   The severe weather threat for Severe Thunderstorm Watch 246

   SUMMARY...The severe threat continues across Severe Thunderstorm
   Watch 246, with large hail and severe gusts the main threats. Narrow
   corridors of focused severe wind swaths, perhaps with a
   hurricane-force gust or two, remains possible over the next few

   DISCUSSION...Several multicellular thunderstorm clusters have been
   oscillating in intensity for the past few hours, with some storms
   having a history of severe hail. So far, one severe wind report was
   received, which was a measured 78 mph wind gust near Plainview, TX.
   A particularly strong cluster of thunderstorms over Dallam County,
   TX continues to progress eastward amid a relatively undisturbed
   airmass, where some of the latest Warn-On-Forecast guidance depicts
   a focused corridor of severe gusts. Forecast soundings show a deep
   boundary layer beneath tall and thin CAPE profiles where storms have
   yet to overturn the ambient airmass. As such, storms should continue
   to percolate in intensity and potentially produce more instances of
   severe hail and wind over the next few hours.
