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 supercell that produced tornadoes earlier also produced a small tornado in rural Grant County. The tornado touched down near Dubbs Ranch south of Ashby and traveled north taking down power lines, breaking off and uprooting trees along a shelter belt, broke off fenceline, and moved cattle feeding equipment around.

The wider storm

An intense upper level low pressure system approached Western Nebraska on March 28th. Supercells developed quickly along a dryline extending from western Cherry County southward through western Chase County. The supercells produced tornadoes, hail, and strong winds during the late afternoon and evening hours.

Began near Ashby (41.8754, -101.9200).
