   The severe weather threat for Severe Thunderstorm Watch 659
   continues.

   SUMMARY...Some severe threat will persist for a few more hours in
   and immediately surrounding Severe Thunderstorm Watch 659. Damaging
   gusts remain the primary concern.

   DISCUSSION...A pronounced cold pool, originating from a mature
   persistent elongated convective system, has surged southeastward
   across Lake Erie over the past couple of hours. At least a few
   severe gusts have been observed, and some convective rejuvenation
   has occurred along the cold pool leading edge. Buoyancy
   decreases/MLCINH increases with eastward and southward extent ahead
   of the ongoing storms/cold pool. However, the fast pace of the cold
   pool suggests that continued cellular regeneration and accompanying
   damaging wind gust potential will continue for at least a couple
   more hours.
