The Met Office has given a major update to its snow forecast in Wales. Previously, on Saturday, the weather agency's maps showed there would be some in north Wales tonight (Sunday) and on Monday, and then snowfall in different parts of the country on Tuesday with particularly heavy downfalls in the south east.
The latest forecast still shows a little bit of snow up north on Sunday and Monday. Snow is expected to fall in the south west on Tuesday and head across the south, before just falling in small patches in the north by the evening. There is a more snowfall expected across the country throughout Wednesday, while Friday is set to be very wet everywhere.
Whether there's snow or not, temperatures are set to fall in the coming days, from Monday evening temperatures will fall to around 0C or below in most parts of Wales and stay low throughout most of Tuesday and into Wednesday.
We've captured the periods of snowfall according to the maps from today until Friday. The colours shown on the maps correspond to the type of precipitation (rain is blue, snow is white and hail is orange) and the darker the colour the heavier that precipitation is - so white is light snow, and dark grey forecasts heavy snowfall.
