The question of whether it will snow in Chicago, and the surrounding areas by Christmas is now NOT looking good. It's about one week before Christmas day and it now looks like there will NOT be a good chance that there will be snow in Chicago.
The reason is that several weather forecasting sites predict there is NOT a good chance of snow by Friday, Dec. 24, and Saturday, Dec. 25.
For example, Weather.com now indicates that on Friday, Dec. 24, the temperature will be 52 degrees Fahrenheit (F) and that there is only a 34% chance of snow or rain showers.
However, on Saturday, Dec. 24 Weather.com indicates that the temperature will be 44 degrees F and that there is only a 6% chance of precipitation.
Moreover, Accuweather.com reports that on Friday the 24th it will be mostly cloudy but the temperature will be 54 degrees. On Saturday the 25th it will be 49 degrees with times of sun and clouds. That is not cold enough on either day to cause snow to fall.
In addition, the US Weather Service 7-day forecast for Chicago and the surrounding area is less clear about snow.
It shows that the maximum prediction for precipitation for Dec. 24 is 34% and for Dec. 25 it is only 14%. That means that there is about a 1 in 3 chance of precipitation on Christmas Eve and a 1 in 7 chance on Christmas Day.
Historically There Has Not Been Snow on Christmas
According to the site, howmuchwillitsnow.com, Chicago has NOT had snow for Christmas in the last six years during Christmas week, other than in 2017 and 2018. This chart goes all the way back to 2015.

Do not expect to see snow in Chicago on or before Christmas this year.
