ATLANTA — The snow that blanketed parts of the Deep South on Friday delighted schoolchildren with an unexpected holiday but also revived panicky memories for many adults of past storms that trapped commuters on interstates for hours.Businesses closed and commuters left work early as snow mixed with rain fell in downtown Atlanta, causing traffic jams on slushy roads far ahead of the usual rush hour."We're surprised that this little snowfall would cause this much disruption to the entire city," said Lucas Rachow, who stood outside with several colleagues holding suitcases as they waited for a ride to the airport.Rachow was heading home to Switzerland after a business meeting and said he didn't know if his flight had been canceled.The National Weather Service said just 1 to 2 inches (3-5 centimeters) of snow accumulation was expected in Atlanta, with higher amounts possible in the city's northern suburbs. It was enough to remind some residents of the 2014 storm that brought the city to a standstill and stranded motorists on roads overnight with just 2 inches of precipitation.At a Jersey Mike's sandwich shop in downtown Atlanta, manager Mike Thomas said the snow had driven away his clientele. He was calling his boss to see if they should close up early, just as the barbecue restaurant next door had done."I'm terribly slow," Thomas said, just after what should have been the lunch rush.Accumulations of 6 inches (15 centimeters) were reported in Mississippi and northern Georgia, while at least 5 inches (13 centimeters) fell in Alabama.
