Atlanta ? Snow, rain and sleet spread across parts of the South on Saturday, dusting lawns and shrubs with flakes and leading airlines to cancel several hundred flights.

Enough snow fell in Montgomery, Ala., for children to make snowballs to toss in front of the state Capitol, although the snow melted on contact with pavement.

Snow also fell as far south as southwestern Mississippi, with totals of as much as 3 inches, although the ground was too warm to allow it to accumulate. It was that area’s first snowfall since 2001, the National Weather Service said.

All five runways at Hartsfield-Jackson Atlanta International Airport were reported open, but an automated Internet report from the Federal Aviation Administration said some flights bound for the airport were delayed by more than four hours.

Delta Air Lines Inc. had about 280 flight cancellations Saturday, spokeswoman Betsy Talton said. AirTran Airways spokesman Tad Hutcheson said 78 flights were canceled by afternoon and more cancellations were expected.
