Afternoon weather update

We have some very isolated showers popping up across southwest Middle TN this afternoon. A couple of them may sneak up on us on the plateau as we go through the rest of the day. Most of us will stay dry.

The active weather can be found all around the Southeast. On the map below, I drew the flow around the center of high pressure on the Gulf Coast. The flow around this high keeps storms away from us, riding the ridge around it. Air sinks under high pressure, suppressing cloud development. The air then has to rise again and it will do so around the edge of the high. Rising air cools and condenses in our atmosphere, creating unsettled conditions.

Finally, I wanted to share with you a photo that I have been sharing on social media. It’s one of the best pics of a supercell that I have ever seen. It was taken in Dora, New Mexico on Sunday. You can just see the storm spiral upward. Notice the tornado at the base of the storm. Storms in the southwestern U.S. and the northern plains tend to have less precip associated with them, making the storm much more visible.
