Snow showers Saturday dropped 2 to 4 inches of powder and caused slippery conditions on region roads.
Indiana State Police said they were busy responding to various crashes, slide-offs and disabled motorists. Some minor injuries were reported.
The Indiana Department of Transportation encouraged motorists to be aware of the forecast and plan travel accordingly. In addition to the rate of snowfall, cold temperatures and blowing winds also decreased visibility in some areas, and made driving conditions difficult.
On Sunday, forecasters say it will be mostly cloudy and windy, with a high of 33 degrees. Winds are expected to be southwest at 20 to 30 mph. Another deep freeze is predicted for Monday and early this week.
Ben Matlock, manager at Gus Bock Ace Hardware in Lansing, didn't mind the snow and ice Saturday.
"Besides the salt and shovels, we can always gauge the kind of winter we're having based on how many snow blowers we sell," said Matlock, who has worked at the store on Ridge Road for seven years.
"Last Saturday, we sold 12 snow blowers in about five hours. Winter weather makes for a busy Saturday."
A fiery crash involving a semitruck and other vehicles on northbound Interstate 65 near Lafayette about 3 p.m. closed both directions of highway, hampering weekend travelers. The interstate opened late Saturday but traffic in the area remained slow.
