The northern watch includes Nashville.
The southern of the two watches is a particularly dangerous situation watch -- which is a rare category of tornado watch issued when violent tornadoes are possible.
As of this posting, 4:36pm CDT, the radar below shows the first tornado warning of the day in northeast Mississippi to the northeast of Tupelo (red polygon).
Please keep up on local weather information. This will be the only update now that the storms are in progress.
