   Concerning...Severe Thunderstorm Watch 610...

   Valid 220443Z - 220615Z

   The severe weather threat for Severe Thunderstorm Watch 610
   continues.

   SUMMARY...A localized severe threat may continue into the early
   overnight hours.

   DISCUSSION...A persistent storm cluster is moving
   south-southeastward across central IL late this evening. While this
   cluster has struggled to maintain severe intensity, MLCAPE of
   near/above 2000 J/kg and relatively enlarged low-level hodographs
   (with effective SRH of 150-200 m2/s2) may continue to support modest
   storm organization and transient rotation into the early overnight
   hours. This could support potential for localized wind damage for as
   long as this cluster remains vigorous, though a gradual weakening
   trend is eventually expected with time.
