Hail and Wind Event - March 23, 2013
|
|
On the morning of Saturday, March 23, an upper trough began digging into the center of the country. That evening, within the resultant southwesterly flow aloft that was streaming through the southeastern United States, a surface low began to develop near New Orleans. Because of the lack of any real upper level feature to drag it or the warm front northward, the surface low never really amounted to much. North of the warm front, which was draped across the Gulf Coast, elevated storms began to develop. Steep mid-level lapse rates (evident in the 12z/March 23 BMX and 00z/March 24 JAN upper air soundings below), along with sufficient hail growth zone CAPE values of 1000-1500 J/kg and 0-3km Storm Relative Helicity values of 400-600 m^2/s^2, these elevated storm became well-organized. Starting in south-central Mississippi and moving into central Alabama, one of these storms traversed Sumter, Hale, Perry, Bibb, Chilton, Coosa and Tallapoosa Counties, dropped hail stones of 1 to 1.75 inches in diameter and created damaging wind gusts. Below are the environmental conditions and local storm reports from that evening.
