EF1 tornado in Delaware County, Oklahoma

This is the second segment of a two-segment tornado. This large tornado moved into Delaware County near the E 280 Road, where trees were uprooted. It moved northeast snapping and uprooting numerous trees, snapping power poles, destroying outbuildings, and damaging homes until it dissipated on Grand Lake near the Ottawa County line. Based on this damage, maximum estimated wind in this segment of the tornado was 100 to 110 mph.

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.
