MD 0561 CONCERNING TORNADO WATCH 155... FOR WESTERN OKLAHOMA INTO SOUTHERN KS Mesoscale Discussion 0561 NWS Storm Prediction Center Norman OK 0117 AM CDT Mon Apr 27 2026 Areas affected...Western Oklahoma into southern KS Concerning...Tornado Watch 155... Valid 270617Z - 270715Z The severe weather threat for Tornado Watch 155 continues. SUMMARY...The threat for an isolated supercell remains along the warm front into southeast Kansas, while the severe threat is diminishing to the southwest into Oklahoma. DISCUSSION...The primary mid-upper jet is ejecting east-northeastward from the TX Panhandle toward KS, and an associated surface cyclone in the eastern OK Panhandle will likewise continue to develop east-northeastward. South of the cyclone track and beneath the jet core, veering of low-level flow to more westerly will continue across western and northern OK, with rapid drying expected above the surface. Despite the remaining near-surface moisture and associated buoyancy, the drying above the surface and a fairly warm elevated mixed layer suggest that additional storm development is unlikely into northwest OK. Meanwhile, some potential for isolated supercell development will persist in the short term along the warm front into southeast KS, where VWPs show very large/curved hodographs coincident with upper 60s boundary-layer dewpoints. ..Thompson.. 04/27/2026 ...Please see www.spc.noaa.gov for graphic product...
