Clear and cold overnight.
This Evening and Tonight:
It will be dry through the evening and overnight. Clearing skies and easing winds mean that temperatures will fall sharply, with a hard frost likely and some fog patches possible by the morning. Minimum Temperature -3C.
A bright, frosty morning. Dry with sunny spells for the rest of the day, although cloudier in the west with rain possible by evening. Maximum Temperature 5C.
Outlook for Saturday to Monday:
Winds strengthen on Saturday as rain spreads east. Milder Sunday with sunny spells and blustery showers later. Starting dry Monday, but turning windy with some rain later.
Day 6 to 15
Tuesday will see some unsettled and windy weather with coastal gales, cloud, and outbreaks of rain and drizzle moving eastwards across the UK. The rain and drizzle will be followed by sunny spells and scattered, blustery showers. Showers will fall as snow over northern higher ground. As we head through the remainder of the week and into the Christmas week it will probably stay unsettled, with further spells of wind and rain, these interspersed by some brighter and showery weather. Temperatures on the whole look likely to be a little milder than average. However, in the period after Christmas Day there is an increased likelihood that milder spells will become short-lived and a colder and more showery northerly or northwesterly regime could become established across the UK.
Day 16 to 30
The most likely scenario for the end of December is for periodically unsettled Atlantic weather to move across the UK from the west. However, there is an increased likelihood that the milder, Atlantic weather will become short-lived and a colder and more showery northerly or northwesterly regime will become established across the UK. Through the first half of January, there is an increasing likelihood of a return to colder than average conditions with an increase in the likelihood of overnight frost and fog, as well as some snow.
