Hello and welcome to this blog covering the upcoming cold snap for the Western Isles and the UK.
This morning the Met Office issued a yellow weather warning for snow for mainland Scotland.
The warning comes into force at 18:00 Sunday and expires at 23:59 Monday evening.
Now the above graphic above has been really badly put together as it misses out a large chunk of the warning area however it covers the Western Isles so it gives us an idea of how much snowfall we could possibly see. Even though we are not in the warning area we could see a couple of CM of snow fall it will be interesting to see if the Met Office update there warning at all.
The full warning and latest updates can be found here https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings#?date=2021-04-04

In the Western Isles we will be seeing sleet and snow showers from mid afternoon on Sunday into Tuesday. A lot of uncertainty as to how much we will see. A couple of CMs cannot be ruled out. A higher amount could fall over parts of Harris. Winds gusting 40 to 50 mph will make it feel bitterly cold in the wind chill. In between some sunny spells. These wintry showers could be squally with hail mixed in.
I am keeping an eye on this and will update you over the course of the weekend with extra updates if required along with my normal forecasts. If any warnings do get issued I will also update this page. Northerly winds can also cause disruption to ferries due to swell and strength of the wind.
Here is another graphic from the BBC this time showing the cold and snow plunge.
