   Areas affected...Central MO

   Concerning...Tornado Watch 248...

   Valid 192304Z - 200030Z

   The severe weather threat for Tornado Watch 248 continues.

   SUMMARY...Isolated damaging wind gusts and/or a brief tornado remain
   possible for the next hour or so but a gradually diminishing severe
   threat is anticipated.

   DISCUSSION...Well-developed MCV and an associated line of storms
   continues to move northeastward across central MO. Recent radar
   imagery has shown decreasing storm intensity within the line but
   more cellular activity has developed ahead of the line. Some brief
   strengthening and/or forward propagation of the northern portion of
   the line is possible as it interacts with this more cellular
   activity and/or the warm front extending across the region. However,
   after this brief intensification, the gradual diminishing trend
   noted over the past hour or so is expected to continue as the line
   continues into a less favorable thermodynamic environment
   characterized by temperatures in 60s and MLCAPE less than 1000 J/kg.
   Given the strength of the flow aloft and potential enhancement of
   the low-level wind fields by the MCV, some isolated damaging wind
   gusts and possibly a tornado are still possible but the overall
   severe threat appears to be diminishing.
