Just to add to this thread....
We rarely have a white Christmas here, with most of the snow coming between January and March, but we got just over a foot of snow in 12 hours.
Yesterday Megan and I were hanging Christmas lights and the grass was still green.
These pics were taken about 24 hours apart. I'd have taken pics sooner, but I spent much of the day shoveling and cleaning large piles of snow off the cars.
Oh, and there is probably more coming in the next 24 hours or so.
