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 developed west of the S 560 Road and north of the E 220 Road, where large tree limbs were snapped. The tornado moved northeast and dissipated near Grand Lake, south of the E 170 Road. Several homes were damaged, a number of outbuildings were destroyed, trees were uprooted, and numerous large tree limbs and power poles were snapped in the path. Based on this damage, maximum estimated wind in the tornado was 95 to 105 mph.

The wider storm

Scattered severe thunderstorms developed over north central Oklahoma during the late afternoon of the 30th, ahead of an approaching cold front. These storms developed eastward into eastern Oklahoma during the evening, and eventually evolved into a squall line. One thunderstorm developed just ahead of the organizing line of storms, and became a supercell that produced damaging wind and a couple tornadoes in Ottawa County before being absorbed into the squall line.

Began near Fairland (36.7030, -94.8820).
