For the record, the first significant snowfall was 1mm on the 18th December. Since then we have had continual and increasing snow cover. This afternoon (4/1/10) I went out with a ruler and measured the depth of snow in our "front field" near the Kinnaird Road. It is fairly open there and not much drifted - the depth in most places was about 7" but in some places it was 9". Under the windbreak there was only about 2-4".
It has only been above freezing a couple of times since then, with +1 degree on 30th December and +0.5 on 29th December.
