Met office update
UK Outlook for Monday 4 Dec 2017 to Wednesday 13 Dec 2017:
Next week starts rather cloudy, but dry with some rain or drizzle in the north and west. Meanwhile, the best of any brightness at first is likely in the southeast. The rain will slowly move southwards with colder, brighter and showery conditions returning across all areas. The colder and brighter conditions are likely to remain through the rest of next week with the chance of some heavy showers, some of which will fall as snow. For the remainder of this period a blocked pattern is likely to persist meaning it will probably stay mainly dry and cold with widespread overnight frosts and a mixture of sunshine and showers. These falling as sleet or snow, chiefly over the hills but also to lower levels.
UK Outlook for Thursday 14 Dec 2017 to Thursday 28 Dec 2017:
At the start of this period confidence is low, but high pressure is more likely to dominate to the north and west of the UK, which will give us mainly dry and cold conditions, with a mix of sunshine and showers. The showers are likely to fall as sleet or snow, chiefly over the hills but also to lower levels at times. Temperatures are set to be cold, with widespread frosts overnight. However, through this period, there is an increasing chance of seeing Atlantic weather systems cross the UK, with an associated increase in rainfall, especially across western areas. This would also bring about generally milder conditions.
