Met office 30 day forecast:
Outlook for the UK over the next 6-30 days
UK Outlook for Tuesday 15 Jan 2019 to Thursday 24 Jan 2019:
Cloudy, breezy and mild on Tuesday with rain becoming more persistent in the northwest, before spreading to all areas overnight. Following this, Wednesday will see a colder day with sunny spells and wintry showers in the north, where winds will be strong and blustery with a risk of gales. Thereafter, it is likely to remain unsettled with further showers or longer spells of rain and a risk of snow over northern hills, but occasionally to lower levels here too. The best of any drier and brighter weather will be across the south and southeast. Temperatures will be close to average at first, but brief milder spells are still possible. Despite this, it is likely to turn colder towards the end of this period with more widespread frost.
UK Outlook for Friday 25 Jan 2019 to Friday 8 Feb 2019:
During the last week of January and into early February, there is an increased likelihood of cold weather becoming established across all of the UK. This would bring an enhanced risk of snow and more widespread frost, particularly across northern parts. However, there is uncertainty over the extent of the cold weather and it is still possible that some milder and wetter interludes will intersperse this generally cold period, especially in the south.
