The episode as NWS OUN wrote it up.
An outflow boundary generated by thunderstorms over southwest Kansas moved into northwest Oklahoma. Afternoon heating along this boundary allowed for scattered thunderstorms. Although most produced non-severe gusty winds and heavy rainfall, one thunderstorm over Major county produced a wind gust that damaged power poles. No other damage was reported.
