DISCUSSION...Isolated high-based thunderstorms are evolving along a northeast/southwest-oriented surface boundary/wind shift extending from northwest KS into east-central CO this afternoon. Downstream of these storms, deep inverted-V profiles (around 65 deg T/Td spreads) will be favorable for isolated severe downbursts, despite the presence of weak buoyancy. Around 25-30 kt of west-northwesterly steering flow (per the GLD VWP) will allow this activity to continue spreading into western KS, where a continued risk of locally severe wind gusts will persist this afternoon. ..Weinman/Hart.. 08/08/2026 ...Please see www.spc.noaa.gov for graphic product...
