The big chill has finally arrived.
It's feeling colder today with snow in parts of the north and west of Wales with 5cm of snow reported near Dolgellau this morning.
The snow is coming from clumps of showers moving in from the Irish Sea and although the sea is still relatively warm - the cold air over the warmer sea makes the atmosphere very unstable, forming large shower clouds.

Who actually gets the showers is very dependent on the wind direction and currently the surface wind is from the north or north-north east so the north and west of Wales is most prone to catch the showers. The wind is stronger today so the showers are being blown well inland from the sea.
Tomorrow is trickier with a disturbance over Ireland moving in to Wales. This will bring a spell of rain, sleet and snow. Most of the snow should be in the north and west but I wouldn't rule out some snow in Powys and the south, tomorrow afternoon.
Two to five cm of snow is possible in places, 1 to 2 inches, especially on higher ground. See the Met Office warnings for more details.

Over the weekend it will be very cold with a significant wind-chill. There will be the odd snow shower in places but it will otherwise remain dry.
The best of the sunshine will be in the west and north west with top temperatures of around 1 to 3 degrees Celsius.
Next week will remain very cold and there is a 30 to 40% risk of a blizzard on Tuesday and Wednesday.This is not definite at the moment - just a possibility but if it did happen it could cause major disruption, so keep a close eye on the forecast.
