Well, you can never say never in Chicago, but generally the beginning of November does not bring significant snow. You may see some flurries - you also may get some beautiful relatively warm days. Overall, November tends to be a gray month. Bring an umbrella, bring some layers to wear and have a good time no matter what the weather!

Here is a link to a site (kind of crude) that you can scroll through day by day to see the average highs/lows by day.
