Northwest Indiana could have a white Christmas after all.
A winter storm warning will be in effect from 6 a.m. to 6 p.m. Sunday, according to the National Weather Service.
Accumulating snow will spread across the area Sunday morning through the afternoon, with snowfall amounts ranging from 3 to 6 inches along and south of Interstate 80.
Lake effect snow is expected across the Region, with 4 to 8 inches possible near Lake Michigan, the weather service said.
Periods of moderate to heavy snow are possible, with snowfall rates between one half and one inch per hour during the late morning and early afternoon.
For much of northern Illinois, the the snowfall will cease by sunset late Sunday afternoon, but lake effect snow will linger into Sunday night for far Northwest Indiana.
Much colder air will spread across the Region early next week, with overnight lows frequently in the single digits, according to NWS.
Christmas Day will be mostly sunny with a high near 25 degrees. Temperatures on Tuesday and Wednesday will reach the mid teens. A chance of snow returns Thursday through Saturday.
