• For tonight in Chicago, snow expectations can vary widely by neighborhood due to lake-effect bands. The latest reliable forecasts from major stations typically project several inches, with higher totals in areas downwind from Lake Michigan. Travel may become hazardous in heavier bands, especially during overnight and early-morning hours. For a precise figure and timing, check a current forecast from a trusted source such as the National Weather Service Chicago forecast, and local news outlets’ weather alerts.

How to get the most accurate tonight’s snow forecast:

• National Weather Service (NWS) Chicago forecast: Look for Tonight’s weather, any lake-effect snow advisories or warnings, and expected accumulation by hour or by suburb.
• Local media outlets: ABC7 Chicago, Fox 32 Chicago, and CBS Chicago often issue updated alerts, travel impacts, and hour-by-hour snowfall estimates during lake-effect events.
• Weather apps and websites: AccuWeather, Weather.com, and Weather Underground provide hourly snowfall projections and radar so you can track bands as they move in.

What to watch for tonight:

• Timing: Lake-effect bands can shift, causing rapid changes in snowfall intensity and accumulation within a few hours.
• Accumulation variability: Urban core areas might see different totals than suburbs; southern and southeastern suburbs sometimes get higher amounts.
