Thunderstorm Wind in Elmore County, Alabama

Multiple trees and power lines were downed across Elmore County.

A potent shortwave trough dove southeastward from Missouri into the Tennessee Valley during the day and evening of April 10. Storms began firing over West Tennessee during the afternoon, moving southeasterly in conjunction with northwest flow aloft. Meanwhile, a pre-existing boundary was draped across north central Alabama, leftover from convection over Tennessee that morning. More storms began firing along this boundary during the late afternoon and evening hours, initially posing a hail threat. Up to golf ball-size hail fell across Etowah, Cherokee, and Blount counties, with steep mid-level lapse rates in place. Storms later grew upscale into a wind threat by sunset, with scattered pockets of wind damage across several counties.
