Colder in the west tonight, with frost possible.
This Evening and Tonight:
Generally dry with clear spells across many parts overnight. Breezy along coastal areas but some lighter winds further inland, leading to colder temperatures and a risk of frost. Minimum Temperature 0C.
Remaining dry and largely sunny or bright, though feeling cold in the easterly breeze. Temperatures falling rapidly after dusk, with frost developing overnight. Maximum Temperature 6C.
Outlook for Friday to Sunday:
Frosty early Friday, then sunny intervals and mostly dry. Saturday starting dry and bright after widespread frost, then windy with heavy rain spreading east. Milder Sunday, with sunshine and showers.
Day 6 to 15
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.
Day 16 to 30
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.
