The February 2015 Southeastern United States winter storm was a rare winter storm that dumped up to a foot of snow in the Southeast, an area that rarely receives such heavy snowfall.[1][2] Forming out of a shortwave trough that developed over Texas near the Gulf of Mexico on February 24, the storm quickly made its way over the southern United States, coalescing into a surface low-pressure area as it did so. With arctic air unusually far south, this helped spawn heavy, wet snowfall across the northern portions of several southern states, including the suburbs of Atlanta, Georgia. States such as Alabama and Georgia declared a state of emergency in the northern portions of the state due to the possibility of up to 6 inches (15 cm) of snow, which was normally never seen.
School closures were reported across a wide swath of the south due to treacherous conditions, and four people were confirmed to have died as a result of the winter storm. A very uncommon occurrence, the snow in the southern reaches of the United States was considered extremely rare, mainly due in part of how heavy the total accumulations were; in some areas it was their heaviest snowstorm on record. The storm was the third of five winter storms that made their way across the United States in a period lasting from late February into early March.
