Lack of organization should preclude watch issuance this afternoon. DISCUSSION...Convection over the course of the last couple of hours has remained rather weak with a few cells becoming briefly marginally severe. Area VAD data shows 0-6 km shear of 15-20 kt. This should continue to promote disorganized cells that may occasionally pulse in intensity. A corridor of low 90s F temperatures and steeper low-level lapse rates in northern Georgia into Upstate South Carolina could see a locally greater risk of isolated wind damage. Barring greater cold pool organization of activity, a watch is not anticipated this afternoon. ..Wendt/Thompson.. 07/19/2026 ...Please see www.spc.noaa.gov for graphic product...
