A bright start on Monday, but clouding over.
This Evening and Tonight:
A few showers are likely this evening, but these will ease to leave a largely dry night with clear spells. The winds will ease too and it will turn chilly, particularly in rural spots. Minimum Temperature 1C.
After a bright start, cloud will arrive from the west through the day. Some patchy rain is possible, particularly in the west, but for many it will remain dry. Maximum Temperature 11C.
Outlook for Tuesday to Thursday:
Tuesday largely cloudy but mainly dry. Rain will spread eastwards overnight and through Wednesday, turning lighter and patchier. Stronger winds by Thursday, and possibly some heavy rain.
Day 6 to 15
Friday looks likely to be wet and possibly very windy in the northwest, and colder and drier in the far east. There could be some snow where the colder air meets the wet weather, most likely over the hills in the north, but it may fall to lower levels in places too. Over next weekend, the weather is likely to be changeable and often windy and cloudy, with showers or longer spells of rain at times. Any snow is most likely on high ground in the north. During the following week, eastern and southern areas may become drier for a time with more sunshine but clearer colder nights would lead to some night frost. Overall, temperatures are likely to be around normal for the time of year.
Day 16 to 30
The early part of this period, including Christmas, is looking 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. However, later in the month and into the New Year, there is the chance of high pressure becoming established close to the UK. This would bring drier and colder weather, and a greater chance of night frosts. There remains some uncertainty about this; if the high pressure is offset to the west or east of the UK, wet and windy weather would dominate.
