The temperature is slightly above freezing out there. A lot of wet snow has fallen in recent weeks.
And the wet snow just won't stop coming. That supermarket parking area is turning into a lake. A neighbor told me her car got stuck at a parking area in town this morning. It took several people to push it to get it moving.
Left there by a snow plow. That stuff is really wet. I'm guessing it may be over half as dense as water. Fresh powdery snow is very much lighter.
