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.
