What are the odds of an ORD flight cancellation Wednesday morning?

Hey everyone! I’m taking a flight to Los Angeles from Chicago Wednesday morning. United airlines emailed me mentioning a potential of cancellation or delays due to the weather Chicago is expecting. What is the likely hood my flight gets cancelled due to the snow that is being expected? Have a lot of plans made for the day I arrive in LA so really hoping everything works out and I’m not stuck in Chicago for a long time
