EF1 tornado in Ottawa County, Oklahoma

This is the first segment of a two-segment tornado. In Ottawa County, this large tornado developed southwest of the E 40 Road and S 530 Road intersection. It moved northeast damaging a few homes, destroying outbuildings, snapping or uprooting trees, and snapping power poles. Based on this damage, maximum estimated wind in this segment of the tornado was 95 to 105 mph. This tornado was observed by multiple people, and it produced a radar-detected debris signature. The tornado continued into Cherokee County, Kansas.

Severe thunderstorms developed over northeastern Oklahoma during the afternoon hours of the 22nd, ahead of a cold front that moved into the area. Very strong instability and wind shear in the air mass ahead of the cold front allowed for the development of supercell thunderstorms, which affected the area through late evening. These supercells produced twenty-one documented tornadoes, including a significant tornado, large hail up to baseball size, damaging wind gusts, and locally heavy rainfall that resulted in flash flooding across northeastern Oklahoma.
