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 few trees were snapped at their base and had large limbs broken off with the initial touchdown along FM 2625 just west of Highway 59. The tornado continued northeast paralleling FM 2625 causing sporadic tree damage until it reached the intersection of FM 2625 and Taylor Road. The tornado strengthened rapidly in a short timeframe causing EF2 damage to two residential homes and EF1 damage to a third. One house completely lost its roof while another had an entire room destroyed. The third home had its metal roof peeled off while sustaining partial wall failure. Numerous trees in the vicinity of the homes were completely toppled or had their tops sheared off. The tornado continued to the northeast where it intersected Blocker Road near FM 2625 causing various amounts of tree damage to several trees there. The tornado continued to the northeast dissipating over a logging road a mile to the east of Blocker Road. Maximum winds were estimated at 120-125 mph.

The wider storm

A very volatile atmosphere developed during the late afternoon...evening and overnight hours of April 26th across the Four State Region. An area of low pressure moved from the Texas Hill Country into Northeast Texas during the afternoon. Meanwhile, a warm front had moved northward from central Louisiana and was oriented west to east near the Arkansas/Louisiana state line. A dry line had moved just east of the I-35 corridor of North Central Texas and a strong cold front trailed the dry line. Very strong speed and directional shear was noted in the low and mid levels of the atmosphere such that supercells developed. Many of these produced tornadoes across the region. Other storms produced strong straight line wind gusts with bowing segments and large hail.

Began near Gill (32.4312, -94.3534).
