   Areas affected...southeastern Missouri...southern Illinois...and
   western Kentucky

   Concerning...Severe Thunderstorm Watch 624...

   Valid 160013Z - 160145Z

   The severe weather threat for Severe Thunderstorm Watch 624
   continues.

   SUMMARY...Local risk for hail and damaging outflow wind gusts
   continues.

   DISCUSSION...Latest radar loop shows that storms evolving across the
   southern Illinois vicinity have decreased slightly in
   organization/intensity over the past hour or so, with the strongest
   storm now moving southeastward toward/into Union County Illinois. 
   At this point, storms appear to be largely multicellular, and should
   remain so over the next couple of hours, as convection persists
   within the axis of moderate instability roughly centered over the MS
   River Valley.  Marginally severe hail/wind will likely remain the
   primary severe risks the remainder of the evening.
