MD 0768 CONCERNING TORNADO WATCH 238…239… FOR NORTHEAST KS AND NORTHWEST MO
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. ..Mosier.. 05/19/2017 ...Please see www.spc.noaa.gov for graphic product...
