   Areas affected...portions of southern Kentucky into northern and
   Middle Tennessee

   Concerning...Tornado Watch 315...

   Valid 261857Z - 262030Z

   The severe weather threat for Tornado Watch 315 continues.

   SUMMARY...The severe threat continues across Tornado Watch 315.
   Damaging gusts will be the main threat, and a tornado cannot be
   ruled out. Severe weather is most likely wherever thunderstorms can
   ingest the warmer airmass. Local spatial and temporal extensions of
   Tornado Watch 315 may be necessary.

   DISCUSSION...While the earlier QLCS recently progressed out of
   Tornado Watch 315 (into eastern KY), a second line of thunderstorms
   continues to move east-southeast over southern KY into northern and
   middle TN. This line of storms is trailing the previous QLCS, atop a
   cooler and stable airmass. Much of this line may remain on the cool
   side of the baroclinic zone, with limited severe potential. However,
   the southern flank of the line may interact with the baroclinic
   boundary and potentially ingest surface-based air parcels. Should
   this occur, damaging gusts will be possible and a tornado cannot be
   ruled out. 

   Tornado Watch 315 expires at 2000Z, so a temporal extension of the
   watch may be needed. A spatial extension of the watch may also be
   needed if the line of storms can build farther south.
