If skies are clear, SWPC said the northern lights could be visible as far south as Alabama and northern California.

A geomagnetic storm is coming and with it brings the chance of seeing the aurora borealis further south than normal. Will we see it in Tennessee?

The geomagnetic storm is expected to be a G4 class, according to the scale used by the U.S. National Oceanic and Atmospheric Administration (NOAA)'s Space Weather Prediction Center (SWPC). This is the second-highest level on the SWPC scale used to measure geomagnetic storms.
