23 damage points were recorded along this path by NWS FWD, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EFU. The highest wind the damage implies is 85 mph.

• Quite a few large limbs snapped along fence line.
• Large limbs snapped. Can see more tree damage further north onto property.
• Tree damage on both side of the road
• On both sides of the road.

On the afternoon of May 18, scattered thunderstorms ignited over the Big Country, initiated by an upper trough digging southeast over the Intermountain West. These storms formed along a dryline and rapidly intensified, spreading east into western North Texas. Several of these storms produced large hail, damaging winds, and tornadoes. A total of 6 tornadoes were surveyed were Eastland to Parker counties: one EF-Unknown, three EF-0s, and two EF-1s.

An EF-0 tornado with maximum wind speeds of 85 mph moved east along Gilbert Pit Road and Cougar Road in southwestern Parker County, with snapped large limbs observed along both of these roads. A barn was also destroyed along Gilbert Pit Road near the start of the track. Based on the observed damage and assessment of radar data, the tornado took a sharp northwest turn, causing some tree damage further north on Gilbert Pit Rd, with several large limbs and small trunks split and snapped on the Hill Cemetery property where the tornado likely dissipated.

27 minutes of warning. NWS FWD issued a tornado warning for this county at 01:09 UTC, 27 minutes before the tornado touched down, in force until 02:15 UTC.

The county was under a tornado watch, issued at 21:30 UTC and running to 02:57 UTC.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 01:00 UTC.

42 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
