   Valid 280654Z - 280800Z

   The severe weather threat for Tornado Watch 154, 155 continues.

   SUMMARY...Greatest severe potential is expected across southwest
   Missouri in the short term. Overall risk is diminishing with
   northward extent.

   DISCUSSION...Outflow associated with convection across central MO
   into west-central IL is outpacing convection over the past hour or
   two. This, coupled with increasing low-level
   inhibition/boundary-layer stabilization is largely limiting severe
   potential. As a result, Tornado Watch 154 will be cancelled early
   per collaboration with WFO LSX.

   Further southwest, a more mature/organized QLCS over northeast OK
   will spread into southwest MO. While weak low-level inhibition is
   present, stronger ascent and more favorable low-level shear may
   still support a tornado and damaging wind risk over the next couple
   of hours, especially across southern portions of Tornado Watch 155.
