Cold, but then a White Christmas possible

Bitterly cold arctic air is riding into the area off the snow pack deposited by the weekend storm west and north of Chicago. Wind chill advisories are out in the areas shaded pink on this map.
26 of the past 50 years have produced white Christmases in Chicago–defined as Christmas Days with 1″ of snow or more on the ground! That’s 52% of the Christmases in the past half century–more than the 42% climatological average over the city’s 128 year snow recording dating back to the 1884-84 snow season. We’ve posted the Illinois State Water Survey’s plot of Illinois White Christmas possibilities.
This Christmas is likely to join their ranks. A Clipper-type system is diving southeastward into the Midwest and stands a good chance of bringing us 1-3″ of snow. Snow may fall over roughly a 10 hour period commencing late Tuesday night.
