   Concerning...Severe Thunderstorm Watch 129...

   Valid 190408Z - 190615Z

   The severe weather threat for Severe Thunderstorm Watch 129
   continues.

   SUMMARY...The damaging-wind threat continues, but should become
   increasingly isolated with time.

   DISCUSSION...A well-organized QLCS is moving quickly across southern
   IN and northern KY late tonight, with recent observed wind gusts of
   35-45 kt. While some weakening has been noted compared to earlier
   this evening, convection is still keeping pace with the gust front
   along the north-south oriented portion of the QLCS, and some
   damaging-wind threat will near the edge of WW 129 by 05 UTC.
   However, downstream instability is quite weak, and convective
   intensity should continue to generally weaken with time, resulting
   in an increasingly isolated/marginal severe threat into the early
   overnight hours. As a result, while local watch extension of WW 129
   may need to be considered (depending on observational trends),
   downstream watch issuance is currently considered unlikely.
