Mesoscale Discussion 1442 NWS Storm Prediction Center Norman OK 0500 PM CDT Wed Jun 25 2025 Areas affected...portions of southeast Minnesota...extreme northeast Iowa...and far southwestern Wisconsin Concerning...Tornado Watch 461... Valid 252200Z - 252330Z The severe weather threat for Tornado Watch 461 continues. SUMMARY...A tornado and severe gust risk will continue with ongoing storms. The best chance for tornadoes will exist with low-topped supercells traversing a diffuse baroclinic boundary. DISCUSSION...Multiple low-topped supercells have developed and are traversing a diffuse west-to-east baroclinic boundary, where strong low-level shear is in place. The most recent ARX VAD shows a sizeable, curved hodograph and nearly 200 m2/s2 in the surface-500 m layer. As such, tornadoes and severe gusts remain a concern with the stronger storms, particularly with any low-topped supercells that continue to traverse the boundary, where maximum ingestion of streamwise vorticity may be realized. ..Squitieri.. 06/25/2025 ...Please see www.spc.noaa.gov for graphic product...
