Chicago is experiencing windy conditions with a chance of snow flurries, as reported by CBS News Chicago. The city is also preparing for a rare winter tornado outbreak that has already affected Southern Illinois and Indiana. The current weather pattern is influenced by lake-effect conditions, which are typical for this time of year, causing localized snow showers and flurries due to cold air passing over the warmer waters of Lake Michigan. These conditions can vary significantly across different areas, with some experiencing heavier snowfall and others only light flurries.
