EF2 tornado in Lafayette County, Mississippi

The tornado formed along Highway 331 between the communities of Cornish and Tula, producing minor tree damage. The tornado quickly intensified as it crossed U.S. Highway 278 near Lafayette Springs, snapping numerous power poles and trees, and causing minor roof damage along County Roads 431 and 284. This damage was consistent with EF2 wind speeds near 120 mph before crossing into Pontotoc County.

The front eventually sagged south back into the Mid-South during the early morning hours of April 5th. Strong low-level moisture transport into the frontal zone resulted in heavy rain and training storms across northern sections of the Mid-South, mainly north of I-40. A bow echo developed along and just south of the slowly advancing front. This feature crossed the entire forecast area producing 13 tornadoes, including an EF-2, and wind damage. Heavy rain continued through the morning hours with flash flooding increasing across the Mid-South.

The final round of severe weather occurred during the afternoon and evening of April 5th. The slow-moving cold front combined with an increasingly unstable airmass, strong upper-level divergence, and 0-6 km bulk shear values of 50-60 knots provided the ingredients for more severe storms. A QLCS with a bookend vortex pushed into east Arkansas and West TN with a good deal of wind damage. The southern end of the line became more supercellular during the afternoon and evening and produced seven tornadoes, including an EF-2. The combination of continued abundant moisture with precipitable water values greater than 1.75 inches and strong low-level moisture transport into the frontal zone resulted in very heavy rainfall and considerable flash flooding across much of the Mid-South.

The severe weather threat finally wound down by late evening on April 5th with the flash flood threat ending a few hours later. Total rainfall amounts of 10-15 inches occurred across parts of east Arkansas, the Missouri Bootheel, West Tennessee, and extreme northwest Mississippi during this event. This resulted in widespread river flooding for several days following the event.
