Mesoscale Discussion 1460 NWS Storm Prediction Center Norman OK 0429 PM CDT Thu Jun 26 2025 Areas affected...portions of eastern Kansas into far northwestern Missouri Concerning...Severe potential...Watch unlikely Valid 262129Z - 262300Z Probability of Watch Issuance...20 percent SUMMARY...Scattered strong thunderstorms may pose an occasional severe gust threat through the remainder of the afternoon. DISCUSSION...Multiple thunderstorms have matured along a confluence zone across eastern KS, where MRMS mosaic radar imagery depicts 50+ dBZ echoes well exceeding 30 kft. While vertical wind shear is weak, these storms are developing atop a moist surface airmass, characterized by 70+ F surface dewpoints. Given a well-mixed boundary layer, 8 C/km low-level lapse rates are in place, boosting MLCAPE to 3000 J/kg. As such, the stronger pulse-cellular and multicellular storms will be capable of producing wet downbursts and associated strong wind gusts. However, the overall severe threat should remain isolated. ..Squitieri/Guyer.. 06/26/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SGF...EAX...TOP...ICT...
