Two supercell storms tonight are entering West Alabama’s Pickens County.
One is passing near Memphis, Alabama. The other is back near DeKalb MS.
Both contain possible tornadoes.
A tornado warning has been issued until 11 p.m.
The environment over Northwest Alabama is very conducive to tornado development tonight. While there is not lots of instability, there is enough for thunderstorm updrafts, so lots of lightning. High winds aloft are brought down to the surface by these updrafts, so damaging winds are likely. And high amounts of wind shear allow storms like these to become organized and the spin can lead to tornadoes.
