   Areas affected...Portions of central and eastern Missouri

   Concerning...Tornado Watch 18...

   Valid 070408Z - 070515Z

   The severe weather threat for Tornado Watch 18 continues.

   SUMMARY...Organized thunderstorms will spread east of Tornado Watch
   018 in the next 1-2 hours. New severe thunderstorm watch is being
   considered downstream.

   DISCUSSION...Elongated band of convection has gradually organized
   over the last few hours, currently extending from northeast OK into
   central MO. While a few supercells are noted, especially over
   northeast OK, some bowing of the squall line is occurring over
   Camden/Laclede County. This portion of the line is beginning to
   surge a bit and damaging winds may become more common as this
   activity spreads into east-central MO. New severe thunderstorm watch
   is being considered to account for this evolution.
