Wow that was amazing, looked very dark toward my NE, then from bright winter sunshine to blizzard mayhem in 5 minutes. Visibility was down to less than 50m's at times, particularly when the wind blew and flakes turned haily. IM absolutely astounded, only wish my camera was working as that was something i haven't witnessed for a while. True intense, powdery massive flakes, wind, drifting and then a hail shower. My back garden has around a CM.
