Mesoscale Discussion 1192 NWS Storm Prediction Center Norman OK 0700 PM CDT Sat Jul 11 2020 Areas affected...Southeat KS...Southwest MO...Northeast OK...Northwest AR Concerning...Tornado Watch 358... Valid 120000Z - 120130Z The severe weather threat for Tornado Watch 358 continues. SUMMARY...Severe thunderstorms will sag south into northeast Oklahoma over the next hour. Hail and wind can be expected. DISCUSSION...Thunderstorm updrafts are gradually strengthening/deepening within an expanding cluster over southeast KS. This activity has drifted south along the eastern edge of an intense instability plume characterized by 5000-6000 J/kg MLCAPE. Earlier updrafts struggled a bit across east-central KS, but cloud top venting appears stronger over the last hour or so. Additionally, very large hail is likely occurring with these storms. There is increasing confidence that an expanding cluster of storms will emerge, along with a possible notable cold pool. If so, at some point the forward propagation may begin to increase and the wind threat would necessarily increase as well. Local watch extension, or a new watch, may be needed across eastern OK and northwest AR. ..Darrow.. 07/12/2020 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SGF...TSA...ICT...
