ACUS11 KWNS 132054 SWOMCD SPC MCD 132053 KSZ000-132300- Mesoscale Discussion 0404 NWS Storm Prediction Center Norman OK 0353 PM CDT Mon Apr 13 2026 Areas affected...portions of eastern Kansas Concerning...Severe potential...Watch unlikely Valid 132053Z - 132300Z Probability of Watch Issuance...20 percent SUMMARY...Isolated thunderstorms may develop along a dryline across portions of eastern Kansas this afternoon/evening. Any storms that do develop will bring a threat for all hazards, with the main threat large to very large hail. DISCUSSION...Latest visible satellite imagery depicts an area of deepening cumulus along a dryline in the vicinity of Wichita, Kansas. Ahead of this dryline, surface temperatures in the mid-80s and dewpoints in the mid-60s F are contributing to 2000-2500+ J/kg MLCAPE within the warm sector. Steep mid-level lapse rates (evident on the 18Z LMN special sounding), elongated hodographs (effective bulk shear of 30-35+ kts per latest mesoanalysis), and ample buoyancy within the hail growth zone will support the potential for large to very large hail to 3+ inches in diameter with any storm that does develop. The tornado threat remains somewhat more conditional on a storm persisting into the evening hours when a strengthening nocturnal low-level jet will support increasing low-level hodograph curvature and an accompanying increase in the tornado threat for any ongoing supercells. Watch issuance appears unlikely at this time owing to uncertainty regarding the occurrence of convective initiation. Trends will be closely monitored and a watch may be needed should initiation appear imminent given the conditionally favorable environment. ..Chalmers/Hart.. 04/13/2026 ...Please see www.spc.noaa.gov for graphic product...
