Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 24 Feb 2018 to Monday 5 Mar 2018:

The weekend will be mostly dry, with frost and freezing fog patches clearing to give cold days with sunny spells. Snow flurries may develop across eastern and southern areas where a brisk easterly wind will make it feel bitterly cold. It may be less cold in the far northwest with some rain possible. Into next week it is likely to turn colder with brisk easterly winds, giving a significant wind chill, especially in the south and east. This will give the risk of further snow flurries, which may become heavier and more widespread. There is also the risk of more significant snow pushing northeastwards across southern and some central areas. The north and west will be brighter, and it may be less cold across the far northwest at times.

UK Outlook for Tuesday 6 Mar 2018 to Tuesday 20 Mar 2018:

At the start of this period it is likely to remain cold or very cold for many with widespread frost and brisk easterly winds from Continental Europe, making it feel raw. This will continue to bring the risk of significant snow across some southern, eastern and central parts of the country, whereas towards the north and west it will start drier. As we head through the middle of March, there is a lot of uncertainty in the forecast, but it may start to turn more unsettled and less cold with the wettest and mildest weather spreading in from the southwest. In contrast, northern and eastern areas could remain colder well into March.
