   Valid 290038Z - 290145Z

   The severe weather threat for Tornado Watch 71 continues.

   SUMMARY...New Tornado watch will likely be warranted soon, extending
   east of ww71.

   DISCUSSION...Large-scale height falls and strengthening wind fields
   appear to be aiding an elongated corridor of convection that
   currently stretches from southern IL-along the MS River-northern LA.
   With time a squall line should mature and move steadily east across
   the lower OH Valley/Mid-South Region. Of some concern is the
   pre-squall line activity that is spreading across the TN/KY border,
   southwest of HOP. This activity should approach the eastern edge of
   ww71 within the hour. 00z soundings from BNA, and especially JAN are
   notably capped with significant inhibition. This suggests
   warm-sector development may struggle south of the KY border until
   boundary layer moistens and/or 700mb temperatures cool. Some cooling
   is expected later this evening but the primary storm mode may be an
   upward-evolving squall line. Even so, a few discrete supercells will
   likely spread across western KY ahead of the main line. As a result,
   a new tornado watch may be warranted soon to account for this
   threat.
