The episode as NWS JAX wrote it up.
A mid level trough axis extended down the Appalachian spine and into the lower Mississippi River Valley which provided a west to southwest steering flow over the local area. Precipitable water amounts were near 2 inches with 500 mb temperatures ranging from -8 degrees C to -10 degrees C. Scattered severe storms developed during the afternoon and evening along the sea breeze fronts.
