An upper level low pressure system was moving slowly through Eastern Oklahoma into Western Arkansas during the afternoon hours of May 16th. A lone supercell thunderstorm across North Central Texas developed during the late morning hours of May 16th. This storm developed in a strongly sheared environment which allowed the storm to sustain itself. The storm moved south and east towards a strong instability axis which was oriented across Northeast Texas into Northwest Louisiana. With strong heating, strong instability developed and the supercell thunderstorm intensified as it moved south and east. The storm produced several tornado tracks, some of which occurred in Harrison County Texas and other into Southwest Caddo Parish and Northern Desoto Parish. The storm was a prolific hail and wind producer as well with wind gusts near 100 mph south of Shreveport, Louisiana with large fields of hail which turned numerous acres of land completely white.
