The snow forecast for Christmas 2017 is still uncertain. But here's a look at what the weather was like during the past 10 Christmas Days in New Jersey.
Over the past week, weather fanatics across New Jersey have had high hopes that they will wake up Christmas morning to a light blanket of snow on the ground.
With weather guidance models flip-flopping each day, it's still uncertain whether snow will fall on the Garden State on Christmas Day. Some models are projecting light snow in the early-morning hours on Dec. 25, and others are projecting rain.
If the rainy forecast holds up, this will be the eighth straight year that most of New Jersey has not had a white Christmas.
UPDATE (10 a.m. Friday): Computer guidance models are starting to be more consistent, so the odds of getting a white Christmas this year have gotten better -- at least for the northern half of New Jersey. The National Weather Service is now predicting 2 to 3 inches of snow could fall in northwestern sections of New Jersey from late Christmas Eve through early Christmas morning, and 1 to 2 inches of snow could fall in north-central counties like Morris, Somerset, Hunterdon, Middlesex and western Monmouth. Even New York City could get 1 inch of snow on Christmas morning, although rain could mix with the snow.
So, when was the last white Christmas, you ask?
The last Christmas with 1 inch or more of snow on the ground across most of the state -- either freshly fallen snow or lingering snow from an earlier storm -- was back in 2009, according to climate records from the National Weather Service and New Jersey State Climatologist David Robinson, whose office is based at Rutgers University.
The driving force in 2009 was a big storm that dumped nearly 2 feet of snow in southern New Jersey and 10 inches or more in central and northern New Jersey five days before Christmas. When Dec. 25 arrived that year, the ground was still covered with anywhere from 3 inches to 14 inches of snow.
Worth noting
Since New Jersey is packed with 565 towns and has different climate conditions in each region because of the varying terrain, ocean influences and atmospheric flow patterns, people in a few locations experienced a white Christmas more recently than 2009.
On Christmas Day in 2012, a handful of towns in northern and western New Jersey had 1 to 2 inches of snow on the ground, and on Christmas Day in 2013 two climate stations in northwestern New Jersey reported 1 inch of snow, but there was no widespread snow across the state.
Whether those two years can be classified as "white Christmases" for New Jersey is up for debate, but residents in some towns did have conditions that met the National Weather Service's definition of a white Christmas. (One inch or more of snow on the ground on Dec. 25.)

Close calls
During the past 10 years, the Garden State has had several close calls with storms that almost arrived in time for Christmas Day but ended up hitting too early, too late, or when temperatures were too warm to produce snow.
Here's a look at the weather conditions that were reported on each Dec. 25 from 2016 back to 2007 at New Jersey's two major climate sites monitored by the National Weather Service: Newark Liberty International Airport and Atlantic City International Airport.
What you will find is something that's not a surprise to climatologists: A white Christmas is a rare event in New Jersey.
NEWARK CHRISTMAS STATS
Dec. 25, 2016: No snow
Note: 3.0 inches of snow fell on Dec. 17, but temperatures were in the 40s, 50s and low 60s heading up to Christmas Day. So there was no snow on the ground on Dec. 25.

Note: Records show Newark had 2 inches of snow on the ground on Christmas Eve, from three small snowfalls earlier in the month - Dec. 19, Dec. 20 and Dec. 21 - but no snow on the ground on Christmas Day in 2008.

ATLANTIC CITY CHRISTMAS STATS

The city had a bit of rain on Dec. 23 and again on Dec. 24, so the moisture was in place but temperatures were too warm to support snow.
Dec. 25, 2012: No snow, but a close call!
Note: Atlantic City had only a trace of snow the entire month - on Dec. 22 and almost a quarter-inch of rain on Dec. 24 and 2.6 inches of rain on Dec. 26. If the temperatures had been colder, the city could have had a white Christmas.

Dec. 25, 2010: 0.1 inches of snow - very close call!!
Note: Some people would consider 0.1 inches of snow a white Christmas, but it falls short of the weather service's standard of 1.0 inches or more. Also worth noting: Atlantic City had a big snowstorm on Dec. 26 into Dec. 27, with 18.4 inches of snow on Dec. 26 and 1.6 inches of snow and freezing rain as the storm winded down on Dec. 27.
Dec. 25, 2009: No fresh snow fell that day, but there were 5 inches of snow on the ground. So technically, it was a white Christmas in A.C.!
Note: Records show the snow that was on the ground on Christmas came from a massive snowstorm that hit the region on Dec. 19 into Dec. 20. The city got 11.4 inches on the 19th and 0.7 inches on the 20th. Bad news for snow lovers: Heavy rain and mist washed all the remaining snow away the day after Christmas.
Dec. 25, 2008: No snow
Note: Records show Christmas Day was warm that year, with a high of 63 degrees and light rain. Atlantic City had only 0.3 inches of snow the entire month of December, and that was on Dec. 6. A trace of snow fell on Dec. 31.
Dec. 25, 2007: No snow, but a close call!
Note: Atlantic City had almost a third of an inch of rain on Dec. 26, so it was a close call in terms of moisture and timing.
