UK Outlook for Monday 17 Dec 2018 to Wednesday 26 Dec 2018:
Through the middle of the month, a mix of blustery showers and longer spells of rain looks likely, with a risk of severe gales. Temperatures will be around normal for the time of year, although the south and west could become rather mild at times. However, a chance of some colder air in the north could give the risk of some hill snow. Heading into the Christmas week, it will probably stay unsettled, with further spells of wind and rain, but interspersed by some brighter and showery weather. Temperatures on the whole look likely to be a little milder than average. However, there is a small chance of colder temperatures, which could bring snow to hilltops in the north, and perhaps to low levels for a time in the northeast.
UK Outlook for Thursday 27 Dec 2018 to Thursday 10 Jan 2019:
The end of 2018 is likely to remain fairly changeable with showers or longer spells of rain, possibly wintry over higher ground. Temperatures look likely to be around normal for the time of year, although there is a small chance things could turn colder in late December. However, as we head into the New Year, there is an increased chance of high pressure becoming established close to the UK. This would bring drier and colder weather, but also an increasing chance of some snow showers and nighttime frosts.
