Despite the temp, it must be wetbulbing nicely aloft. The snow is blowing around with the wind. Not the messy slush parachutes you'd expect. Steady light snow.
The height of it where you are could be close to 10:1 if we can get that filthy lift in the DGZ. The higher elevations may be even better if they can get to like 31.5F or something. Otherwise yeah that sounds about right.
