EF1 tornado in Ottawa County, Oklahoma

This is the second segment of a two segment tornado. In Ottawa County, this tornado uprooted trees. Based on this damage, maximum estimated wind in this segment of the tornado was 90 to 100 mph.

A strong upper level disturbance translated from the Southern Rockies into the Southern Plains on the 16th. Very moist and unstable air was in place across the Southern Plains as this system approached. Severe thunderstorms developed over western Oklahoma and northwestern Texas during the afternoon and moved eastward into eastern Oklahoma in the late evening. By the time the storms reached eastern Oklahoma, a well-organized squall line had evolved but due to very strong low level wind shear, multiple tornadoes occurred across the area along with widespread damaging wind. Locally heavy rainfall resulted in flash flooding in some areas through the early morning hours of the 17th.
