What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 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 NWS Storm Survey determined that a EF-2 tornado began near the Argyle/Denton city line and traveled northeast for just over 1 mile. The tornado began in the Country Lakes subdivision where it significantly damaged the roofs of numerous homes. At least 10 to 12 homes sustained moderate damage. However, two homes lost part of their roofs on the order of EF-2 damage. To the northeast of the subdivision, near Johnson Lane, another home sustained minor roof damage and a barn was destroyed. Trees were also damaged along the path of the tornado. Maximum winds with this tornado were estimated between 115 and 125 MPH.

The wider storm

Three rounds of thunderstorms affected north Texas with 10 tornadoes confirmed. The atmosphere was highly unstable on this day and a High Risk was issued by the Storm Prediction Center for the northwestern counties of north Texas while a Moderate Risk covered much of the rest of north Texas. A strong upper level disturbance approaching from the west interacted with a dryline across the western portions of north Texas, and the first round of storms began to develop around 330 pm in the western counties. The first two rounds of storms remained along and north of Interstate 20 but the third round of storms later that night moved through most of the region as a line of storms. The most significant tornado occurred in the western limits of the city of Denton where EF-2 damage occurred. An EF-1 tornado also occurred in the city of Irving in Dallas County, and softball sized hail fell in the northern portions of the Metroplex. In the city of Dallas, one person died from electrocution after going outside around live, downed wires after a storm had passed.

Began near Argyle (33.1359, -97.1911).
