First and foremost, snow is very effective at protecting turf from icy winter winds that can dehydrate and windburn turf. Secondly, snow does act just like a blanket by holding in heat from the ground beneath.
  
This isn't to say that snow is all good, because prolonged periods of snow cover will create a favorable environment for snow mold disease. There are two types, gray and pink. These show up in spring as matted-down areas of turf that require a brisk raking with a leaf rake. Usually not much more than that.
  
But let's end on a positive note. One final benefit of snow is its "fertilizer effect." That's right, due to the nitrogen content in snow, it is often referred to as "Poor Man's Manure." That's one of the reasons your lawn comes out of winter all charged up and ready to grow!

Think spring!
