All you might say is that it went from sunny and clear to "OMG I can't see in this blizzard" in about 10 minutes.

I really think that what screwed everyone was that the roads weren't gritted properly. That nearly caught me out on a short steep hill that had no grit or salt whatsoever. It wouldn't have hurt to have sent the gritters out in the early afternoon.
