Occasional Strong Downbursts Possible Over Parts of North/Central Alabama

| July 31, 2020 @ 1:32 pm

SUMMARY…Thunderstorms are developing in a highly unstable environment. Atmospheric conditions will support the occasional strong downburst capable of producing isolated wind/tree damage.

DISCUSSION…Thunderstorms continue to develop on the far southern periphery of a mesoscale convective vortex across Tennessee. These thunderstorms are developing within a strongly unstable environment with just enough deep-layer flow to support updraft longevity.

Given high tropospheric moisture content, strong instability, and deep-layer shear around 20 knots, a few downbursts cannot be ruled out with the strongest thunderstorm cores. The lack of stronger deep-layer shear should preclude a more widespread, organized severe risk and therefore a watch is not currently anticipated. Trends will continue to be monitored.
