Exact storm evolution is uncertain, but watch issuance may be needed if intensification occurs. DISCUSSION...Latest GOES imagery and lightning data show the development of elevated thunderstorms over far northwest MO on the eastern fringe of a plume of steeper (7-8 C/km) mid-level lapse rates and within a zone of focused isentropic ascent between 925-850 mb. Although these storms are currently elevated, recent forecast soundings suggests that lingering MLCIN will be increasingly diminished as surface temperatures approach the low 90s. As such, it is possible that this activity gradually becomes surface based over the next 1-2 hours through peak heating and begins to fully realize the 2000-2500 J/kg MLCAPE environment. GOES visible imagery and derived wind products also show strong directional and speed shear across the region, which should aid in storm organization and intensification - likely into supercells with an attendant threat for severe winds and large hail - if storms can be maintained. While exact convective evolution is uncertain, watch issuance may be needed if storms begin to intensify and pose a more robust severe threat into northern MO. ...Moore/Smith.. 07/19/2025 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!_klXAbG_-LPtMDdRdAnTsP_hhzhqJdKOB29bjdjOnMar-rHJQz967araK4BmQSgoFQDCv8l74= R9pLBP_an7ZPplfE6c$ for graphic product...
