There will be a dramatic difference in snowfall from the northwest to the southwest. Parts of the northwest suburbs could see 8″ to 12″ while southern suburbs could see less than 2″.

The changeover, how quickly cold air arrives, will determine how much snow locations see.

Temperatures should remain above freezing for most of the storm. While some may melt, snow rates will be high.

Visibility will be vastly reduced during heavy snow, making travel difficult.

Windy conditions may cause power outages as heavy, wet snow gathers on trees. Winds will be strongest (gust to 40+) around midnight.
