Dreaming of a white Christmas?
Whether or not flakes of snow actually fall on Dec. 25, a Christmas is considered to be white when there is at least an inch of snow on the ground, according to the National Weather Service.
Historically, the probability of seeing a white Christmas in the Chicago area is fairly slim.
The National Oceanic and Atmospheric Administration created an interactive map outlining past weather patterns collected between 1991 and 2020 to predict the historical probability of there being at least an inch of snow on the ground Dec. 25.
According to the map, the historical probability of a white Christmas stands at 35% in Chicago. In northern areas, the probability increases. It's 43% in Oak Brook, and 53% in Streamwood.
This year, Chicago saw it's first measurable snow on Nov. 15, three days before the city typically sees its average first snow of the season.
On the radar for weather in the coming days, NBC 5 Storm Team says the area will likely see scattered flurries take shape, but snow accumulation is not expected.
