   Areas affected...Extreme southeast MO...southern IL...southwest IN

   Concerning...Severe Thunderstorm Watch 65...

   Valid 280102Z - 280230Z

   The severe weather threat for Severe Thunderstorm Watch 65
   continues.

   SUMMARY...A localized hail risk may persist with the strongest
   cells, but watch issuance downstream of WW 65 is not currently
   anticipated.

   DISCUSSION...The earlier intense elevated supercell that produced
   significant hail over parts of southern MO has weakened
   substantially in the past hour. Convection continues to occasionally
   flare up on the southern edge of the remnant cluster as it moves
   into southern IL, and some hail potential will persist with the
   strongest cells, given MUCAPE of 1000-1500 J/kg and effective shear
   in excess of 30 kt. However, reintensification of the ongoing
   cluster is not currently anticipated. WW 65 will likely be cancelled
   early and downstream watch issuance is not currently anticipated.
