Storm coverage may remain too limited for a watch, though trends are being monitored. DISCUSSION...Within a zone of broadly confluent low-level flow across parts of southwestern NE, diurnal heating amid lower 60s dewpoints has aided in the development of isolated thunderstorms this afternoon. A long/straight hodograph (around 35-40 kt of effective shear) and steep midlevel lapse rates/moderate surface-based buoyancy may continue to promote splitting supercells and a risk of large hail and locally severe wind gusts. Given minimal large-scale forcing for ascent, overall storm coverage may remain too limited for a watch. However, given the favorable environment and ongoing mode evolution, trends are being monitored. ..Weinman/Smith.. 08/26/2026 ...Please see www.spc.noaa.gov for graphic product...
