   Areas affected...portions of central Illinois

   Concerning...Severe potential...Watch unlikely 

   Valid 110659Z - 110830Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Numerous thunderstorms may remain capable of isolated
   severe gusts or marginally severe hail for a couple more hours. A
   new WW is unlikely.

   DISCUSSION...Scattered to numerous thunderstorms remain ongoing
   across portions of central IL as of 0655 UTC. Several multicells
   within an east-west oriented cluster have shown occasional stronger
   updrafts and reflectively cores over the last hour. This could
   continue for a few more hours this evening as the environment
   remains generally unstable and moderately sheared, favoring some
   organized storm potential. Additional loosely organized linear
   storms are approaching from western MO. This could support isolated
   severe gusts and perhaps marginally severe hail for a couple hours
   across central IL. However, increasing nocturnal inhibition and
   general organization trends suggest a slow weakening is likely.
   Thus, while isolated severe remains possible, a new WW is not
   expected.
