Mid-February 2014 North American winter storm of further-north Georgia received unusually heavy snows. Precipitation started as light rain late on the 10th, with significant snow by the following morning while still above freezing, turning back to light rain before ending by mid-day. More light rain began after midnight, changing to snow as temperatures fell, then to sleet, freezing rain, back to sleet again before another significant snow by the morning of the 13th. Areas north of the city generally got mostly snow and sleet, while a large swath from the south metro area eastward got the heaviest ice accumulations, though a dry slot at mid-day proved
Hail the hail to the radar, and the echo is further away from the radar than the actual location of the hail on the same radial path, forming a cone of weaker reflectivities. More recently, the polarization properties of weather radar returns have been analyzed to differentiate between hail and heavy rain. The use of differential reflectivity (formula_1), in combination with horizontal reflectivity (formula_2) has led to a variety of hail classification algorithms. Visible satellite imagery is beginning to be used to detect hail, but false alarm rates remain high using this method. The size of hailstones is best determined by
