   The severe weather threat for Severe Thunderstorm Watch 238

   SUMMARY...Some severe threat continues across portions of Severe
   Thunderstorm Watch 0238, predominantly with a supercellular
   convective cluster north of Lubbock, Texas. Otherwise, the severe
   threat is expected to diminish with the onset of nocturnal cooling
   and deep-moist convective mixing of the troposphere.

   DISCUSSION...The severe threat continues across portions of Severe
   Thunderstorm Watch 0238, particularly in the vicinity of Hale
   County, north of Lubbock, where a tornado was reported with a
   rightward moving, dominant supercell. This supercell originated from
   a northward propagating convective cluster, with a defined outflow
   boundary. Along and north of this outflow boundary, new cellular
   development has been noted. A few of these newer storms may pose a
   short term severe hail threat, and perhaps some risk for damaging
   wind gusts. 

   Otherwise, much of the airmass has overturned across Severe
   Thunderstorm Watch 0238 by earlier rounds of vigorous convection.
   Given that peak heating has already passed for the area, and given
   the decrease in the cumulus field behind the earlier convection, it
   appears that the primary severe threat will remain with the storms
   immediately north of Lubbock, with an overall decrease in convective
   intensity expected as storms move east of Severe Thunderstorm Watch
   0238, and with the onset of nocturnal cooling/boundary layer
