   The severe weather threat for Severe Thunderstorm Watch 279, 282
   continues.

   SUMMARY...The potential for hail and damaging gusts continues. The
   severe risk is likely to focus near a remnant boundary this evening.

   DISCUSSION...Across WW282, several severe storms, including
   supercells and clusters, have matured this evening. Much of the
   stronger convection has been focused along the remnant baroclinic
   zone from the morning storms from northern and eastern OH, into far
   southwestern PA and northern WV. To the west, earlier convection and
   cloud debris has largely stabilized the air mass. This trend is
   likely to continue as the remaining storms gradually consolidate
   into one or more clusters. Buoyancy is slowly weakening with the
   loss of diurnal heating, but remains sufficient for supercells given
   robust deep-layer shear. Overall the severe risk for hail, and
   damaging gusts should continue with the strongest storms over the
   next couple of hours. However, a gradual weakening trend is expected
   after sunset as inhibition increases into tonight.
