Unseasonably mild air has managed to melt a lot of the recent snowfall - so much so that only trace amounts to none were left across much of the region. As a result, it looks like a "brown" Christmas for many.
A "white" Christmas is considered to be an inch of snow on the ground that morning (or falling that day).
