Event Summary

The tornado started along Smith Lane just north of Stowey Parkman Road. The tornado moved northeast, snapping and uprooting a number of trees and causing some minor damage to structures as it passed across Wiley Dyess Road and TW Bass Road. The tornado reached its maximum intensity as it moved along and across Green Creek Road and Carson-Bunker Hill Road. Here two well built brick frame homes were heavily damaged, power poles were snapped, a well built farm building was destroyed, another outbuilding was destroyed, extensive tree damage occurred and several other homes and buildings suffered minor to moderate damage. The tornado weakened and crossed Hunnicut Road snapping a few trees where it crossed the road and dissipated before reaching State Highway 42 west of Bassfield.

Radar - Jefferson Davis County Tornado

 

Thanks to recent dual-pol upgrades at area Doppler radar sites, we could also confirm the presence of tornadic debris. Here is a screen capture from the Brandon, MS radar at 10:40 pm as the tornado was moving just west of Bassfield. The more traditional radar products shown at the top (base reflectivity, storm relative velocity) were showing a severe thunderstorm, with strong and tight rotation at just over 4,000 feet above the ground. It was the dual-pol products on the bottom of this image that provided additional confirmation that this rotation must have been extending to the ground. The correlation coefficient (CC) product in the bottom-right helps to provide an idea of the consistency of the shape of the targets being reflected back to the radar. Higher values shows greater consistency (for instance, all rain), while lower values show less consistency (a mixture of targets). In this image we see an area of lower CC, which is actually an indication of tornadic debris of various shapes and sizes. Dual-pol continues to prove to be a powerful tool in our arsenal of technology enabling us to track severe weather.
