remaining very cold. Fine and dry for many with snow showers around coasts exposed to northerly winds. Risk of more widespread rain and snow in the west early next week.

Updated at: 0306 on Fri 30 Jan 2015

Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 3 Feb 2015 to Thursday 12 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 south-western areas, in the first couple of days. 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 Friday 13 Feb 2015 to Friday 27 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 drier conditions but with colder temperatures than average, particularly to the south.
