Overview
- The NWS Storm Prediction Center issued Severe Thunderstorm Watch 666 for parts of southwestern and north-central Minnesota and eastern South Dakota and Watch 667 for southwest Kansas, much of Oklahoma and the Texas Panhandle on Saturday.
- SPC mesoscale discussions (notably MDs 2289–2291) highlighted southern Kansas into northern Oklahoma as the greatest near-term concern because storms could begin as supercells capable of 2+ inch hail then merge into clusters that produce 75+ mph gusts.
- Local outlets in Oklahoma reported a level 2 'slight' risk for northwest counties with a heightened threat of 70–80 mph wind gusts and golf‑ball-sized hail around towns such as Ponca City and Bartlesville, creating risk for outdoor events and travel disruptions.
- Other corridors carried lower or conditional risk: MD 2288 said extreme southeast Oklahoma and southern Arkansas faced only isolated damaging gusts with watches unlikely, and MD 2292 flagged a roughly 40% chance of a watch across parts of northeast Ohio and western New York with gusts up to about 60 mph.
- A Severe Thunderstorm Watch means conditions are favorable for severe storms and not all areas in a watch will be hit, so people in affected zones should monitor local warnings, plan to move indoors quickly if warnings are issued and avoid travel during the late‑afternoon to evening storm window.
