The forecast patterns shown by the various meteorological models are still at odds with one another, and the next week or so will be crucial in deciding the weather for December. Generally there will be some changeable and unsettled weather over most parts of the country to start with, but a colder brighter spell is likely by mid December.
Saturday 22 November to Friday 28 November
During this week an area of low pressure is likely to form to the west of the country allowing weather fronts to move eastwards, so over the weekend there will be quite a change in the weather.
To start with it will be cold with northwesterly winds bringing sunshine and showers. Most of the showers will be over Scotland, Northern Ireland and northwest England, but some will penetrate well inland over England and Wales as well. These will die out overnight to give some frost patches, but showers will continue over north and northwest facing coasts and hills.
During Sunday a weather front will push in from the west bringing cloud and a band of rain, but it is likely to be late in the day before the rain reaches eastern parts of England. The exact track of the low pressure after that is in some doubt, but it will almost certainly move across the country giving a period of rain for most places, but this will turn to sunny spells and showers as the low moves away to the east. With the winds again turning into northwest, and pressure building to the west of the country, the showers will die out to give colder and much sunnier weather, but with frost at night.
In the latter part of the week, more unsettled weather is likely over parts of England and Wales, especially in the south, but it will stay largely dry and clear over Scotland and Northern Ireland.
Saturday 29 November to Friday 5 December
This is a critical week as far as the forecast weather pattern is concerned. At the moment I think that the low pressure is probably going to be to the west of Ireland giving mainly southerly winds across much of the country. However, the low may eventually drift in from the west, and become centred over Ireland or northern England. So, with the uncertainties in the weather pattern being taken into account, it does seem likely that low pressure will be the dominant feature this week.
Scotland and Northern Ireland will have some rain, followed by sunny spells and showers, and it will become quite windy at times. A cold east to southeasterly wind is expected to develop across these northern areas of the United Kingdom.
England and Wales will also be pretty cloudy with periods of rain, interspersed with sunny spells and showers, but with predominately west or southwesterly winds, it will feel much milder than over Scotland or Northern Ireland.
Saturday 6 December to Friday 13 December
With low pressure centred to the west of the country, the week will start unsettled with south or southeasterly winds, but by the middle of the week, high pressure will start to build.
Over Northern Ireland, western Scotland and the western parts of both England and Wales it will be quite unsettled with periods of rain followed by sunny spells and showers, and the rain could well be quite heavy at times. By the end of the week much of the rain will have died out to give increasing amounts of sunshine, but some fog and frost at night as well.
Eastern Scotland, northeast England, east Wales, the Midlands, east Anglia, central southern and southeast England will also have a rather unsettled weekend with further outbreaks of showery rain. But this will start to die out during the early part of the working week, and as it becomes drier, so it will become much sunnier too, but this will lead to widespread frost and fog problems at night, lasting well into the morning.
Saturday 13 December to Wednesday 17 December
High pressure will become firmly established and start to dominate the weather across most parts of the country.
So for all of us this will be the start of a cold period of weather with widespread frosts and dense patches of freezing fog. In some parts of the country, such as the vale of York, eastern Wales and the Thames Valley, the fog could well linger all day making these places very cold with the daytime temperature barely reaching freezing. For most parts, though, the fog will slowly lift and thin to give some hazy sunshine, especially in the afternoon.
