A new Tornado Watch is likely needed. DISCUSSION...A robust cluster of storms is organizing west of a strongly sheared and destabilizing air mass across parts of southern OK and western North TX. While predominately linear, these storms are moving into a modified warm frontal zone with strong low-level effective helicity (0-1 km >350 ms2/s2 from the TLX VAD) sufficient for tornadoes. Diffuse heating and subtle confluence are also apparent ahead of the QLCS across western north TX. Hi-res guidance and observational trends suggests additional, more discrete, storms may develop/mature this afternoon. With moderate buoyancy and large-low level hodograph curvature, supercells and QLCS mesovorticies with the potential for tornadoes could materialize. A Tornado watch is likely. ..Lyons/Hart.. 11/03/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SHV...TSA...FWD...OUN...
