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 damage survey conducted by the National Weather Service in Fort Worth found that a tornado touched down near Happy Hill and traveled northeast approximately three miles to Pleasant Point where it dissipated. The tornado caused significant roof damage to several homes. Three homes were considered total losses. At least thirty other homes received minor to major damage. Many sheds and outbuildings were damaged or destroyed. Several trees were uprooted and at least two of them fell onto houses. Power lines were also downed along the track. This tornado was rated an EF-1 with maximum wind speeds between 90 and 95 MPH.

The wider storm

Several rounds of storms moved across north Texas on April 8th through 10th. Numerous reports of large hail were received on Tuesday evening. A lone supercell evolved during the afternoon hours of the 9th, producing tornadoes and large hail along its path. Later that evening and into Thursday morning a squall line tracked across north Texas, producing damaging winds and tornadoes into the morning hours.

Began near Lillian (32.4663, -97.2438).
