Up here we have seen the low temps last couple of weeks but have had very little snow this winter. Fields are bare, maybe 3-4" snow in all this winter and much of that melted in warmer weather in January.
Interesting that in this cold-dry snap here, temps north of Hudson's Bay have been often above 0C in places, right up to Alert. Cooled down to -20s last few days up there though.
I don't bother cleaning the snow off the prime focus dishes until it builds up a few inches. Think I cleaned them off once this winter just because I was checking them anyway. It's a good idea to clean them if the snow is wet and the forecast is for cold weather; that way it won't freeze into solid ice.. difficult to keep up though if it keeps snowing.
The snow mostly slides off the offset dishes. Definitely an advantage to that dish configuration.
