   Mesoscale Discussion 0768
   NWS Storm Prediction Center Norman OK
   0706 PM CDT Thu May 18 2017

   Areas affected...Northeast KS and northwest MO

   Concerning...Tornado Watch 238...239...

   Valid 190006Z - 190130Z

   The severe weather threat for Tornado Watch 238, 239 continues.

   SUMMARY...Threat for tornadoes will continue across northeastern KS
   for the next few hours.

   DISCUSSION...Recent radar imagery shows four supercells west of TOP
   along the warm front extending from just south of MKC westward
   through TOP and SLN and then southwestward through DDC. Despite a
   messy storm mode, these storms intensified over the past hour or so
   and each exhibited strong low-level rotation. Most recent velocity
   data have shown more outflow-dominant signatures with some weakening
   noted with the two westernmost storms, particularly with the storm
   over Ottawa and Saline counties which has weakened significantly as
   a result of destructive storm interaction. The storms farther east
   over Wabaunsee and Shawnee counties remain quite strong and
   strengthening low-level flow coupled with enhanced vorticity along
   the warm front will continue to support a tornado threat.
