PDS tornado watch ongoing for TN valley

Not related to Michigan, but this is of particular concern considering the circumstances. A relatively rare type of tornado watch with the enhanced wording "Particularly Dangerous Situation" has been issued for portions of four states to our south.

These types of watches are usually issued when a major tornado outbreak is expected or occurring, with EF4 and EF5 tornadoes not only possible but likely. Essentially, those in the affected counties should treat this as a high risk day at this point. If you have relatives or friends in the area, urge them to treat this situation with extraordinary care. Lives can and will be lost in these types of situations.
