EF1 tornado in Pike County, Mississippi

A strong EF-1 tornado touched down south of Hwy 570 near Moak Rd in Pike County, MS. This tornado rapidly strengthened and grew in size as it tracked to the east-northeast causing destruction of a wood frame farm outbuilding and increasingly significant treefall as it crossed Kodiak Ln and Magnolia Pisgah Rd. While there was a high proportion of treefall associated with this tornado in this area, a significant portion was due to uprooted trees from soft soils due to recent heavy rainfall. As such, maximum sustained winds were estimated near 110 mph despite the heavy deforestation. This level of heavy deforestation spanning approximately 375 yards wide at peak width continued across Hwy 570 to Dye Ln where tree damage rapidly became less significant. It's estimated that this tornado rapidly lifted as it crossed Magee Rd.

Environmental conditions favorable for a QLCS (Quasi-Linear Convective System) tornado event developed across southeast Louisiana and southern Mississippi during the afternoon and evening hours of March 11th. An upper-level storm system moving east from Texas overspread a very moist and increasingly unstable air mass in place across the region. At the same time, intense low-level wind shear and strong atmospheric spin developed as southerly winds strengthened ahead of an approaching line of storms with bowing segments.

The combination of rich Gulf moisture, strong low-level atmospheric spin, and a fast-moving line of thunderstorms created an environment supportive of embedded rotating circulations along the leading edge of the QLCS. As that line moved west to east across the local area, several rapidly developing tornadoes formed within these circulations. A total of 6 tornadoes were confirmed across southwest Mississippi and multiple reports of damaging straight-line winds were also received.
