Cold, dry and sunny to end the week.
A cold and frosty start, but a fine day in prospect with long spells of sunshine. Cloud will thicken in the west later, where it will begin to turn breezy. Elsewhere, light winds and feeling cold. Maximum Temperature 4C.
Quickly turning cold and frosty through the evening under clear spells. Becoming windier through the night, perhaps with sporadic outbreaks of rain reaching the far west by dawn. Minimum Temperature -2C.
Windy and feeling bitterly cold through Saturday with a mixture of rain, snow and freezing rain. This will lead to blizzard conditions and widespread ice over some higher ground. Maximum Temperature 3C.
Outlook for Sunday to Tuesday:
Drier and less cold on Sunday, perhaps with the odd shower. Mainly dry on Monday, but turning windier later this continuing through Tuesday with outbreaks of heavy rain.
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.
