00:00 A tornado warning has been issued to the south of Memphis.
00:03 I'm in Hernando right now in Mississippi and you can see the clear blue skies here.
00:08 Listen to the tornado siren sounding.
00:11 That's the direction that the storm is approaching from.
00:13 You can see that dark sky there.
00:15 The storm is crossing the Mississippi River right now and moving into an environment that
00:19 is supportive of tornadoes.
00:21 There's a pretty strong low-level wind shear in place.
00:24 You can see a mid-level dry slot that has carved out a lot of the cloud cover.
00:27 We have a little bit more instability further south on the tail end of this front.
00:32 This is a very mature supercell.
00:33 You can see the anvil coming in over top.
00:35 That's the top of the storm right there.
00:37 The anvil clouded.
00:38 You can trace it all the way back to the updraft of this storm and that's where the tornado
00:42 would be located.
00:43 It's crossing the Mississippi River right now near Tunica where all those casinos are
00:47 located just to the southwest of Memphis.
00:50 Definitely need to get to a safe place so this storm is heading in the direction of
00:53 Holly Springs eventually toward the Tennessee/Mississippi border.
00:57 But this storm is a hard right mover, moving almost due east, which means that it's carving
01:02 right into that low-level jet at an angle and that means that it has the potential of
01:06 producing at least an isolated tornado, possibly even a long-track tornado or two.
01:11 [Sounds of a storm moving]
