The first flakes began to fall on Sunday night. Blown in on a strong north wind, they moved horizontally, seeming to fly past without making contact with the land at all. But by the next morning, hills were dusted white and schools closed.
Forecasts warned of a polar low to the north of Shetland. Such areas of low pressure can bring sudden severe gales and heavy snow. I watched clouds build on the horizon, the sky darkening with their approach.
