Lambing snows and April showers

Every crofter in the Highlands of Scotland will tell you about the lambing snows.
Last year  at this time we drove south to Inverness to have our winter tyres replaced with summer ones. The weather was beautiful.
But - It started snowing just after we left the garage and  by the time we reached Sutherland there was deep snow. Our croft house is up a hill. We made it but it was touch and go

April Showers -
That weird situation when there is lovely bright sun and it feels like spring and then
from nowhere
it rains
briefly
and then there is bright sun again.
I reckon this is just the same as the lambing snows - just a warmer version!
