Chicago White Christmas questions
Does snow have to fall on Christmas Day in Chicago?
No. A White Christmas means at least one inch of snow is on the ground on December 25. Snow can fall earlier and still count.
When should I trust the Chicago 2026 estimate most?
The estimate becomes more actionable as December progresses, especially when observed snowpack and the Christmas-week forecast are available.
