A wide-ranging storm is burying thoughts of springtime weather across a number of Midwestern states under a blanket of snow and slush.
Dozens of cancelled flights and treacherous roadways have been reported as the storm continues to churn eastward.
The National Weather Service issued storm warnings and advisories for Sunday and Monday for as far east as Pennsylvania, and officials were blaming two deaths in separate crashes in Kansas and Missouri on snow-slicked roads.
The system was expected to move into Ohio, bringing between 15-25 cm of snow.
Slick roads were also being blamed for a series of crashes on Interstate 60 north of Indianapolis that sent two people to area hospitals with life-threatening injuries.
The Indiana State Police reported late Sunday that two people in a 2012 Subaru were hurt when the driver lost control while coming upon the scene of a previous crash involving a semitrailer.
Earlier Sunday night, a jack-knifed semi and subsequent fuel leak required a hazardous materials response outside Indianapolis, officials said.
The Fishers Department of Fire and Emergency Services said a tractor-trailer was southbound on Interstate 69 when its driver lost control. No one was injured.
The storm was expected to weaken as it moved into Pennsylvania late Sunday and into Monday, with totals ranging from 10-20 cm.
Before it exits off the coast of New Jersey on Monday night, the storm could leave 5-10 cm in that state as well as Delaware, northern Maryland and southern New York.
To the west, parts of Colorado and northwest Kansas spent Sunday digging out from 25-40 cm of snow that were dumped there Saturday.
Winds gusting at speeds of up to 70 km/h created snow drifts of 2 to 3 feet in the three states.
Transportation officials reopened several closed highways, including a stretch of Interstate 70 spanning from Denver to Colby, Kan.
The storm dumped 15-20 cm of snow from eastern Kansas into central Missouri before tapering off Sunday morning.
TV station KOMU was briefly evacuated Sunday morning because of high winds and a heavy buildup of snow on the broadcast tower next to the building.
Missouri Gov. Jay Nixon announced he was cancelling a couple events planned for Monday because of the weather.
