Some areas only received a dusting, but white-out conditions and hazardous roads were reported in other places, including the Indiana Tollway in LaPorte County, where a plow needed to be towed off the side of the road.
The conditions tricky for driving, but it's still a welcome Christmas sight for Michigan City resident Teare Russel.
"For two years we haven't had snow so for it to be snowing now, it feels good. It's a blessing," said Russell. ""I think this will bring happiness to a lot of people. We had an off year."
The snow in northwest Indiana is expected to end by mid-morning.
Of course some people may be heading outside for a Christmas Mass, so be sure to give yourself extra time this morning in case the roads are dicey in your area. And definitely bring a jacket with bitter cold temperatures across the Chicago area.
