Most of us would love to go through a Winter season without snow, but even those who hate snow the most probably wouldn’t mind a little snow on Christmas Day.
In order for a Christmas to be considered a “White Christmas”, there must be at least 1.0″ of snow on the ground regardless of whether or not snow is actually falling.
Historically, the odds of having a white Christmas in Central Illinois is not that great. The historical probability of a white Christmas in Central Illinois is between 25% and 40%. In other words, on average Central Illinois sees a white Christmas only 2-4 times in a 10 year period. For Peoria and Bloomington, the historical probability of having at least 1 inch of snow on the ground is 35% while Lincoln’s historical probability is at 29%. It’s no surprise that the Chicago area fairs better. At Chicago Midway, the historical probability of having 1 inch of snow on the ground is 41%.
Since 2007, the Peoria area has seen four white Christmas’…
2017 – 3.0″
2012 – 1.0″
2010 – 8.0″
2009 – 1.5″
This year, it appears our chances of seeing a white Christmas are slim. While the weather pattern is looking a little more active the week of Christmas, the chance of a storm producing are low. One storm may bring few non-accumulating snow showers to Central Illinois on Sunday, December 23rd.
Perhaps our best chances of seeing a white Christmas this year will come on Christmas Day. A stronger storm may move in on Christmas Day, but even that storm appears to be more rain than snow. If the storm can bring in a little more cold air, then our chances of a white Christmas in 2018 could increase.
