   The severe weather threat for Severe Thunderstorm Watch 399
   continues.

   SUMMARY...Convection should increase across ww399 this evening along
   with an attendant severe risk for wind/hail.

   DISCUSSION...Weak short-wave ridging is expected to gradually relax
   this evening. This is supported by a recent uptik in convection
   south of a weak surface boundary that is currently draped east-west,
   just south of I70. Visible satellite imagery depicts a considerable
   amount of agitated cu from southeast KS into south-central MO where
   several robust thunderstorm clusters are maturing. This activity is
   evolving within a very unstable air mass, and cloud tops suggest
   these updrafts are processing air efficiently. Current thinking is a
   considerable amount of convection may ultimately evolve across ww399
   and large hail and damaging winds are possible with these storms.
