Well actually, it isn't because we had loads in January. This post is a day late - the snow arrived overnight Thursday/Friday am.
I was somewhat amazed because on closer inspection, I found that the net I had over my onions and lettuce (primarily to keep critters off the bed) was keeping most of the snow off the plants beneath it.
Surprising because the holes in the net are quite wide - about 2.5cm/1" so I assumed the snow would have passed through them. Wonders will never cease.
