Summary

An unstable atmosphere developed across Southeast Texas and Southwest Louisiana during April 2nd in advance of an approaching low pressure system. A supercell thunderstorm developed during the early morning hours over Acadiana that produced widespread large hail and two tornadoes between Lafayette and Breaux Bridge. A second supercell developed in the afternoon and produced three tornadoes along Highway 165. The approaching cold front triggered multiple rounds of thunderstorms that trained over Vernon and Rapides Parishes during the evening of April 2nd. A widespread 8 to 11 inches of rain fell during a six hour period which produced flash flooding. The runoff from this heavy rainfall fed into local area rivers and produce moderate to major flooding downstream over the next several days.
