What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

This tornado started in southwest Arkansas county , or just west of Lumsdens Reservoir, and tracked northeast for 7 miles, moving along Jacobs Lake, and dissipating just before U.S. Hwy 165, in between Dewitt and Gillett. The primary damage was to trees along this path. Limited access to portions of the track was noted due to nearby lake and property access.

The wider storm

At the surface, a front was oriented from southwest to northeast across the state which would help focus the severe weather threat across northern Arkansas. As the upper level storm system moved closer to the area, severe storms developed during the afternoon of March 6th through the morning of the 7th. One main supercell thunderstorm travelled from southeast Johnson County to Randolph County and was responsible for multiple tornadoes through the evening of March 6th. Some additional storms produced mainly weak tornadoes that evening into the early morning hours of the 7th.

Began near One Horse Store (34.1500, -91.4600).
