Valid 171018Z - 171145Z The severe weather threat for Severe Thunderstorm Watch 24 continues. SUMMARY...An isolated large hail and strong/gusty wind threat continues across Severe Thunderstorm Watch 24. DISCUSSION...A messy, cluster storm mode has developed across northeastern OK into southeastern KS and southwestern/west-central MO. This convection will likely remain elevated this morning to the north of a surface boundary. Although storm mode is not overly favorable, occasional marginally severe hail will remain possible along an elevated instability gradient (MUCAPE 1000-2000 J/kg). Isolated strong/gusty winds may also occur as individual cells develop northeastward. Recently, additional convection has begun to develop farther south into northeastern OK along a low-level warm advection wing and where surface dewpoints are slightly higher (generally mid to upper 50s). It remains to be seen whether storms will be able to strengthen south of the ongoing band. If they do, then all severe hazards, including a brief tornado, would be possible. ..Gleason.. 03/17/2021 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SGF...EAX...TSA...ICT...
