A cold front shifted south and became stationary across portions of Deep East Texas and the southern and eastern sections of Northcentral Louisiana during the afternoon hours of March 28th. A warm and unstable air mass was present near and south of the front, as a large upper level trough shifted east across Texas during the evening and overnight hours, taking on a negative tilt as it entered the region late. Showers and thunderstorms developed throughout the day on March 28th across much of East Texas and North Louisiana ahead of this trough, with surface low pressure developing along the front over Northcentral Louisiana. The combined instability and increased wind shear near and south of the front resulted in severe thunderstorm development, producing numerous reports of damaging winds and and a couple of isolated tornadoes during the afternoon. Additional thunderstorms intensified during the evening and overnight hours along and south of the front ahead of the approaching upper trough, with periods of heavy rainfall training over the same areas, resulting in flash flooding over portions of Northcentral Louisiana. These storms diminished during the early morning hours of March 29th with the passage of the trough.
