   The severe weather threat for Severe Thunderstorm Watch 509
   continues.

   SUMMARY...Damaging wind threat continues this evening.

   DISCUSSION...MCS that developed over south-central NE has matured as
   it propagates east along the NE/KS border toward southwest
   IA/northwest MO. Latest diagnostic data depicts a broad reservoir of
   buoyancy (1000-1500 MLCAPE) that has yet to be overturned
   immediately ahead of this complex. With the LLJ beginning to
   strengthen over northeast KS there is reasonable confidence this MCS
   should advance beyond the MO River before any appreciable weakening
   occurs. Damaging winds are the primary risk with this convection.
