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

A National Weather Service damage survey team found evidence of EF-1 damage from a tornado in far northern Grayson County. The tornado began north of US 69 near Craft Road and moved northeastward into the Carpenter's Bluff area near the Red River. The damage in the area was mainly to trees. However, one church building near Carpenter's Bluff sustained roof damage. The tornado dissipated before reaching the Red River.

The wider storm

An active Spring weather pattern led to numerous severe thunderstorms, many of which produced tornadoes, across north Texas during Mother's Day Weekend. The prolonged period of strong to severe storms was made possible by a slow-moving upper level low pressure system which moved east from the Rockies through the Southern Plains. Activity began on Friday and continued through Mother's Day evening.

Began near South Gale (33.6700, -96.4600).
