A low pressure system developed over the Gulf of Mexico over the weekend of March 23-24, 2013. The low became enhanced by a strong upper level jet as it tracked across the southern U.S. A prefrontal squall line developed ahead of the trailing cold front and pushed across East Central Florida during Sunday afternoon. The squall line produced a large swath of wind damage as it passed, with numerous reports of damaging thunderstorm wind gusts, along with a few reports of large hail.
