Fourth tornado watch issued ... this one for northern Alabama to the north of Birmingham and for Tennessee south of Nashville. It includes Huntsville. Watch is in effect until midnight.
Please note that strong storms continue southwest into Louisiana. If you scroll down, you'll see all four tornado watches which all remain in effect.
There is some possibility the tornado threat will continue overnight. It is possible additional watches will be issued.
However, it has been a long day and this is the last blog update on these storms. However, I may continue to post on Twitter @usweatherexpert . Please keep up on the weather and have a safe night.
ADDITION: 7:12pm. The overnight tornado forecast from SPC continues to be rather ominous.
