On higher ground they said, but on the Met Office site they'd lumped almost the whole of Scotland under that forecast.
And 15cm is nowhere near the amount that actually fell on lower ground, 15 inches was closer to the mark (two and a half times more, and God knows how much on higher ground).
Even at the lower end of the scale, the councils should have had the gritters out, but as usual waited until it was too late.
Ten years ago you'd see gritters on the roads regularly during the winter and on the M8 they'd be out all night (I had to follow them often enough when I was coming home from Glasgow after nightshift), but these days you rarely see the things.
I take it they don't want to/can't pay the nightshift rates these days.

On the one hand they say 'severe' but then say it's going to be 2 - 5cm except on the high ground.
Personally I took that to mean that there might be problems with visibility at times, but the roads would stay relatively clear (2-5cm of snow isn't a great deal to cope with on Scottish roads in winter).
I suppose most people who saw that probably thought the same way.
