About half an inch of snow and 28 below at 8am on Keystone Ridge. Here's how it snows at these cold temperatures. The morning sounding shows the deep cold air (-30C and colder) is about 400 meters thick. The snow producing clouds have a temperature around -20C to -23C. This is reflected in the sand-like consistency of the snow this morning.
