Ah yes. I remember that event very well. It was a Good Friday in about 1975.. I think it was a polar low. It produced a good 3” of snow in south herts where we then lived. The next day was a glorious cold sunny day and ordinarily I would have been sledging in the local hill after breakfast.

But instead I had to travel with my school to sing St Matthews Passion in the Festival hall. When we finally got back home in the evening the snow was all gone. I was bitterly resentful and have not listened to the Passion since.

Not of course March but a fortiori :-)
