The National Weather Service says Indianapolis and Omaha, Neb., could get at least a foot of snow. Snow is expected to start in those cities late Saturday afternoon and continue through midday Sunday. Decatur, Ind., could see 9 inches, while northeast Indiana and Northwest Ohio could get 6 inches or more as snow increases on Sunday into the evening, according to the weather service. The snow will be wet and heavy, which could pose a health hazard during shoveling, the weather service warned.
The system is expected to carry snow into the Northeast early next week.
In the South, forecasters say the system could spark tornadoes in Louisiana and Mississippi on Saturday.
